摘要：The rapid development of the Internet and related technologies has allowed for the tremendous ability toaccess and redistribute digital multi media contents. In such a context, protecting the ownership and controlling thecopies of digital data have become very important. Watermarking technique is used to impose ownership rights overshared relational data and for providing a means for tackling data tampering. When ownership rights are imposed usingwatermarking, the underlying data undergoes certain modifications; as a result of which, the data quality getscompromised. The main aim is to maintain the ownership of Relational Database and also minimizing distortion in thewatermarked content. Therefore, reversible watermarking is required that ensures watermark encoding and decoding byaccounting for the role of all the features in knowledge discovery and original data recovery.
