A novel approach towards separable reversible data hiding technique

Internet is the most popular communication medium now a days but message communication over the internet is facing some problem such as data security, copyright control, data size capacity, authentication etc. There are so many research is progressing on the field like internet security, steganography, cryptography. When it is desired to send the confidential/important/secure data over an insecure and bandwidth-constrained channel it is customary to encrypt as well as compress the cover data and then embed the confidential/important/secure data into that cover data. This paper introduces the new way of originating the existing concept i.e. separable reversible data hiding. Actually the concept of separable reversible data hiding technique is based on steganography and related with internet security. The chief objectives of this literature is to work on the concept in which we used text as a hidden data, no plain spatial domain is used, attempt to increase the amount of data which is to be hide, evaluating quality by different interpretations. The principal notion of separable reversible data hiding is consist of three key procedures. First encrypt the cover media second hide the data and third get the data as well as cover media as per provisions.
