On Flock License Plate Tracking Cameras

A recent story of a writer who was mistakenly identified, tracked, and arrested using data from Flock cameras has gone viral.

The New Jersey plates that were allegedly stolen from the LA dealer were 34 03 DTM, not 34 10 DTM. But when the police report was created and the plate was entered into Flock’s system, it was just recorded as 34 DTM. Just the five large characters, no little number in the middle. And Flock’s AI tech wasn’t registering that non-standard little number when it began picking up the Range Rover around town. It just saw 34 DTM in large type and started alerting the local police.

As we all stood there shaking our heads, including my wife, who was finally allowed to join me, I connected the final dot. A lot of vehicles in JLR’s media fleet have a New Jersey manufacturer plate with the same alphanumeric structure­34 ## DTM­and Officer Ganshyn observed that meant it was now a nationwide issue. Anywhere a police department has a partnership with Flock, any other JLR-owned car with the same plate structure is going to get flagged as stolen. In fact, four other 34 ## DTM cars were being tracked around Minnesota that week, according to Officer Ganshyn. I was just the first one to get nabbed. The only way to stop it would be for the LAPD to correct their initial report and update Flock’s system, which Jaguar Land Rover was now racing to make happen following the phone call.

Flock has responded to the bad press. First, they affirmed that their systems were working correctly, and blamed the police:

The obvious question was that Flock cameras were looking for 34 DTM, and the plate on the car I was driving was 34 10 DTM. Why was that flagged as a match?

“The way that the ML [machine learning] works is it correctly read what it was supposed to read. It was fed those characters that you said, 34 DTM, and it spit back out [a result] with the characters, 34 DTM,” Thomas said. “It was asked, can you find this? And it did find that. It just didn’t say if there’s more here, then don’t do it. It just simply said, is it there? And the answer was yes.”

He explained that even if the 10 was normal size, Flock would still have flagged it as a match, because that’s how they’ve set it up according to law enforcement’s requests. Sometimes partial plates are all they have to go on at first.

“The way that law enforcement likes to use these tools is, if any of the characters that they have put into these hot lists get read, they want to get those alerts,” he said. “Now, what we try to train officers to do is to do what you said, which is to verify that 34 DTM is what I’m looking for, and what I’m seeing is 34 10 DTM.”

Second, Flock’s CEO has apologized for calling privacy advocates terrorists:

The CEO of Flock Safety, the company that runs an enormous network of cameras used by police departments across the U.S., hasn’t been shy about taking on Flock’s critics. Last year, he even called one group that tracks the location of Flock cameras “terrorists.” But he’s had a change of heart. Or, at the very least, a change in PR strategy.

Meanwhile, the police are using (alternate source) the Flock camera network to track people in addition to cars:

Police departments around the country have used Flock cameras at least hundreds of times to search for specific people, not cars, using searches such as “heavy-set male with a black and white hat,” “person on skateboard,” and “person wearing orange vest and construction hat,” according to data reviewed by 404 Media. Sometimes searches reference a target’s race or signs of their political affiliation.

And, like all police surveillance technologies, there are abuses.

Details of Alan Turing’s Voice Encryption System

Really interesting piece of cryptographic history:

In November 2023, a large cache of his wartime papers—nicknamed the “Bayley papers”—was auctioned in London for almost half a million U.S. dollars. The previously unknown cache contains many sheets in Turing’s own handwriting, telling of his top-secret “Delilah” engineering project from 1943 to 1945. Delilah was Turing’s portable voice-encryption system, named after the biblical deceiver of men. There is also material written by Bayley, often in the form of notes he took while Turing was speaking. It is thanks to Bayley that the papers survived: He kept them until he died in 2020, 66 years after Turing passed away.

Protecting Privacy in an AI Era

Daniel Solove argues in the Wall Street Journal (alternate link) that giving people control of their personal data is not an effective way to regulate privacy in this era. Instead, we need to hold companies accountable for their actions, similar to what we do with food and drug companies. Measures such as rigorous data minimization, fiduciary duties, liability for negligent or reckless technological design, liability for algorithms that cause harm, and multi-stakeholder review of technologies will be far more effective.

