Abstract

An embodiment of the present invention provides a firmware, an electronic device, and an information processing method, wherein the firmware includes: a judging module configured to: respond to the device information of a peripheral device, and judge a matching result of the device information; the judging module It is not writable; the firmware at least: guides the operating system of an electronic device based on the matching result; the electronic device runs based on the above-mentioned firmware. In the firmware of the embodiment of the present invention, the judging module is set to be non-writable, and peripheral equipment or technical personnel cannot modify the judging module, nor can it affect the judging result of the judging module. In this way, the electronic device is more secure and can provide a better security experience for the user.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of electronic equipment, and in particular, to a firmware, an electronic equipment using the firmware, and an information processing method. Background technique [0002] After the peripheral device is connected to the computer through the USB interface, the data in the computer can be modified through the USB interface, that is, it has read permission and write permission at the same time. In order to protect the security of the computer, prevent the data in the computer from being illegally modified. In the prior art, in the Linux system, Grub can be set to disable the USB interface by modifying modprobe.conf, or the USB interface can be added to the blacklist, or the third-party software can also be used to restrict the reading of the USB interface. write function. In the Shell system or Dos system, you can also prevent others from entering the Shell system or Dos system by set...
