摘要

With the increasing popularity of information technology in communication network, security has becomean inseparable but vital issue for providing for confidentiality, data security, entity authentication and dataorigin authentication.Steganography is the scheme of hiding datainto a cover mediato provideconfidentiality and secrecy without risking suspicion of an intruder. Visual cryptography is a new techniquewhich provides information security using simple algorithm unlike the complex, computationally intensivealgorithms used in other techniques like traditional cryptography. This technique allows visual informationto be encrypted in such a way that their decryption can be performed by the Human Visual System (HVS),without any complex cryptographic algorithms. To provide a better secured system that ensures high datacapacity and information security, a multilevel security system can be thought for which can be built byincorporating the principles of steganography and visual cryptography
