A transaction information processing method, comprising:
the method comprises the steps of collecting an image of transaction information displayed by a first transaction terminal, identifying the collected transaction image to obtain a transaction amount of a current transaction, displaying a transaction page of the current transaction, wherein the transaction page comprises the transaction amount and a transaction control, collecting a face image of a user in response to transaction operation of the transaction control, sending the face image and the transaction amount to a transaction server, receiving transaction identification information of the current transaction returned by the transaction server according to the face image and the transaction amount, and sending the transaction identification information to the first transaction terminal so as to process the current transaction information.
As shown in fig. 3, the specific flow of the transaction information processing method is as follows:
101. and acquiring an image of the transaction information displayed by the first transaction terminal, and identifying the acquired transaction image to obtain the transaction amount of the current transaction.
The transaction image may be an image displaying transaction information. The transaction image may be an image containing only RGB (one color standard, R is red, G is green, and B is blue) image data streams, and may also be a three-dimensional image containing an RGB image data stream, a depth image stream, and an infrared image stream.
The transaction amount may be an amount of the current transaction, for example, when the current transaction is payment, the transaction amount may be a payment amount, and when the current transaction is transfer, the transaction amount may be a transfer amount.
For example, an image of transaction information displayed by the first transaction terminal may be collected to obtain a transaction image, and text recognition may be performed on the transaction image to obtain a transaction amount of the current transaction, which may specifically be as follows:
and S1, acquiring the image of the transaction information displayed by the first transaction terminal to obtain a transaction image.
For example, a display position of a display area of the first transaction terminal may be obtained, where the display area is used to display transaction information, the display area is monitored according to the display position, and when the transaction information exists in the display area, an image of the transaction information is collected to obtain a transaction image, which may specifically be as follows:
(1) and acquiring the display position of the display area of the first transaction terminal.
The display area is used for displaying transaction information, and is generally an area of a Light Emitting Diode (LED) screen of the first transaction terminal.
For example, the position of the display area of the first transaction terminal may be recognized by an image capturing module in the first transaction information processing apparatus, and the position is used as the display position, for example, an LED display screen of the first transaction terminal is recognized in space by a self-contained 2D camera or 3D camera, and the position of the LED display screen is acquired, so as to obtain the display position of the display area.
The 2D camera is used for collecting RGB image data streams, the 3D camera can collect the RGB image data streams and also support collection of related data such as infrared image data streams and depth image data streams, and the cost of the 3D camera is higher than that of the 2D camera, so that the 2D camera can be used for collecting images of transaction information in the aspect of saving cost.
After acquiring the display position of the display area of the first transaction terminal, the method may further calibrate the acquisition position of the image acquisition module of the first transaction processing apparatus, for example, calibrate the acquisition position of the 2D camera and/or the acquisition position of the 3D camera, and therefore, after acquiring the display position of the display area of the first transaction terminal, the method for processing the transaction information may further include:
acquiring an image of a display area according to the display position to obtain a transaction image sample set, identifying transaction image samples in the transaction image sample set to obtain a text content sample set, and calibrating the acquisition position of the image of the acquisition display area according to the text content sample set.
For example, a 2D or 3D camera may be used to continue images of the display area of the first transaction terminal according to the display position, so as to obtain a transaction image sample set. Performing text Recognition on the transaction sample images in the transaction image sample set to obtain a text content sample set, for example, performing text Recognition on the transaction sample images in the transaction image sample set by using an Optical Character Recognition (OCR) Recognition component to obtain text contents of the transaction sample images, thereby obtaining the text content sample set.
The method includes the steps of calibrating the acquisition position of an image of an acquisition display area according to a text content sample set, for example, sequencing text content samples in the text content sample set according to the acquisition time of transaction image samples, screening out a preset number of text content samples in the sequenced text content sample set, and comparing the text content samples, for example, screening out text content samples corresponding to two continuous transaction image samples in the sequenced text content sample set, and comparing the contents of the two text content samples.
