Image Based Relational Database Watermarking: A Survey
Journal Title: IOSR Journals (IOSR Journal of Computer Engineering) - Year 2015, Vol 17, Issue 3
Abstract
Abstract: In past few years relational databases watermarking has emerged a great topic for research becauseof increase in use of relational databases. The basic need for relational database watermarking is to preventdata from illegal access by providing copyright protection, tamper detection and maintaining integrity. To servethis purpose many database watermarking techniques have been addressed with different algorithm and covertype. With the use of watermarking unauthorized duplication and distribution can be detected. Thewatermarking scheme should be able to meet some important challenges: 1). The scheme should be capableenough to bear attacks so that the watermark doesn’t get corrupted 2). The technique should be data preservingi.e. the error introduced into database as watermark information should not affect the value of data. The basicpurpose of this paper is to review and analyse some existing image based database watermarking techniques.
