Embodiment
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.
As shown in Figure 1, NFC method for secure transactions proposed by the invention relates to NFC label 1, mobile device 2 and server 3 three aspects.NFC label 1 has unique user identification code, i.e. UID (User Identity) code.Businessman calculates by the unique user identification code of proprietary encryption algorithm to this NFC label 1, to generate a safe identification code after obtaining NFC label 1.NFC label read write line by being provided with this proprietary encryption algorithm is encrypted calculation to NFC label, obtains the safe identification code of this NFC label.After obtaining the safe identification code of NFC label 1, by this NFC label read write line, safe identification code is write NFC label 1 again, as the secure data of this NFC label 1 together with the unique user identification code of NFC label 1, meanwhile, by the unique user identification code of NFC label 1 and safe identification code stored in server 3.Store the secure data of multiple NFC label 1 in server 3, the user identification code identification code safe with it of same NFC label 1 binds together, and has mutual corresponding relation.The corresponding different commodity of different NFC label 1 or service, have different transaction values, therefore, also store the Transaction Information corresponding with each NFC label 1 in server 3, as information such as the title of commodity or service and transaction values.Mobile device 2 need support NFC function, as supported the mobile phone, panel computer etc. of NFC function.NFC method for secure transactions comprises the steps:
Mobile device 2 scan N FC label 1, obtain the secure data of this NFC label 1, then by above-mentioned proprietary encryption algorithm, the unique user identification code in the secure data obtained is calculated, be confirmed whether the safe identification code that can draw in secure data, if can not draw, can judge that this NFC label 1 is as illegal, then to shut the book flow process, if can draw, then tentatively can determine that this NFC label 1 is for legal, can enter next step transaction flow.Mobile device 2 calculates by the unique user identification code of application program to NFC label 1 of its inner prepackage, should comprise above-mentioned proprietary encryption algorithm in this application program.This application program can be developed by the businessman of the commodity or service that provide this NFC label 1 correspondence or authorize exploitation, and mobile device 2 also can be communicated with server 3 by this application program.
After mobile device 2 confirms to be obtained the safe identification code in its secure data obtained by calculation, the secure data of this NFC label 1 obtained is sent to server 3, to carry out further legitimate verification to NFC label 1.As previously mentioned, in server 3, store the secure data of each NFC label 1, therefore, if this NFC label 1 is legal, then ought to inquire the secure data that it has stored this NFC label 1 in server 3.Based on this, server 3 judges the legitimacy of this NFC label 1 further by the secure data (namely identical with the secure data of this NFC label 1 that it receives from mobile device 2 secure data) inquired about it and whether stored this NFC label 1.If server lookup has stored the secure data of this NFC label 1 to it, then judge that this NFC label 1 is as legal, so the Transaction Information corresponding with NFC label 1 prestored is sent to mobile device 2, mobile device 2 can be concluded the business according to this Transaction Information; Otherwise, judge that this NFC label 1 is as illegal, stops transaction flow.
As shown in Figure 2, based on above-mentioned NFC method for secure transactions, present invention also offers a kind of NFC affaris safety trade system, this transaction system comprises mobile device 2 and server 3.
Mobile device 2 scan N FC label 1, to obtain the secure data of this NFC label 1.Secure data comprises unique user identification code and safe identification code, and this safe identification code is drawn for being calculated to this unique user identification code by proprietary encryption algorithm.
After obtaining the secure data of this NFC label 1, mobile device 2 is calculated to the unique user identification code in secure data by above-mentioned proprietary encryption algorithm, is confirmed whether the safe identification code that can draw in secure data.When confirm by above-mentioned proprietary encryption algorithm to the unique user identification code in secure data calculate the safe identification code that can draw in secure data time, the secure data of this NFC label 1 is sent to server 3, to carry out further legitimate verification to NFC label 1.Mobile device 2 inside is preinstalled with application program, and this application program includes above-mentioned proprietary encryption algorithm, and mobile device 2 calculates to unique user identification code by the application program of its inner prepackage.
Server 3 inquires about the secure data whether it has stored this NFC label 1, and when inquiring it and having stored the secure data of this NFC label 1, the Transaction Information of corresponding with this NFC label 1 (as corresponding with the user identification code of this NFC label 1) that prestored is sent to mobile device 2, and mobile device 2 is concluded the business according to Transaction Information again.
The specific works principle of mobile device 2 and server 3 with reference to described in above-mentioned NFC method for secure transactions, can not repeat them here.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