Calibrating the acquisition position of the image of the acquisition display area according to the comparison result of the text content samples, for example, when the text content samples are the same, determining that the acquisition position is calibrated, wherein the acquisition position can be position information such as an angle, a distance and the like between a camera and an LED display screen of the first transaction terminal, and the acquisition position is used as the calibrated acquisition position; when the text content samples are different, it is indicated that the acquisition position still needs to be calibrated at the moment, an administrator or a transaction facilitator adjusts position information such as an angle, a distance and the like between a camera and an LED display screen of the first transaction terminal, then, the step of acquiring images of a display area according to the display position is returned to be executed, and a transaction image sample set is obtained until the text contents of the transaction image samples of a preset number in the transaction image sample set are the same, for example, the images of the display area are continuously acquired to obtain the transaction image sample set, then, text recognition is carried out on the transaction image samples in the transaction image sample set, text content samples corresponding to two or other transaction image samples of the preset number which are continuously acquired are screened out in the recognized text content sample set for comparison, when the contents of the text content samples are the same, the current acquisition position is taken as the post-calibration acquisition position, and when the contents of the text content samples are different, continuously adjusting the acquisition position of the camera until the text contents of the transaction image samples of continuous quantity are the same, and taking the acquisition position at the moment as the post-calibration acquisition position.
(2) And monitoring the display area according to the display position.
For example, the display area is monitored according to the display position and the post-calibration acquisition position, for example, a camera at the post-calibration acquisition position is used to monitor the display area corresponding to the display position, and whether display content exists in the display area is mainly monitored. When the display area has the display content, the camera can be triggered to acquire the content displayed in the display area, so that a transaction image is obtained.
(3) And when the transaction information exists in the display area, acquiring an image of the transaction information to obtain a transaction image.
For example, when the display area displays content, it may be determined that transaction information exists in the display area, and at this time, the camera may be triggered to acquire an image of the transaction information to obtain a transaction image, and the acquisition process may be performed continuously, for example, directly in a form of a video data stream, or may be performed continuously at a preset acquisition speed to acquire the transaction information in the display area. The acquisition may be performed periodically or periodically, for example, when there is transaction information in the display area, the acquisition is performed for the first time, and then the acquisition is continued at an interval of one period, or after the acquisition for the first time, a time is set to perform the acquisition periodically, so as to obtain a transaction image. When the transaction images are collected, the transaction images can be sent to the OCR recognition component for recognition in real time, the transaction images can be sent to the OCR recognition component for recognition regularly, and when the quantity of the collected transaction images reaches a preset quantity, the transaction images can be sent to the OCR recognition component for recognition.
Optionally, when acquiring a transaction image, it is further necessary to determine whether the first transaction information processing device is in an idle state, when the first transaction information processing device processes the idle state, the transaction image may be acquired, when the first transaction information processing device is not in the idle state, the transaction image may not be acquired, the non-idle state is that the first transaction information processing device is acquiring a facial image of a user, and for more accurately identifying the user, a three-dimensional image of the face of the user may be acquired in an embodiment of the present application, so the transaction information processing method further includes:
acquiring process information of the current transaction service, inquiring a three-dimensional image acquisition process in the process information, determining that the current transaction service is in an idle state when the three-dimensional image acquisition process does not exist in the process information, and acquiring an image of the transaction information to obtain a transaction image when the transaction information exists in a display area and the current transaction service is in the idle state.
For example, process information of the current transaction service is screened from the process information set, a three-dimensional image acquisition process is inquired in the process information, when the three-dimensional image acquisition process does not exist in the process information, it is indicated that the first transaction information processing device is not acquiring a three-dimensional image of a user face at the moment, the transaction service of the first transaction processing device can be determined to be in an idle state, and when the transaction service is in the idle state and transaction information exists in a display area, the image of the transaction information can be acquired to obtain a transaction image. When the process information includes a three-dimensional image acquisition process, it indicates that the first transaction information processing device is acquiring a three-dimensional image of the face of the user, and therefore, the transaction service of the first transaction information processing device is in a non-idle state. When the transaction service is in a non-idle state, the steps of collecting transaction images and performing text recognition on the transaction images are not executed.
And S2, identifying the collected transaction image to obtain the transaction amount of the current transaction.
For example, text recognition may be performed on the transaction image to obtain text content corresponding to the transaction image, for example, text recognition may be performed on the transaction image by using an OCR component to obtain text content corresponding to the transaction image. The text content corresponding to the preset number of the continuously acquired transaction images is screened out from the text content to obtain the target text content, for example, taking the preset number of 2 as an example, the text content corresponding to the continuously acquired 2 transaction images is screened out from the text built-in, and can also be understood as the text content corresponding to two continuous frame frames, so as to obtain the target text content, which can be a text content pair. Comparing the text contents in the target text content pair, and when the target text contents in the target text content pair are the same, identifying the transaction content of the current transaction in the target text content, for example, identifying the transaction contents such as the transaction amount, the transaction object and the transaction time of the current transaction in the text content. The method includes extracting amount information of a current transaction from transaction content, obtaining a transaction amount of the current transaction, for example, extracting information related to the amount of the current transaction from the transaction content, obtaining the amount information, and when the amount information is 10 yuan or any other amount or more, taking the amount or more as the transaction amount of the current transaction, where the transaction amount may include a plurality of amounts, for example, amounts such as a price of each transaction item in the transaction and a total price of the transaction items.
