The use of relational databases is growing rapidly over the internet and also in many applications worldwide and so it faces various issues like ownership right issues, tampering issues and many more. In this paper, the authors present a technique which can eradicate these issues using the SHA512 signature generation technique in which, they embed a watermark in the tuples of the database without changing the original data. That is by adding an extra column of signature bit to the database. This technique is resilient to all sorts of attacks on the databases which include deletion attack, alteration attack, and insertion attack too.
