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.