102. And displaying a transaction page of the current transaction.
Wherein the transaction page includes a transaction amount and a transaction control.
For example, when the transaction amount of the current transaction is identified, the transaction page of the current transaction may be triggered to be displayed, and the transaction amount may be displayed on the transaction page, which may be as shown in fig. 4. Other text contents and transaction amount in the transaction image can be displayed in the transaction page, and the other text contents can include transaction details, transaction time, payee information and the like. The transaction page can also comprise a transaction control, and when the user confirms that the information such as the transaction amount and the like on the transaction page is correct, the transaction control can be triggered by the user or a transaction service provider, so that a three-dimensional image of the face of the user is acquired.
103. And in response to the transaction operation of the transaction control, acquiring a facial image of the user.
The face image can be a two-dimensional image containing an RGB image data stream, or a three-dimensional image of a user's face containing an RGB image data stream, a depth image data stream, and an infrared image data stream.
For example, in response to a transaction operation of the transaction control, at least one face image of a user's face is collected to obtain a candidate face image set, image attribute information of each candidate face image in the candidate face image set is obtained, and at least one face image is screened out from the candidate face image set according to the image attribute information, which may specifically be as follows:
(1) and responding to the transaction operation of the transaction control, and acquiring at least one face image of the face of the user to obtain a candidate face image set.
For example, in response to a transaction operation of the transaction control, a 3D camera of the first transaction information processing device is triggered to be turned on, at least one three-dimensional image of the face of the user is acquired, and when the three-dimensional image of the face of the user is acquired, the acquisition process and the acquired three-dimensional image can be displayed on a transaction page to obtain a candidate face image set. In the acquisition process, prompt information can be generated according to the acquired candidate facial images and displayed on a transaction page, the prompt information is used for prompting the position and the state of the user during acquisition, for example, when the eyes of the user are detected to be closed in the acquisition process, prompt information for prompting the user to open the eyes can be generated, and when the acquisition process detects that the face of the user is not completely acquired, position prompt information for prompting the user to be close to the 3D camera can be generated.
(2) Image attribute information of each candidate face image in the candidate face image set is acquired.
For example, information such as the face size, face angle, image contrast, image size, image capturing time, image capturing position, image brightness, and sharpness of each candidate face image is identified in the candidate face image set as image attribute information of each candidate face image in the candidate face image set.
(3) And screening at least one face image in the candidate face image set according to the image attribute information.
For example, at least one image parameter value for evaluating the candidate face image is screened out from the image attribute information, and for example, coefficients such as face size, face angle, image contrast, image brightness, and sharpness may be screened out as the image parameter value of the candidate face image. Weighting the image parameter values, for example, obtaining a preset weight corresponding to each type of image parameter value, weighting the image parameter values according to the preset weight, and fusing the weighted image parameter values to obtain a parameter evaluation value of each candidate face image in the candidate face image set. And screening candidate face images with parameter evaluation values exceeding a preset evaluation threshold value from the candidate face image set to obtain the face images. When the number of candidate face images exceeding the preset evaluation threshold is large, the parameter evaluation values may be ranked, and candidate face images with the largest parameter evaluation value or a preset ranking may be screened out as the face images of the user from among these candidate face images.
104. And sending the facial image and the transaction amount to a transaction server, and receiving transaction identification information of the current transaction returned by the transaction server according to the facial image and the transaction amount.
The transaction identification information may be identification information of a user performing a transaction, for example, a payment code, a payment receipt code, or other transaction identification information.
For example, a face image and a transaction amount are sent to a transaction server, so that the transaction server performs living body detection on the face image and adjusts the transaction amount according to a preset adjustment strategy, the transaction server identifies the face image of the user passing the living body detection to obtain an identity of the user, initial transaction identification information of the user is obtained, then the initial transaction identification information is updated according to the adjusted transaction amount to obtain transaction identification information, and the transaction identification information is returned to a first transaction information processing device, so that the first transaction information processing device receives the transaction identification information of the current transaction.
