Effective Authentication for Restricing Unauthorized User

Currently systems are protected using many firewalls and security software. The existing system can be easily compromised. The aim of system is to provide effective authentication to unauthorized users by providing three tier authentications which are Face detection, Fingerprint and OTP. The proposed system uses real-valued or binary random projections to effectively compress the fingerprints at a small cost in terms of matching accuracy. The proposed methodology provides more control of owner on the data stored on system by restricting the access to specific user for specific file with limited privileges and for limited time period on the basis of secret key using symmetric as well as asymmetric mechanism. The integrity and confidentiality of data is ensured doubly by not only encrypting the secret key but also to the access permission and limited file information. Especially, the purpose of the one-time password is to make it more difficult to gain unauthorized access to restricted resources. To overcome these drawbacks, the attraction of the AES512 will be introduced after our one-time password authentication protocol. Thus the proposed system is more secured and can be utilized effectively.
