San Francisco based start-up “Handshift” has built devices that use cameras and cameras to collect data about your movements, rather than facial recognition technology that could ultimately lead to surveillance.

The software then feeds its findings into facial recognition software that can recognize users even when they don’t know they’re looking.

“So instead of just looking you in the eye, and you’re like, I’m actually the person, and I’m not just looking at a computer screen,” said Kevin Riddle, the CEO at Handshift.

Riddle says his company is using artificial intelligence methods to identify you based on what you’re typing on the keyboard.

“What we’re not doing is actually scanning the keyboard to see if we can identify it,” said Riddle.

Riddle said in just one week, he had developed an algorithm that could find and classify users based on what they were typing, not looking at keyboard.

“I think that’s the biggest thing we’ve been getting a lot of feedback on — if we can sort of make it better,” said Riddle.

The Handshift software is being used in San Francisco, and the San Francisco Police Department has had to use the software even more for undercover operations.
