Abstract
Digital watermarking now-a-days become more and more important due to tremendous availability of digital data on internet. The use of databases in various internet base applications has increased tremendously and theft of the data from database is a main concern for the database owners. Therefore, it is crucial to protect the piracy of the database. Most important technique in watermarking is its secret key and insertion location. In this paper, a new relational database watermarking method for non-numeric data is proposed based on nonnumeric attributes. A mark is computed based on the hill cipher technique. The position where mark is to be inserted is taken by the user. Our method is effective as it is robust and secure against different forms of malicious attacks.
