摘要：Hiding the data in digital images has been area of interest in the digital image processing domain. Althoughso 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 practicalrequirements. This paper presents an approach where mosaic image generation has done by dividing thesecret image into fragments and transforming their respective color characteristics into correspondingblocks of the target image. Usage of the Pixel color transformations helps to yield the lossless recoveredimage based on the untransformed color space values. Generation of the key plays an important role torecover the data from the secret image in lossless manner. Finally the same approach can be performed onvideos also which helps to eliminate the flickering artifact to achieve the lossless data recovery in motionrelated videos. The experimental results shows good robust behavior against all incidental and accidentalattacks and compare to the conventional algorithms Performance evaluation has been increased in asignificant way
