In a preferred embodiment of the present invention, described step 102 can comprise following sub-step:

Sub-step S11, described server side is searched risk class corresponding to described hardware attributes information in preset risk class storehouse;

Sub-step S12, described server side is searched the detection rule that described risk class is corresponding in preset detection rule base.

In embodiments of the present invention, risk class storehouse can be directly fed back or carried out the result that detection trusty is added up afterwards by a large amount of collection users, and, the hardware attributes information of the movable storage device of asking for to each manufacturer and corresponding detection information creating, detect regular foundation as Dynamic Selection in embodiments of the present invention.Particularly, risk class is hardware attributes information and the common comprehensive evaluation out of detection information of movable storage device, if such as the hardware attributes information of the movable storage device of A type is found to think that it is very risky in its detection information in risk class storehouse, the movable storage device risk class of A type just can divide high-risk grade into so.

It should be noted that, the embodiment of the present invention is not construed as limiting for the dividing mode of movable storage device risk class, for example, can only according to the purchase IP address of movable storage device, divide risk class, if buying the IP address of movable storage device, discovery user is considered to buy at certain the suspicious IP region that risk is larger, the possibility that buys so problematic movable storage device in this IP region is very high, buy risk larger, can directly determine that the risk class of this movable storage device is doubtful shrink.

Step 103, described server side adopts described detection rule to initiate accessing the detection of the movable storage device of described client-side, obtains the testing result of described movable storage device;

In a preferred embodiment of the present invention, when described risk class is high-risk grade, corresponding detection rule can be result mapping ruler,

Described step 103 can comprise following sub-step:

Sub-step S21, described server side adopts described result mapping ruler to extract the hardware attributes information of the movable storage device of the described client-side of access;

Sub-step S22, described server side is searched testing result corresponding to described hardware attributes information in preset mapping (enum) data table.

In specific implementation, if movable storage device is confirmed as high-risk grade, illustrate that it is product inferior that this movable storage device is almost identified as, may be greatly for example a shrink equipment, in order saving time, to detect so the time of movable storage device, can directly to determine that this movable storage device is shrink dish.

Shrink dish also claims " dilatation dish ", " upgrading dish ", refer to that illegal manufacturer is used a kind of software of volume production instrument, movable storage device capacity is marked much larger than its actual capacity, means with swindle consumer are reaped staggering profits, when the actual capacity of movable storage device be less than or equal to its nominal 90% time, be identified as the shrink dish that has quality problems.

Shrink dish actual capacity is much smaller than mark capacity, in use, shrink coils that not only read or write speed is super slow, and can there is very soon insufficient memory, in addition, be written to the file in shrink dish, surpass the part of actual capacity, cannot normally be read and be used, can be brought the troubles such as a series of obliterated datas, work delay to user like this.So a kind of good movable storage device detection method is most important for user.

In specific implementation, owing to needing to write and reading out data in the process detecting in mobile storage, therefore, before movable storage device is detected, can capsule information be backed up first reminding user.Starting to carry out after the detection of movable storage device, the progress that can use mode reminding user movable storage devices such as detecting progress bar to detect, and reminding user avoids extracting movable storage device, prevents the loss of data.

In another kind of preferred embodiment of the present invention, when described risk class is risk grade, corresponding detection rule can be integrity rule;

Sub-step S31, described server side adopts described integrity rule to detect the request that sends the storage space that detects described movable storage device to described client-side;

Sub-step S32, described server side writes test data at the storage space of described movable storage device; The size of described test data is nominal capacity;

Sub-step S33, described server side reads the first data of described movable storage device;

Sub-step S34, described server side compares described test data and described the first data;

Sub-step S35, when the described test data of described movable storage device and the data of described the first data consistent are greater than the first predetermined threshold value, described server side obtains the testing result that described movable storage device is normal device;

Sub-step S36, when the described test data of described movable storage device and the data of described the first data consistent are less than the first predetermined threshold value, and while being greater than the second predetermined threshold value, described server side obtains the testing result that described movable storage device is unknown device;

Sub-step S37, when the described test data of described movable storage device and the data of described the first data consistent are less than the second predetermined threshold value, and while being greater than the 3rd predetermined threshold value, described server side obtains the testing result that described movable storage device is doubtful shrink equipment;

Sub-step S38, when the described test data of described movable storage device and the data of described the first data consistent are less than the 3rd predetermined threshold value, described server side obtains the testing result that described movable storage device is shrink equipment.

