摘要：Information hiding was initially done by techniques like Steganography, Digital Watermarking, etc. Anew type of digital art called the Secret Fragment Visible Mosaic Image has been discussed in this paper forinformation hiding. The information that is to be sent secretly is sent as an image, embedding it into another imagecalled the target image. Small fragments of both the target image and the secret image are composed and embedded intoeach other resulting in the formation of a mosaic image. To create mosaic image, the target and the secret image arefragmented into blocks of equal size. The pixel color values of all the pixel in a block is computed by the 1-DHistogram Transformation Technique and saved. By using the greedy algorithm, the similar image for the secret imageis found out and a secret key is generated using Randomized algorithm. The tiles are embedded into the blocks byLossless LSB Replacement Algorithm and the mosaic image is generated. The recovery is done by the secret recoverysequence.
