Abstract: Visual secret sharing (VSS) systems hide hidden images in shares that are also published on clarity or decrypted and saved in digital form. The shares can seem as noise-like pixels or as meaningful images, but this will raise suspicion and increase the risk of interception during transmission. As a result, VSS schemes face a transmission danger problem for both the secret and the individuals involved in the VSS system. To solve this issue, we presented a new palette-grounded steganography technique that uses a texture with LSB, as well as a natural-image-grounded VSS scheme (NVSS scheme) that shares secret images via colored carrier media to hide the secret and the actors during the transmission phase. To conceal secret messages, we convert the texture conflation process into steganography. Rather than using a being cover image to conceal dispatches, our algorithm conceals the source texture image and embeds hidden dispatches during the printing process. Prints or hand-painted filmland in digital or published form can be used for the natural shares. We also propose possible methods for concealing the secret in order to reduce the transmission threat problem for the share. The experimental results show that the proposed approach is an excellent solution to the transmission threat problem for VSS schemes.
