Google is Quietly Working on a Wearable Device for Preteens

Google is developing a wearable device for preteens under its Fitbit group as it attempts to capture a growing demographic of younger users who own wearable tech, three employees familiar with the project told Insider.

Internally code-named “Project Eleven,” the wearable is designed to help older kids form healthy relationships with their phones and social media, two of the employees said. One of them said the device could include safety features that would let parents contact their children and know their whereabouts.

Project Eleven may be an opportunity to capture a growing market of younger users who would otherwise grow up to become Apple loyalists.

Police Across US Bypass Warrants With Mass Location-Tracking Tool

As summer winds down, researchers warned this week about systemic vulnerabilities in mobile app infrastructure, as well as a new iOS security flaw and one in TikTok. And new findings about ways to exploit Microsoft’s Power Automate tool in Windows 11 show how it can be used to distribute malware, from ransomware to keyloggers and beyond.

Fog Reveal Tool Gives Law Enforcement Cheap Access to US Location-Tracking Data From Smartphones

The data broker Fog Data Science has been selling access to what it claims are billions of location data points from over 250 million smartphones to local, state, and federal law enforcement agencies around the US. The data comes from tech companies and cell phone towers and is collected in the Fog Reveal tool from thousands of iOS and Android apps. Crucially, access to the service is cheap, often costing local police departments less than $10,000 per year, and investigations by the Associated Press and Electronic Frontier Foundation found that law enforcement sometimes pulls location data without a warrant. The EFF conducted its investigation through more than 100 public records requests filed over several months. “Troublingly, those records show that Fog and some law enforcement did not believe Fog’s surveillance implicated people’s Fourth Amendment rights and required authorities to get a warrant,” the EFF wrote.

Virginia Police Routinely Use Secret GPS Pings To Track People’s Cell Phones

The nonprofit online news site Virginia Mercury investigated their state police departments’ “real-time location warrants,” which are “addressed to telephone companies, ordering them to regularly ping a customers’ phone for its GPS location and share the results with police.” Public records requests submitted to a sampling of 18 police departments around the state found officers used the technique to conduct more than 7,000 days worth of surveillance in 2020. Court records show the tracking efforts spanned cases ranging from high-profile murders to minor larcenies…. Seven departments responded that they did not have any relevant billing records, indicating they don’t use the technique. Only one of the departments surveyed, Alexandria, indicated it had an internal policy governing how their officers use cellphone tracking, but a copy of the document provided by the city was entirely redacted….

Drug investigations accounted for more than 60 percent of the search warrants taken out in the two jurisdictions. Larcenies were the second most frequent category. Major crimes like murders, rapes and abductions made up a fraction of the tracking requests, accounting for just under 25 of the nearly 400 warrants filed in the jurisdictions that year.
America’s Supreme Court “ruled that warrantless cellphone tracking is unconstitutional back in 2012,” the article points out — but in practice those warrants aren’t hard to get. “Officers simply have to attest in an affidavit that they have probable cause that the tracking data is ‘relevant to a crime that is being committed or has been committed’…. There’s been limited public discussion or awareness of the kinds of tracking warrants the judiciary is approving.” “I don’t think people know that their cell phones can be converted to tracking devices by police with no notice,” said Steve Benjamin, a criminal defense lawyer in Richmond who said he’s recently noticed an uptick in cases in which officers employed the technique. “And the reality of modern life is everyone has their phone on them during the day and on their nightstand at night. … It’s as if the police tagged them with a chip under their skin, and people have no idea how easily this is accomplished.”
The case for these phone-tracking warrants?

  • The executive director of the Virginia Association of Chiefs of Police tells the site that physical surveillance ofen requires too many resources — and that cellphone tracking is safer. “It may be considered an intrusive way of gathering data on someone, but it’s certainly less dangerous than physical tracking.”
  • A spokesperson for the Chesterfield County police department [responsible for 64% of the state’s tracking] argued that “We exist to preserve human life and protect the vulnerable, and we will use all lawful tools at our disposal to do so.” And they added that such “continued robust enforcement efforts” were a part of the reason that the county’s still-rising number of fatal drug overdoses had not risen more.