In specific implementation, if movable storage device is confirmed as risk grade, this movable storage device is described there is a strong possibility to be a shrink dish, because it is that the possibility of product inferior is larger, in order more to determine that whether this movable storage device is qualified product, can adopt completeness check algorithm to go to carry out strict verification.

Particularly, can deposit to this movable storage device the data of mark amount of capacity in, for example the mark capacity of movable storage device is the data that 2G just writes 2G, again the data of this 2G are read out, check again whether the data that write and read change, specifically can, with reference to the flow chart of steps of the of the present invention a kind of movable storage device integrity detection shown in Fig. 2, comprise the steps:

Step 1: file A is written on the movable storage device of 2G;

Step 2: by file A RNTO file B on the movable storage device of 2G;

Step 3: file B is read on hard disk from the movable storage device of 2G;

Step 4: whether comparison document A equate with file B, if so, movable storage device is normal movable storage device, if not, movable storage device is shrink dish.

It should be noted that, the memory capacity of movable storage device is generally 2G, 4G, 8G, 16G ... 2 ⁿg, increases progressively with the form of index, based on this feature, can detect fast more soon the actual capacity of movable storage device, specifically, can be by 2G, 4G, 8G, 16G ... 2 ⁿthe data of G size successively join in movable storage device, and for example, if the physical memory space of movable storage device is 2G, but its nominal capacity is but 16G, if directly the data of 16G are write, the time of expending is long.And the exponential increasing feature of storage space based on movable storage device, the data that can first add 2G, if data do not change, continue again to add the data of 4G, if will find that change has occurred data while adding the data of 4G, just can judge that movable storage device is the equipment shrinking, be a shrink dish.If determined that movable storage device is shrink dish, do not need so to add the data of nominal capacity just can detect the actual capacity of movable storage device, detect the required time will greatly reduce.

In another kind of preferred embodiment of the present invention, when described risk class is low risk level, corresponding detection can be data point rule;

Sub-step S41, described server side adopts described data point rule detection to described client-side, to send the request of the storage space that detects described movable storage device;

Sub-step S42, described server side obtains each sets of sectors of the storage space of described movable storage device;

Sub-step S43, described server side judges whether each sets of sectors of the storage space of described movable storage device is normal sets of sectors;

Sub-step S44, described server side calculates the ratio of normal sets of sectors in the storage space of described movable storage device;

Sub-step S45, by described normal sets of sectors, ratio and the preset ratio in the storage space of movable storage device compares described server side; Described preset ratio comprises the first preset ratio, the second preset ratio, and the 3rd preset ratio;

Sub-step S46, when the ratio of the normal sets of sectors of the storage space of described movable storage device surpasses the first preset ratio, described server side obtains the testing result that described movable storage device is normal device;

Sub-step S47, when the ratio of the normal sets of sectors of the storage space of described movable storage device is less than the first preset ratio, and while being greater than the second preset ratio, described server side obtains the testing result that described movable storage device is unknown shrink equipment;

Sub-step S48, when the ratio of the normal sets of sectors of the storage space of described movable storage device is less than the second preset ratio, and while being greater than the 3rd preset ratio, described server side obtains the testing result that described movable storage device is doubtful shrink equipment;

Sub-step S49, when the ratio of the normal sets of sectors of the storage space of described movable storage device is less than the 3rd preset ratio, described server side obtains the testing result that described movable storage device is shrink equipment.

In specific implementation, sector is the physical memory cell of the disk minimum in movable storage device, and the size of a general sector is 512 bytes.For example, the movable storage device of a 2G, refer to that the storage space that all sectors in movable storage device form has 2G, for example, file is stored on USB flash disk, is actually file allocation is stored to comprising on the storage space of a plurality of sectors, such as, the film of a 300MB, is placed on USB flash disk, and being in fact has a lot of sectors being responsible for storage data.

For the movable storage device of a nG, can use following equation expression, wherein n is positive number:

Size=nG=n*1024*1024*1024 byte of each sector of number * of sector

Therefore, check whether shrink dish of a movable storage device, the most essential principle, confirm exactly whether sector number in described movable storage device meets equation above, the shrink of shrink dish in fact, disappearance be the number of sector, for a shrink dish, illustrate that the number of sectors in its physical memory space is inadequate, even if be for example known as the capacity of movable storage device, have 2G, but the capacity of the data of its actual storage is less than 2G certainly.

Particularly, the nominal capacity as the quantity of sector in the sets of sectors of detected object by movable storage device determines, for example, if the USB flash disk of 1G, the USB flash disk of 4G 100 sectors can be set as detected object, if can arrange 400 sectors as detected object.