A Video Screen That Is Also a Camera

Amazing:

Researchers from ETH Zurich in Switzerland, however, managed to create a new type of pixel that can simultaneously do both. This hypercharged pixel, called a Fourier pixel, can generate and sense arbitrary light fields and tap into a pixel’s full potential for carrying information by manipulating light’s intensity, oscillation phases, and polarization. The team reported its findings in a paper published yesterday in Nature.

We are one step closer to 1984 technology:

The telescreen received and transmitted simultaneously. Any sound that Winston made, above the level of a very low whisper, would be picked up by it; moreover, so long as he remained within the field of vision which the metal plaque commanded, he could be seen as well as heard. There was of course no way of knowing whether you were being watched at any given moment.

AI Data Centers and the Concentration of Wealth

This essay was written with Nathan E. Sanders, and originally appeared in The Guardian.

Opposition to AI data centers has emerged as a primary theme in US politics, one that—surprisingly—doesn’t fall along party lines. We applaud people coming together for constructive debate on any issue, and agree that communities need to evaluate whether any economic benefits these data centers bring is worth their costs. Still, we worry that a focus on data centers obscures the larger impacts of AI on people’s lives: the concentration of power of AI companies, and their widespread political and financial influence.

Local data center opposition is grounded in legitimate concerns about misallocation of land resources when housing is at a premium, pressures on already higher energy prices, and localized environmental impact. Unlike other resource-consuming and polluting industrial facilities, data centers produce very few jobs. The fact that US opposition to data centers seems to be most fierce among lower-income communities reflects righteous indignation with an inequitable bargain, where tech companies and developers profit from exploiting local resources but offer little in return. On a global scale, their carbon footprint could grow unsustainably if usage accelerates. And all this is in aid of a technology that many fear will propagate misinformation, take their jobs, or even cause existential risks for humanity.

For some, data center opposition may feel like the only tangible mechanism for registering their concern, disapproval, or even anger about AI. The problem is that this may be exactly what the AI companies are banking on. They can overcome the protest when it matters to them, and live with a significant fraction of proposals being defeated. More importantly, focusing political opponents on the data center issue obscures the bigger prize they’re after.

While there is a staggering three-quarters of a trillion dollars being spent on data center infrastructure by US companies this year alone, this investment should be taken in perspective. The market for enterprise software, for example, is about twice this size. And it’s small compared with what these companies actually want.

AI companies have their eyes set on capturing all the value created by entire industries. The technology has arguably already conquered customer service and consumer sales. But on the horizon are bigger targets, such as enterprise software development, creative design, management and even legal services. In AI companies and their allies’ vision of the future, AI replaces teachers and doctors. The companies would rather spend time fighting resistance to how fast they are building computing infrastructure than dealing with issues of how their products should be used in those fields, or how those fields should be protected from their products.

And while data center opposition campaigns have been successful in building widespread appeal, their effectiveness in the US is mixed. They seem to be most successful when organizing against speculative, early-stage data center proposals that have a relatively low likelihood to ever see fruition. Meanwhile, advanced-stage, well-capitalized data center projects have proven to have the resources to overcome local opposition. An OpenAI- and Oracle-backed facility in Saline township, Michigan, is breaking ground on construction even after local officials voted to reject it. The developers sued the town of 3,000 and forced a settlement that involved their project going forward. Meanwhile, the Trump administration, a vigorous ally of corporate AI, has signaled its willingness to advance AI infrastructure development by overriding state objections and even using federal lands.

Also consider that rampant data center development may be a momentary spike rather than a longstanding concern. Demand for the centralized computing that data centers provide may well decline over time. The leading Chinese labs, such as Z.ai, are innovating in technical mechanisms to make frontier-class models smaller and cheaper to run. AI power users have become adept at miniaturizing open weight models, ones published free for anyone to download and use, to run locally on their own computers. Apple and Google both support infrastructure stacks for running AI models directly on mobile phones. It could be that the current mania for data centers will look like the fiber optic cable bubble from the early 2000s, as demand shifts to smaller models and AI usage on people’s own devices.

