Offline terminal access control system

Abstract

The invention discloses an offline terminal access control system. The system comprises a mobile phone client, a plurality of offline terminals and a server, the server is connected with the mobile phone client through a network; the server comprises a short message verification module, a dynamic password generation module, an uploading module, a central management module, an information registration port and a password control port. The offline terminal comprises a two-dimensional code generator, a display port and an administrator port; the dynamic password generation module transmits the dynamic password to the uploading module through the password control port; the uploading module transmits the dynamic password information to the mobile phone client, the central management module records the mobile phone number and time of the operation and feeds back the information to the password control port, and a user inputs a dynamic password at the administrator port of the offline terminal and relieves the access permission. The offline terminal without network connection can be subjected to access control, the control means are relatively diverse, the control cost is extremely low, and the application prospect is wide.

Description

technical field [0001] The invention relates to a control technology for terminal access, in particular to an offline terminal access control system. Background technique [0002] In the existing common computer terminal access control systems, users are controlled to access the terminal without authorization. Most access control systems are similar to the billing system of Internet cafes, requiring an available network connection between the computer terminal and the server to control the access of the terminal. . Others use physical key access, but cannot achieve more precise access control, and the hardware cost is high. [0003] Moreover, for some terminals that are in the intranet or have no network connection, it is impossible to restrict their login in the offline environment of the terminal, and the method of manual registration and changing the password every time after use cannot meet the requirements of large-scale, high-frequency secondary usage scenarios. SU...
