摘要：Ever since the world war, the call for information security raised. The explosion in World Trade Centre alarmed the people to work more towards secured travel of data. Then Steganography came to rescue, as here communication is also obscured. In many of the applications size of the secret data will be less than that of the size of the Cover Image which results in wastage of bandwidth. In this proposed study, multi-user embedding is carried out and is implemented for 5 users. Secret data of all the users is first encrypted by using Advanced Encryption Standarad (AES) and then by Ron Rivest, Adi shamir and Leonard Adleman(RSA) which escalates the complexity. A graceful graph is used for fixing the randomized order of embedding. Priority in the order of embedding among the five users will be changed during every cycle.
