More than 10,000 video cameras watch over public schools in Broward County, Florida, where the Parkland shooting took place last year, Kaveh writes.
- Most are normal cameras, recording footage to be watched later. But about 150 feeds, from the "highest risk" of about 50 high schools and alternative schools, are instead scrutinized by unblinking artificial intelligence.
- The AI system, which cost hundreds of thousands of dollars, can follow a student's movements over time, even if they appear on different cameras.
- And it can detect "unusual" behavior, like someone running in a location where most walk, or appearing someplace that's usually empty at that time.
What's happening: Until now, the vast majority of information collected about us has remained untouched — there was just too much to make sense of it all. But AI allows data that might once have gone unnoticed to now be detected, analyzed and logged in real time.
It's already started supercharging surveillance at work, in schools and in cities:
The big picture: Humans have monitored each other as long as we've lived in communities — to punish free riders and troublemakers.
- But now, cheap, powerful machines are taking the place of human watchers, disrupting a long-held social contract.
- Unlike in China, where high-tech surveillance is a tool of fear and control, systems in the West are not centralized for now, curbing the scope of data gathering.
- And tech companies like Facebook and Google have perfected online versions of automated surveillance for profit, in the form of products we can no longer live without.
Details: Software can identify and track faces, skin color, clothing, tattoos, walking gait and various other physical attributes and behaviors. But it's been plagued with bias and inaccuracy problems that primarily harm people of color.
- From facial expressions and body movements, AI can extrapolate emotions like happiness and anger — a process built on shaky scientific evidence.
The impact: This quiet shift from passive watching to active surveillance is chipping away at our ability to remain anonymous in physical and virtual spaces.
- Blending into the crowd is no longer an option if every face in that crowd is captured, compared against a driver's license photo and logged.
- Constant AI surveillance threatens to erode the all-important presumption of innocence, says Clare Garvie, a privacy expert at Georgetown Law.
