摘要：The internet and the World Wide Web have revolutionized the way in which digital data is distributed. The growing possibilities of modern communication need special means of security especially on computer network. In this paper a new randomized secure data hiding algorithm using file hybridization is proposed for strengthening the security of information through a combination of cryptography and steganography with random transformation and file hybridization. Cryptography concentrates on rendering the message unreadable to any unauthorized persons who might intercept them and steganography provides security by concealing existence of information being communicated. The proposed method, viz. Randomized Secure Data Hiding Algorithm using File hybridization (RSDHAF), is divided into sender side and receiver side parts which consist of combination of phases. File hybridization technique adds extra mystification to the analyst in finding the secret message. Simulation results show that the method provides high security and the information is safe from various attacks.
