Study on Watermarking Relational Databases

The use of digital watermarking to secure the content of database systems is a new research direction in information security. Until now, the majority of the work has been based on image, video and audio. However, because of the growing use of relational database systems, database watermarking has become a research subject. Which addresses the legal issue of database system copyright protection. In this paper, we have focused on the review of four relational database watermarking techniques proposed by researchers [R. Agarwal & Jerry Kiernan, ZHU Qin, Brijesh B. Mehta, A. Al-Haj and Ali Hamadou]. The security of relational databases has been a great concern since the expanded use of these data over the Internet. Digital watermarking for relational databases emerged as a candidate solution to provide copyright protection, tamper detection, traitor tracing and maintaining integrity of relational data.
