Sensors detect the smallest movements
When small risks add up
The researchers are aware of the fact that the vulnerability they discovered is still small: an attacker would have to bring malicious code to his victim's mobile phone and then make him enter his PIN. And then some criminologist in Asia or the US would have the PIN code to unlock a mobile phone that he would hardly get in the fingers - well? Unfortunately the procedure, which the British call "TouchSignature" call, is extremely expandable. It also allows you to record passwords, referral TANs, and the like with a little more training data, and can check out the user's behavior: does he write a lot or read more? Together with other data, an even more accurate personality profile can be compiled than before. "It's like a puzzle game," says Siamak Shahandashti, One of the authors of the study: "The more puzzle pieces you have, the clearer the picture". Another aspect is a different aspect: smartphones and other intelligent devices contain a lot of sensors that their owners often do not know about. The data collecting the sensors work for us, right? But only until they are abused.
