Description
[technical field]
The present invention relates to financial payment field, particularly relate to a kind of adopt vocal print to discriminate one's identification safe payment method and corresponding system.
[background technology]
Because bank card is easy to carry, and easily use, carry out method of payment fast and easily to card master tape, so the use of bank card is more and more general, a lot of people has more than a bank card.Although bank card gives card main method of payment fast and easily, but also security personnel's problem served by band, some offenders steal other people bank card data by all means, then copy false card and carry out consumption payment, or usurp the main bank card data of card in consumption online, card is main generally to receive monthly statement after just can realize that the bank card account of oneself is usurped by people, order card is main to sustain a loss, and is a problem extremely to be solved.For protection bank card account safety, the bank card account preventing card from leading is stolen, and proposes safe payment method that employing vocal print of the present invention discriminates one's identification and corresponding system.
[summary of the invention]
Object of the present invention, be to provide a kind of adopt vocal print to discriminate one's identification safe payment method and corresponding system, to realize the multiple application in secure payment.
In general payment process, usually bank card, password etc. is utilized to carry out the identity of authenticated, if but the bank card account data of user or bank card have been stolen by thief together with password, existing payment system generally only relies on bank card, password etc. to differentiate user identity, as long as bank card and password are by checking, even if user non-user, payment system is also difficult to find, this leak makes the user of existing payment system bear very large risk.The present invention by payment process by the biological characteristic " sound " of authenticated as add security means, ensure the bank account safety of user.
The biological characteristic of people comprises appearance, fingerprint, sound etc., and everyone has its " personalization " feature, and the biological characteristic of different people all can have difference, as long as different people just can distinguish by the difference found out wherein.In the biological characteristic of various people, the most easily realize using " sound " of authentication of users as identity documents when paying, just be easy to immediately converse with user by the mobile phone of user, thus " sound " that obtains user carries out identification checking, the present invention utilizes existing vocal print authentication technique exactly, improves the security of payment in time paying as the identity of authentication of users.
The object of the present invention is achieved like this, adopt a kind of like this safe payment method adopting vocal print to discriminate one's identification, it is characterized in that, described method comprises and arranges vocal print authentication server (5), vocal print authentication server (5) is connected with payment network (4) and communication network (6) phase telecommunication respectively, vocal print authentication server (5) records the account data of bank card (1) account of each user, and according to the vocal print Sample Establishing sound-groove model of each user, and bank card (1) account of each user is associated with the mobile phone (2) of this user and sound-groove model, and, when the transaction terminal (3) that payment network (4) receives trade company sends the transaction request of bank card (1) account belonging to user, payment network (4) is except carrying out conventional each transaction step, also carry out communication by vocal print authentication server (5) through communication network (6) and the mobile phone (2) of this user, vocal print authentication server (5) carries out voice print verification according to the sound-groove model of this user to this user, after voice print verification success, payment network (4) just proceeds the subsequent step of this transaction, otherwise refuse this transaction.
And, also adopt a kind of like this safety payment system adopting vocal print to discriminate one's identification, it is characterized in that, described system comprises bank card (1) and the mobile phone (2) of user, the transaction terminal (3) of trade company, payment network (4), vocal print authentication server (5), wherein, described vocal print authentication server (5) is connected with payment network (4) and communication network (6) phase telecommunication respectively, vocal print authentication server (5) records the account data of bank card (1) account of each user, and the sound-groove model of each user of vocal print Sample Establishing according to each user, and bank card (1) account of user is associated with the mobile phone (2) of this user and sound-groove model, described transaction terminal (3) is by wire/radio network such as mobile telephone network, WIFI network, Local Area Network, internet etc. disparate networks access payment network (4), and, when the transaction terminal (3) that payment network (4) receives trade company sends the transaction request of bank card (1) account belonging to user, payment network (4) is except carrying out conventional transaction step, also carry out communication by vocal print authentication server (5) through communication network (6) and the mobile phone (2) of this user, vocal print authentication server (5) carries out voice print verification according to the sound-groove model of this user to this user, after voice print verification success, payment network (4) just proceeds the subsequent step of this transaction, otherwise refuse this transaction.
So just achieve object of the present invention well.
Method of payment of the present invention and system, when user pays, confirm the validity of identity by the biological characteristic " sound " of authentication of users, to ensure bank card (1) account safety of user.Even if the bank card account of user is usurped by thief, as long as user does not lose mobile phone (2), add that thief is difficult to " sound " that puppet emits user, make the money that thief is difficult to successfully in hijacking accounts, ensured the bank card account safety of user.In addition, in the present invention, voice print verification is not the step and method for replacing regular trading wherein identity verification, and voice print verification just as the additional means of identifying user identity, makes payment system safety and reliability.
