In this paper, we arise this concern by presenting an automatic attack against modern touchscreen keyboards. We demonstrate the attack against the Apple iPhone-2010's most popular touchscreen device-although it can be adapted to other devices (eg, Android) that employ similar key-magnifying keyboards.

A set of concentric circles (C2Tag) is well suited to cope with the camera tracking problem: a C2Tag is very discriminatory in pictures, its detection is also possible in occluded cases and it can be identified by mean of a possible coding. In addition, its geometry is closely related to the euclidian structure of the support plane.

Binocular information about the structure of a scene is contained in the relative positions of corresponding points in the two views. If the eyes rotate, in order to fixate a different target, then the disparity at a given image location is likely to change. Quite different disparities can be produced at the same location, as the eyes move from one fixation-point to the next. The pointwise variability of the disparity map is problematic for biological visual systems, in which stereopsis is based on simple, short-range mechanisms.

Even if the victim is well protected from digital attacks, spying may be a viable option. In addition, the pervasiveness of mobile devices increases an attacker's opportunities to observe the victims while they are accessing or entering sensitive information.
