Abstract

"In this paper we have proposed a novel scheme for separable reversible data hiding using matrix addition approach for color images. In this proposed paper we have discussed that a content owner encrypts the original uncompressed image using an encryption key.Then, data hider which will provide a data hiding key and also embed the additional data. With an encrypted image containing additional data, due to the security concern at receiver side original image and hidden data is recovered separately by providing encryption and data hiding key separately without knowing the contents of original image. If the receiver has the encryption key, he can decrypt the received data to obtain an image similar to the original one, but cannot extract the additional data. If the receiver has both the data-hiding key and the encryption key, he can extract the additional data and recover the original content without any error when the amount of additional data is relatively large. In the propose new idea we are suggesting that BPCS maybe the effective one as it Bit Plane Complexity Segmentation system in which we can embed more data in given image. "
