In certain embodiments, come into force under the condition that security strategy sets user.
In certain embodiments, change under the condition that security strategy sets user.
In certain embodiments, hardware identification module is hardware circuit module, connecting interface module and controlled in wireless module, and obtains hardware identity information by usb protocol.
In certain embodiments, hardware identification module is built in and stores in module, storer or the storage area of a priority access, store the program code that one section of energy performs in outside fetch equipment, described formula is communicated with controlled in wireless module by interface module, and the hardware identity information of acquisition is transferred to external remote control equipment by controlled in wireless module; Set up the mapping table of hardware information and exterior read-write equipment at outside remote control equipment and select to arrange safe class and security strategy according to user; According to the setting of user, safe USB disk performs corresponding security strategy to outside fetch equipment.
In certain embodiments, user can revise safe class or security strategy.
The present invention by arranging the identification module (hardware identification module) of the hardware identity information for reading exterior read-write equipment in flash disk, and this hardware identity information is sent to the handheld terminal of user, set up the mapping of exterior read-write equipment and hardware identity information at handheld terminal record and arrange according to user and set up safe class and corresponding security strategy, this safe class and policy store, in handheld terminal or flash disk, make handheld terminal or flash disk possess the ability identifying exterior read-write equipment.According to the setting of user, corresponding security strategy or safe class are performed to exterior read-write equipment, thus realize the access control to flash disk, and reduce bothering user as far as possible.
Due to flash disk limited space, do man-machine interaction more difficult on flash disk, so in the present invention, be sent on handheld terminal through controlled in wireless module by the hardware information of acquisition and process, user formulates security strategy at handheld terminal.
Previous security strategy refers to about the manifestation mode that flash disk access control and super distance are reminded.Here the formulation of security strategy is generally according to concrete environment for use, such as, under public environment, needs each all by handheld terminal mandate; Under security context, do not need to authorize again, so just do not need handheld terminal to participate in authentication yet.
Below enumerate several security strategy:
1. flash disk connect exterior read-write equipment time by external remote control equipment automatically to access authorization; This situation is applicable to use the situations such as the Office PC of computer or Mon-Fri period at home, and the level of security that this situation is arranged is lower, can automatic authorization;
2. when flash disk connects exterior read-write equipment, always require that user is manually to access authorization; This situation uses flash disk under being applicable to foreign environment, for safety, all needs user's manual authorisation at every turn;
3. flash disk is after being connected to exterior read-write equipment, if do not read and write behavior within a certain period of time, again requires access authorization; This situation is applicable to flash disk, and a period of time does not use at home, when reusing, needs user's manual authorisation again;
4., after the distance of flash disk and external remote control equipment exceeds preset value, do not report to the police; This situation be applicable to by flash disk by means of give other people use elsewhere time, can be arranged in a period of time and not report to the police;
5., after the distance of flash disk and external remote control equipment exceeds preset value, report to the police.
6., after the distance of flash disk and external remote control equipment exceeds preset value, again require access authorization;
7. the distance of flash disk and external remote control equipment is in preset value again, and external remote control equipment is automatically to access authorization.
Security strategy is formulated according to time, event etc., and around the executive mode of access control and over-distance alarm.Because Time And Event is not quite similar, in esse security strategy is too numerous to enumerate, just lists above-mentioned 7 kinds of strategies herein, but does not limit with above-mentioned 7 kinds of strategies.
Previous security grade refers to the set of security strategy, is the security strategy collection chosen in advance, user-friendly.Such as, safe class has:
1. security strategy 1+ security strategy 4
2. security strategy 1+ security strategy 3+ security strategy 4+ security strategy 6+ security strategy 7
3. security strategy 2+ security strategy 5+ security strategy 6
Bothering of above-mentioned safe class 1 couple of user is minimum, and such as, flash disk is connected to the exterior read-write equipment under home environment by applicable user; Bothering of above-mentioned safe class 2 couples of users is relatively less, and such as, flash disk is connected to the exterior read-write equipment under office environment by applicable user; Bothering of above-mentioned safe class 3 couples of users is relatively many, and such as, flash disk is connected to the exterior read-write equipment under foreign environment by applicable user.As above, user can according to own situation, choose reasonable safe class or defined security level or security strategy, flash disk of the present invention and its implementation can under the prerequisites of security ensureing flash disk, reduce number of operations or the alarm frequency to greatest extent, reduce bothering user, obtain friendly experience, reached the object of the present invention.
The above is only preferred embodiment of the present invention, not does any pro forma restriction to the present invention.Any those skilled in the art, when not departing from technical solution of the present invention scope, can utilize the technology contents of above-mentioned announcement to make multiple possible variation and modification to technical solution of the present invention, or being revised as the Equivalent embodiments of equivalent variations.Therefore, every content not departing from technical solution of the present invention, according to essence of the present invention to any simple modification made for any of the above embodiments, equivalent variations and modification, all belongs to the protection domain of technical solution of the present invention.
