Robust Watermarking For Relational Database
Watermark describes information that can be used to prove the ownership of data such as the owner, origin or recipient of the content. Watermarking is the piece of data securely embedded and this is said to be imperceptible. The authors implemented a proof of concept of their watermarking technique and showed by experimental that their technique is resilient to tuple deletion, alteration, and insertion attacks. It includes the feature of detectability, i.e. the original data can be retrieved only with the help of the key value.
