Code technology and planar bar code technology, two dimensional code optical recognition is as current the most widely used tag identification technologies, really
Real, it has rapidly captured market with extremely cheap manufacturing cost.But just because of its technology content is too low, it is also with regard to only
The reliability of its entrained information can be ensured in a short time.Its limitation clearly, mainly due to two dimensional code discomfort
Cooperation protects stored medium for needs for a long time.Bar codes technique equally also has drawbacks described above.
The normal process for reading information using Radio Frequency Identification Technology in the prior art is as follows, obtains RF tag first
UID recycles the UID information of RF tag to search out the file information associated with it in the database later, but this text
The acquisition process safety of part information is insufficient, is easy illegally to be obtained by other people.
Summary of the invention
The technical problem to be solved by the present invention is how to improve the safety of the file information acquisition in file management system
Property.
The solution that the present invention solves its technical problem is:
A kind of setting read method of the file information, comprising the following steps:
Step 1, input file information and RF tag UID in the database；
Step 2, cryptographic operation is carried out to the file information using SHA-1 hash algorithm, obtained corresponding to the file information
Cryptographic Hash；
Step 3, in the database that RF tag UID is associated with cryptographic Hash corresponding to the file information；
Step 4, the RF tag UID of file is obtained using radio-frequency card reader；
Step 5, using RF tag UID, cryptographic Hash associated with RF tag UID is found in the database, to Kazakhstan
Uncommon value is decoded operation and obtains corresponding the file information.
As a further improvement of the above technical scheme, the RF tag UID includes information code and secret key code, difference
Secret key code and different Encryption Algorithm it is corresponding, the information code is source code to be added by Encryption Algorithm corresponding to secret key code
It is obtained after close, enables source code associated with the cryptographic Hash of the file information in the database, RF tag UID is obtained in step 5
Operation is decrypted to information code according to Encryption Algorithm corresponding to secret key code afterwards and obtains source code.
As a further improvement of the above technical scheme, after the step 3, further include step 3a, establish classification tree mould
Type classifies to source code all in database using classification-tree method, all source codes is divided into multiple code characters；
After the source code for obtaining RF tag UID in step 5, the source code is input in classification-tree method, it is fixed
After position goes out the affiliated code character of source code, then cryptographic Hash associated with RF tag UID is found, behaviour is decoded to cryptographic Hash
Obtain corresponding the file information.
As a further improvement of the above technical scheme, the source code includes several verification code bits, the check code
The quantity of position is corresponding with the quantity of classification-tree method level, and each verification code bit is respectively as each in classification-tree method
The variable parameter of hierarchy node.
The beneficial effects of the present invention are: the present invention carries out each the file information inputted by SHA-1 hash algorithm
Cryptographic operation obtains the cryptographic Hash of each the file information, then the cryptographic Hash of each the file information is associated with RF tag UID
Get up, can guarantee the safety of information when reading the file information.
Detailed description of the invention