The adjustment of the transaction amount by the transaction server can be understood as the adjustment modes of increasing marketing activities during payment, reducing the transaction amount actually paid, increasing transfer handling fees and the like on the basis of the transaction amount during transfer.
105. And sending the transaction identification information to the first transaction terminal so as to process the current transaction information.
For example, the transaction identification information is sent to the first transaction terminal, for example, taking the transaction identification information as a character string of the payment code as an example, the character string of the payment code is encrypted in the form of HID to the payment code, and the encrypted payment code is sent to the first transaction terminal according to the HID protocol. The first transaction terminal processes the transaction information of the current transaction according to the transaction identification information, for example, taking the current transaction as payment, and processes the payment of the transaction information of the current transaction according to the received payment code, for example, paying the corresponding transaction amount in the payment code to a receiving account in the transaction information according to the payment code, when the transaction server adjusts the transaction amount, if the adjusted transaction amount is less than the original transaction amount, paying the adjusted amount in the payment code of the user to the receiving account, and paying the amount difference value between the adjusted transaction amount and the original transaction amount by the payment account corresponding to the transaction server. If the adjusted transaction amount exceeds the original transaction amount, the transaction scene at the moment can be determined to be a transfer scene, the increased transaction amount is the transaction commission of the original transaction amount, at the moment, the adjusted transaction amount is directly transferred to a collection account according to the payment code of the user, and the first transaction terminal can also send the transaction state corresponding to the transaction identification information to the transaction server.
Optionally, after sending the transaction identification information to the first transaction terminal, the first transaction information processing device may further query the transaction state of the current transaction, for example, send a transaction query request of the current transaction to the transaction server, receive transaction result information returned by the transaction server according to the transaction query request, where the transaction result information includes the transaction state corresponding to the transaction identification information and adjustment information of the transaction amount, and the transaction state may include success, failure, and timeout, where success may be understood as success of the transaction, failure may be understood as failure of the transaction, and timeout may be understood as exceeding the longest transaction time, and the transaction is still unsuccessful. The adjustment information of the transaction amount may be information of increase or decrease of the transaction amount. The adjustment information of the transaction state and the transaction amount corresponding to the transaction identification information is displayed, for example, the adjustment information of the transaction state and the transaction amount corresponding to the transaction identification information is displayed on a transaction page, which may be specifically shown in fig. 5.
As can be seen from the above, in the embodiment of the present invention, after the image of the transaction information displayed by the first transaction terminal is collected, the collected transaction image is identified to obtain the transaction amount of the current transaction, then, the transaction page of the current transaction is displayed, the transaction page includes the transaction amount and the transaction control, the facial image of the user is collected in response to the transaction operation of the transaction control, the facial image and the transaction amount are sent to the transaction server, the transaction identification information of the current transaction returned by the transaction server according to the facial image and the transaction amount is received, and the transaction identification information is sent to the first transaction terminal so as to process the transaction information; according to the scheme, the image of the transaction information is collected, the transaction amount of the current transaction is identified in the transaction image and is displayed in the transaction page, the facial image of the user is collected under the condition that the user determines that the transaction amount is accurate, the transaction identification information is obtained according to the image and the transaction amount, and the transaction information is processed, so that the transaction risk is reduced, and therefore the safety of transaction information processing can be improved.
The embodiment will be described from the perspective of a second transaction information processing apparatus, which may be specifically integrated in an electronic device, which may be a server or the like; the server may be an independent physical server, a server cluster or a distributed system formed by a plurality of physical servers, or a cloud server providing basic cloud computing services such as cloud service, a cloud database, cloud computing, a cloud function, cloud storage, Network service, cloud communication, middleware service, domain name service, security service, Network acceleration service (CDN), big data and an artificial intelligence platform.
A transaction information processing method, comprising:
the method comprises the steps of receiving a face image of a user and a transaction amount of a current transaction, which are sent by a second transaction terminal, carrying out living body detection on the face image, identifying the face image which passes the living body detection to obtain an identity of the user, screening out initial transaction identification information corresponding to the identity from a preset transaction identification information set, adjusting the transaction amount by adopting a preset adjustment strategy, updating the initial transaction identification information according to the adjusted transaction amount to obtain transaction identification information of the current transaction, and sending the transaction identification information to the second transaction terminal so that the second transaction terminal can process the transaction information of the current transaction.
As shown in fig. 6, the transaction information processing method includes the following specific processes:
201. and receiving the face image of the user and the transaction amount of the current transaction, which are sent by the second transaction terminal.
