Method, device and system for obtaining authentication code of integrated circuit card

[0120] An embodiment of the present invention provides a method for obtaining an authentication code of an integrated circuit card. In the process of obtaining the authentication code, the client first logs in to the processing platform, and then applies for obtaining the authentication code after logging in. image 3 Flowchart for the client to log in to the processing platform, Figure 4 After logging in to the processing platform for the client, the flow chart of the authentication code acquisition method includes the following processing steps:

[0121] Step 301, the client sends a connection request to the processing platform.

[0122] In this step, the client sends a TCP / IP connection request to the processing platform, and the connection request includes the IP address of the client.

[0123] Step 302, the processing platform searches in the database whether there is record data corresponding to the IP address of the client, if no, go to step 303, if yes, go to step 304

[0172] Based on the same inventive concept, according to the method for obtaining the authentication code of the integrated circuit card provided by the above-mentioned embodiments of the present invention, correspondingly, Embodiment 2 of the present invention also provides a device for obtaining the authentication code of the integrated circuit card, and its structural diagram is as follows Figure 5 shown, including:

[0173] The obtaining unit 501 is used to obtain the globally unique number UID of the integrated circuit IC card sent by the client and the IP address of the client;

[0174] A search unit 502, configured to search the database for the company name and area number corresponding to the client to which the IP address belongs;

[0175] The first sending unit 503 is configured to send the found company name, area number, and UID to the authentication code generation server;

[0176] The second sending unit 504 is configured to send the received authentication code

[0196] Based on the same inventive concept, according to the method for obtaining the authentication code of the integrated circuit card provided by the above-mentioned embodiments of the present invention, correspondingly, Embodiment 3 of the present invention also provides a device for obtaining the authentication code of the integrated circuit card, the schematic diagram of which is as follows Figure 6 shown, including:

[0197] The sending unit 601 is used to send the global unique number UID of the integrated circuit IC card and the IP address of the client to the processing platform;

[0198] The first obtaining unit 602 is configured to obtain the authentication code corresponding to the UID sent by the processing platform, and the authentication code is that the processing platform searches the database for the client to which the IP address corresponds. Company name and area number, after sending the found company name, area number, and the UID to the authentication cod
