Data protection: Combining fragmentation, encryption, and dispersion

Abstract

In this paper, we first present a general description of what is a fragmentation system including a number of high level requirements. Then, we focus on fragmentation of two kinds of data. First, a bitmap image is split in two parts a public one and a private one. We describe two processes and address the question of performance. Then, we survey works on fragmentation of text: in a brute force manner then considering data stored in a structured database.
