Encrypting Digital Images and Using Diverse Image Media for Sharing Digital Images

Visual Secret Sharing Schemes hide a Secret image in shares that appear noise like picture or noiseless picture. VSS schemes suffer from a transmission risk problem while sharing contains Secret Images because it will awake suspicion and increase interception risk during transmission of the shares. The proposed system consists of a natural-image-based VSS scheme (NVSS scheme) that shares secret images via various carrier media to protect the secret and the participants during the transmission phase. For this process the share contain arbitrary number of natural images and one noise like share. The natural shares can be photos or painted pictures in digital form or in printed form. The printed form images convert to digital form for the digital processing and these printed images can be send via postal or any other method. The noise-like share is initiated based on these natural shares and the secret image. The unaltered natural shares are diverse and safe, thus greatly reducing the transmission risk problem. The unaltered content of the natural images cannot easily detect by the suspicious.
