This document summarizes information about mobile phone cloning, including how it works, its symptoms, methods of detection and prevention. It discusses that cloning involves copying the identity of one mobile phone to another so bills go to the legitimate subscriber. It provides details on GSM and CDMA networks and terms like IMEI, SIM, ESN and MIN. Symptoms of cloning include wrong numbers, hang ups, problems making calls and large bills to unknown numbers. Detection methods include duplicate detection and usage profiling while prevention includes blacklisting stolen phones and using PIN codes. Fraud from cloning costs the industry millions annually.

3. INTRODUCTION
CLONING: Cloning is the creation of an organism
that is an exact genetic copy of another. This
means that every single bit of DNA is the same
between the two!
MOBILE PHONE CLONING: Mobile phone cloning
is copying the identity of one mobile telephone to
another mobile telephone. The bills for the calls
go to the legitimate subscriber.

4. GSM & CDMA MOBILE
SETS
• CDMA( Code Division Multiple Access). A
method for transmitting simultaneous signals
over a shared portion of the spectrum.
• GSM (Global System for Mobile)
Communications. Any GSM phone becomes
immediately programmed after plugging in the
SIM card.

5. IMPORTANT TERMS
• IMEI stands for International Mobile Equipment Identifier.
• SIM, which stands for Subscriber Identification Module.
• ESN, which stands for Electronic Serial Number.
• MIN stands for Mobile Identification Number.

6. HOW IS A PHONE
CLONED?

8. What Are The Symptoms?
• Frequent wrong numbers
• Calls that hang up after you answer
• Problems making outgoing calls
• Incoming calls that constantly get the busy signal
• Large phone bills to numbers you’ve never heard of
• Problems accessing your voicemail

9. METHODS TO DETECT
CLONED PHONES
• Duplicate detection
• Velocity trap
• Usage profiling
• Call counting
• PIN codes

10. HOW TO PREVENT CLONING?
• Blacklisting of stolen phones is another mechanism to prevent
unauthorized use.
• User verification using Personal Identification Number
(PIN) codes.
• Tests conducted have proved that United States found that
having a PIN code reduced fraud by more than 80%.
• Traffic analysis

11. FACTS AND FIGURES:
• Southwestern Bell claims wireless fraud costs the
industry $650 million each year in the US.
• More than 1500 telephone calls were placed in a single
day.
• Estimated loss at $3000 to $4000 for each.
• Telecom regulatory authority of India should issue
directive, which holds the operators responsible for
duplications.
