A Survey on Reversible Watermarking Schemes for Relational Data

Abstract

Abstract-"In recent years, ease of the Internet has boosted use of information systems comprising relational data. Relational Databases have been extensively used for information extraction within collaborative environments. In this context, protecting ownership rights and data integrity along with tackling data tampering have become the major issue. Watermarking approaches have been introduced to overcome these issues. It is important for a watermarking method to outperform for maintaining data quality of relational data while recovering data with watermark. Here, reversible watermarking approaches for relational database are compared and studied. These methods ensures data quality along with data recovery in presence of malicious attacks (insertion, deletion and alteration).
