1. A method for reducing fraudulent activity in a telecommunication network, comprising the step of:

  • automatically and selectively invoking at least one authentication measure during a call processing state for a particular call as a function of scoring calls for the likelihood of fraud, wherein the at least one authentication measure is selectively invoked based on a fraud score, the fraud score being derived as a function of a legitimate subscriber signature and a fraud signature, such that fraudulent activity in the network is reduced on a targeted basis thereby reducing disruptions to legitimate activity in the network.
