As more and more databases are published on the internet nowadays, it is increasingly important to maintain the security of published databases. In this paper, we propose a distortion-free scheme for embedding and verifying integrity information for relational databases. The proposed scheme does not require any additional storage to store the integrity verification information, nor does it introduce any distortion to the original data. Meanwhile, the tampered area can be localized precisely at a block level. Experimental results indicate that our scheme has adequate performance to allow for its use in real world applications.
