Embodiment Construction
[0040] The audio card is composed of an IC chip, a dynamic password generating module, a modulating module (converting the information and password generated by the IC chip into a sound signal in a predetermined format) and a sounding module. Gently press the audio card when using it. Once the audio card is activated, it will emit a series of sounds through the sound module. The sound contains account number, password and other information, which can be demodulated and utilized by the background server.
[0041] The present invention adds authentication server 90 in existing intelligent network, is used for authentication authentication to the validity of audio card, and it can be a separate equipment can be a software of business control point 91 (ServiceControl Point, SCP) modules such as figure 1 As shown, it is a schematic structural diagram of the system for authenticating through passwords in the present invention, including several communication terminals 92, and a serv...

The invention relates to a system which uses password to accredit. Wherein, it comprises: several communication terminals; service exchange point that communicating with communication terminals via communication network; service control point connected to the service exchange point; and accredit server connected to the service control point. The invention also provides a relative method, which comprises: the voice card uses accounts and first accredit message to generate voice signal, to be sent to the service exchange point via communication terminal; decoding the voice signal to be sent to the service control point; according to said accounts, obtaining the first message from database; then according to the first message, using preset algorism to obtain the second accredit message; according to the first and second accredit messages, processing accreditation; if the accreditation passes, using it normally, or forbidding using said voice card. The invention can realize the accreditation on the password dynamically generated by the voice card, to improve the safety of voice card.
Description
technical field [0001] The present invention relates to a system and method for authenticating through passwords, in particular to a system and method for authenticating users with passwords dynamically generated by audio cards in an intelligent network. Background technique [0002] Intelligent network is a system that can quickly, conveniently, flexibly, economically and effectively generate and realize various intelligent services. The system can serve all communication networks. For example: 800 called toll service, 300 debit card service, 200 telephone card service, etc. Information such as service account numbers and passwords are stored in the background server of the intelligent network. [0003] At present, the intelligent network manages the account password through a special management process, and the detailed process is as follows: [0004] First dial the management access code on the communication terminal, then input the card number and password according to...
