Latest Patents

Radu Sion holds a patent for a "Method and system for rights assessment over digital data through watermarking." This system provides resilient watermarking of digital data, including numeric and categorical relational data. The method is based on a framework that preserves the higher-level semantics of the original data. It also allows user-level run-time control over the properties to be preserved and the degree of change introduced. The system is designed to withstand various attacks, such as subset selection, addition, alteration, and attribute remapping. For numeric relational data, approximately 40-45% of the embedded watermark may survive about 45-50% of original data loss. In contrast, for categorical relational data, the watermark may endure approximately 80% of original data loss with only about 25% degradation.
