In this paper, the authors propose 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 paper shows good result for black and white or gray level image, however they are not sufficient to apply to color image due to different color structure.
