Abstract
A fraud prevention system and method are provided which utilize communication between an intelligent network platform 14 and a local telecommunications device 10. The local telecommunications device 10 comprises a memory 20 which stores various data values. Intelligent network platform 14 comprises a memory 22 which stores a copy of the values in memory 20. The intelligent network platform 14 randomly generates an address which is transmitted to the local telecommunications device 10. The local telecommunications device 10 retrieves data located at the address and transmits the data to the intelligent network platform 14 as an access string prior to the placement of telephone calls using the intelligent network platform 14. The time and day of the telephone call may also be included in the access string to prevent signals recorded at one time from being used to place telephone calls at another time.
