Discrete Z Transformation based Copyright Protection on Digital Image Using Genetic Algorithm

Prashant C. Harne | Rajesh K. Nigam

Abstract: Today, due to the outburst of exchanging digital images worldwide on the internet and the extensive use of digital media it is necessary to show keen interest in multimedia copyright protection. The aim is to propose a secure algorithm for protecting digital image as copyright using digital watermarking approach. Now days concept of digital watermarking scheme has attracted research scholars in the emergent areas of digital watermarking security and digital image authentication as a copyright protection. Digital Watermarking is an effectual solution for protecting intellectual property of image, audio and video data. The watermark should be produced in such a way that it is independently and identically distributed. The robustness and fidelity play predominant role during the process of digital watermarking. Robustness is nothing but potency of the watermarking against various image processing attacks and fidelity concern for the original quality of image after embedding the watermark. So in order to gain these features the concept of Discrete Z Transform and Genetic Algorithm is applied.
