Abstract

Proving ownership rights on outsourced relational databases is a crucial
issue in today internet-based application environment and in many content
distribution applications. In this talk, we will present mechanisms for
proof of ownership based on the secure embedding of a robust imperceptible
watermark in relational data. We will discuss the available watermark
embedding and decoding techniques. Furthermore, we will provide a
comparison between these techniques based on several dimensions such as
applicability, efficiency, and security.
