DIGITAL IMAGE SHARING BY DIVERSE IMAGE MEDIA USING NVSS TECHNIQUE

Electronics and Telecommunication Engineering

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 shares contains Secret Images. To address this problem, we proposed 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. This Process involved sharing a secret image over arbitrary selected natural images (called natural shares) and one noise-like share. The natural shares can be photos or hand-painted pictures in digital form or in printed form. The noise-like share is generated based on these natural shares and the secret image. The unaltered natural shares are diverse, thus greatly reducing the transmission risk problem. We also propose possible ways to hide the noise like share to reduce the transmission risk problem for the share. The possible ways to hide the generated share are also discussed. The proposed NVSS scheme not only has a high level of user friendliness and manageability, but also reduces transmission risk and enhances the security of participants and shares. We successfully introduce hand-printed images for images-haring schemes. The proposed Algorithms are applicable to digital and printed media. This study proposes a useful concept and method for using unaltered images as shares in a VSS scheme. We develop a method to store the noise share as the QR code. Experimental results indicate that the proposed approach is an excellent solution for solving the transmission risk problem for the VSS schemes.
