Embodiment 1
[0047] Such as image 3 As shown, the present application provides a multi-interface authentication terminal 100, including an authentication chip 10 and at least two interfaces 20, and,
[0048] The working state judging module 30 is connected with the authentication chip 10 and is used for judging the working state of the authentication chip 10 . The authentication chip 10 is an existing chip, and the authentication chip 10 is used to authenticate authentication information sent by an external device. The authentication information may be fingerprint information or identity authentication information sent to the authentication terminal.
[0049] Specifically, the working state judging module 30 includes:
[0050] The monitoring unit 31 is used to monitor whether there is data transmission in the interface 20 in real time;
[0051] The judging module 32 judges whether the authentication chip 10 is in the working state according to the monitoring result; if the interface 20...
Embodiment 2
[0062] Such as figure 1 As shown, the present application provides a method for using a multi-interface authentication terminal, which includes the following steps:
[0063] Step S1, when at least two interfaces of the authentication terminal establish connections with external devices, determine whether the authentication chip is in a working state;
[0064] If it is in the working state, it means that an interface is being authenticated with an external device.
[0065] Such as figure 2 As shown, the method for judging whether the authentication chip is in working condition includes the following sub-steps:
[0066] Step S110, monitor in real time whether there is data output from the interface of the authentication terminal, and obtain the monitoring result.
[0067] Specifically, by connecting the input end of the working state judging unit with the interface, and connecting the output end of the working state judging unit with the authentication chip, according to whe...

Abstract
The invention provides a multi-interface authentication terminal and a using method thereof. The using method comprises the following steps that when at least two interfaces of the authentication terminal are connected with external equipment, whether an authenticationchip is in a working state or not is judged; if the authentication chip is in the working state, the I / O interface is preferentially allocated to the interface for authentication, and the authentication chip is forbidden to carry out authentication communication with external equipment through other interfaces; and if the authentication chip is in a non-working state, any unoccupied interface is allocated to communicate with the authentication chip so as to carry out authentication. The problem that in the prior art, communication conflicts occur when multiple interfaces are connected with external equipment at the same time is solved.
Description
technical field [0001] The present application relates to the field of communication technology, in particular to a multi-interface authentication terminal and a method for using the same. Background technique [0002] Existing terminals as identity authentication devices, such as USBKEY, use one interface to communicate with the authentication host, if multiple interfaces communicate with the authentication host (or external device) at the same time, there will be communication conflicts. [0003] Existing identity authentication devices often wish to use multiple interfaces to connect to the host (or external device) at the same time, for example, one interface communicates with the authentication host (or external device), and the other interface charges the identity authentication device. Contents of the invention [0004] The purpose of this application is to provide a multi-interface authentication terminal and its usage method, which solves the problem in the prior ...
