....the call into the network. PINs are in use throughout many metropolitan areas in the United States. Unfortunately, like MIN ESN pairs, PINs are broadcast over the airwaves unencrypted. For technical reasons, PINs are more difficult to receive and decode, but with more sophisticated equipment PIN cracking is possible (Herzog 1995). Although PINs make cloning fraud more difficult, they do not prevent it. Other methods of prevention include RF Fingerprinting and Authentication (Redden 1996) RF Fingerprinting is a method of identifying cellular phones by their transmission characteristics. Authentication is a reliable and ....

....indicators of fraud in the form of classification rules. Similar to other MetaDENDRAL style rule learners (Buchanan and Mitchell 1978; Segal and Etzioni 1994; Webb 1995) RL performs a generalto specific search of the space of conjunctive rules. This type of rule space search is described in detail by Webb (Webb 1995). In DC 1, RL uses a beam search for rules with certainty factors above a user defined threshold. The certainty factor we used for these runs was a simple frequency based probability estimate, corrected for small samples (Quinlan 1987) In order to deal with the very large numbers of values for ....
