Mobile networks provide distinct set of services for the user in which authentication is one of the imperative and significant types of services. There are various factors of authentication. Some of them are passwords, security token, retinal scan, fingerprint, and other bio-metric data, etc. The other new factor is the user's location which can also be used as one of the criteria for remote client authentication. However, the information of location is private and can be misused; hence distinct procedures should be implemented to ensure its integrity. In this paper, we propose the use of location based services to provide authentication to a remote client. As a use case, we consider the Automated Teller Machine (ATM), which is one of the most popular targets of fraud today. A remote client is provided with necessary authentication using the location based services, defined by the Expand LRAP (Location based Remote client Authentication Protocol), so as to make him aware of a genuine ATM where he can carry out secure transactions.