For those concerned primarily with affordability and environmental protection, singling out data center construction is misplaced. Energy rates and inflation today seem to be most visibly affected by the US-Iran war. The US is disinvesting in long-term energy security by ceding the renewable energy industry to China and actively cancelling climate commitments. Consider that 10% of global carbon emissions stem from heating buildings, which dwarfs energy use by AI and could be cut fivefold by using heat pumps powered by renewable energy. With respect to housing affordability, federal housing subsidies have changed little over three decades, in inflation-adjusted terms, even as housing costs have spiked and homeowners have enjoyed robust tax incentives.

As for AI itself, the concentration of power and wealth in these tech companies is the greatest existential risk facing society today. This means we must limit corporate power, especially corporations’ ability to exploit the public and manipulate our political system.

Opposing data centers should be just a starting point. We can advocate for states to regulate AI, to reject irresponsible uses of the technology, and shape corporate behavior. We can fight for AI computation to be taxed, so that the public can capture some of the profit of AI use while also forcing AI companies to internalize more of the energy and environmental consequences associated with its use. And we all can join the global movement for Public AI, an alternative ecosystem for AI that is developed under public control with an incentive structure to create public benefit rather than private profit.

The US midterm elections present ample opportunity for those seeking to control the AI political agenda. In the recent New York congressional Democratic primary, PACs linked to the dueling AI companies Anthropic and OpenAI spent millions of dollars lobbying for or against “AI safety“, the idea that we must urgently monitor and prevent people from using AI to cause catastrophic harms. We’re already seeing a similar dynamic play out in races in Massachusetts and other states.

Why would Anthropic and OpenAI—bitter industry rivals but fundamentally on the same side politically—support opposing viewpoints? Because they both ultimately profit from the mystique: the idea that their products are so powerful that controlling those products is the world’s most important challenge. Here’s the typical read on the dynamic. To one side (backed by OpenAI affiliates), “safety” comes from the appearance of US industry dominating AI innovation, under the slow-moving control of federal lawmakers (and without pesky state regulators in the way). To the other side (backed by Anthropic), “safety” means a heavier regulatory framework that plays to Anthropic’s posturing as the ethics- and compliance-focused AI vendor. In both cases, it’s more marketing than principled concern about safety.

Political organizers should call out and reject the AI companies’ framing of the debate, and reorient campaign agendas around populist resistance to corporate concentration of wealth and power. When AI companies pump millions into legislative races, the result should not be hyperbolic discussion of AI superintelligence. And when a plot of land in a small town is pitched as a data center site, the debate should be about more than the local costs and benefits. It should include out-of-control money in politics, and Citizens United-proof solutions to limit corporate influence like public financing and state regulation.

We all have a vested interest in what’s on the policy agenda, and what the outcomes are. Today, the greatest risk AI poses to society is the exacerbation of inequality and the concentration of wealth. The real problem is trillion-dollar AI companies and their trillionaire oligarchs cozying up to political power in Washington and governments worldwide, and using their money to enact their agenda over the popular will of the people. This is the issue we’d like to see put front and center, and it requires solutions much more extensive than slowing data center development.

AI Surveillance and Social Progress

In the near future, AI-powered surveillance systems will be able to track everything we do in public, and much of what we do in private. And if we do something wrong—shoplift, litter, jaywalk, you name it—the system will notice, retain it, tie it to your official government record, communicate that fact to you, and provide real-time alerts to any relevant authorities… and maybe also to the general public.

Think of these systems as automated speed cameras, but on steroids. Only they’ll enforce not just speed limits, but any other rule you can imagine. And you won’t receive a ticket weeks later by mail; you’ll be informed about and fined for your violation immediately.

These systems will combine powerful AI, public and private surveillance via real-time facial recognition technology and digital tracking, mass databases and highly personalized enforcement. If deployed at scale, they will have profound chilling effects not just on personal freedoms, but democracy and social progress itself.