For example, the facial image of the user and the transaction amount of the current transaction sent by the second transaction terminal may be directly received, and when the internal memory of the facial image of the user and the transaction amount of the current transaction is large, the facial image of the user and the transaction amount of the current transaction may also be indirectly received, for example, the second transaction terminal sends the storage address of the facial image of the user and the transaction amount to the second transaction information processing device, and the second transaction information processing device downloads information such as the facial image of the user and the transaction amount of the current transaction in the internal memory or the cache of the second transaction terminal according to the storage address.
202. And performing living body detection on the face image, and identifying the face image passing the living body detection to obtain the identity of the user.
For example, a face image of a user is subjected to living body detection to obtain a living body detection result of the user, when the living body detection of the user is passing, the face image through which the living body detection passes is identified, and identity information of the user in the face image is identified, so that an identity of the user is obtained, for example, the identity of the user in the face image is identified, the identity information is identified, and an identity corresponding to the identity information is obtained, for example, the identity may be a micro signal or other identities of the user.
203. And screening out initial transaction identification information corresponding to the identity in a preset transaction identification information set.
For example, a preset transaction identification information set is obtained, the transaction identification information in the preset transaction identification information set is associated with an identity, and initial transaction identification information corresponding to the identity of the user is screened out from the preset transaction identification information set, for example, by taking the identity of the user as a micro signal, an initial payment code corresponding to the micro signal can be obtained.
204. And adjusting the transaction amount by adopting a preset adjustment strategy, and updating the initial transaction identification information according to the adjusted transaction amount to obtain the transaction identification information of the current transaction.
For example, according to the scene type of the current transaction, a preset adjustment policy corresponding to the scene type is adopted to adjust the transaction amount, for example, when the scene of the current transaction is a payment scene, a preset payment adjustment policy, such as a random decreasing policy, is adopted to randomly decrease the transaction amount to obtain an adjusted transaction amount, when the scene of the current transaction is a transfer scene, a preset transfer adjustment policy, such as a policy of obtaining transfer commission is adopted to determine a commission charge corresponding to the current transaction amount according to the transfer commission charge policy, and the transaction amount is adjusted according to the commission charge, such as adding the commission charge to the transaction amount to obtain the adjusted transaction amount.
Updating the initial transaction identification information according to the adjusted transaction amount to obtain the transaction identification information of the current transaction, for example, modifying the transaction amount corresponding to the payment code into the adjusted transaction amount by taking the transaction identification as the payment code, so as to update the initial transaction identification information to obtain the transaction identification information of the current transaction.
205. And sending the transaction identification information to a second transaction terminal so that the second transaction terminal can process the current transaction information.
For example, the transaction identification information is directly sent to the second transaction terminal, and when the memory of the transaction identification information is large or the number of the transaction identification information is large, the storage address of the transaction identification information can also be sent to the second transaction terminal, so that the second transaction terminal obtains the transaction identification information of the current transaction in the memory or the cache of the second transaction information processing device according to the storage address. And the second transaction terminal sends the transaction identification information to the first transaction terminal, and the transaction information is processed by the first transaction terminal.
Optionally, after the second transaction information processing device sends the transaction identification information to the second transaction terminal, the second transaction information processing device may further receive a transaction query request sent by the second transaction terminal, and return transaction result information to the second transaction terminal according to the transaction query request, for example, obtain a transaction state corresponding to the transaction identification information according to the transaction query request, for example, receive a transaction state corresponding to the transaction identification information of the current transaction fed back by the bank server, where the transaction state may include success, failure, and timeout. Taking the preset adjustment policy and the adjusted transaction amount as adjustment information of the current transaction, for example, taking the preset adjustment policy as random vertical subtraction, the original transaction amount as 10 yuan, the adjusted amount as 0.5 yuan, and the adjusted amount as 9.5 yuan, the adjustment information may be information such as random vertical subtraction of 0.5 yuan, and the adjusted transaction amount as 9.5 yuan. And taking the adjustment information and the transaction state as transaction result information of the current transaction, and returning the transaction result information to the second transaction terminal.
