| Summary: | Digital watermarking has been in multimedia data use over the past years. Recently it has become applicable in
relational database system not only to secure copyright ownership but also to ensure data contents integrity. Further, it is
used in locating tampered and modified places. However, the watermarkingrelational database has its own requirements,
challenges, attacks and limitations. This paper, surveys recent database watermarking techniques focusing on the
importance of watermarking relational database, the difference between watermarking relational database and multimedia
objects, the issues in watermarking relational database, type of attacks on watermarked database, classifications, distortion
introduced and the embedded information. The comparative study shows that watermarking relational database can be an
effective tool for copyright protection, tampered detection, and hacker tracing while maintaining the integrity of data
contents. In addition, this study explores the current issues in watermarking relational database as well as the significant
differences between watermarking multimedia data and relational database contents. Finally, it provides a classification of
database watermarking techniques according to the way of selecting the candidate key attributes and tuples, distortion
introduced and decoding methods used. |
