Abstract

The present invention relates to the safe U disc of a kind of band checking device, USB flash disk, by verifying that device, read-write discs form, is provided with authentication module, wire guide plate in checking device, records first verification data in authentication module, and wire guide plate is connected with authentication module, and extends checking device；Being provided with contrast module, memory module, metallic channel in read-write discs, contrast module records the second checking data；When the wire guide plate of checking device inserts the metallic channel of read-write discs, wire guide plate and the contrast module contact verifying device, pass through wire guide plate, in checking device, the first verification data of authentication module transmits to contrasting module, and verify that data contrast with the second of contrast module, when first verification data and the second checking data are identical, contrast module sends unlocking command to memory module, such that it is able to the memory module of USB flash disk is written and read operation.The inventive method is advanced, science, by the present invention, improves safety, has reached to protect the purpose of USB flash disk data.

Description

A kind of safe U disc of band checking device

Technical field

The present invention relates to the safe U disc of a kind of band checking device, belong to USB flash disk safety design technical field.

Background technology

USB flash disk, full name USB flash drive, it is that a kind of miniature high power capacity without phisical drive using USB interface moves Storage product, is connected with computer by USB interface, it is achieved plug and play.Along with the universal of computer utility and storage device The expanding day of capacity, the use of movable storage device is more and more extensive, the problem thus having caused storage equipment security. And existing USB flash disk, before read-write, do not verify whether the function being legal people to use USB flash disk, often due to not encryption, appoint As long as USB flash disk is inserted computer by who just can read or revise the data inside USB flash disk, thus the data of USB flash disk are brought safely the biggest Potential safety hazard.Therefore, people are in the urgent need to a kind of safer USB flash disk.

Summary of the invention

The purpose of the present invention is aiming at the drawback that above-mentioned prior art exists, it is provided that one can improve USB flash disk safety Band checking device safe U disc.

The object of the present invention is achieved like this, the safe U disc of a kind of band checking device, it is characterized in that: described USB flash disk is by testing Card device, read-write discs form, and be provided with authentication module, wire guide plate, record the first checking in authentication module in described checking device Data, wire guide plate is connected with authentication module, and extends checking device；Be provided with in described read-write discs contrast module, memory module, Metallic channel, contrast module records the second checking data；When the wire guide plate of checking device inserts the metallic channel of read-write discs, wire guide plate With the contrast module contact of checking device, by wire guide plate, in checking device, the first verification data transmission of authentication module is to right Ratio module, and verify that data contrast with the second of contrast module, when first verification data and the second checking data are identical, Contrast module sends unlocking command to memory module, such that it is able to the memory module of USB flash disk is written and read operation, when the first checking When data differ with the second checking data, the memory module of USB flash disk is in the lock state, it is impossible to memory module is written and read behaviour Make.

Limit secondary module, in limited time module it is additionally provided with, when first verification data and second verifies data not in described comparing module Time identical, again checking device can be inserted in read-write discs and verify, set when the number of times of authentication error reaches to limit secondary module During fixed number of times, cannot be carried out verification operation in limited time in the time of module settings.

The number of times that described limit secondary module sets is as 2-10 time.

The time of described module settings in limited time is 1-10 hour.

Described read-write discs rear end is provided with suspension member hole.

The inventive method is advanced, science, by the present invention, needs to verify before using USB flash disk, i.e. checking device When wire guide plate inserts the metallic channel of read-write discs, wire guide plate and the contrast module contact of checking device, by wire guide plate, verify device The first verification data of interior authentication module transmits to contrasting module, and verifies that data contrast with the second of contrast module, when When first verification data and the second checking data are identical, contrast module sends unlocking command to memory module, such that it is able to USB flash disk Memory module be written and read operation, when first verification data with second verify data differ time, the memory module of USB flash disk is in Lock-out state, it is impossible to memory module is written and read operation, prevents disabled user the data in USB flash disk are read out or revise, Improve safety.Meanwhile, the number of times of checking is also conditional, when, after multiple authentication mistake, module starts in limited time, will set Checking can not be proceeded in the fixed time, thus improve safety, reach to protect the purpose of USB flash disk data.

Accompanying drawing explanation

Fig. 1 is the structural representation of the present invention.

In figure: 1 checking device, 2 read-write discs, 3 authentication modules, 4 wire guide plates, 5 contrast modules, 6 memory modules, 7 metallic channels, 8 suspension member holes.

Detailed description of the invention

Below in conjunction with the accompanying drawings and accompanying drawing explanation technical scheme is described in further detail.

The safe U disc of a kind of band checking device, USB flash disk, by verifying that device 1, read-write discs 2 form, is arranged in checking device 1 Authentication module 3, wire guide plate 4, record first verification data in authentication module 3, wire guide plate 4 is connected with authentication module 3, and extends Go out to verify device 1；Arranging contrast module 5, memory module 6, metallic channel 7 in read-write discs 2, contrast module 5 records second and tests Card data；When the wire guide plate 4 of checking device 1 inserts the metallic channel 7 of read-write discs 2, wire guide plate 4 and the contrast module 5 verifying device 1 Contact, by wire guide plate 4, in checking device 1, the first verification data transmission of authentication module 3 is to contrast module 5, and with contrast mould Second checking data of block 5 contrast, and when first verification data and the second checking data are identical, contrast module 5 is to storage Module 6 sends unlocking command, such that it is able to the memory module 6 of USB flash disk is written and read operation, when first verification data and second is tested When card data differ, the memory module 6 of USB flash disk is in the lock state, it is impossible to memory module 6 is written and read operation.

Further, grand in the present invention, in comparing module 5, also set up limit secondary module, in limited time module, when first verifies number According to when differing with the second checking data, again checking device 1 can be inserted in read-write discs 2 and verify, work as authentication error Number of times reach limit secondary module set number of times time, cannot be carried out verification operation in limited time in the time of module settings.Limit time mould The number of times that block sets is as 2-10 time, and the time of module settings is 1-10 hour in limited time.Meanwhile, hang for convenience or carry, this Bright, read-write discs 2 rear end arranges suspension member hole 8.
