Watermarking is the process of embedding new data into image, audio or video. Digital Watermarking technique is used to hide a secret or personal message to protect a products copyright or to demonstrate data integrity. To provide double protection, after the watermarking process, the watermarked image tends to go through an encryption process using CHAKRA – symmetry key encryption algorithm which encrypts the data with the concepts of Cartesian coordinate geometry and circle generation. In this paper, we perform watermarking on different types of images like BMP, JPEG etc.., and the input image is pre-processed and converted into JPEG-LS format which contains enhanced quality.

JPEG Steganography, uniform embedding, distortion function design.
