Enhancing User Authentication Through Position Information: GPS and Bluetooth Applications

This paper explores the integration of position information, specifically through GPS and Bluetooth technologies, into user authentication processes. With the increasing need for secure access to sensitive data such as emails and government forms, position becomes a critical factor in determining user authenticity. The paper outlines the authentication process, the role of various devices (like fingerprint readers and GPS receivers), and the necessary conditions for accurate position determination. It emphasizes the importance of leveraging advanced technologies for improved security in information management.

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

  3. Introduction • authenticationnecessity • downloademails, • fill out forms for the government, • access to company private information • position as factor of authentication (FOA) • GSM network, • Wi-Fi AP, • GPS or theother navigation system • GPS as one of usefulpossibilities of FOA

  4. Position determination Three basic conditions • space description • anchor points with known position • distance between subject and anchor point

  5. GPS • protocol - NMEA 0183 • interfaces– UART, IIC, USB, SPI • update position up to 4 Hz • developed in the 1970s by U.S. Department of Defense • initially designed for 24 satellites (about 32 satellites on the present) • 20 200 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

  6. Bluetooth • wireless low-power technology for dataexchange over short distances • The other suitable wireless technologies: • Wi-Fi • Zigbee • IQRF

  7. Authentication process Communication sequence used for user authentication with position information

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

  9. Conclusion • position as new factor of authentication • basic principle of position determination • exploitation of GPS and Bluetooth • authentication process • authentication device
