Internet is the popular communication media now a days but message transfer over the internet is facing some problem such as data security, copyright control, data size capacity, authentication etc. Data hiding plays an important role in data security. It is a process in which secret data or information is stored or hidden into cover media. And so many researches are progressing on the field like intern et security, steganography, and cryptography. When transfer the secure data over an insecure channel it is needed to encrypt cover or original data and then embed the secure data into that original or cover image. This project introduces the new way of ori ginating the previous concept i.e. separable reve rsible scheme for data hiding. Actually, the separable reversible data hiding technique is based on steganography and related with internet security. Data hiding process is a combination of set of the embe dded secret data and a set of the cover media or original image. The main objectives of this literature is to work on the concept in which we used text as a hidden data, attempt to increase the amount of data which is to be hide in the cover image, evaluat ing quality of image by different interpretations. The principle of separable reversible data hiding is consisting of three key procedures. First is encrypt the cover image second hide the data in encrypted image and last extract the secret data from the c over image
