Robust Watermarking of Relational Databases Based on Extension of Quantization Index Modulation to Circular Histograms
International Journal of Engineering Technology
In the internet and cloud computing paradigms the use of digital data is increasing excessively, where such kind of data is stored in various digital formats and also in related nature as a relational data. Watermarking methods has been proposed for multimedia, digital documents, software and, more recently, for databases. Two categories, depending on application, distinguish watermarks: fragile watermarks for tamper detection and robust watermarks for ownership verification.In this paper, afatcat:emvepz3lobaprovzbnkyvrarqm
