Embodiment Construction

[0013] Such as figure 1 Shown is the structural principle diagram of the present invention. The USB-based process protection card includes a USB interface, including a USB interface unit, a bus interface unit, and a central processing unit. The USB interface unit communicates with the central processing unit through the bus interface unit. The USB interface unit is connected to the USB interface of the computer. The USB interface unit receives the protected process data from the computer and transmits the data to the central processing unit through the bus interface unit. The central processing unit responds to the received The data is read to determine whether the computer is working in the running state of the protected process and control the computer to turn on.

[0014] The bus interface unit is a central processing unit, and the USB interface is connected to the central processing unit through the bus interface unit. The bus interface unit is CH372 / CH375 chip. The central ...

Abstract

The invention relates to a progress protection card based on a USB (Universal Serial Bus), which comprises a USB interface, a USB interface unit, a bus interface unit and a CPU (Central Processing Unit), wherein the USB interface unit is connected with the CPU by the bus interface unit and connected with a USB interface of a computer, receives protected progress data from the computer, and transmits the data to the CPU through the bus interface unit, and the CPU reads the received data, judges whether the computer operates in a protected progress running state, and controls starting of the computer. The protection card can completely and reliably protect a protected progress.

Description

Technical field [0001] The invention relates to a USB-based process protection card. Background technique [0002] The management unit (such as the Municipal Security Bureau manages all office computers in the city) or the management department (such as the internal network management center of the unit) need to install software on the computer of the user (the managed object) for the convenience of management. However, the installed software is often uninstalled by the user or the process is terminated, making the management useless (because of this problem in some places, work in this area has not been carried out). [0003] In order to prevent users from uninstalling the software or ending the process, some departments use software to protect the process, but its own security is another problem. In addition, some users start the computer with a U disk or a mobile hard disk, which also avoids the supervision of users by management software. Summary of the invention [0004] In ...
