The application platform provided by the embodiment comprises a streaming media recognition computing server, a user data storing server and an application server; the streaming media recognition computing server is used for recognizing the surface of a credit card and processing the credit card number; the user data storing server is used for storing and managing the user information; the application server is used for transferring relation application to run in the application server according to the user access requirements.
Description
Technical field
The present invention relates to cloud computing, Signal and Information Processing, data encryption, data encoding, data show, data transmission, image recognition, data storage, and mobile phone and payment technical field, the technology that especially belongs to the technology based on image recognition and realize on-line payment based on image recognition.
Background technology
On-line payment refers to based on internet, mobile Internet, completes a kind of payment transaction mode of the serial processes such as online monetary payoff from terminal user to businessman of enterprise, fund clearing, query statistic.Business moves one of maximum obstacle of facing of application order, allows exactly the user be really a commodity payment.Using credit card or bank card to carry out in the process of on-line payment, the first step is exactly that traditional approach is generally manual input card number to the obtaining of card number; Manual input mode, needs to input continuously the numeral of 16～18, and for most users, this process is very unfriendly, and error probability is very high, causes sales payment termination of procedure.And account information is easily intercepted in transmitting procedure, by lawless person is utilized, carry out pseudo-blocking and steal account fund.A kind of cloud service platform based on video flowing recognition technology, realize the method for on-line payment and apply efficient filter characteristic extraction algorithm and rational Classing Method of on-Line, and these complex calculations process migrations have been arrived to high in the clouds completed, and user only need to obtain Media Stream image by normal domestic use computer camera or mobile phone camera, synchronously identification is also encrypted in point-to-point transmission process.Fast, conveniently, non-contacting mode accurately identifies credit card, bank card number, and then completes on-line payment safely, efficiently.Adopt cloud computing service platform can significantly reduce user's input cost, for user provides fast, the service of video flowing identification easily.
Summary of the invention
The object of the invention is to: adopt pure software mode, by family expenses camera, the first-class multimedia equipment of cell-phone camera, credit card card face is scanned, and adopt efficient character recognition technologies, automatic quick obtain under credit card number, credit card the credit card card face essential informations such as bank, and then complete payment.And these complicated mathematical operations are moved to high in the clouds complete, user profile is rationally stored, significantly reduce client's input cost, can provide real-time on-line payment service for user.
The technical scheme that the present invention takes is:
Gordian technique 1: adopt the mathematical algorithm of optimizing to ensure the real-time of software identification
In whole identifying, edge detection process belongs to intensive link; Therefore adopting the mathematical algorithm of optimizing to carry out calculated amount optimization, is the key that guarantees identification real-time; For special substance and the texture situation of credit card, I.D., we have carried out large data sample analysis to different edge detection operators; Comparison for Roberts boundary operator, Sobel boundary operator, Prewitt boundary operator, Laplacian boundary operator, Canny boundary operator scheduling algorithm, Canny operator edge detection algorithm after final selected optimization, its algorithm can elimination noise has the optimal selection method in the single order differential algorithm of rim detection that can keep the edge information characteristic; Optimize the algorithm having and can adaptively to detecting the discrimination threshold of operator, carry out analysis and regulation; Thereby effectively reduce calculated amount, guarantee the real-time detecting.
Gordian technique 2: accurately controlled identification process guarantees the accuracy of software identification
The accuracy rate of identification just depends on design and the management and control of whole identification process; Our system platform has been carried out more meticulous planning and design to identification process; Design cycle comprises intercepting video frames (VideoFrameShot), rim detection (EdgeDetection), image normalization pre-service (Normalization), card surface analysis cutting (Analysis), feature extraction (FeatureExtraction), character recognition (Recognition), aftertreatment (PostProcessing), the links such as semantic comparative analysis; For guaranteeing the accuracy of overall flow, we are optimized processing to each the subring joint in flow process, thereby controlled to whole processing and identification flow process; Large data sample is tested repeatedly, and whole recognition accuracy has reached 95%.And in Continuous optimization.
Gordian technique 3: improved minimum distance classifier recognizer is guaranteed software identification fault-tolerance
Due to the scene environment more complicated of the actual use of software, so the fault-tolerance of software algorithm is a key factor; And the link that affects fault-tolerance maximum is the identification of character; Consider that character recognition is mainly English and digital, minimum distance classifier is the sorting algorithm based on vector space model, in image recognition processing and text classification field, has unique advantage; In order to adapt to actual use scenes, we have taked a kind of new disaggregated model weighted minimum distance classifier (Weighted Minimum Distance Classifier) based on standardization Euclidean distance.
Gordian technique 4: for " cloud computing service platform " architecture design and the exploitation that customizes user
Consideration provides different differentiated services for different user's requests, computer cloud computing technology, our architecture design " video flowing identification cloud computing service platform (VRCSP) "; By using cloud computing service platform, can significantly reduce user's input cost, for user provides fast, the service of video flowing identification easily (as: credit card identification service, recognition of face service, I.D. identification serve etc.).
Embodiment
Based on a video flowing recognition technology cloud computing service platform, adopt credit card, bank card recognition technology, in conjunction with cloud computing platform, complete online transaction and pay; Consumer carries out the scanning of card face by camera (as: embedded in mobile phone camera, computer camera etc.) to credit card, the bank card of needs consumption, video flowing intercepting 3～4 pictures of scanning, software is by the video pictures of intercepting, in conjunction with user basic information packing, by Internet Transmission, arrive cloud computing center; The video pictures that cloud computing center gets performs mathematical calculations, image is processed, image recognition; The credit card number that final extraction consumer will pay, or bank card number; Cloud computing center completes the record of consumer information simultaneously; Credit card, bank card number and substantially block surface information and confirm after, transfer to banking data base; Banking data base verifies consumer's identity, as: short-message verification coding mode etc.; Consumer's identity and Transaction Information complete this transaction after confirming; Cloud computing platform records this consumption information.
