Embodiment
Basic thought of the present invention is: identify according to the active user and generate the document bar code; Based on the document bar code stores document that generates.
For making the purpose, technical solutions and advantages of the present invention clearer, by the following examples and with reference to accompanying drawing, the present invention is described in more detail.
As shown in Figure 2, a kind of electronic barcode method of definite uniqueness of electronic documents by using, this method may further comprise the steps:
Here, the document bar code unique identification active user corresponding with this current user ID.
Here, the document of this storage is: corresponding to the document of the active user of this current user ID storage.
At step 101, generate the document bar code and comprise two kinds of situations, first kind of situation identifies generation document bar code according to the active user, thereby can be accurate to its pairing different user with the different document bar code is unique, so that follow-uply distinguish out the document that different user is stored; Second kind of situation on the basis of active user sign, further increases the current time in system to generate the document bar code.That is to say, generate the document bar code according to active user's sign and current time in system, thereby, can not only be on unique basis that is accurate to its pairing different user with the different document bar code, and, can be accurate to the document bar code different system time of same user of unique correspondence so that follow-up according to distinguishing out the document that same user's different system time stored.
Wherein,, identify according to the active user and to generate the document bar code and further be: active user's sign is defined as the seed of first group of random number, generates first group of random number in the document bar code at first kind of situation.At second kind of situation, generate the document bar code according to the current time in system and further be: will be defined as the seed of second group of random number the current time in system, and generate second group of random number in the document bar code.
It is pointed out that document bar code of the present invention is the expansion of being done on existing EAN13 bar code basis.For instance, the first, behind 12 bar code symbols of existing EAN13 bar code, added two groups of random numbers, with the uniqueness of assurance document bar code, and every group of random number got 5.Wherein, the seed of first group of random number is to utilize the active user to identify, and is about to the seed that active user's sign is defined as first group of random number, generates first group of random number in the document bar code; The seed of second group of random number is the time of utilizing system current, is about to the seed that the current time in system is defined as second group of random number, generates second group of random number in the document bar code.The second, the 13rd of existing EAN13 bar code is displaced to the 23rd, that is: the 23rd is the check bit in the document bar code, 22 before the check bit is effective code.The computing method of check code and existing EAN13 bar code are similar, are specially: 10-MODE ((even bit sum * 3 in odd bits sum+22 effective code in 22 effective codes), 10).The 3rd, expand back 23 document barcode format and be: area number+company's numbering+item number+user ID random number+system time random number+check bit.Wherein, area number is 3, and company is numbered 4, and item number is 5, and the user ID random number is 5, and the system time random number is 5, and check bit is 1.
As shown in Figure 3, similar at the composition of the bar code symbol of document bar code of the present invention with existing EAN13 bar code, specifically comprise: comprise this six part of initial symbol, left data symbol, central seperating character, right side data symbols, check character and full stop.Wherein, the left data symbol is 6 bit digital, and the right side data symbols is 15 bit digital after having expanded two groups of random numbers, and check character is 1 bit digital.Among Fig. 3, be preamble for 6 in people's identification character 69012345678956789567892.The formation of forming each symbol in the structure at document bar code of the present invention, similar with existing EAN13 bar code, be specially: all symbols that the document bar code is formed in the structure are made up of 165 modules altogether, wherein, every bar code symbol all is made up of 7 modules, 22 bar code symbols promptly are made up of 154 modules, in the foremost of these 22 bar code symbols be respectively equipped with initial symbol and full stop backmost, respectively account for 3 modules.And left data symbol and the middle central seperating character that also has 5 modules of right side data symbols at EAN13.
At step 102, for instance, the storage document comprises following two kinds of situations, first kind of situation is based on the document bar code stores document that generates, further, not only can be to the document of new establishment, and can the document of having created be stored based on the document bar code that generates.Second kind of situation, on basis based on the document bar code stores document that generates, this storage further is: store based on the filing catalogue of current document and/or the search key of current document, that is to say, based on the document bar code that generates, these conditions of the search key of the filing catalogue of affix current document and/or current document are stored documents in the lump again.
Such as, when the user utilizes document bar code stores file, can eject dialog box on the system interface, need the user to fill in user ID; Perhaps user ID, and these conditions of search key of filing catalogue and/or current document.Wherein, user ID is to be used for producing unique document bar code, and the filing catalogue is the catalogue of document storage, and search key is the identifier of the document, and is used during for later user search.
After step 102, also comprise: the step of search file.Specifically, at first kind of situation of storage, owing to be based on the document bar code stores document of generation, and the document bar code generates by user ID again, therefore, and correspondingly, search file can for: according to active user sign, the document of retrieval active user storage.Second kind of situation at storage, owing to be based on the document bar code of generation, the filing catalogue of affix current document in the lump again, and/or these condition storage documents of the search key of current document, therefore, correspondingly, identifying according to the active user on the basis of retrieval, search file further is: according to the filing catalogue of current document, and/or the search key of current document, the document of retrieval active user storage, that is to say, according to active user sign, the filing catalogue of affix current document in the lump again, and/or these conditional information retrieval documents of the search key of current document.
Similarly, in document management, behind the storage document, document is classified, file and when searching, also can adopt the processing that is similar to retrieval, identify based on the active user document is classified, filed and searches; Perhaps identify according to the active user, these conditions of the search key of the filing catalogue of affix current document and/or current document are classified, are filed and search document in the lump again, thereby improved customer documentation efficiency of managing and accuracy greatly, made things convenient for user's routine work, living and studying simultaneously.
The above is preferred embodiment of the present invention only, is not to be used to limit protection scope of the present invention.