The site also obtained bills from four major US cellphone carriers, and reported how much they were charging police for providing their cellphone-tracking services:

  • “T-Mobile charged $30 per day, which comes to $900 per month of tracking.”
  • “AT&T charged a monthly service fee of $100 and an additional $25 per day the service is utilized, which comes to $850 per 30 days of tracking…”
  • “Verizon calls the service ‘periodic location updates,’ charging $5 per day on top of a monthly service fee of $100, which comes to $200 per 30 days of tracking.”
  • “Sprint offered the cheapest prices to report locations back to law enforcement, charging a flat fee of $100 per month.”

Silenced AirTags With Disabled Speakers Are Popping Up for Sale Online

The AirTag, a small, easy-to-carry device about the size of a quarter, relies on Apple’s Find My network which leverages millions of Apple devices to discreetly keep tabs on the location of the trackers and report that information back to each tag’s registered user. The general idea behind the AirTag was that users could attach one to their keys, their backpack, or to other valuable items, and be able to quickly locate them if lost. To prevent their misuse, such as using an AirTag to track someone without their knowledge, iOS users would be eventually notified if a tracker registered to someone else was nearby, while Android users would have to rely on an audible beep that would start chirping three days after an AirTag was separated from its owner.

The product was ripe for abuse — a concern we emphasized in our initial review of the AirTags — and a couple of months after their debut Apple addressed those concerns with promised updates that would see Android users getting similar notifications as iOS users when an AirTag was nearby through a new Tracker Detect app that allowed Android users to more easily spot the devices. And the timeframe for when the trackers would start beeping after being away from its registered owner was shortened to a “random time inside a window that lasts between 8 and 24 hours,” according to a CNET report.

Facebook Has Trackers in 25% of Websites and 61% of the Most Popular Apps

Megan Borovicka forgot all about her Facebook account after 2013, reports the Washington Post. “But Facebook never forgot about her.”
The 42-year-old Oakland, California, lawyer never picked any “friends,” posted any status updates, liked any photos or even opened the Facebook app on her phone. Yet over the last decade, Facebook has used an invisible data vacuum to suction up very specific details about her life — from her brand of underwear to where she received her paycheck… It isn’t just the Facebook app that’s gobbling up your information. Facebook is so big, it has convinced millions of other businesses, apps and websites to also snoop on its behalf. Even when you’re not actively using Facebook. Even when you’re not online. Even, perhaps, if you’ve never had a Facebook account.

Here’s how it works: Facebook provides its business partners tracking software they embed in apps, websites and loyalty programs. Any business or group that needs to do digital advertising has little choice but to feed your activities into Facebook’s vacuum: your grocer, politicians and, yes, even the paywall page for this newspaper’s website. Behind the scenes, Facebook takes in this data and tries to match it up to your account. It sits under your name in a part of your profile your friends can’t see, but Facebook uses to shape your experience online. Among the 100 most popular smartphone apps, you can find Facebook software in 61 of them, app research firm Sensor Tower told me. Facebook also has trackers in about 25 percent of websites, according to privacy software maker Ghostery…

Facebook got a notice when I opened Hulu to watch TV. Facebook knew when I went shopping for paint, a rocking chair and fancy beans. Facebook learned I read the websites What To Expect, Lullaby Trust and Happiest Baby. Over two weeks, Facebook tracked me on at least 95 different apps, websites and businesses, and those are just the ones I know about. It was as if Facebook had hired a private eye to prepare a dossier about my life. Why does Facebook think that’s okay? The company emailed me answers about how its tracking technology works, but declined my requests to interview its chief privacy officer or other executives about its alleged monopoly….

Who in their right mind thought they were signing up for this much surveillance back when they first joined Facebook?

The article points out that in 2014 Facebook began allowing its advertisers to target users based on websites they’d visited…and now also gathers more data about users from other companies. And “While many companies were using browser cookies, which could be easily cleared or blocked, Facebook tied what it learned to real identities — the names on our Facebook profiles.” And beyond that, companies “can report other identifying information to Facebook like your email to help it figure out who you are… If you’ve never had a Facebook account at all? It may still be watching.”

It’s a lucrative business, the Post points out. “In 2013, the average American’s data was worth about $19 per year in advertising sales to Facebook, according to its financial statements. In 2020, your data was worth $164 per year.”

What does Facebook know about your off-Facebook activity? You can find out at this URL.

If you just want to stop them from giving this information to advertisers, the right side of that page has an option to “Clear History — Disconnect off-Facebook activity history from your account.” But you then have to also click “More Options” and then “Manage Future Activity” to also stop them from later matching up more of your off-Facebook activity to your profile for advertisers.

