Dynamicity in the data sharing has resulted in resource usage being more and more distributed and more open in nature. The need for problem solving and the distributed nature of data has resulted in the development of grid environment. Authentication is the first step of security requirement for any grid environment to validate the user. This paper proposes an authentication method which is depends on the password and the user ID along with the biometric data of the user and the geographic position of the user. The same biometric and position data used for authentication can be used for authorization purposes so as to reduce the cost and time of storing different data for different purposes.
