This chapter presents our research into user-level secure deletion for flash memory, with a concrete example of an Android-based mobile phone. We show that these systems provide no timely data deletion, and that the time data remains increases with the storage medium’s size. We propose two user-level solutions that achieve secure deletion as well as a hybrid of them, which guarantees periodic, prompt secure data deletion regardless of the storage medium’s size. We also develop a model of the writing behaviour on a mobile device that we use to quantify our solution’s performance.
