Abstract

The project entitled "Steganography" is to give security to a content record. Since the security of the data over the internet has raised a concern to the people. There are many methods to protect the data from going into the access of unauthorized people. Steganography can be used along with the encryption technique to secure the data. Steganography is used to hide the data or a secret message whereas cryptography is used to encrypt the message and make it difficult the people to read. So, the proposed system is to combine both steganography and cryptography for the secret data transmission. The transmission can be done by using an image as a carrier of data. This paper uses high-performance BMP steganography along with a substitution encryption methodology. The approach that is used here is IDEA (International Data Encryption Algorithm) algorithm which is used for encryption. The IDEA algorithm works as follows, it will take the TEXT document and mystery key as the input and gives the encrypted and BMP picture as the output for the sender side. There can additionally be “Voice Recognition System” framework so that it can use voice to decrypt the message. This is the future expansion or scope of this paper.