If you try to select it, Facebook warns what you’ll be missing — that “Keeping your future off-Facebook activity saved with your account allows us to personalize your experience.” And proceeding anyways then generates a popup reminding you that “We’ll still receive activity from the businesses and organizations you visit. It may be used for measurement purposes and to make improvements to our ads systems, but it will be disconnected from your account.”

And apparently your activity on Oculus isn’t covered, and will still remain connected to your Facebook account.

Your Browsing History Can Uniquely Identify You

Researchers from Mozilla report in a study that web browsing histories (the lists of user visited websites) are uniquely identifying users (PDF). In their study that was the case for 99% of users. Treating web browsing histories like fingerprints, the researchers analysed how the users can be reidentified just based on the coarsened list of user-visited websites.

In doing so they upheld and confirmed a previous study from 2012, prompting the author of the original study to say that web browsing histories are now personal data subject to privacy regulations like the GDPR.

Sensitivity of web browsing history data questions the laws allowing ISPs to sell web browsing histories.

The now-vindicated author of the 2012 study added this emphatic note in their blog post. “Web browsing histories are personal data. Deal with it.”

Most Americans Think They’re Being Constantly Tracked, Study Finds

More than 60% of Americans think it’s impossible to go through daily life without being tracked by companies or the government, according to a new Pew Research study. It’s not just that Americans (correctly) think companies are collecting their data. They don’t like it. About 69% of Americans are skeptical that companies will use their private information in a way they’re comfortable with, while 79% don’t believe that companies will come clean if they misuse the information. When it comes to who they trust, there are differences by race. About 73% of black Americans, for instance, are at least a little worried about what law enforcement knows about them, compared with 56% of white Americans. But among all respondents, more than 80% were concerned about what social-media sites and advertisers might know. Despite these concerns, more than 80% of Americans feel they have no control over how their information is collected.

Pentagon testing mass surveillance balloons across the US

The US military is conducting wide-area surveillance tests across six midwest states using experimental high-altitude balloons, documents filed with the Federal Communications Commission (FCC) reveal.

Up to 25 unmanned solar-powered balloons are being launched from rural South Dakota and drifting 250 miles through an area spanning portions of Minnesota, Iowa, Wisconsin and Missouri, before concluding in central Illinois.

Travelling in the stratosphere at altitudes of up to 65,000ft, the balloons are intended to “provide a persistent surveillance system to locate and deter narcotic trafficking and homeland security threats”, according to a filing made on behalf of the Sierra Nevada Corporation, an aerospace and defence company.

The balloons are carrying hi-tech radars designed to simultaneously track many individual vehicles day or night, through any kind of weather.

A rival balloon operator World View recently announced that it had carried out multi-week test missions in which its own stratospheric balloons were able to hover over a five-mile-diameter area for six and a half hours, and larger areas for days at a time.

Ryan Hartman, CEO of World View, said that World View had also completed a dozen surveillance test missions for a customer it would not name, capturing data he would not specify.

“Obviously, there are laws to protect people’s privacy and we are respectful of all those laws,” Hartman said. “We also understand the importance of operating in an ethical way as it relates to further protecting people’s privacy.”

You’re very easy to track down, even when your data has been anonymized

The most common way public agencies protect our identities is anonymization. This involves stripping out obviously identifiable things such as names, phone numbers, email addresses, and so on. Data sets are also altered to be less precise, columns in spreadsheets are removed, and “noise” is introduced to the data. Privacy policies reassure us that this means there’s no risk we could be tracked down in the database. However, a new study in Nature Communications suggests this is far from the case. Researchers from Imperial College London and the University of Louvain have created a machine-learning model that estimates exactly how easy individuals are to reidentify from an anonymized data set. You can check your own score here, by entering your zip code, gender, and date of birth.

On average, in the U.S., using those three records, you could be correctly located in an “anonymized” database 81% of the time. Given 15 demographic attributes of someone living in Massachusetts, there’s a 99.98% chance you could find that person in any anonymized database. The tool was created by assembling a database of 210 different data sets from five sources, including the U.S. Census. The researchers fed this data into a machine-learning model, which learned which combinations are more nearly unique and which are less so, and then assigns the probability of correct identification.

