A fraud detection method using IS-41C protocols and its application to the third generation wireless systems

Wireless fraud, in particular that caused by cloning, has become a global problem in public wireless mobile communications services. To overcome this problem, many kinds of detection technologies such as profiling, RF fingerprinting, PIN, and call history counter have been proposed. However, these still do not provide a high degree of fraud detection. The proposed detection mechanism in this paper is based on a challenge-response protocol, and can detect the occurrence of mobile cloning with a high degree of confidence while requiring minimal system resources.
