Description
Technical field
The present invention relates to wireless short-distance transmission technique field and technical field of network security, be specifically related to a kind of wireless Key payment system based on visible light communication and method of payment.
Background technology
Visible light communication (VisibleLightCommunications, VLC) technology is using white light LEDs as light source, using photoactor or optical imaging device as photodetector, take air as channel, will the wireless light communication technology of the enterprising Serial Communication of visible ray that signal madulation sends at LED be sent.This technology is arisen at the historic moment along with the fast development of LED illumination (i.e. solid state lighting) technology.
Because compare with the conventional light source such as incandescent lamp and daylight lamp, LED has much wide modulation band-width, and can carry out switching over higher frequency, this makes to carry out high-speed communication using LED as light source becomes possibility.Because modulating frequency is very high, human eye is not aware of the flicker of light.Usually, visible light communication as second function of LED, can complete communication while illumination.
Along with the development of ecommerce, ebanking services is more and more universal.In order to ensure the security of online financial transaction, simultaneously also in order to improve the convenience of use, various payment safeguards technique arises at the historic moment.Current technology has bluetooth, NFC, E-token dynamic password card, USBKey etc.Various technology respectively has relative merits, wherein comparatively conventional with USBKey.
Bluetooth poor anti jamming capability, network performance is subject to the interference of other short distance wireless technicals, and equipment cost is high.
NFC is by NFC radio-frequency (RF) receiving/transmission device and mobile communication, but NFC popularization degree on mobile phone is low, and NFC chip cost is high.
E-token dynamic password card adopts symmetric encipherment algorithm, and dynamic code is generated according to particular encryption algorithm by chip, and according to time and number of times generation password at that time, server is also according to same cryptographic algorithm generating cipher, and user inputs rear server check unanimously.The method cost is low, simple to operate, but based on the system reliance server Verification System of this technology and network manager, and this just has very high requirement to the consciousness of the security of Verification System, stability and network manager itself.
USBKey adopts rivest, shamir, adelman, and the digital signature of user and private key can only be generated by USBKey itself and can not derive.USBKey sets physical button, manually presses in limiting time and confirm that button could be signed and is successfully completed transaction, can prevent hacker from imitating transactional operation; By display on-screen-display message, under can preventing the unwitting situation of user, data are tampered.USBKey is designed with higher security.
The using method of current application USBKey is more widely, when logging in internet banking system, computing machine inserts USBKey, then inputs PIN code, is verified the transaction of laggard line correlation.By asymmetric encryption, private key is safely stored in USBKey, compensate for the defect of E-token dynamic password card list key encryption.But the application scenarios of USBKey is single, use when can only operate transaction on computers.
Summary of the invention
For the defect of each payment safeguards technique existence at present, the present invention adopts visible ray technology as gordian technique, provide a kind of wireless Key payment system based on visible light communication and method of payment, improve existing USBKey equipment and use-pattern, make it to set up to communicate with mobile phone to realize concluding the business, also can set up to communicate with computing machine and realize concluding the business, make the process of payment safer, quick, stable.
Wireless Key payment system based on visible light communication provided by the invention, relates to smart mobile phone, Key and computing machine.
Smart mobile phone comprises flashlamp, camera and client software; Wherein, flashlamp is used for sending signal by high frequency flicker; Camera is for reading the Quick Response Code of Key; Client software is for controlling the payment flow of smart mobile phone.
Key comprises control module, visible ray receiver module, USB interface, display screen and battery.Wherein, control module, for storing private key and the digital certificate of user, utilizes the built-in certification of public key algorithm realization to user identity, utilizes digital certificate to be encrypted generation Quick Response Code to transaction data; Display screen is for showing text message and Quick Response Code; The visible light signal that PD module is sent for receiving mobile phone flashlight.USB interface communicates for accessing computing machine.Battery is built in Key, when mobile phone uses Key to conclude the business for Key powers, when Key charges by during USB interface access computing machine.
Smart mobile phone sets up two-way communication link with Key, utilizes flashlamp to send visible light signal to the PD module of Key, utilizes the Quick Response Code on camera reading Key screen.
Based on above-mentioned wireless Key payment system, the wireless Key method of payment based on visible light communication of the present invention, when being undertaken by smart mobile phone, performing step is:
Step 1, enters mobile phone client software, and Key is opened in prompting;
Step 2, opens Key, and the display screen display of Key comprises the Quick Response Code of device id and account authentication sequence;
Step 3, mobile phone camera reads Quick Response Code, verifies the corresponding relation of account on Key and mobile phone;
Step 4, confirm Key be corresponding with the account on mobile phone after, mobile phone inputs the PIN code of Key;
Step 5, PIN code and transaction data are sent to Key by flashlamp high frequency flicker by mobile phone, and Key receives visible light signal by PD module, and after Key receives signal, receive information in the display screen display of Key complete, mobile phone stops sending visible light signal;
Step 6, Key verifies PIN code, when being verified, demonstrates transaction data on a display screen;
Step 7, after user confirms that the content of display on Key is correct, click acknowledgement key on Key, control module utilizes digital certificate to be encrypted generation Quick Response Code to transaction data, and shows on a display screen;
Step 8, mobile phone receives Quick Response Code by camera;
Step 9, the transaction data of encryption is sent to Accounting system server by mobile phone;
Step 10, Accounting system server completes according to instruction and transfers accounts, the success of SMS notification customer transaction, closing the transaction.
The present invention is based on wireless Key payment system and the method for visible light communication, its advantage and good effect are:
(1) on the basis of existing USBKey, only with the addition of visible ray receiver module (PD module) and battery, circuit does simple transformation and can realize on existing basis, and cost is very low; Compared to bluetooth and NFC technique, the LED flashlamp used in the present invention compares bluetooth and NFC module with driving circuit, PD module, and cost is much lower.
(2) compared to existing USBKey, the present invention not only can access computing machine and operate, and independent can also operate with mobile phone, be convenient for carrying, use-pattern is flexible, can by charging Reusability, and the life-span is long.
(3) compared to Bluetooth technology, visible light signal can not be subject to the interference of other wireless signal easily, and visible ray is applicable to various environment, does not worry electromagnetic interference (EMI), also can not damage health as radiofrequency signal.The present invention, by utilizing the characteristics such as visible ray is directed, point-to-point, human eye is visible, improves the security of payment process; So that the visible ray technology of electromagnetic interference (EMI) can not be subject to as gordian technique, improve the robustness of payment process.
