An efficient image watermarking protocol based on composite image repudiation

“Reversible picture information concealing” (RIDH) is an extraordinary class of data disguising technique, which guarantees perfect era of the spread picture upon the extraction of the implanted message. In this paper, we propose a secured and the encrypted information utilizing a Reversible Image Data Hiding plan by means of key modulation. A Public key modulation system is utilized to accomplish data embedding. The advantage of this scheme is that there is no need to have a secret encryption key. An intense two-class Support Vector Machine (SVM) classifier which is assigned at the decoder side for various encoded and non-encrypted images. Henceforth, the original message and they embedded signal are decoded together. Successful experimental results have been dealt in detail to validate this scheme.
