Abstract

An embodiment of the invention provides a common serial bus USB switching device with a download verification function and a download verification method. The device comprises a controller arranged in intelligent equipment, a USB interface and a download verification data module, wherein the download verification data module comprises a head part and a tail part; the head part comprises a USB interface plug and a verification chip which is connected with the USB interface plug and is used for storing verification information; and when the USB interface plug is connected with the USB interface, the controller can read and verify the verification information in the verification chip through the USB interface, and whether a download mode is allowed to be started or not is judged through a verification result. With the adoption of the technical scheme provided by the embodiment of the invention, when the system of intelligent equipment is reinstalled in a manner of downloading software, security verification measures are increased, and unauthorized system reinstalling accidents are prevented. Meanwhile, an original USB interface on the intelligent equipment is reused to realize a verification process, and the attractive appearance of the intelligent equipment is guaranteed.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of mobile devices, and in particular to a universal serial bus USB adapter device with a download verification function and a download verification method. Background technique [0002] Smart mobile devices represented by mobile phones and tablet computers have become an indispensable communication tool in people's lives, and as the functions of smart mobile devices become more and more powerful, the prices of many products are relatively high, and they have become criminals. The main target of stealing in the eyes. After successful theft, criminals may not be able to use it normally because they do not know the password set by the user, but they may download the software by connecting a common transmission interface such as a Universal Serial Bus (USB) on the mobile device, and clear the software. All the previous settings of the user, reinstall the system for the mobile device, t...
