An Enhanced Technique for Secure Image Transmission Via Visual Cryptography and Secret Fragment Visible Mosaic Images
Rucha R. Raut, Prof. Komal B. Bijwe
Abstract: In this paper a new type of computer art image called secret fragment visible mosaic image is proposed which transforms automatically a given large-volume secret image into a so called secret fragment visible mosaic image. The mosaic image, which looks similar to an arbitrarily selected target image and may be used as a camouage of the secret image, is yielded by dividing the secret image into fragments. The information required for recovering the secret image is embedded into the created mosaic image by a lossless data hiding scheme using a key. Shamir secret sharing algorithm plays an important role in this project. Shamir-s secret sharing is an algorithm that divides a secret into shares. For encryption of secret image Shamir Encryption method is used and for decryption process Shamir Decryption algorithm is used. Secret can be recovered by combining certain numbers of shares. An additional measure to enhance the embedded data security is also proposed.