How America’s Tech Giants Are Helping Build China’s Surveillance State

The OpenPower Foundation — a nonprofit led by Google and IBM executives with the aim of trying to “drive innovation” — has set up a collaboration between IBM, Chinese company Semptian, and U.S. chip manufacturer Xilinx. Together, they have worked to advance a breed of microprocessors that enable computers to analyze vast amounts of data more efficiently. Shenzhen-based Semptian is using the devices to enhance the capabilities of internet surveillance and censorship technology it provides to human rights-abusing security agencies in China, according to sources and documents. A company employee said that its technology is being used to covertly monitor the internet activity of 200 million people…

Semptian presents itself publicly as a “big data” analysis company that works with internet providers and educational institutes. However, a substantial portion of the Chinese firm’s business is in fact generated through a front company named iNext, which sells the internet surveillance and censorship tools to governments. iNext operates out of the same offices in China as Semptian, with both companies on the eighth floor of a tower in Shenzhen’s busy Nanshan District. Semptian and iNext also share the same 200 employees and the same founder, Chen Longsen. [The company’s] Aegis equipment has been placed within China’s phone and internet networks, enabling the country’s government to secretly collect people’s email records, phone calls, text messages, cellphone locations, and web browsing histories, according to two sources familiar with Semptian’s work.

Promotional documents obtained from the company promise “location information for everyone in the country.” One company representative even told the Intercept they were processing “thousands of terabits per second,” and — not knowing they were talking to a reporter — forwarded a 16-minute video detailing their technology. “If a government operative enters a person’s cellphone number, Aegis can show where the device has been over a given period of time: the last three days, the last week, the last month, or longer,” the Intercept reports.

Smartphones and Fitness Trackers Are Being Used To Gauge Employee Performance

The passive system incorporates an app known as PhoneAgent, which was developed by Prof. Andrew Campbell at New Hampshire’s Dartmouth College. Using the smartphone’s own sensors, that app continuously monitors factors such as the worker’s phone usage, physical activity level, geographical location, and the ambient light levels of their environment. PhoneAgent is also Bluetooth-linked to a fitness bracelet worn by the employee, which transmits data including their heart functions, sleep quality, stress levels, and calorie consumption. Additionally, Bluetooth locational beacons in the person’s home and workplace monitor how much time they spend at each place, and how often they leave their workstation.

All of the phone, bracelet and beacon data is transmitted to a cloud-based server, where it’s processed via machine-learning algorithms that were “trained” on the habits of people already known to be high- or low-level performers. When tested on 750 workers across the U.S. over a one-year period, the system was reportedly able to distinguish between individuals’ performance levels (in a variety of industries) with an accuracy of 80 percent. That number should rise as the system is developed further.

Google Chrome ‘Has Become Surveillance Software. It’s Time to Switch’

“You open your browser to look at the Web. Do you know who is looking back at you?” warns Washington Post technology columnist Geoffrey A. Fowler.

Over a recent week of Web surfing, I peered under the hood of Google Chrome and found it brought along a few thousand friends. Shopping, news and even government sites quietly tagged my browser to let ad and data companies ride shotgun while I clicked around the Web. This was made possible by the Web’s biggest snoop of all: Google. Seen from the inside, its Chrome browser looks a lot like surveillance software…

My tests of Chrome vs. Firefox unearthed a personal data caper of absurd proportions. In a week of Web surfing on my desktop, I discovered 11,189 requests for tracker “cookies” that Chrome would have ushered right onto my computer but were automatically blocked by Firefox. These little files are the hooks that data firms, including Google itself, use to follow what websites you visit so they can build profiles of your interests, income and personality… And that’s not the half of it. Look in the upper right corner of your Chrome browser. See a picture or a name in the circle? If so, you’re logged in to the browser, and Google might be tapping into your Web activity to target ads. Don’t recall signing in? I didn’t, either. Chrome recently started doing that automatically when you use Gmail.

Chrome is even sneakier on your phone. If you use Android, Chrome sends Google your location every time you conduct a search. (If you turn off location sharing it still sends your coordinates out, just with less accuracy.)

The columnist concludes that “having the world’s biggest advertising company make the most popular Web browser was about as smart as letting kids run a candy shop,” and argues that through its Doubleclick and other ad businesses, Google “is the No. 1 cookie maker — the Mrs. Fields of the web.”

Thanks To Facebook, Your Cellphone Company Is Watching You More Closely Than Ever

A confidential Facebook document reviewed by The Intercept shows that Facebook courts carriers, along with phone makers — some 100 different companies in 50 countries — by offering the use of even more surveillance data, pulled straight from your smartphone by Facebook itself.

