Blind Recognition of Touched Keys: Attack and Countermeasures
CoRR, 2014 In this paper, we introduce a novel computer vision based attack that discloses inputs on a touch enabled device, while the attacker cannot see any text or popups from a video of the victim tapping on the touch screen. In the attack, we use the optical flow algorithm to identify touching frames where the finger touches the screen surface.

Mutual features for pattern classification [PDF]
, 2009 The mean of a data set is one trivial representation of data from one class. This thesis discusses mutual interdependence analysis (MIA) that is successfully used to extract moreinvolved representations, or “mutual features”, accounting for samples in ...

Speaker Recognition Improvement Using Blind Inversion Of Distortions
CoRR, 2004 In this paper we propose the inversion of nonlinear distortions in order to improve the recognition rates of a speaker recognizer system. We study the effect of saturations on the test signals, trying to take into account real situations where the training material has been recorded in a controlled situation but the testing signals present some ...
