As per today's scenario, wireless networks are becoming more popular day-by-day as it is difficult for people to constrain their needs to wired networking. VANET works on the basis of real time system where the vehicles move as nodes and travel with a very high speed on roads. There are many security issues like authentication, tunnel attacks, intelligent system approach, collision detection, congestion avoidance, etc. A number of methods have been proposed to deal with various issues in VANET. In this paper, an enhance level of security is implemented on the VANET system to reduce malicious activities into the network. Here the security is done by the authentication of individual node by some enhanced scenario which is based on the HASH value and steganography technique and eye retina sample. Each vehicle will be authenticate by centralize authentication and it helps to reduce the malicious activities.
