One of the major issues concerning all the web application is security of data and proving authority of database. In this paper we present a robust technique of embedding watermark in a relational database with non numeric attributes. In the proposed technique, an attribute is selected using a pseudorandom generator and the watermark is embedded in it. The vowel to be embedded is selected by calling a Key_Extraction ( ) on primary attribute of the same tuple. Our technique develops a secret key of embedded vowels which is provided to the user. The technique is robust against different malicious attacks and is blind and imperceptible, as proved by our analysis.
