RKO Technique for Color Visual Cryptography
Journal Title: IOSR Journals (IOSR Journal of Computer Engineering) - Year 2014, Vol 16, Issue 2
Abstract
Abstract : To maintain the secrecy and confidentiality of images two different approaches are being followed, Image Encryption and Visual Cryptography. The former being encrypting the images through encryption algorithms using keys, and the later approach involves dividing the image into random shares without the use of keys. Unfortunately heavy computation cost and key management limit the employment of the first approach and the poor quality of the recovered image from the random shares limit the applications of the second approach. In this paper we propose a novel approach with the use of random share and key share. The approach employs generating two shares of the original image. One random share and the other key share. The original secret image can be recovered from the two shares simply by Xoring the two shares without any loss of image quality.
