Digital watermarking using spatial domain and triple DES

In today's era due to the open environment of internet use, a new set of problems are arising in context of copyright protection, security and unauthorized distribution of private images. This paper proposes the problem of fragile & semi fragile digital watermarking for the robustness & authentication of image. The aim is to combine both digital watermarking & cryptography together in order to embed the secret information to gain a high level of privacy & efficiency. TDES (Triple DES) encrypted watermark with a secret key bundle makes it very difficult for the invader to make changes or remove the encrypted image from the spatial domain of the cover image. The proposed schemes were implemented on MATLAB. The experimental result shows that the proposed schemes have optimal performance under various noises. These schemes have many possible applications like data integrity & authentication as well as content & copyright protection.
