ABSTRACT:
This invention relates to a cellular telecommunications systems that utilizes the telephone number the cellular telephone is calling, with the number of telephone calls placed on that cellular telephone, i.e., call count and a seed number to create a digital certificate of the data. The digital certificate is used to make it more difficult to make unauthorized cellular telephone calls. The seed number may be changed after a predetermined number of calls has been made, i.e. one hundred, one thousand, etc. Thus, the transmission of seed numbers between data centers would be substantially reduced.
