According to a 2024 report from the EFF and ACLU, over 85% of big city police departments are using Automated License Plate Readers (ALPRs), weaving together a massive surveillance net. This tech is everywhere now, and when you add the explosion of biometrics into the mix, it’s forcing a head-on collision between the demand for more security and our basic rights to privacy. The central problem is figuring out how to get the real security benefits from these tools without building a society of constant, unchecked surveillance.
Key Takeaways
- ALPRs log every car’s movement, creating huge databases that show exactly where you go and when, a pattern of life that raises obvious and serious privacy issues.
- Fast-moving biometric tech like facial recognition makes it possible to identify you in public without you even knowing, effectively killing the idea that you can just be an anonymous face in a crowd.
- The law is so far behind the technology that huge regulatory gaps have opened up, meaning police can deploy ALPR and biometric systems faster than we can write rules to protect people’s rights.
- There are no consistent rules for how long this data is kept. Some departments delete it in weeks while others hold it for years, which dramatically increases the risk of it being stolen or used improperly.
- The only way to balance security and privacy is with real oversight, strict rules to delete data quickly (data minimization), and total transparency with the public.

72% of Americans are Concerned About Government Surveillance Using Biometrics
When a 2025 Pew Research Center survey shows that 72% of Americans are worried about government biometric surveillance, you know it’s a mainstream concern cutting across all political lines. In my own work, the first things people ask are always, “Who sees this data?” and “How long is it stored?” The amount of data being collected is hard to wrap your head around. Think about every car at a single intersection in downtown Atlanta getting its plate scanned and logged with a timestamp, then add facial recognition in parks, airports, and even stores. This collection goes far beyond just catching a suspect. It builds a detailed map of your life, your daily commute, your doctor’s appointments, your social circles. The real fear is “mission creep,” where data gathered for one specific purpose (like a stolen car alert) gets used for something completely different years down the road without anyone ever knowing or agreeing to it. We’ve always had a baseline assumption of anonymity in public, and this technology is steadily chipping away at that foundation.
ALPR Data Retention Periods Range from Days to Indefinitely Across Jurisdictions
The wild west of data retention policies is one of the biggest fights around ALPRs. A 2024 Brennan Center for Justice analysis found that while an agency like the Georgia Department of Public Safety (DPS) might delete non-hit data after 30 days, local departments often keep it for years, or forever. This patchwork is a disaster because your privacy rights can literally change just by driving across a county line. Keeping data for years massively increases the odds it will be hacked, exposed in data breaches, or used for things it was never intended for. For example, by pulling together a few years of ALPR hits, you can map someone’s entire life, from their AA meetings to their political rallies. And this is happening now. The tech to do this is real and the data is often accessible, sometimes even by private companies. People argue that holding data longer helps solve more crimes, but I think that’s a bad trade. The immense privacy risk of keeping everyone’s location history forever just isn’t worth the slim chance of it helping an old case. After a few months, the investigative value of this old data drops off a cliff, but the risk to our privacy just keeps growing.
Only 16 States Have Complete Laws Governing ALPR Use
Even with ALPRs on every street corner, the laws governing them are few and far between. As of early 2026, an NCSL report found only 16 states have actual laws on the books for government ALPR use. Here in Georgia, there’s no single, strong statute that lays out the rules for collecting, storing, and sharing this data. This legal void means every police department just makes up its own rules, which is exactly why you get one county keeping data for years and the next for 90 days. Without state laws, agencies run on internal memos they can change anytime without public debate. When the tech can do things the law never imagined (like using traffic data in a divorce proceeding), ethics get left in the dust. If your data is misused, you have almost no legal standing to sue because there’s often no specific law being broken. We need laws with teeth, laws that define exactly what data can be collected, who gets to see it, and that mandate deletion after a short, fixed period.
Global Market for Biometric Systems Projected to Reach $90 Billion by 2028
The money tells the story. The global biometrics market is on track to hit $90 billion by 2028, according to a 2025 Grand View Research analysis. This isn’t just a business trend. It’s a full-blown societal shift to using your body as your password. From your phone to airport security at Hartsfield-Jackson, it’s everywhere. And while it’s convenient, you’re trading away a piece of your privacy that, unlike a password, you can never change if it’s stolen. The unique challenge is how fast this is all happening with so little public debate. When a big retailer starts using facial recognition, do you know where that data goes? Is it shared with the cops? Sold to advertisers? Good luck finding out, because companies aren’t required to tell you. The argument that this is just the price of progress ignores what we’re losing: our autonomy and the ability to move through the world without being constantly identified and tracked. We’re building a future where being anonymous in public is impossible, and we need to think a lot harder about whether that’s the world we really want.
Less Than 10% of ALPR Deployments Include Public Audit Mechanisms
A 2025 EPIC report revealed a damning fact: fewer than 10% of city ALPR systems have any kind of public audit process. This lack of outside review is a huge flaw, because without audits, we’re just supposed to trust that these powerful surveillance systems are being used correctly. We need independent oversight. This is all about building public trust. If the Fulton County Police Department is using ALPRs, residents have a right to know how the data is used and if there have been any problems. No auditing creates a black box where data goes in and decisions come out, but nobody outside the department knows what happens in between. When people feel they’re being watched by secret systems, they lose faith in local policing. Real accountability means independent auditors get full access and publish their findings, good or bad, for everyone to see. Without that, you’re just asking for abuse, from warrantless tracking to cops looking up their exes. This isn’t an academic exercise. The collision between security tech and personal freedom is a direct threat to our rights, and it demands strong laws, clear ethics, and public oversight now.
What is ALPR technology?
Automated License Plate Recognition (ALPR) systems are basically cameras that read your license plate, turn it into text, and log it with the time, date, and location. All this data gets funneled into big databases that police use for investigations or that cities use for traffic control.
How do biometrics impact individual privacy?
Biometrics like your face or fingerprint are used to identify you. The privacy problem is huge because this data is you, it can’t be changed like a password if it gets stolen. It also allows for constant surveillance in public without you ever knowing you’re being watched or agreeing to it.
Are there laws in Georgia specifically regulating ALPR use?
No, Georgia doesn’t have a specific, statewide law that covers how government agencies can collect, store, and use ALPR data. This lack of a single rulebook is why policies are all over the map from one police department to the next.
What are the main security benefits of ALPR and biometrics?
The big security wins are speed and efficiency. ALPRs help police quickly spot cars tied to crimes, find stolen vehicles, or track down missing people. Biometrics provide a more secure way to control access to buildings and help law enforcement identify people much faster.
What can individuals do to protect their privacy from these technologies?
You can push for stronger laws to regulate surveillance tech and support digital privacy groups that are fighting these battles. Pay attention to the privacy policies of the apps and services you use. Getting involved in local meetings when your town wants to buy this kind of tech is also a big deal.
