Secure Image Transmission Technique Based On Mosaic Image and Pixel Color Transformation

Archana S. Jagtap | Prashant S. Malge

Abstract: Hiding the data in digital images has been area of interest in the digital image processing domain. Although so much work has been carried out in the literature to resolve the issues like increasing the data capacity, creating the secret image alike of target image but most of the works fails to meet the practical requirements. This paper presents an approach that can transform a secret image into a secret fragment-visible mosaic image of the same size that has the visual appearance of any freely selected target image without need of a database. Where, this mosaic image generation has done by dividing the secret image into fragments and transforming their respective color characteristics into corresponding blocks of the target image. Usage of the Pixel color transformations helps to yield the lossless recovered image based on the untransformed color space values. Generation of the key plays an important role to recover the data from the secret image in lossless manner. So, only with the key, a person can recover the secret image nearly lossless, from the mosaic image. Good experimental results show the feasibility of the proposed method.
