Abstract: Database watermarking has gained a keen interest of researchers since the coin was tossed by Agarwal. Since then many approaches have been adopted to protect the copyright of relational databases. The concept was proposed after getting inspiration from watermarking digital assets. Watermarking has been helpful in integrity check of relational databases as well and so far techniques have been proposed for integrity check and temper detection. In the paper, an algorithm is proposed called Self-Constructing Fragile Watermark (SCFW) for integrity check of relational databases. Proposed scheme consists of highly dependent watermark information. Any tempering or leakage is reflected over the watermark information. Experiments show that proposed technique is affective against temper detection. Even a little amount of tempering is reflected efficiently because of the self-replicating nature of proposed algorithm.
