(Let’s see, there’s malware, a thief guessing my lame password, or it could even be someone looking over my shoulder.) Now, according to researchers at Syracuse University, using a smartphone in public at all might be a bad idea because of something called spatio-temporal dynamics.
Spatio-temporal dynamics is a type of artificial intelligence that involves calculating the distance and relationship of objects. In an experiment conducted last year, the Syracuse researchers discovered thieves could use spatio-temporal dynamics to figure out smartphone passwords. Here’s how it’s done: the hacker videotapes someone using a phone, even if all he’s able to get is the back of the device and the movements of the user’s hands as they type. The hacker then applies an algorithm to the video footage that…
