Abstract: An authentication-authorization system for a mobile communication terminal and a method therefor are provided. When a mobile communication terminal is in a connect state, code data randomly generated by a remote encoding terminal is continuously provided to the terminal and data management terminal. When an application service program on the mobile communication terminal or an application service terminal connected to the mobile communication terminal need to execute an authentication-authorization, identification data of the mobile communication terminal and its card and code data can be offered to the data management terminal to carry out a bidirectional dynamic authentication-authorization, to determine whether allow the application service program or the application service terminal to keep providing an application service or not.

Abstract: A BIOS configuration memory-clearing detection circuit and a method of clearing a BIOS configuration memory for computer main board uses a latching circuit to detect whether a user has set a clearing of the BIOS configuration memory. If the user has set a clearing of the BIOS configuration memory, the latching circuit sets a clearing latch signal. When the computer subsequently switches on, a ROM BIOS reads the status of the clearing latch signal. If the clearing latch signal is set, the ROM BIOS further clears the BIOS configuration memory to ensure the clearing operation is successful.

Abstract: A card certification and authorization system and method is disclosed. When a cardholder swipes a card at any terminal device and initiates the process of authorization, the data storage management system executes instantaneous bidirectional comparisons of the encoding data. It reduces the risk produced by the unidirectional certification and authentication. When the comparisons succeed and authorization is allowed, the encoding system can instantly produces new coding data randomly to be used as stored record to illuminates the chance of the card information being stolen. When the comparisons fail and authorization is denied, the data storage management system will put the account on hold and start the notification process using the terminal device, which decreases the chance of the card being used without authorization. The comparisons of the encoding data and the process of storing data need to be converted using conversion and encryption program to ensure data safety.