In specific implementation, because the position that writes other sectors beyond the sets of sectors of random data and the sector in described sets of sectors is common factor not, therefore in normal situation, the random data writing and test data are not occured simultaneously, but, in the situation that movable storage device is shrink dish, the capacity of the random data writing is greater than for storing the capacity of the sector of random data, therefore random data will take the position of other sectors, for example take the position of described sets of sectors, random data will part coverage test data like this, to test data, cause interference, cause the second data and the test data that read inconsistent, also therefore proved that described sets of sectors is abnormal sets of sectors.

Particularly, a movable storage device can have a lot of sectors according to its capacity, can from the larger sector of these quantity, randomly draw several sectors and form a sets of sectors, in whole movable storage device, can there be several sets of sectors, the distribution on a rough average of these several sets of sectors, can cover between the sector null of whole movable storage device, but discontinuous between these sets of sectors, do not occur simultaneously, for example, whole movable storage device has 10000 sectors, certain sets of sectors may comprise 100 sectors, the distribution of these 100 sectors in 10000 sectors of whole movable storage device can be respectively 1-20, 1000-1040, the 2000th to 2020, the 8000th to 8020.

In specific implementation, random data can be random code, and do not occur simultaneously in other sectors beyond described sets of sectors and the position of the sector in described sets of sectors, and other sectors beyond described sets of sectors are several sectors of randomly drawing.

Because can carry out reading and writing data in the testing process of movable storage device, the data that write or read can cause the test data and the primary data that in the storage space of described movable storage device, write different, therefore user test data should be reverted to the primary data of movable storage device, so that can normally use movable storage device.

In a preferred embodiment of the present invention, before the step of the second data in reading sets of sectors, also comprise following sub-step:

After exiting described movable storage device, again access described movable storage device.

In practice, some illegal manufacturer, for some testing tools, has set up caching mechanism in movable storage device, and can affecting testing tool, to detect movable storage device be shrink equipment.And first exit by adopting the secondary detection mode that movable storage device accesses again, and can more accurately calculate the actual capacity of movable storage device, the accuracy of detection also will greatly improve.

It should be noted that, sets of sectors quantity can be determined according to the size of movable storage device, the test data writing also can freely be selected according to actual conditions, for example, if want more accurately to detect the storage space of movable storage device, can in sector, write larger data, in addition, can also on the basis of definite sets of sectors, further append new sector in embodiments of the present invention, or increasing more test data detects, with this, carry out more strictly to detect the physical memory space of movable storage device, the present invention is not restricted this.

In another kind of preferred embodiment of the present invention, if described server obtains the testing result that described movable storage device is normal device, described server side adopts described detection rule to initiate accessing the detection of the movable storage device of described client-side, and the step that obtains the testing result of described movable storage device can also comprise following sub-step:

Sub-step S53, when the reading speed of described mobile storage is less than pre-set velocity threshold value, described server side obtains the testing result that described movable storage device is aging equipment inferior.

In specific implementation, the testing result that described movable storage device is normal device if generate, can also further judge whether this movable storage device is inferior aging equipment by detecting the read or write speed of movable storage device.Although some movable storage device actual capacity is nominal capacity, be likely inferior or aging equipment, therefore its actual read or write speed is slower.Product inferior may be because producer utilizes some bad chips, master control inferior to manufacture movable storage device, for example, or some make failed memory device (having bad piece), aging equipment may be to place to cause for a long time aging movable storage device.

At present, read or write speed can judge whether movable storage device is inferior or aging, and reading speed account form can adopt to calculate and write certain known file specifically, and is divided by and can obtains the reading speed of this movable storage device with the time of reading this document.Wherein, the account form of writing speed and the account form of reading speed are similar.

Step 104, described server side returns to the testing result of described movable storage device.

Can be for final testing result in actual applications, return to risk description more intuitively of user.When according to different risk class, adopt different detection rule detection complete after, for example, if when USB flash disk is finally identified shrink equipment, can return to similar " your USB flash disk for shrink " or " with your USB flash disk USB flash disk 90% of the same type for shrinking ".

A kind of example as the concrete application of the embodiment of the present invention, because can carry out reading and writing data in the testing process of movable storage device, the data that write or read can cause the test data and the primary data that in the storage space of described movable storage device, write different, therefore user test data should be reverted to the primary data of movable storage device, so that can normally use movable storage device.
