  6. 6. What is the best Solution then? Sniffer
  7. 7. What is Sniffer?• Precise • Small Size • Mobile Base Station • Unidirectional Antenna • Tracking S/W
  8. 8. What Sniffer actually has?
  9. 9. What Sniffer actually has? Small Base Station Plays major role Transceiver section operated at frequency (different) Directional antenna Includes:
  10. 10. What is IMEI? (International Mobile Equipment Identifier)
  11. 11. What is IMEI? I n t e r n a t i o n a l M o b i l e E q u i p m e n t I d e n t i f i e r • Unique number • Used for blocking of call made by unauthorized person • 15 digit unique code • identify-GSM/DCS/PCM • check EIR
  12. 12. What is IMEI? I n t e r n a t i o n a l M o b i l e E q u i p m e n t I d e n t i f i e r If EIR & IMEI matched NETWORKS CAN DO NO. OF THINGS TO KNOW IMEI NUMBER DIAL *#06# BUT, We use IMEI EFFECTIVELY in SNIFFER For the purpose of DETECTON
  13. 13. Gray List Allow the Phone to be used, but can be tracked to see who has it. Black ListListing the phone from being used on any number where there is an EMI match
  14. 14. Designing for the Sniffer1.SNIFFER BASE STATION 2.UNIDIRECTIONAL ANTENNA 3.TRACKING S/W
  15. 15. Design Of Unidirectional Antenna Designing for the Sniffer - Design Of Unidirectional Antenna • Act as a eyes for the sniffer • Antenna is a device works at specified frequency • Transmitting & receiving data signal • Transmit power • Used to show radiation pattern (Unidirectional Antenna Radio Pattern)
  16. 16. Sniffer Base Station Designing for the Sniffer - Sniffer Base Station • Small base station • Include transceiver section • Operated at frequency (900mhz which is VHF range) • OSCILLATOR circuit-for frequency range • Important is cooling • Low power transmitter (help in nature)
  17. 17. S/W for the Tracking Designing for the Sniffer - S/W for the Tracking • Feature: help to create database using RAM • IMEA - embedded in a chip • RAM stores - IMEI no. • Act as a database
  18. 18. S/W for the Tracking Designing for the Sniffer - S/W for the Tracking RAM IMEI Number Lost mobile Signaling information i/p
  19. 19. Working of a Sniffer Device• Sniffer works as a transceiver • BTS (Base Transceiver Station) - Act as a middle man • MTSO (Mobile Telephone Switching office) = MSC(Mobile Switching Centre)
  20. 20. Before Sniffer Increase The Frequency
  21. 21. After Sniffer Increase The Frequency IMEI no. provided by MTSO or MSC BTS(base transceiver station)-act as a middle man MTSO(mobile telephone switching office)=MSC(mobile switching centre)
  22. 22. Sniffer tries to Communicate with the Lost Mobile
  23. 23. Is browser sniffing the only viable approach for mobile device detection?
  24. 24. ADVANTAGES• Useful for lost mobile • effective cost • low power consumption • easy to design
  25. 25. ConclusionCertain boundaries : • Power of mobile should be good enough • mobile should not been in shadow regain Note: “Method can been improved by using modern technology and devices”
