Secure digital image sharing using diverse image media

Traditional visual secret sharing (VSS) schemes share secret images in form of shares that may be printed on transparencies or stored in any digital form. The shares used in those methods would be noiselike or meaningful which will increase transmission risk. This effects both the secret and the participants. In order to solve this problems a secret sharing method which uses another images to transmit the secret and a method which increases the security is proposed here. The proposed scheme can share one digital secret image using n − 1 selected shares and one share which is noise share and also provides more security. The noise-like share is generated based on the natural shares and the secret image. The natural shares are not altered and decreases the transmission risk. Also proposes a better secure way to hide the noiselike share to reduce the transmission risk problem for the share. Experimental results shows that the proposed approach is an excellent solution for solving the transmission risk problem for the VSS schemes.
