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
The present invention relates to a kind of USB access control method based on password.
Background technology
Along with popularizing of computer, more and more important information is all saved in a computer.The individual privacy of many people, the trade secret of company, the vital document of government is all kept in computer, and these information, once be illegally duplicated out computer, will have information legal and cause huge loss.And USB storage device (USB flash disk, portable hard drive, USB recording device etc.) can provide conveniently for users' transmission information, but be also the main path of information leakage simultaneously.
Traditional computer cannot identify USB device, cannot judge the classification of USB device.If forbidding, USB device will all unavailable (comprising the nonstorage devices such as USB keyboard, mouse).And if USB interface is prohibitted the use, the convenience of USB storage device is again less than performance.
Prior art adopts the unidirectional control of USB poke equipment to solve this problem.The storage medium of the unidirectional control technology of USB storage device to access computing machine controls, prevent information from being had a mind to or leaking out from movable storage device unintentionally, real user in this way can set memory device rights of using as required, but need in advance USB storage device to be inserted computer to arrange, this is concerning inconvenient user, and this method is also immature, there is certain defect.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of USB access control method based on password is provided, USB access code can be set, the data of computer inside are protected, prevent important information from revealing.
The object of the invention is to be achieved through the following technical solutions: a kind of USB access control method based on password, it comprises the following steps:
S1: user uses USB device to connect computer USB interface;
S2: computer judges USB device, if the USB device connected is nonstorage device, does not then need input password to be directly connected with computer; If the USB device connected is memory device, then points out user to input password, jump to step S3;
S3: user inputs default password;
S4: computer carries out authentication to the password that user inputs, if authentication is passed through, then allows USB device to carry out data access to computer; If authentication is not passed through, then USB device is not allowed to carry out data access to computer.
Described computer comprises following sub-step to the step that USB device judges:
Described password comprises numerical ciphers, graphical passwords.
Described password passes through input through keyboard.
Described password is inputted by touch-screen.
Described password is equipment moving behavior password.
Described password is finger-print cipher.
Described USB storage device comprises USB flash disk, portable hard drive, USB recording device.
Described non-USB storage device is usb mouse, USB interface keyboard.
It also comprises the step of a Modify password, need first input original password during Modify password, by inputting new password after checking.
The invention has the beneficial effects as follows:
(1) be provided with USB access code, need correct input password could access computer internal data, protect the information always in computer, prevent the leakage of information.
(2) USB device is identified to only have and just carry out code authentication when connecting USB storage device, not only convenient for users to use the but also information protected in computer.
(3) various ways supported by password, improves the safe class of protection, better protects the information in computer.
Accompanying drawing explanation
Fig. 1 is process flow diagram of the present invention;
Fig. 2 is code authentication process flow diagram of the present invention.
Embodiment
Below in conjunction with accompanying drawing, technical scheme of the present invention is described in further detail, but protection scope of the present invention is not limited to the following stated.
As shown in Figure 1, a kind of USB access control method based on password, it comprises the following steps:
S1: user uses USB device to connect computer USB interface;
S2: computer judges USB device, if the USB device connected is nonstorage device, does not then need input password to be directly connected with computer; If the USB device connected is memory device, then points out user to input password, jump to step S3;
S3: user inputs default password;
S4: computer carries out authentication to the password that user inputs, if authentication is passed through, then allows USB device to carry out data access to computer; If authentication is not passed through, then USB device is not allowed to carry out data access to computer.
Described password comprises numerical ciphers, graphical passwords, and by the touch-screen that memory device carries, user can draw specific figure, is sampled by graph data, forms graphical passwords.
Described password is by input through keyboard, and described password inputs by touch-screen.By keyboard that memory device carries or touch-screen as input equipment, input user-defined password.
Described password is equipment moving behavior password, for built-in gravity sensor, motion sensor, gyroscope etc., possesses the equipment that motor behavior detects, can by carrying out the rocking of specific direction to equipment, overturn and produce specific motor behavior, these exercise data acquisitions are got off, and be sampled to specific movement locus, and as code data.
Described password is finger-print cipher, sets the equipment of device with fingerprint, can be scanned the fingerprint of user, and used as password by its characteristic parameter by fingerprint equipment.
Described USB storage device comprises USB flash disk, portable hard drive, USB recording device.
Described non-USB storage device is usb mouse, USB interface keyboard.
Described password can be modified, and need first input original password during Modify password, by inputting new password after checking.
The above is only the preferred embodiment of the present invention, be to be understood that the present invention is not limited to the form disclosed by this paper, should not regard the eliminating to other embodiments as, and can be used for other combinations various, amendment and environment, and can in contemplated scope described herein, changed by the technology of above-mentioned instruction or association area or knowledge.And the change that those skilled in the art carry out and change do not depart from the spirit and scope of the present invention, then all should in the protection domain of claims of the present invention.
