The False Choice Between Privacy and Safety in Smart Surveillance

Is there a real choice between privacy and safety in surveillance? As artificial intelligence continues to advance, we’ve seen an increased focus on privacy. A 2019 report from the American Civil Liberties Union contains an ominous warning: Artificial intelligence-enabled video surveillance will soon compromise our civil liberties in a dangerous way. Consider a false choice between privacy and safety in smart surveillance.

The ACLU isn’t wrong: Some technology could indeed contribute to this dystopian vision.

A dystopia is a community or society that is undesirable or frightening — translated as “a bad place.” Some systems attempt to use technology that’s not yet advanced enough, raising the specter of misuse; others invade the privacy of citizens, all for minimal security benefits.

But there are avenues of AI video surveillance that can bring greater public safety without sacrificing civil liberties.

The key is using AI to enable human security professionals to do their jobs better, not overextending AI’s capabilities to take over their jobs entirely. I see AI surveillance existing within three main categories: behavioral analysis, facial recognition, and object detection. The first two categories raise concerns. To understand what makes the last more viable, it’s important to break down the issues with the others.

AI Isn’t Advanced Enough for Behavioral Analysis

Behavioral analysis is essentially an attempt to detect so-called suspicious behavior before any crimes are committed. The ACLU’s “Th­e Dawn of Robot Surveillance” report touches on a few areas here: human action recognition, anomaly detection, and contextual understanding. Contextual understanding is the most advanced, but researchers have yet to make it genuinely feasible, and it’s unclear whether current technology provides a path to this type of general intelligence.

AI can’t infer — it can only recognize patterns.

Some companies are already putting this technology into action, however. The New York Police Department has partnered with Microsoft to produce what it calls the Domain Awareness System. Part of the system would involve smart cameras that aim to detect suspicious behaviors.

The one area where behavioral analysis may be feasible is in detecting theft, and that’s primarily due to the lack of other viable options.

Without Amazon Go-style camera installations, tracking every item in a store isn’t possible — so the next-best option is to guess whether a person is suspicious based on certain detected behaviors. But that, in itself, draws civil liberties concerns. The ACLU report notes the problems inherent in identifying “anomalous” behavior and people.

Facial Recognition Creates a Target for Bad Actors

Facial recognition works significantly better than behavioral analysis, and many law enforcement agencies and security firms already use the technology. That’s not to say it’s anywhere near perfect. False positives are — especially when it comes to people of color. As a result, cities like San Francisco have banned the use of facial recognition software by local government agencies.

Even if facial recognition technology was 100% accurate, it still might not stop the worst of crimes.

Acts of violence such as mass shootings are regularly perpetrated by students, family members, employees, or customers: in other words, people who “” in the location. It’s unlikely that a facial recognition system would flag these individuals.

Is it really just a “false choice” for facial recognition to protect people in their own neighborhoods and homes?

Then, there’s the severe invasion of privacy that’s required to make this technology work. To identify a suspect, facial recognition requires an external database of faces as well as personally-identifying information to match the face to a name. A database like that is an attractive target for bad actors.

We Don’t Have to Sacrifice Privacy for Safety

The issues associated with behavioral analysis and facial recognition all lead back to the human element of threat detection. That’s where object detection differs. Object detection, as its name suggests, is entirely self-detained and functions by flagging known items, not individuals. Therefore, people’s private information remains just that — private.

Object detection AI surveillance systems, however, can detect weapons, abandoned objects, and other possibly threatening items with high accuracy.

Upon detection, the AI system can then notify security professionals of their location in real-time. Real-time allows for nearly instant responses. In the recent Virginia Beach shooting, officers took nearly 10 minutes to locate the gunman after they entered the building, and by the time the officers had subdued the gunman, the attack had lasted about 40 minutes.

Personal privacy and public safety don’t have to be mutually exclusive and may not be a false choice between privacy and safety.

It’s time we stopped trying to overextend AI video surveillance to do the work of security professionals. Instead, let’s focus on technology that already works to provide them with real, actionable data that can help them do their jobs better. We can create a safer society without sacrificing civil liberties.
