At every airport authentication of passenger is necessary for security as well as customer relationship. A biometric authentication system is designed for efficient real-time monitoring as well as to maintain transparency in authentication of passenger(s) which will be connected to any information system at the airport. In this proposed system can be deployed at any airport. Each individual has a unique pattern of fingerprint which he can be recognised easily and can be used for biometric authentication which shows presence of each passenger in flight. In this paper we discuss about an important approach to capture and authenticate fingerprint in verification process. We can achieve this approach using CENTRAL AADHAAR IDENTIFICATION RESPOSITORY (CIDR).This service can be easily availed by anyone requesting to authenticate their customer employee or any other associate [1]. Information system will generate a ticket with regarding to PNR number using fingerprints.
