2) security code label is taken pictures by personal user's end by the machine vision of smart machine, obtains image；
3) acquired image of taking pictures is processed by recognizer and identifies security code character string by security code tag processes software；
4) security code character string is sent to Antiforge inquiry terminal server；
5) this security code character string is carried out the true and false and distinguishes by Antiforge inquiry terminal server；
6) will distinguish that result feeds back to the smart machine possessing machine vision.
Concrete, the recognizer of the security code tag processes software in step 3) comprises the following steps:
3.1) image of security code label is obtained；
3.2) this image be sequentially carried out normalization, remove noise, file pre-treatment that image rectification, picture and text analysis, literal line separate with word；
3.3) security code feature is extracted；
3.4) in conjunction with security code character feature storehouse, security code coupling is carried out；
3.5) check whether security code mates correctly；
3.51) if extracting security code feature；
3.52) if security code matching error, then again mate once, as correct in security code coupling, then output security code character string；
3.53) if security code matching error twice, then step 3.1 is returned) reacquire the image of security code label.
Personal user can process software-driven machine vision equipment by security code and complete the acquisition to security code, and is transferred to product false proof inquiry service by the mode of instant short message or network and carries out Antiforge inquiry.
MSG is the abbreviation of Messenger, and Chinese is instant message.HTTP, i.e. HTML (Hypertext Markup Language), be the abbreviation of HyperTextTransferProtocol.In browser address bar, input web-site address when browsing webpage all start with " HTTP: // ".HTTP defines how formatted information is, how to be transmitted, and the response that server and browser are taked under various orders.
The smart machine possessing machine vision of the present invention can be smart mobile phone, is mobile machine visual apparatus, can accomplish whenever and wherever possible product to be carried out Antiforge inquiry.
The present invention is directed to query aspects and propose improved procedure, the malice inquiry for consumer is prevented by application program restriction inquiry times and charging mode.Data base, at the automatic record queries number of consumer's first time inquiry, inquiry times or query facility number, exceedes certain number of times and then takes charging mode, and this product then empties the enquiry number log of this product record after being acquired unlocking cipher.
Image (multimedia message mode), short message can also be carried out process and parse security code by the SMS platform of the Antiforge inquiry terminal server of the present invention, inquiry system is by obtaining security code, data are entered data base querying and obtains Antiforge inquiry, obtain Query Result, return to client；In like manner processing for needing the product unblanked also to take same method to split code-locked, coded lock opened by the password returned by system.After some product is inquired about by this inquiring technology, same phone number (smart mobile phone) or uniform machinery visual apparatus number cannot be carried out again inquiry next time, code of unblanking is inquired about once only, prevent packing box from reusing the phenomenon such as fraud and malice inquiry, contrast compared with technology, the suitability of the present invention is high, efficiency is high, accuracy rate is high, and false proof is effective, can replace traditional artificial Antiforge inquiry.
Finally should be noted that; above example is merely to illustrate technical scheme but not limiting the scope of the invention; although the present invention being explained in detail with reference to preferred embodiment; it will be understood by those within the art that; technical scheme can be modified or equivalent replacement, without deviating from the spirit and scope of technical solution of the present invention.
