  1. Improving Response Time in Traffic Police Infraction Registration SystemH. Arasteh Rad, K. B. Samsudin, A. R. Ramli, A. Mohamad Bagher Tehrani, M. A. TavallaeeManuscript received March 28, 2009 Adviser: Tz-Heng Hsu Speak: Shao-Hsiang Hung Date:2009/12/8

  2. Outline • Introduction • The Mobile Traffic Police Communication Foundation • Improving Database Performance • Conclusions

  3. I. Introduction(1) • The number of registered motor vehicles in the world in recent years • Problem in road traffic enforcement • Limited resources of traffic police • Now traffic infraction registration • Still done manually by a pen and a notebook

  4. I. Introduction(2) • Mobile telecommunication application • Using a mobile phone on network • Anywhere, anytime • Enhance the existing registration method • Central database can updated in real time • Be convenient and efficient

  5. I. Introduction(3.1) • Some challenges in traffic police mobile telecommunication: • Client Devices • Small screen • Mobile phone battery • Limited processing resources and storage space • Cellular Network • The bandwidth limitation • Vulnerable to theft and loss

  6. I. Introduction(3.2) • Traffic Police Data Center (TPDC) • Update real time simply • Responsibility time • Security • Client authentication • Data encryption • Integrity

  7. II. The Mobile Traffic Police Communication Foundation

  8. II. The Mobile Traffic Police Communication Foundation • Mobile Client • SIM card acts as • A tampered resistant device • A cryptographic device • Menu-driven application • A specific PIN number activate the application • The SIMToolkit application • Packages all information into an encrypted message and sends it to the SG between GMS

  9. II. The Mobile Traffic Police Communication Foundation • Police Keys Sever • Main functionalities: • Generation new keys • Issues Keys to the SG • Maintains a database containing the valid Keys and Revocation Lists (CRLs). • For encryption and officer validation • Symmetric encryption algorithms

  10. II. The Mobile Traffic Police Communication Foundation • Police Keys Sever • To reduce the risk of key transmissions • A novel methods • Changing of exclusive key two parties periodically • For security improvement • A novel protocol • Regard to • Offender driving license data in TPDC • The police officer

  11. II. The Mobile Traffic Police Communication Foundation • A novel protocol

  12. II. The Mobile Traffic Police Communication Foundation • Police Keys Sever

  13. II. The Mobile Traffic Police Communication Foundation • Police Keys Sever • Encrypt the first message • Using TPDC issues the first key

  14. II. The Mobile Traffic Police Communication Foundation

  15. II. The Mobile Traffic Police Communication Foundation • Police Keys Sever • This confirmation message consists: • License confirmation • Daily_session_ID • Data and time

  16. II. The Mobile Traffic Police Communication Foundation • Police Keys Sever

  17. II. The Mobile Traffic Police Communication Foundation • Police Keys Sever • After issue traffic ticket • A new key generation • The first key from TPDC • Any predetermined date from POD • Encrypt traffic ticket and Daily_session_ID

  18. II. The Mobile Traffic Police Communication Foundation • Security Gateway

  19. II. The Mobile Traffic Police Communication Foundation • Security Gateway • The User Authentication Agent(UAA) module • The Access Point module (AP) • The Cryptographic module (CU)

  20. II. The Mobile Traffic Police Communication Foundation • Database

  21. III. Improving Database Performance • Optimizing the database • Proposed Method for Database Performance Tuning • Officer search request distributed across multiple servers • A dispatcher do load balancing • Request for insert send to whole servers • Request for search send to only one server

  22. IV. Experimental Result(1)

  23. V. Conclusions(1) • With growth of infraction manual method goes to be unusable. • Police communication • Security and be quick • Anywhere, anytime

  24. V. Conclusions(2) • we propose a secure traffic police data center • protect and establish their communication in authentication and confidentiality • Introduce our method tuning • minimize the response time • It can be extended to the other mobile information systems
