Secured Lossless Share Watermarking

Abstract

Security has gained a lot of importance as information technology is widely used. The main issue in visual cryptography is quality of reconstructed image. This problem is overcome by using “Secured Lossless share Watermarking ”. In this method the quality of reconstructed image is higher and the security of share is high compare with conventional visual cryptographic scheme. The secret image is converted into. Each share is embedded to different carrier images. Invisible watermarking method is used for embedding carrier image and shares. For security, the invisible watermarked shares are then encrypted, AES modified encryption method is used. The encrypted shares are send to other participants. At the receiver end receiving the shares and decrypt the shares, then combining these shares together reveal the secret. The quality of rejoined shares and original secret shares are almost same.
