Secure Location Validation with Wi-Fi Geo-fencing and NFC

With rapid growth in technology and increase use of mobile devices, many enterprises have started to move away from fixed workstations to wireless mobile workstations. Moreover, some of the mobile applications may require access to sensitive data with the permissions being determined by the current location of a user. Typical access control systems are expensive and hard to maintain, especially systems that include location based access control. The complications arise from the purchase of additional equipment and time to integrate and secure a solution into the existing system. In such systems, one of the biggest problems is to figure out a cost effective and easy to implement solution to a problem of access permissions being determined by the current location of a user. In this paper we propose a simple scheme that uses near field communication technology along with Wi-Fi access point to securely validate the location of a user. Our scheme is efficient, secure and can be incorporated with other existing access control systems.
