In this paper, a new technique for hiding the data of images has been proposed. This method uses 3-dimentional discrete cosine transformation scheme, along with 2-dimentional discrete cosine transformation. The method proposed in this paper hides two target images behind one cover image thereby increasing the data hiding capacity greatly. For the cause of(More)
Technique for hiding the data of images has been proposed in this paper. At the source, hidden (target image) is encoded within another image (cover image). Firstly, the cover image and the target image can be adjusted by resize function. Secondly, only the final encrypted image i.e. cover image and target image is sent over the network.
