Read the section "limitations". Only works on 10 users right now, must be trained for the pattern "per user", phone must be sitting on stable surface, gesture must be performed as close to "the same" every time. This is just clickbait and "please fund our research" IMO.
- pslam 10y agoWhat did you expect — a turn-key solution for sale? They claim no such thing. This is great research. They've demonstrated that it is in fact possible to obtain a passcode at a distance, at least in contrived conditions. The fact it's possible whatsoever is a significant result. Even without being able to obtain the exact passcode, this would yield the ability to guess a passcode in much better time than just random selection.
- program_whiz 10y agoOk I think my issue with this is that its akin to saying: Given the same users, in the same position, with the same hardware, performing the same gestures, we discovered the signals are consistent enough that a NNet can figure out a pattern. However, if the users, the hardware, the wifi router, the positions, the orientations, the conditions, or the gestures used change, you would need to retrain your NNet for that situation. After working on a couple of "ambitious" projects that tried to use wifi or bluetooth signals to mine data, it turns out its not super reliable in real-world situations.
