Brazilian Police To Use Facial Recognition Glasses To Spot Criminals... But Does It Even Work?

from the ah,-details dept

Apparently Brazilian police are investing in a system of Robocop-style glasses that will allow the police to scan crowds of people with the glasses, and have a small camera spot known criminals. That's the theory. What's surprising to me is that no one in the article seems to question whether or not this technology actually works. We've been hearing a lot about facial recognition technology over the years, especially for situations like this. Yet, every time we hear about tests of public camera systems with facial recognition, it later turns out that they're close to useless. Multiple places that have installed such cameras later took them down after they failed to (legitimately) spot any criminals. Now, many of those stories are a few years old, and the technology has improved... but until there's actual evidence that a system like this can actually work (especially in a miniaturized glasses setup), it seems that skepticism should rule the day.

    I don't know if its the same company, but it will certainly be treated the same. That is, the glasses will be initially used to catch known criminals. It will certainly fail, but the false positives will still be searched. Some of those false positives will be found guilty of some crime (I don't know what Brazil's drug laws are, but drug laws are what would be handy in the US), and thus the glasses will be hailed as a success.

    That's what the TSA does all the time. Sure, they haven't caught a terrorist yet (nor could they) but they've found illegal stuff (mostly drugs) so they claim they are completely successful.