Offered to select Facebook partners, the data includes not just technical information about Facebook members’ devices and use of Wi-Fi and cellular networks, but also their past locations, interests, and even their social groups. This data is sourced not just from the company’s main iOS and Android apps, but from Instagram and Messenger as well. The data has been used by Facebook partners to assess their standing against competitors, including customers lost to and won from them, but also for more controversial uses like racially targeted ads.

Some experts are particularly alarmed that Facebook has marketed the use of the information — and appears to have helped directly facilitate its use, along with other Facebook data — for the purpose of screening customers on the basis of likely creditworthiness. Such use could potentially run afoul of federal law, which tightly governs credit assessments. Facebook said it does not provide creditworthiness services and that the data it provides to cellphone carriers and makers does not go beyond what it was already collecting for other uses.

Two-Thirds of Consumers Don’t Expect Google To Track Them the Way It Does

Last summer, an AP investigation found that Google’s location tracking remains on even if you turn it off in Google Maps, Search, and other apps. Research from Vanderbilt professor Douglas Schmidt found that Google engages in “passive” data collection, often without the user’s knowledge. His research also showed that Google utilizes data collected from other sources to de-anonymize existing user data.

Digital Content Next, the trade association of online publishers, surveyed a nationally representative sample to find out what people expect from Google — and, as with a similar study we conducted last year about Facebook, the results were unsettling.

Our findings show that many of Google’s data practices deviate from consumer expectations. We find it even more significant that consumer’s expectations are at an all-time low even after 2018, a year in which awareness around consumer privacy reached peak heights.

The results of the study are consistent with our Facebook study: People don’t want surveillance advertising. A majority of consumers indicated they don’t expect to be tracked across Google’s services, let alone be tracked across the web in order to make ads more targeted.

There was only one question where a small majority of respondents felt that Google was acting according to their expectations. That was about Google merging data from search queries with other data it collects on its own services. They also don’t expect Google to connect the data back to the user’s personal account, but only by a small majority. Google began doing both of these in 2016 after previously promising it wouldn’t.

Unearthed Emails Show Google, Ad Giants Know They Break Privacy Laws

Privacy warriors have filed fresh evidence in their ongoing battle against real-time web ad exchange systems, which campaigners claim trample over Europe’s data protection laws. The new filings — submitted today to regulators in the UK, Ireland, and Poland — allege that Google and industry body the Interactive Advertising Bureau (IAB) are well aware that their advertising networks flout the EU’s privacy-safeguarding GDPR, and yet are doing nothing about it. The IAB, Google — which is an IAB member — and others in the ad-slinging world insist they aren’t doing anything wrong. The fresh submissions come soon after the UK Information Commissioner’s Office (ICO) revealed plans to probe programmatic ads. These are adverts that are selected and served on-the-fly as you visit a webpage, using whatever personal information has been scraped together about you to pick an ad most relevant to your interests. […] The ICO’s investigation will focus on how well informed people are about how their personal information is used for this kind of online advertising, which laws ad-technology firms rely on for processing said private data, and whether users’ data is secure as it is shared on these platforms.

Attackers Can Track Kids’ Locations Via Connected Watches

Over the last year of looking at kids GPS tracking watches we have found some staggering issues. With these devices it almost seems that having multiple security issues is the new normal.

While parents and guardians may get a feeling of security from using these devices, our testing and research shows it’s just that, a “feeling”.

A couple of years ago we bought and reviewed a number of smart kids tracker watches, including some Gator watches from TechSixtyFour.

After chatting to our friends at the Norwegian Consumer Council, who we know well through My Friend Cayla, we discovered they were working on exactly the same tech, by complete coincidence!

We decided to pause our project to avoid us duplicating their efforts. Shortly after, the Norwegian Consumers Council published the excellent ‘WatchOut’ research that demonstrated trivial access to kids GPS locations through vulnerable tracker watches, including the Gator.

It received plenty of press coverage and resulted in several kids tracker watches taking swift action to secure their systems.

A year on, we decided to have a look at the Gator watch again to see how their security had improved as a result of their actions.
TL; DR

Guess what: a train wreck. Anyone could access the entire database, including real time child location, name, parents details etc. Not just Gator watches either – the same back end covered multiple brands and tens of thousands of watches

The Gator web backend was passing the user level as a parameter. Changing that value to another number gave super admin access throughout the platform. The system failed to validate that the user had the appropriate permission to take admin control!

This means that an attacker could get full access to all account information and all watch information. They could view any user of the system and any device on the system, including its location. They could manipulate everything and even change users’ emails/passwords to lock them out of their watch.

