“…The encoder compresses the source and encrypts a bit stream using a secret key before transmitting over a public channel, the decoder decrypts the received bit stream and then decompresses the result [10]. A lossless data hiding scheme which uses an edge detector to locate plain areas for data embedding in digital images is discussed [11]. A new image encryption method is presented by the authors by selecting specific higher frequencies of DCT coefficients as characteristic values for encryption and then the encrypted blocks are shuffled according to pseudorandom bit sequence [12].…”

Image Encryption has a significant role in the field of cryptography. A new encryption scheme is introduced to protect an image from unauthorized access, in this scheme two separate keys are used for image encryption and data hiding with high degree of security. The content owner encrypts the original uncompressed image using an encryption key. The least significant bits (LSBs) of the encrypted image are compressed using a data hiding key to create space to embed an additional data. Run -Length Coding (RLC) and Haar Wavelet compression technique is employed to reduce the image size and facilitate faster transmission. Encrypted and decrypted sections, the quality of image retrieval and data extraction are achieved from RLC with their respective keys. In this scheme user can extract an image, data and both image and data based on the keys used.

“…Mehdi Fallahpour, DavidMegias, [2] In this letter a lossless data hiding scheme for digital images can be achieved by edge detector to locate plain areas for embedding. The proposed method takes advantage in image coding.In the suggested scheme, prediction errors and edge values are first computed and then, excluding the edge pixels.…”

Abstract-In this paper, Reversible data hiding method proposes a completely unique reversible information concealment technique with an modifying set in capability by increasing the general whole number transformation (GIT). The data is modify the scum bag algorithmic program to an additional generalized type, andconsequently we propose AN adjusted embedding algorithmic program. Once concealment information into the starting image, characteristics of the increased scum bag is identified in first step within the content of every block. Close by a multi-level location map, a higher modifying potency of information is achieved. On the coding system, the starting image can be recovered once extracting the secret message. The above technique shows that based on the RDH.
