Abstract
Visual Cryptography is an image encryption technique used to hide the secure information in images. It allows the encryption of secret image into n number of shares and distributed into n number of participants. For example in (k, n) secret sharing problem the secret image can be visually recover by stacking together any k or more transparencies of the shares. But cannot reveal any secrete information by stacking less than k transparencies together. The Embedded EVCS is constructed by adding random shares of secret image into meaningful covering images. The proposed system will work with color images which is not possible with existing embedded EVCS approach. This approach will test the same algorithm for color images which will take the R, G, B values separately and add shares to it. It will improve the contrast of the recovered secret image and produce clear resultant image.
