SDS Technique For Encrypting Image Secretly
Maintaining the secrecy and confidentiality of images is a vibrant area of research and for this two different
approaches are being followed. The first being encrypting the images through encryption algorithms using key and the other
approach involves dividing the images into random shares to maintain the images secrecy. Unfortunately, heavy computation
cost and key management limit the employment of the first approach and the poor quality of the recovered image form the
random shares limit the applications of the second approach. In this paper, we propose a novel approach without the use of
encryption keys. The approach employs Sieving, Division and Shuffling to generate random shares that with minimal
computation, the original secret image can be recovered from the random shares without any loss of image quality.
