Mohamed Shehab, Watermarking Relational Databases

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.
