Today most of the communication takes place through web and people are using internet for every day communication. Because of the large advancements in Internet Technology the indispensable need of security for protection of data from the assorted hackers also rises. Cryptography and Steganography both are widely used techniques for secured data transmission. Where Cryptography is a technique which distorts a message and Steganography hides the message/data. For Encryption of secret message we will use AES and then image will be embedded using LSB algorithm which carries our confidential data. The amalgamation of both AES and LSB algorithms will take place to grant Security with confidentiality during communication of the secret data. The main objective of the paper is to assign security levels in the secret data which needs to be converse through the cover image. From the review of literature it is found that there is need to offer confidentiality to the secret message/data by merging the Cryptographic Techniques in Steganography.
