Secret Fragment Mosaic Images: A Secure Method for Image Transmission

Shabana Vathelil Subair ^[2] | Timna P Elizabeth

Abstract: Images from various sources are often used and are transmitted through the internet for various purposes, such as confidential enterprise archives, document storage systems, medical imaging systems, and military image databases. These images may contain secret or confidential information since it should be protected from leakage during transmissions. An approach for secure image transmission is needed, which is to transform a secret image into a meaningful Secret Fragment Mosaic image with size almost same and looking similar to the preselected target image. The mosaic image is the outcome of arranging of the block fragments of a secret image in a way so as to disguise the other image called the target image. The mosaic image, which looks similar to a randomly selected target image, which is used for hiding of the secret image by color transforming their characteristics similar to the blocks of the target image. Such technique is necessary so for the lossless recovery of the transmitted secret image. The appropriate information is embedded into the mosaic image for the recovery of the transmitted secret image.

Keywords: Color transformation, data hiding, encryption of image, mosaic image, secure transmission of image
