A Survey on Reversible Data Hiding using BPCS based Multimedia Steganography Combined with Cryptography

With the popularity of outsourcing data to the server, it is essential to secure the protection of data and empower the server to effortlessly deal with the data in the meantime. Under such demands, reversible data hiding away in encrypted multimedia (image, audio also, video) draws in more analysts consideration. Existing framework proposes a novel structure for RDH-EI based on reversible image transformation (RIT). In this paper reversible transformation is carried on data and it is encrypted utilizing AES algorithm and again it is hidden into media document utilizing powerful BPCS algorithm. Again this hid media document is encoded utilizing standard AES algorithm. Also, it applies turn around operations at the recipient's side. Generally operations give a productivity and strength to the framework. RIT-based structure permits the user to transform the content of unique image into the content of another objective image with a similar size. The transformed image, which looks like the objective image, is utilized as the encoded image, and is outsourced to the server. In this paper AES algorithm is utilized to encode the mystery data and BPCS stegnography algorithm for hiding the encoded discharge data in multimedia files which can fulfill security and extensive inserting limit issue. The current framework was not worked for audio and video. In this paper usage on audio furthermore, video is continued. The discharge data will be cover up in the audio and video like image and will transfer on the server. Receiver will get the audio and video records from server and get the emit message from it. Which can fulfill distinctive necessities on image quality and extensive inserting limit separately.
