This paper proposes a method for protecting data from unauthorized access with the use of both stenographic and cryptographic mechanisms. The system uses block pixel-value differencing (BPVD) and Advanced Encryption Standard (AES) for data protection. The original image is partitioned into 4 × 4 blocks and the data gets traversed in all the three directions and RGB channel. Based on the hiding capacity of each direction, the proposed method choose a color channel for embedding the encrypted data. AES method is used for encrypting the text data to be embedded. In this new hybrid method the concealing capacity of the image is improved as each direction obtain maximum data. As the data is encrypted, the security of the system is improved much. Using color images the concealing capacity of PVD method is identified and direction based analysis is provided in it.
