Abstract: Nowadays there is the very big problem of data hacking into the networking era. There is the number of techniques available to overcome this problem. So, Data hiding is a technique for embedding information into covers such as image, audio, and video files, which can be used for media notation, copyright protection, integrity authentication, covert communication, etc., In this thesis, various existing Data Hiding techniques are studied and reviewed. In this thesis mainly focus on embedding data and restore data with better quality. This thesis discusses Reversible Data Hiding techniques based on Reversible image transformation to embed data and then extract data. The proposed techniques are applied and compared to find which methods are suitable for hiding data into the camouflage image and then losslessly restore the information
