ThiefTrap - An Anti-theft Framework for Android.

Smartphones store a plenitude of sensitive data. This data together with high values of smartphones make them an attractive target for physical theft. Clearly, the device owner would like to regain the device in such a case. Also, the information should be protected from illegitimate access. In this paper, we present the first anti-theft solution that effectively handles these issues. Our proposal is based on a novel concept of an anti-theft honeypot account that protects the owner's data while preventing a thief from resetting the device. Thus, a stolen device can be regained by the device owner with high probability, while information leakage to the thief is prevented. We implemented the proposed scheme and evaluated it through an empirical user study with 35 participants. In this study, the owner's data could be protected, recovered, and anti-theft functionality could be performed unnoticed from the thief in all cases.
