Abstract
In the premise that use of non-secured data in the memory of a personal computer is not affected, and to solve the technical problem that the verification code for accessing authority verification of secured data is subject to declassification so as to provide a safe memory space for the secured data, the utility model provides a personal computer which can perform access control of memory spaces. The personal computer comprises a central processor, which is connected with input devices, output devices and a plurality of sections of memory media composed of one or more memories. The utility model is characterized in that the computer also comprises a device with a verification code, which is separate from the personal computer body in normal time; the device with the verification code can be plugged into an appointed interface of the personal computer body; the computer is also provided with a normally-off change-over switch which is series connected between a section of memory media and the central processor; the control end of the change-over switch is connected with the central processor. When the device with the verification code is plugged into the appointed interface, the change-over switch turns on only when the verification code is tested and verified.
Description
Technical field
The utility model relate to can to storage space conduct interviews control PC.
Background technology
The data storage of PC (personal computer) is in the storage medium of storer.A PC, its central processing unit can connect a plurality of storeies.Generally speaking, storage space on the storer allows to be visited by Any user, if but the data storage that needs to maintain secrecy is arranged in the storer of PC, then each is attempted to visit the request of private data, all should carry out strict authority audit, to can't being refused, to guarantee that private data is not revealed by the request of access of authentication.Secrecy provision commonly used at present is that when the user sent request of access, system ejected the identifying code input frame, the input equipment that the user carries by PC (for example keyboard) input validation sign indicating number, this identifying code is checked by system, has only identifying code to coincide, and just allows private data accessed.The defective of this secrecy provision is that its identifying code is used the method for exhaustion easily and attempts one by one and cracked, have multiple special decryption software now on the internet at this secrecy provision, during running software, automatically attempt identifying code according to the order of setting, coincide the visit that just is opened of the space of storage security data until identifying code.As seen, this secrecy provision performs practically no function in face of decryption software, and identifying code just is cracked easily.
The utility model content
The purpose of this utility model is under the prerequisite of the normal use of unclassified data in not influencing the PC storer, solution is used for the technical matters of the identifying code easy crack of private data access authority verification, thereby the storage space of one section safety is provided for private data.
Be head it off, the utility model provide can to storage space conduct interviews control PC, comprise central processing unit, central processing unit connects input equipment, output device and the multistage storage medium of forming by one or more storeies, it is characterized in that, the equipment that also comprises the band identifying code that separates with this machine of PC at ordinary times, the equipment of band identifying code can insert the designated port of this machine of PC, the change-over switch that also is provided with normal off is serially connected between one section storage medium and the central processing unit, the control termination central processing unit of change-over switch, when the equipment of described band identifying code inserts the designated port of this machine of PC, it is just closed to have only identifying code to be verified by, change-over switch.
The change-over switch that the utility model is provided with normal off is serially connected between one section storage medium and the central processing unit, and making at ordinary times can not be accessed corresponding to the storage space of this section storage medium.The input equipment input validation sign indicating number that secrecy provision in the background technology allows the user directly to carry by computing machine; And the utility model is stored in identifying code to be verified in the equipment that can insert this machine of PC designated port, the user can only allow PC read identifying code in the equipment of described band identifying code by the mode that the equipment of this band identifying code is inserted this machine of PC, have only identifying code be verified by, the change-over switch that is serially connected between this section storage medium and the central processing unit is just closed, thereby be communicated with the circuit between this section storage medium and the central processing unit, this moment, the user just can visit the storage space corresponding to this section storage medium.This just makes that the people of the equipment of not holding this band identifying code can't the input validation sign indicating number, also just can't visit the private data that is stored in this section storage space, has solved the technical matters of identifying code easy crack.Because the utility model has only the control that the visit of a part of storage medium is subjected to change-over switch, the user who does not hold the equipment of described band identifying code still can normally visit other storage space, and unclassified data are operated.
Description of drawings
Accompanying drawing is the utility model schematic diagram.
Embodiment
Can to storage space conduct interviews control PC, comprise central processing unit, central processing unit connects keyboard, display and a plurality of storer, the equipment that also comprises the band identifying code that separates with this machine of PC at ordinary times, the equipment of band identifying code can insert the designated port (is example with the USB port) of this machine of PC, the change-over switch that also is provided with normal off is serially connected between one of them storer and the central processing unit, the control termination central processing unit of change-over switch.
When the equipment of described band identifying code inserts the USB port of this machine of PC, CPU (central processing unit) reads identifying code from the equipment of described band identifying code and verifies, after checking is passed through, the closed change-over switch of central processing unit, make the storage medium of this storer and the circuit communication between the central processing unit, the user just can pass through keyboard typing private data, or checks private data by display.
After the change-over switch closure, if the designated port of the equipment of described band identifying code and this machine of PC disconnects, change-over switch just disconnects again, in order to avoid late comer's unauthorized access private data.
Claims (3)
- Can to storage space conduct interviews control PC, comprise central processing unit, central processing unit connects input equipment, output device and the multistage storage medium of forming by one or more storeies, it is characterized in that, the equipment that also comprises the band identifying code that separates with this machine of PC at ordinary times, the equipment of band identifying code can insert the designated port of this machine of PC, the change-over switch that also is provided with normal off is serially connected between one section storage medium and the central processing unit, the control termination central processing unit of change-over switch, when the equipment of described band identifying code inserts the designated port of this machine of PC, it is just closed to have only identifying code to be verified by, change-over switch.
- According to claim 1 can be to the conduct interviews PC of control of storage space, after the change-over switch closure, if the designated port of the equipment of described band identifying code and this machine of PC disconnects, change-over switch is disconnection again just.
- According to claim 1 can to storage space conduct interviews control PC, described designated port is a USB port.
