摘要：A secure image transmission technique via mosaic image using HSV converted target image andreversible data hiding method is a new type of image protection method. It can transmit a secret image by converting itinto secret fragment mosaic image and hidden inside a target image with the help of a reversible data hiding technique.Mosaic image are generated by converting secret image color to those of target image color and then diving it intosmall fragments. Color transformation is done based on a skillful method so that original image can be losslesslyrecovered. Inoder to reduce recovered image distortion and increase its security, before color transformation, targetimage are converted to its HSV color model. Underflow and overflow problem are solved by recording pixel value inuntransformed color space. To increase security, mosaic image along with encrypted information that is required torecover original image are hidden inside target image by using a reversible data hiding technique
