Pooja Sharma, Ashutosh Sharma · 2018 2nd International Conference on Inventive Systems and Control (ICISC) · 2018
In this abstract of the porpose paper, we proposed robust method for the digital watermarking or the steganography on Red part with Discrete Cosine Transform (DCT) algorithm with discrete wavelet transform which is (DWT) algorithm. In this scheme, we used 2 images primary one is wrap image and secondly is mystery photo. For the progressed guard, we worked on the Red Component. We labored on 2 mechanisms-first of all is 3-DWT and the second is DCT. Inside this proposed, we implemented 3-DWT and DCT on peak of RGB (red, green and blue) factors. The experimental outcome based on the psnr value in addition to its reach upto the 56%.