China has been developing its surveillance infrastructure for years. The country has over 600 million surveillance cameras, increasingly powered by AI and facial recognition to enforce legal and social rules. Take the case of Lao Duan, a Chinese citizen blacklisted by the system after he lost his job and was unable to repay a series of loans. When he visited Beijing, the city’s AI surveillance system identified him by his face at a major intersection and displayed his face, name and citizen ID number on a large electronic billboard nearby with a message that he was an untrustworthy person. Similar systems are now being deployed across China and integrated with its infamous online monitoring, censorship and social credit systems.

AI surveillance is now being experimented with in North America, South America, Europe, Asia and Africa. According to a new report, the US Department of Homeland Security is rapidly increasing its use of AI-based surveillance, including facial recognition and the monitoring of social media accounts, to keep tabs on immigrants, dissidents, journalists, legal observers and protesters. While the systems are ostensibly used to maintain security and public safety, the real aim is often social control. Larry Ellison, CEO of Oracle—a powerful tech giant that works closely with the Trump administration—has said: “Citizens will be on their best behavior because we’re constantly recording and reporting.” The chilling effects are the point.

AI surveillance raises a range of public policy challenges: technical biases, unauditable systems, and inflexible automated law and social rule enforcement that can promote discrimination and undermine transparency, accountability and the rule of law. But we believe the most urgent and long-term impact will be its broader chilling effects.

In a new book, Chilling Effects: Repression, Conformity, and Power in the Digital Age, Jon Penney explains how surveillance, technology and power can be weaponized to influence behavior at scale. Surveillance, personalization, uncertainty and authority are all key mechanisms to increase the scale and impact of chilling effects. They cause people to self-censor their words and actions, to become more conformist and compliant and thus easier to manage and control. And the effects are additive: the more mechanisms employed, and the more powerful the form, the greater the chill.

Computerization has long allowed data collectors to track our locations, collect lists of whom we communicate with, and monitor our spending habits—unless we use cash. What’s new is an unprecedented fusion of each of these mechanisms, persistent and unrelenting. AI brings an analytical ability to spy on the contents of our communications, and to answer sophisticated questions about our whereabouts and activities: actions that previously required human analysts are now automated. The result will be a kind of supercharged societal level of chilling effects where fear, self-censorship and groupthink reign, and dissent, creativity and innovation become increasingly rare.

In this atmosphere of fear and conformity, risky ideas, social activism and self-reinvention—especially by disfavored groups and targeted populations—are also chilled. This will have long-term effects on social progress.

Consider the relatively recent societal normalization of same-sex relationships and the recreational use of marijuana. Over the decades, those ideas slowly progressed from being both immoral and illegal, to moral but still illegal, and finally to both moral and legal. But in order for any of that to happen, there had to be a counterculture that was able to experiment and eventually demonstrate to the world that morality could change over time. To the extent that AI surveillance chills this sort of experimentation in public or in private, social progress becomes impossible.

There are no real historical precursors to this; these technologies are too new. Even the most notorious and large-scale domestic surveillance program in US history, the FBI’s use of wiretapping, physical mail opening, informants and paper index cards to track alleged communists during the 1950s and 1960s, appears genuinely archaic in light of modern AI-enhanced surveillance. So does East Germany’s human-centric surveillance network during the cold war. Only science fiction, from the likes of George Orwell or Aldous Huxley, comes close. But even Big Brother’s “telescreen” feels decidedly mid-20th-century by comparison.

But we need not sit idly. Now that we recognize the danger of AI-enhanced mass surveillance, we can make the policy choices not to implement it. Bans on facial recognition and other forms of identification tech can slow development; robust new privacy and data protections can restrict data tracking and retention; AI regulations can curtail its most invasive uses; and structural reforms can help us scrutinize and break up powerful state/tech cartels that pave the way for technological excesses like AI surveillance.

The chill of AI-powered mass surveillance will suffocate the very foundations of healthy democratic societies. But we can still choose a different path.
