Digital Image Watermarking using DWT and Encryption with RGB Pixel Shuffling and PWP Techniques

Images are the most common word for every individual. Almost every area deals with image processing. Especially in security and military applications image processing is used. One the major stem of image processing is image watermarking and image cryptography. This research involves both watermarking and cryptography. The wavelets are a big family in which symlett wavelets are used. This paper deals with watermarking as well as encryption which uses Discrete Wavelet Transform (DWT), RGB (RED, GREEN, BLUE) pixel shuffling and Parallel Whirlpool Algorithm (PWP) techniques. A color image is processed where RGB pixels which are shuffled according to the procedure which does not affect the intensity, while retrieving back the original information. Techniques like De-noising, segmentation, smoothening and sharpening used for pre-processing the image. The different variants of DWT are considered to obtain proper watermarking. Watermarking with cryptography is the unique concept for proper security. The results were promising to obtain perfect security
