USER AUTHENTICATION METHOD AND APPARATUS |
摘要 |
Authorization for a user to use a service is provided by a modified pager which calculates a unique response code to a transmitted challenge code based on the challenge code, an input personal identification number, and an internal key. The response code is input to a simple terminal, such as a telephone and if the unique response code is acceptable, the user may access the desired service, such as cashless transactions or long distance phone service.