‘The goal is to automate us’: welcome to the age of surveillance capitalism

The behaviour of the digital giants looks rather different from the roseate hallucinations of Wired magazine. What one sees instead is a colonising ruthlessness of which John D Rockefeller would have been proud. First of all there was the arrogant appropriation of users’ behavioural data – viewed as a free resource, there for the taking. Then the use of patented methods to extract or infer data even when users had explicitly denied permission, followed by the use of technologies that were opaque by design and fostered user ignorance.

And, of course, there is also the fact that the entire project was conducted in what was effectively lawless – or at any rate law-free – territory. Thus Google decided that it would digitise and store every book ever printed, regardless of copyright issues. Or that it would photograph every street and house on the planet without asking anyone’s permission. Facebook launched its infamous “beacons”, which reported a user’s online activities and published them to others’ news feeds without the knowledge of the user. And so on, in accordance with the disrupter’s mantra that “it is easier to ask for forgiveness than for permission”.

The combination of state surveillance and its capitalist counterpart means that digital technology is separating the citizens in all societies into two groups: the watchers (invisible, unknown and unaccountable) and the watched. This has profound consequences for democracy because asymmetry of knowledge translates into asymmetries of power.

Several Popular Apps Share Data With Facebook Without User Consent

Some of the most popular apps for Android smartphones, including Skyscanner, TripAdvisor and MyFitnessPal, are transmitting data to Facebook without the consent of users in a potential breach of EU regulations.

In a study of 34 popular Android apps, the campaign group Privacy International found that at least 20 of them send certain data to Facebook the second that they are opened on a phone, before users can be asked for permission. Information sent instantly included the app’s name, the user’s unique ID with Google, and the number of times the app was opened and closed since being downloaded. Some, such as travel site Kayak, later sent detailed information about people’s flight searches to Facebook, including travel dates, whether the user had children and which flights and destinations they had searched for. European law on data-sharing changed in May with the introduction of General Data Protection Regulation and mobile apps are required to have the explicit consent of users before collecting their personal information.

Chinese schools enforce ‘smart uniforms’ with GPS tracking system to monitor students

Chinese schools have begun enforcing “smart uniforms” embedded with computer chips to monitor student movements and prevent them from skipping classes.

Eleven schools in the south-west province of Guizhou have introduced the uniforms, which were developed by local tech firm Guizhou Guanyu Technology.

As students enter the school, the time and date is recorded along with a short video that parents can access via a mobile app.

Facial recognition further ensures that each uniform is worn by its rightful owner to prevent students from cheating the system.

Skipping classes triggers an alarm to inform teachers and parents of the truancy, while an automatic voice alarm activates if a student walks out of school without permission.

A GPS system tracks student movements even beyond the school grounds.

The two chips — inserted into each uniform’s shoulders — can withstand up to 500 washes and 150 degrees Celsius, the company told state media Global Times.

Alarms will also sound if a student falls asleep in class, while parents can monitor purchases their child makes at the school and set spending limits via a mobile app, according to the company’s official website.

Parents are using GPS ankle monitors to track their teenagers like criminals

There’s no shortage of GPS trackers for parents who want to keep tabs on their children’s driving. After all, car accidents are the leading cause of death for American teens. For some parents, that’s enough.

For others, nothing but a full-on ankle monitor—the kind used to track people released on bail or parole—will do.
Frank Kopczynski, the owner of Tampa Bay Monitoring (in fact located in Clearwater, Florida), also runs Action Plus Bail Bonds. He said the biggest challenge in strapping an ankle monitor to teenage non-offenders is whether they can remove it themselves.

“We provide a bracelet that is near-impossible to cut off,” Kopczynski told Quartz. “It also allows us to have two-way communication and gives us the option of sounding a piercing alarm.”

Along with the 95-decibel siren, if a teen is out past curfew, their parents can call Tampa Bay Monitoring’s office, and Kopczynski or one of his employees will activate the ankle monitor’s speaker and tell the child it’s time to get home or the police will be called. Hearing “this god-like voice out of nowhere” is generally effective, said Kopczynski; since the system is two-way, staff can also monitor the teen covertly.

The electronic monitoring industry has more than doubled in size in recent years, and has expanded well beyond its initial market of people on bail or parole. For example, immigrants detained by US authorities and put on an electronic monitoring program are required to pay extremely high fees—$880 for activation plus $420 a month— while they await their hearings.
