This is a ppt on mobile cloning which is an emerging technology.This technology is being used widely these days,and also this technology offers great help towards data replication and cloning device to device data.. which performs fucntions exactly same as the other device

4. INTRODUCTION
▪ Cell phone cloning is copying the identity of one mobile
telephone to another mobile telephone.
▪ Usually this is done for the purpose of making fraudulent
telephone calls.
▪ The bills for the calls go to the legitimate subscriber. The
cloner is also able to make effectively anonymous calls

5. CONTINUED…
▪ ESN- The ESN (Electronic Serial Number) is the serial number
of your cellular telephone.
▪ The ESN is transmitted to the cell site and used to verify that
you are a legitimate user of the cellular system.
▪ The MIN (Mobile Identification Number) is simply the phone
number of the cellular
telephone.

6. IMEI
▪ IMEI stands for International Mobile Equipment Identifier, this is a 10
digit universally unique number of our GSM handset.
▪ It is used in tracking mobile phones.

7. GSM AND CDMA
▪ CDMA( Code Division Multiple Access). A method for transmitting
simultaneous signals over a shared portion of the spectrum. There is no
Subscriber Identity Module (SIM) card.
▪ CDMA use a Mobile Identification Number (MIN) card that contains user
account information.
▪ GSM (Global System for Mobile) Communications. GSM uses a variation of
Time Division Multiple Access (TDMA) and is the most widely used of the
three digital wireless telephone technologies (TDMA, GSM, and CDMA).

8. CONTINUED…
▪ GSM digitizes and compresses data, then sends it down a channel with
two other streams of user data, each in its own time slot.
▪ It operates at either the 900 MHz or 1,800 MHz frequency band.

9. MOBILE CLONING
▪ Each phone has an Electronic Serial Number (ESN), identifying the
phone, as well as a Mobile Identification Number (MIN), which includes
the telephone number of the phone.
▪ These are used to identify the subscriber.
▪ When placing a call, the phone transmits both the ESN and the MIN to
the network.
▪ Esn and MIN can be received using a suitable scanner

10. CONTINUED…
▪ These codes would then be programmed into another phone,
effectively cloning the original subscription.
▪ Any calls made on this cloned phone would be charged on the
original customer.

12. METHODS TO DETECT CLONED
PHONES ON THE NETWORK
▪ DUPLICATE DETECTION The network sees the same
phone in several places at the same time. Reactions include
shutting them all off so that the real customer will contact
the operator because he lost the service he is paying for so
that the clone users will switch to another clone but the
real user will contact the operator.

13. CONTINUED…
▪ PIN CODES. Prior to placing a call, the caller unlocks the
phone by entering a PIN code and then calls as usual. After
the call has been completed, the user locks the phone by
entering the PIN code again. Operators may share PIN
information to enable safer roaming.

14. CONTINUED…
▪ RF (RADIO FREQUENCY) - fingerprinting is originally a
military technology. so the network software stores and
compares fingerprints for all the phones that it sees. This
way, it will spot the clones with the same identity but
different fingerprints.

15. CONTINUED…
▪ USAGE PROFILING. - Profiles of customers' phone
usage are kept, and when discrepancies are noticed, the
customer is contacted.
▪ For example, if a customer normally makes only local
network calls but is suddenly placing calls to foreign
countries for hours of airtime, it indicates a possible clone.

16. CONTINUED…
▪ CALL COUNTING - Both the phone and the network keep track
of calls made with the phone, and should they differ more than the
usually allowed one call, service is denied.

17. CLONING GSM PHONES
▪ Every GSM phone has a 15 digit electronic serial number
(referred to as the IMEI).
▪ The important information is the IMSI, which is stored on
the removable SIM card that carries all your subscriber
information

18. CONTINUED…
▪ The process of hacking GSM networks is simple: a SIM card is
inserted into a reader.
▪ After connecting it to the computer using data cables, the card
details were transferred into the PC.
▪ Then, using freely available encryption software on the Net, the card
details can be encrypted on to a blank smart card.
▪ The result: A cloned cell phone is ready for misuse.

19. HOW TO KNOW THAT THE CELL
HAS BEEN CLONED?
▪ Frequent wrong number phone calls to your phone, or hang-ups
▪ Difficulty in placing outgoing calls.
▪ Difficulty in retrieving voice mail messages.
▪ Incoming calls constantly receiving busy signals or wrong numbers.
Unusual calls appearing on your phone bills

20. TO PREVENT CLONING
▪ User verification using Personal Identification Number (PIN) codes is
one method for customer protection against cellular phone fraud
▪ Tests conducted have proved that United States found that having a
PIN code reduced fraud by more than 80%.
▪ Traffic analysis detects cellular fraud by using artificial intelligence
software

21. CONTINUED…
▪ Software detects suspicious calling patterns, such as a sudden
increase in the length of calls or a sudden increase in the number
of international calls.
▪ The software also determines whether it is physically possible for
the subscriber to be making a call from a current location, based
on the location and time of the previous call

22. CONTINUED…
▪ BLACKLISTING of stolen phones is another mechanism to
prevent unauthorized use.
▪ An Equipment Identity Register (EIR) enables network operators
to disable stolen cellular phones on networks around the world

23. IMPACT OF CLONING
▪ Each year, the mobile phone industry loses millions of dollars in
revenue because of the criminal actions of persons who are able to
reconfigure mobile phones so that their calls are billed to other
phones owned by innocent third persons.
▪ Many criminals use cloned cellular telephones for illegal activities,
because their calls are not billed to them, and are therefore much
more difficult to trace

24. CONCLUSION
▪ Preventive steps should be taken by the network provider and the
Government the enactment of legislation to prosecute crimes related
to cellular phones is not viewed as a priority
▪ Existing cellular systems have a number of potential weaknesses that
were considered. It is crucial that businesses and staff take mobile
phone security seriously.
