Abstract: In today’s digital world, privacy concerns for data over the internet have increased. In many communications we transmit digital images and these images contain confidential information. Making is vulnerable towards unauthorized personals attacking the image and leaking our information which demands higher privacy. So, there are a number of methods available for achieving this privacy, one of them being Random key Steganography. This make use of Mosaic image creation which has two distinct techniques, DWT (Discrete wavelet Transform) and DCT (Discrete Cosine Transform). The target image is randomly selected into blocks to uses of this image for hiding secret image. Target image and Secret image is divided into 2×2 blocks called image tile respectively. A secret image hiding scheme is proposed with new security features. This scheme utilizes the mosaic images, which is created from the secret and target images. A Combined (mosaic) image or watermark image is similar to source image. The secret image blocks are hidden in the target image by performing appropriate random pattern blocks.
