Cheating Identification and Prevention in Secret Sharing Scheme using Digital Watermarking

Visual cryptography (VC) is numerous applications, including visual authentication and identification, steganography, image encryption and digital watermarking. A new cryptographic scheme proposed for securing color image based on visual cryptography scheme. the watermark method is an excellent technique to protect the original information of a digital image. In exiting system there is work on binary images. we are introduced new system which are using the sharing schemes for dividing color image and apply digital watermarking for security of shares .We are dividing our system into three main phases creation of shares, distribution of shares and construction of secret. since we are identify and prevent cheater participant and block the cheater participant .In this paper, we and show that it is not cheating immune. We also outline an improvement that helps to overcome the problem.
