Abstract

Digital Watermarking, in the traditional sense is the technique of embedding un-detectable (un-perceivable) hidden information into multimedia objects (i.e. images, audio, video, text) mainly to protect the data from unauthorized duplication and distribution by enabling provable ownership over the content. Recent research of the authors introduces the issue of digital watermarking for generic number sets. In the present paper we expand on this foundation and introduce a solution for relational database content security through watermarking. To the best of our knowledge there is no research on this issue. Our solution addresses a series of important attacks, such as data re-sorting, subset selection (up to 30% and above data loss tolerance), linear data changes. Finally we present dbwm.*, a proof-of-concept implementation of our algorithm and its application on real life data, namely in watermarking data from the outsourced Wal-Mart sales database of the years 1999-2000.
