摘要：Today’s world with the growth of digital media, it is becoming more prevalent to finda method toprotect the security of that media. An effective method for securelytransmitting images is found in the field of VisualCryptography (VC). Visualcryptography uses the characteristics of human vision to decrypt encrypted images.Sharingof secret information via emails is not that much secure as the information ordata can be hacked easily by the thirdparty.In this current work we have proposedVisual Cryptographic Scheme for color images where the divided sharesareenveloped in other images using stamping. The shares are generated using RandomNumber. Visual CryptographySchemes (VCS) is a process of encrypting the imagewhich hide the secret information present in images. In simplevisual cryptographictechnique encryption of secret image is done by splitting the image into n number ofshares and theStamping process is performed by overlapping k number of shares. Itmay helps to hide secret image. The decryptionprocess of simple visual cryptographicsystem can be performed by a human eye so there is a possibility of securityissueswhile using cryptography for sharing information and to solve this problem we areusing OTP process. Earlierstatic ID and Password are used which is vulnerableagainst eavesdropping and replay attack. To overcome this problemOne TimePassword technique is used which give different password each time. Previousmethods faced some securityissues like pixel expansion and noise troubleshoot theproposed system add more security to generated transparencies byapplying anenvelope to each shares by using stamping algorithm.
