Sniffer for detecting lost mobile ppt
- 1. Sniffer for detecting lostmobile By Asmita Tarar Amravati
- 2. What Happens whenyou lost your Mobile Phone?
- 3.
- 4. But still notfound?
- 5. What is thebest Solution then?
- 6. What is thebest Solution then? Sniffer
- 7. What is Sniffer?•Precise • Small Size • Mobile Base Station • Unidirectional Antenna • Tracking S/W
- 8.
- 9. What Sniffer actuallyhas? Small Base Station Plays major role Transceiver section operated at frequency (different) Directional antenna Includes:
- 10. What is IMEI? (InternationalMobile Equipment Identifier)
- 11. What is IMEI? In 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. What is IMEI? In 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. Gray List Allow thePhone 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. Designing for theSniffer1.SNIFFER BASE STATION 2.UNIDIRECTIONAL ANTENNA 3.TRACKING S/W
- 15. Design Of UnidirectionalAntenna 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. Sniffer Base Station Designingfor 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. S/W for theTracking 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. S/W for theTracking Designing for the Sniffer - S/W for the Tracking RAM IMEI Number Lost mobile Signaling information i/p
- 19. Working of aSniffer 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. Before Sniffer IncreaseThe Frequency
- 21. After Sniffer IncreaseThe 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. Sniffer tries toCommunicate with the Lost Mobile
- 23. Is browser sniffingthe only viable approach for mobile device detection?
- 24. ADVANTAGES• Useful forlost mobile • effective cost • low power consumption • easy to design
- 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”
