The invention has convenient operation, can use all the peripherals only by inserting the USB key, and can disable all the peripherals by pulling out the USB key.
Description
[technical field]
The present invention relates to the control of authority technology of computer equipment, relate in particular to a kind of locking means and locking device of input peripheral.
[background technology]
When using computer equipment, run under some specific environment for use, only hope the situation that some specific crowd operates machines through regular meeting.Existing a solution is that to block with hardware be main, such as adding a lock, or directly shelters from, and does not allow to use.The existing software solution, main similar a kind of USB interface lock based on double-USB key apparatus mainly is to pin the visit of USB to movable storage device.
Can find out that two kinds of scheme applicable surfaces of the prior art are less, and software solution can only limit the read-write of USB to movable storage device.And need two usb keys to accomplish.Can't limit and operate self-defining USB device and USB that some are special.Its objective is to guarantee that data can not reveal, and can't realize rights management computer may command peripheral hardware.
[summary of the invention]
The present invention provides a kind of locking means and locking device of input peripheral, can carry out rights management to all kinds of PC equipment peripheral hardwares.
The locking device of input peripheral provided by the invention comprises:
The usb key device is used to store one or more usb keys;
Add tripper, be used to monitor USB interface and whether insert said usb key device and poll scanning and discern current input peripheral, if do not insert said usb key device; Then current said input peripheral is locked; If inserted said usb key device, then obtain said usb key, judge whether said usb key and the operating strategy that prestores mate; If coupling is then deciphered said input peripheral.
The locking means of input peripheral provided by the invention comprises step:
Poll scanning is also discerned current input peripheral;
Monitor USB interface and whether insert the usb key device; If do not insert, then said input peripheral locked, if insert; Then obtain usb key from said usb key device; Judge whether said usb key and the operating strategy that prestores mate, if coupling is then deciphered said input peripheral.
The present invention adds the rights management of release through usb key to input peripheral, has realized under the specific occasions, only allows the specific people who holds key of a part to operate machines.The present invention is easy to operate, only needs to insert usb key and can use all peripheral hardwares, extracts usb key and can forbid all peripheral hardwares.In addition, can come to change flexibly the forbidding strategy of USB peripheral hardware through the editorial management strategy.Simultaneously, the present invention adds the pattern that software combines through hardware, and good confidentiality can effectively be reached the purpose of forbidding.
[description of drawings]
Fig. 1 is the process flow diagram of the locking means of input peripheral of the present invention;
Fig. 2 is the theory diagram of the locking device of input peripheral of the present invention.
[embodiment]
It is cheaply a kind of that the present invention provides, and flexibly, can manage (comprising input peripheral equipment such as touching frame, mouse, keyboard) to all kinds of PC equipment peripheral hardwares, forbids it computer is operated input.The usb key device has been installed, through reading usb key, and has been verified, just can untie the restriction of USB peripheral hardware through this locality or network.
Fig. 1 is the process flow diagram of the locking means of input peripheral of the present invention, and is as shown in the figure: the present invention can and discern current input peripheral (S100) in the autopolling scanning of target device start back; Whether the USB interface on the intercept target equipment inserts usb key device (S101); If do not insert, then the input peripheral to target device locks (S102), if insert; Then obtain usb key (S103) from said usb key device; Judge whether said usb key and the operating strategy that prestores mate (S104), if coupling is then deciphered (S105) to said input peripheral.As an embodiment, the locking and de-locking process of target device can not got rid of the means that provide in other prior aries yet and realize through the call back function realization certainly, repeat no more at this.
It is worthy of note that the process whether step S104 checking matees can be carried out in this locality, also can handle through network remote.In addition,, when operating strategy changes or increases new input equipment, new input equipment is carried out poll, guarantee that increasing input equipment newly conforms to operating strategy as a preferred embodiment.
As further improvement to such scheme; In order to make applicable surface of the present invention wider, the present invention also provides the scheme of the USB memory device being carried out the authority restriction, and process is following: whether intercept target equipment is inserted into the USB memory storage; If there is the USB memory device; Then when not inserting the USB locking device, through revising registration table said USB device is locked, when inserting the USB locking device; If usb key and the operating strategy coupling that prestores are then deciphered said USB memory storage through revising said registration table.
As an embodiment; The operating strategy of mentioning among the present invention that prestores can be stored in the encrypt file of predetermined format; The generative process of encrypt file can be through following mode: store a special key in advance; Such as " sdafcfsa ", through this key operating strategy corresponding strategy file is encrypted, generate encrypt file.Therefore before reading operating strategy, at first encrypt file is deciphered at every turn.As an embodiment, can with encrypt file after the management end management is good, be updated on each target device.
The present invention also provides a kind of locking device of input peripheral, and is as shown in Figure 2, and this locking device comprises the usb key device and adds tripper.
The usb key device stores one or more usb keys; And have the USB interface that is connected with target device, add tripper monitoring USB interface and whether insert said usb key device and poll scanning and discern current input peripheral, if do not insert said usb key device; Then current said input peripheral is locked; If inserted said usb key device, then obtain said usb key, judge whether said usb key and the operating strategy that prestores mate; If coupling is then deciphered said input peripheral.
Equally, in order to enlarge applicable surface of the present invention, as a preferred embodiment; Add tripper and can also monitor whether there is the USB memory storage, if exist, then when not inserting said USB locking device; Through revising registration table said USB device is locked; When inserting said USB locking device, if said usb key and the operating strategy coupling that prestores are then deciphered said USB memory storage through revising said registration table.
As an embodiment,, then add tripper and judging said usb key and the operating strategy that prestores are deciphered the encrypt file of said predetermined format earlier before whether mating if the operating strategy that prestores is stored in the encrypt file of predetermined format.
The above embodiment has only expressed several kinds of embodiments of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to claim of the present invention.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the present invention's design, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with accompanying claims.
