Modern smartphones are equipped with a plethora of sensors that enable a wide range of interactions, but some of these sensors can be employed as a side channel to surreptitiously learn about user input. In this paper, the authors show that the accelerometer sensor can also be employed as a high-bandwidth side channel; particularly, we demonstrate how to use the accelerometer sensor to learn user tap and gesture-based input as required to unlock smartphones using a PIN/password or Android's graphical password pattern.

Rights Amplification in Master-Keyed Mechanical Locks - This paper describes a relatively unknown procedure for obtaining a master key if given access to a tumbler based master keyed lock and any low level key in the system. No special skill or equipment beyond a small number of blank keys and a file is needed, and the attacker does not need to engage in any suspicious behavior at the locks location. Countermeasures are described with provide limited protection under certain circumstances.
