Multi-level Steganography Technique with Multiple Cryptography Algorithm

Uzma Ali, Kranti Dewangan
Recently, the use of Internet have been increase and also exceeded in security issues. Information security is a important component in Internet. The technique used in information security is Steganography and Cryptography. The Steganography allow covering of information while Cryptography provides scrambling of information. The combination of both provides more information security. In the proposed method we use Multi-level Steganography Technique in which Steganography is done in three places
