Secure Data Transmission Integration of Genetic Algorithm and Visual Cryptography Technique

摘要

Integrity, security, non-repudiation, confidentiality, and authentication services are the imperative elements in data security. Presently days the security of information draws much attention, particularly when these information are send through the communication network or put away in memory. Cryptography is a technique for sparing and transmitting information in a specific form so that those for whom it is proposed can read it and process it. For secure data transmission this work presented a system which uses genetic algorithm, steganography along with visual cryptography. Genetic algorithm is used for encryption where plain text is converted into cipher text then it is hidden in LSB pixels of an image using Steganography technique. Visual cryptography technique is then used to divide the image into multiple shares to provide security and reliability for data transmission over network. Digital signature is used for authentication.
