Abstract: Describes the thought of Reversible Information Hiding (RDH) methodology is based on steganography. Recently a lot of attention is paid to RDH in encrypted image. Security should be provided for the transmission of confidential and sensitive information over the network and insecure channel, loss in information happens. To secure the information, encode the wrap information and introduce is secret information into cover media. so the protection of image and embedded information is maintained, Since RDH manages the outstanding secured property, and therefore the original image are often recovered with none loss, Reversible Information Hiding (RDH). Within the planned rule, Histogram Shifting (HS) is employed for RDH, and therefore the BHSEA methodology is used for encoding. The BHSEA methodology performs four processes for encoding; Reversible information hiding could be a form of information hiding techniques whereby the host image is often recovered specifically. Being lossless makes this method appropriate for medical, military applications and cloud storage. In cloud storage, a content owner will encode a picture to preserve his/her privacy, and transfer the encrypted knowledge onto cloud. Reversible knowledge activity in encrypted image, which might recover the first image with none distortion from the marked image when the hidden information, are extracted. Existing rule consists of various hierarchal steps for the information embedding and therefore the encoding. Therefore, the planned rule are often appropriate for the hierarchical  access system, wherever the permission is granted consistent with the assorted access rights and planned algorithmic rule up strength and authentication of image information hiding.
