Secure Data Deletion

This book is the first to develop a systematized approach for the comparison and evaluation of secure deletion solutions. The book focuses on novel secure deletion solutions targeting specific real-world environments where secure deletion is problematic: mobile storage and remote storage. The author surveys related work, organizes existing solutions in terms of their interfaces, presents a taxonomy of adversaries differing in their capabilities, and then builds a system and adversarial model based on the survey of related work.

The book is useful for both academics, researchers and graduate students, and for practitioners who may integrate its results into deployed systems.
