COLOR EXTENDED OPTICAL CRYPTOGRAPHY USING RANDOM SHARES FOR VISUAL TRANSFERRING SCHEME

Abstract-The paper proposes a work on color extended optical cryptography using random shares, having ability of hiding of securing confidential data without mounting the pixels. optical cryptography scheme allows encoding of secret image into ‘n’ shares which are distributed to the participants for providing safety against hacker and sight, in this less than n cannot recover the secret image. previous method in the literature shows good result for black and white or gray level image, however they are not sufficient to applied to color image due to different color structure. some method for color optical cryptography are not satisfactory because they are expanding the image exponentially .and making the size of image double,in terms of meanigfull share with low visual quality. The new method overcome with the previous method and generates pleasent shares.
