Problems solved by technology

The USB storage device one-way control technology controls the storage medium connected to the computer to prevent information from being leaked from the mobile storage device intentionally or unintentionally. With this method, the user can set the storage device usage permission according to the need, but the USB storage device needs to be set in advance. It is inconvenient for the user to insert the storage device into the computer for setting, and this method is immature and has certain defects

Embodiment Construction

[0026] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.

[0027] Such as figure 1 Shown, a kind of password-based USB access control method, it comprises the following steps:

[0028] S1: The user connects the USB device to the computer USB port;

[0029] S2: The computer judges the USB device. If the connected USB device is a non-storage device, it does not need to enter a password to directly connect to the computer; if the connected USB device is a storage device, the user is prompted to enter a password and jumps to step S3 ;

[0030] S3: The user enters a preset password;

[0031] S4: The computer authenticates the password input by the user. If the authentication is passed, the USB device is allowed to access data to the computer; if the authentication fails, the USB device is not allowed...

Abstract

The invention discloses a USB (universal serial bus) access control method based on passwords. The method comprises the following steps that S1, a user uses USB equipment for connecting a computer USB interface; S2, a computer judges USB equipment, if the connected USB equipment is storage equipment, the computer reminds the user to input the passwords, and if the connected USB equipment is non-storage equipment, the connection is directly realized with the computer without the need of password input; S3, the user inputs the preset passwords; S4, the computer carries out authentication on the passwords input by the user. The USB access control method has the advantages that the USB access passwords can be set for protecting internal data of the computer, and the leakage of important information is prevented.

Description

technical field [0001] The invention relates to a password-based USB access control method. Background technique [0002] With the popularity of computers, more and more important information is stored in computers. Many people's personal privacy, company's business secrets, and important government documents are all stored in computers. Once these information are illegally copied out of the computer, it will cause huge losses to the legal possession of the information. The USB storage device (U disk, mobile hard disk, USB recording device, etc.) can provide convenience for the majority of users to transmit information, but it is also the main way for information leakage. [0003] Traditional computers cannot identify USB devices, and cannot judge the type of USB devices. If disabled, all USB devices will be unavailable (including non-storage devices such as USB keyboards and mice). And if the use of the USB interface is prohibited, the convenience of the USB storage devi...
