Contents Introduction Position determination GPS (Global Positioning System) Bluetooth Authentication process Authentication device Conclusions

Introduction authentication necessity o download s, o fill out forms for the government, o access to company private information position as factor of authentication (FOA) o GSM network, o Wi-Fi AP, o GPS or the other navigation system GPS as one of useful possibilities of FOA

Position determination Three basic conditions 1. space description 2. anchor points with known position 3. distance between subject and anchor point

GPS developed in the 1970s by U.S. Department of Defense initially designed for 24 satellites (about 32 satellites on the present)  km AGL  3.8 kms -1 extremely accurate clock (atomic clock in satellites and pseudoatomic clock in receiver) visibility at least 4 satellites (3-dimensional position) transmition time stamp in specially coded signal protocol - NMEA 0183 interfaces – UART, IIC, USB, SPI update position up to 4 Hz

Bluetooth wireless low-power technology for data exchange over short distances The other suitable wireless technologies: Wi-Fi Zigbee IQRF

Authentication process Communication sequence used for user authentication with position information

Authentication device authentication device is connected to user’s terminal via USB fingerprint reader alpha numeric display secure data repository GPS receiver

Conclusion position as new factor of authenti c ation basic principle of position determination exploitation of GPS and Bluetooth authentication process authentication device
