Abstract
Service is authorized through a process that employs a randomly sequenced table lookup that is based on predetermined information that was randomly assigned. In one embodiment, a calling card is issued with a table having a plurality of entries, with each entry comprising one or more digits. When wishing to make a call, the customer enters his/her ID. That ID is communicated to the service provider, based on that ID the provider retrieves from a database a table of the information that the customer has, and proceeds to request that the customer enter information pursuant to a random selection by the service provider.
