Data hiding is the process of hidden embedding data into data sources such as audio, video, or image signals without changing the perceptual quality. The most common techniques in data hiding is the use of least significant bit and the use of redundancy in the cover image by performing lossless compression. The encryption is a general method for providing privacy protection such as confidentiality, integrity and authentication of data. The hiding of data ideas for encrypted images is made of encryption of image, embedding of data and extraction of data. In the encryption phase, initially the images are encrypted with the encryption key associated with data to be embedded on that encrypted image with data hiding key. In the decryption phase, the embedded image (associate with data) is extracted and decrypted with encryption key and encrypted data is extracted and decryption is made using data hiding key. Though, in both encryption and decryption process same encryption key and data hiding key is used. The objective of the work is to provide an efficient data hiding technique and Image Encryption in which the data and the image can be retrieved independently.
