DOJ emails reveal stingray surveillance misuse, leading to ‘accidental’ spying

stingrayHang on, we’re not talking about those kinds of stingrays. Though, considering some odd underwater tech activities recently, it wouldn’t be entirely impossible. No, the stingray we’re referring to is a device federal investigators have been quietly using to mimic the presence of a cell phone tower, allowing them to triangulate the precise location of particular cell phones and their users. The investigators, however, failed to mention that fact to courts that would require them to gain permission before doing so.

The stingray devices can be used not only to locate particular cell phones – with such precision that can reveal down to the exact room in a building – but also intercept conversations being held on the tracked devices. If this doesn’t already get your Big Brother paranoia going, it turns out the stingrays also sweep up user data of nearby cellphones in the process.

Stingrays are hardly new to law enforcement authorities, and have been used for years. What is particularly concerning about this discovery of stingray usage is the apparent lack of legal oversight. Traditionally, stingray usage required advance notice of the deployment so a judge can review the evidence and see whether such activity is warranted, and to ensure that privacy safeguards and standards are met. That, apparently, is not always the case.

The American Civil Liberties Union uncovered this activity as the result of a Freedom of Information Act search regarding a particular case involving the technology. In a blog post published earlier this week, ACLU staff attorney Linda Lye explained that a collection of emails received as part of the FOIA request revealed that “the federal government was routinely using stingray technology in the field, but failing to ‘make that explicit’ in its applications to the court to engage in electronic surveillance.”

It’s not only the ACLU that finds this disturbing, Lye continues. “When the magistrate judges in the Northern District of California finally found out what was happening, they expressed ‘collective concerns,’ according to the emails,” she wrote. Such concerns may have been expressed too late, however. Lye notes that the email chain that reveals the stingray use is dated May 2011, three years later than the suspected use in the case the ACLU is investigating. Or, in Lye’s words, “the government was not ‘forthright’ in its applications to federal magistrate judges for at least three years.”

In the legal defense the government has filed in the ACLU case, authorities claimed that the stingray’s use without proper oversight was simply a mistake made due to “a relatively new technology,” but the emails now released definitely suggest otherwise. How long have authorities been circumventing guidelines for surveillance within the U.S. – and, more worryingly, just how much information on those not officially under surveillance has been collected “by accident”?

Digital Trends’ Tech For Change CES 2023 Awards
Digital Trends CES 2023 Tech For Change Award Winners Feature

CES is more than just a neon-drenched show-and-tell session for the world’s biggest tech manufacturers. More and more, it’s also a place where companies showcase innovations that could truly make the world a better place — and at CES 2023, this type of tech was on full display. We saw everything from accessibility-minded PS5 controllers to pedal-powered smart desks. But of all the amazing innovations on display this year, these three impressed us the most:

Samsung's Relumino Mode
Across the globe, roughly 300 million people suffer from moderate to severe vision loss, and generally speaking, most TVs don’t take that into account. So in an effort to make television more accessible and enjoyable for those millions of people suffering from impaired vision, Samsung is adding a new picture mode to many of its new TVs.

Relumino Mode, as it’s called, works by adding a bunch of different visual filters to the picture simultaneously. Outlines of people and objects on screen are highlighted, the contrast and brightness of the overall picture are cranked up, and extra sharpness is applied to everything. The resulting video would likely look strange to people with normal vision, but for folks with low vision, it should look clearer and closer to "normal" than it otherwise would.
Excitingly, since Relumino Mode is ultimately just a clever software trick, this technology could theoretically be pushed out via a software update and installed on millions of existing Samsung TVs -- not just new and recently purchased ones.

AI turned Breaking Bad into an anime — and it’s terrifying

These days, it seems like there's nothing AI programs can't do. Thanks to advancements in artificial intelligence, deepfakes have done digital "face-offs" with Hollywood celebrities in films and TV shows, VFX artists can de-age actors almost instantly, and ChatGPT has learned how to write big-budget screenplays in the blink of an eye. Pretty soon, AI will probably decide who wins at the Oscars.

Within the past year, AI has also been used to generate beautiful works of art in seconds, creating a viral new trend and causing a boon for fan artists everywhere. TikTok user @cyborgism recently broke the internet by posting a clip featuring many AI-generated pictures of Breaking Bad. The theme here is that the characters are depicted as anime characters straight out of the 1980s, and the result is concerning to say the least. Depending on your viewpoint, Breaking Bad AI (my unofficial name for it) shows how technology can either threaten the integrity of original works of art or nurture artistic expression.
What if AI created Breaking Bad as a 1980s anime?
Playing over Metro Boomin's rap remix of the famous "I am the one who knocks" monologue, the video features images of the cast that range from shockingly realistic to full-on exaggerated. The clip currently has over 65,000 likes on TikTok alone, and many other users have shared their thoughts on the art. One user wrote, "Regardless of the repercussions on the entertainment industry, I can't wait for AI to be advanced enough to animate the whole show like this."

4 simple pieces of tech that helped me run my first marathon

The fitness world is littered with opportunities to buy tech aimed at enhancing your physical performance. No matter your sport of choice or personal goals, there's a deep rabbit hole you can go down. It'll cost plenty of money, but the gains can be marginal -- and can honestly just be a distraction from what you should actually be focused on. Running is certainly susceptible to this.

A few months ago, I ran my first-ever marathon. It was an incredible accomplishment I had no idea I'd ever be able to reach, and it's now going to be the first of many I run in my lifetime. And despite my deep-rooted history in tech, and the endless opportunities for being baited into gearing myself up with every last product to help me get through the marathon, I went with a rather simple approach.
