S101; Judge between the payer distance whether in first distance range and the frequency of sound wave whether in the first frequency scope; If the distance between the payer is in first distance range and the frequency of sound wave is in the first frequency scope, then the mode with sound wave connects;
First distance range described in this step can be 10～15 centimetres; The first frequency scope can be 1～10KHz (intensity of sound is in 0.5～1.0 decibel); Distance between the equipment of payer will remain within 10～15 centimetres the scope so; And the frequency limitation of sound wave guarantees the safety and the coverage transmission of sound wave in 1～10KHz scope, prevents that data from being tackled; The hardware capabilities of suitable device, sonic transmissions scope and battery ability also adapt to the restriction of the distance between the payer;
Said payer comprises the both sides that pay or in many ways, and the loudspeaker through payer are with microphone connects and carry out sonic transmissions, and frequency of sound wave is arranged in the scope of 1～10KHz concluding the business before;
Especially, the first frequency scope is 1～5KHz preferably, is in the loudspeaker and all accessible frequency range of microphone of ordinary terminal equipment, can also provide abundant bandwidth in order to the transmission coded signal, and it is uncomfortable to be unlikely the too high people's of the causing ear of frequency in addition;
When said mode with sound wave connects, identification information of each self-generating of payer, and send to the other side through the mode of sound wave; The other side receives said identification information with the form of sound wave again; That is, when said mode with sound wave connects, pay a side and/or identification information of payment each self-generating of the opposing party, and send to payment the opposing party and/or pay a side through the mode of sound wave; Pay the opposing party and/or pay a side and receive said identification information with the form of sound wave again;
Said identification information is unique numeric string or character string, can only be in once concluding the business effectively, and transaction need regenerate once more;
Said identification information only kept 5 minutes; Surpass 5 minutes, said identification information will cease to be in force automatically and delete, when needing transaction; Need payer to connect with the mode of sound wave once more and regenerate an identification information separately, and send to the other side through the mode of sound wave;
After payer connects with the mode of sound wave, the payment both sides or the server data that connects with server respectively, and obtain in many ways;
Said server data is the data relevant with payer of server end storage;
Payer can be to be connected through internet or mobile internet with the connected mode of server;
S102 obtains transaction data, and carries out the exchange of said transaction data with the form of sound wave, is specially:
S1021 converts the transaction data of digital signal to the transaction data of simulating signal;
S1022 sends the transaction data of said simulating signal with the form of sound wave;
S1023 receives the transaction data of said simulating signal with the form of sound wave;
S1024 converts the transaction data of said simulating signal to the transaction data of digital signal;
The said transaction data that obtains comprises that the data of server data, payment one side generation of obtaining payment one side through internet or mobile internet are or/and payment the opposing party's that the form through sound wave gets access to data;
S103 resolves said transaction data, and carries out the exchange of server data;
The exchange of said server data is meant through internet or mobile internet and obtains payment one side's server data and send to the server of paying the opposing party.
The further optimization of such scheme is that said step " converts the transaction data of digital signal to the transaction data of simulating signal " and also comprises before: the transaction data of encrypting said digital signal;
Said encryption can adopt MD5 (Message Digest Algorithm 5, Message Digest Algorithm 5) to encrypt, and security is higher;
Said encryption comprises that said the other side who gets access to is this time set up the identification information that generates when sound wave connects to encrypt;
Said step " converts the transaction data of said simulating signal to the transaction data of digital signal " and also comprises step afterwards:
Decipher the transaction data of said digital signal;
Said deciphering comprises and decrypts the identification information of having encrypted; And judge whether the identification information after the said deciphering is consistent with the identification information of when the mode with sound wave connects, creating certainly; If then resolve the transaction data of said digital signal, and carry out the exchange of server data.
The further optimization of such scheme is that said step " is encrypted the transaction data of said digital signal " and also comprised step afterwards:
Compress the transaction data of said digital signal;
Said step " is deciphered the transaction data of said digital signal " and is also comprised step before:
The transaction data of the said digital signal that decompresses.
Through payer distance and frequency of sound wave are controlled, transaction security reduces the possibility that transaction data is tackled, steals, distorted in the embodiment of the invention, and trading efficiency is high; Convert the transaction data of simulating signal to through transaction data, being suitable for the data-signal of sonic transmissions, convert the transaction data of said simulating signal the transaction data of digital signal to, to be suitable for the exchange of transaction data in server with digital signal; Form transmission transaction data through sound wave especially, carries out sonic transmissions through loudspeaker on the mobile phone and microphone, need not improve or increase hardware device; Extendability is strong, is prone to transplant, and compatible low-end mobile phone; Cost is low, through the control of distance and frequency, transaction security; Reduce the possibility that transaction data is tackled, steals, distorted, trading efficiency is high, through the encryption and decryption to transaction data; Further improve the security of data exchange process, further reduce the possibility that transaction data is tackled, steals, distorted, through with identification information encryption and decryption together; Further improve the security of data exchange process,, improve the efficient and the trading efficiency of data transmission through the process of compression and decompression.
