Reversible information hiding may be a wide used technique on the idea of watermarking. The host image will be recovered specifically. Reversible information activity technique is applied at medical and military applications. the information embedding method can sometimes introduce permanent loss to the cover medium. In many fields like medical, military, and law forensics degradation of cover isn't allowed. Reversible information activity algorithms in encrypted pictures (RDHAEI) with bar graph, since it maintains the excellent property that the first image cover will be losslessly recovered once information embedded is extracted whereas protective the image content’s as confidential. Reversible information activity techniques recover the first carrier specifically once the extraction of the key encrypted information. Reversible information concealment Techniques are classified supported the strategy of implementation. During this paper a survey on the various techniques applicable supported distinction expansion, bar graph shifting. during this survey paper totally different reversible information hiding strategies are analyzed. All previous strategies insert information by reversibly encrypted pictures and information extraction and/or image restoration. Reversible information concealment that permits pictures to information in hidden type and improved to their origin by removing digital hidden information.
