A Fragile Zero Watermarking Scheme to Detect and Characterize Malicious Modifications in Database Relations

The Scientific World Journal, 2013
We put forward a fragile zero watermarking scheme to detect and characterize malicious modifications made to a database relation. Most of the existing watermarking schemes for relational databases introduce intentional errors or permanent distortions as ...
