Abstract: The secret sharing scheme plays a vital role in cryptography which allows to transmit the secret digital information (image, video, audio, handwritten notes etc.) over a communication channel. The Encoding is done in special way using Visual cryptographic schemes and decoding is carried out by the human sensory system without complexity. The secrets are encrypted into shares in these schemes, stacking these shares with minimal loss will disclose the secrets. These shares are presented in n number of transparencies. This paper provides an overview of various VC schemes of single secret and multi secret of grayscale and color secret images. Also, comparative analysis study on these schemes are presented, based on pel expansion, contrast, accuracy, capacity, security, type of share, number of shares, image format.
Keywords: Contrast, Multi secret VCS, Pixel Expansion, Single Secret VCS, Shares, Security.