As can be seen from the above, in the embodiment of the present invention, after receiving the face image of the user and the transaction amount of the current transaction sent by the second transaction terminal, the face image is subjected to living body detection, the face image passed by the living body detection is identified to obtain the identity of the user, the initial transaction identification information corresponding to the identity is screened out from the preset transaction identification information set, the transaction amount is adjusted by using the preset adjustment strategy, the initial transaction identification information is updated according to the adjusted transaction amount to obtain the transaction identification information of the current transaction, the transaction identification information is sent to the second transaction terminal, so that the second transaction terminal processes the transaction information of the current transaction, and since the living body detection is performed on the face image of the user, the identity of the user can be identified only when the living body detection passes, and the security of transaction information processing is increased to a certain extent, and the transaction amount of the current transaction sent by the second transaction terminal can be received, so that the transaction amount of the current transaction can be adjusted according to the actual transaction scene, and the safety of transaction information processing can be greatly improved.
The method described in the above examples is further illustrated in detail below by way of example.
In this embodiment, a transaction scene of a current transaction is taken as a payment scene, a first transaction terminal is a cash register terminal, a first transaction information processing device is integrated in a second transaction terminal, the second transaction terminal can be a payment terminal, a second transaction information processing device is integrated in a transaction server, transaction information is payment information, a transaction image is a payment image, a transaction amount is a payment amount, transaction identification information is payment code information, and a face image is a three-dimensional face image.
And (I) calibrating the acquisition position of the image of the acquisition display area by the payment terminal.
For example, the payment terminal recognizes an LED display screen of the first transaction terminal in space through a self-contained 2D camera, and obtains the position of the LED display screen, thereby obtaining the display position of the display area. And according to the display position, a 2D camera is adopted to continuously display the images of the display area of the first transaction terminal, so that a transaction image sample set is obtained. And performing text recognition on the transaction sample images in the transaction sample image set by adopting an OCR component to obtain the text content of the transaction sample images, so as to obtain a text content sample set. And sequencing the text content samples in the text content sample set according to the acquisition time of the transaction image samples, and screening out the text content samples corresponding to two continuous transaction image samples in the sequenced text content sample set.
The contents of the two text content samples are compared. When the text content samples are the same, the collection position calibration can be determined to pass, the collection position can be position information such as an angle and a distance between the camera and the LED display screen of the first transaction terminal, and the collection position is used as the collection position after calibration. When the text content samples are different, the administrator or the transaction facilitator adjusts the angle, the distance and other position information between the camera and the LED display screen of the first transaction terminal, continues to collect the images of the display area to obtain a transaction image sample set, then performs text recognition on the transaction image samples in the transaction image sample set, screening out text content samples corresponding to two or other transaction image samples of preset quantity continuously collected in the identified text content sample set for comparison, when the content of the text content sample is the same, the current acquisition position is taken as the post-calibration acquisition position, and when the contents of the text content samples are different, continuously adjusting the acquisition position of the camera until the text contents of the transaction image samples of continuous quantity are the same, and taking the acquisition position at the moment as the post-calibration acquisition position.
And (II) acquiring a corresponding 2D camera after calibration, and processing the transaction information displayed by the cash register terminal.
As shown in fig. 7, a transaction information processing method may specifically include the following processes:
301. the payment terminal acquires the image of the payment information displayed by the cash register terminal to obtain the payment image.
For example, the payment terminal monitors a display area corresponding to the display position by using a camera for acquiring the position after calibration, and mainly monitors whether display content exists in the display area. When the display area displays content, it can be determined that payment information exists in the display area, at this time, the camera can be triggered to acquire an image of the payment information to obtain a payment image, and the acquisition process can be continuously acquired, for example, the acquisition is directly performed in a video data stream mode, or the acquisition is performed continuously on the payment information in the display area at a preset acquisition speed. The collection may be performed periodically or periodically, for example, when the payment information exists in the display area, the first collection is performed, and then the collection is continued at an interval of one period, or after the first collection, a time is set to perform the collection periodically, so as to obtain the payment image. When gathering the payment image, can send in real time for OCR recognition component discerns, can also regularly send the payment image to OCR recognition component and discern, can also wait to gather when the quantity of payment image reaches preset quantity, send the payment image to OCR recognition component again and discern.
Optionally, when the payment image is collected, it is further required to determine whether the payment service of the payment terminal is in an idle state, for example, the payment terminal screens out process information of the current transaction service from the process information set, and queries a three-dimensional image collection process in the process information, when the three-dimensional image collection process does not exist in the process information, it is indicated that the payment terminal does not collect a three-dimensional image of a user face at this time, and it can be determined that the payment service of the payment terminal is in the idle state, and when the payment information exists in a display area, the image of the payment information can be collected to obtain the payment image. When the process information contains a three-dimensional image acquisition process, the three-dimensional image of the face of the user is acquired by the payment terminal at the moment, so that the payment service of the payment terminal is in a non-idle state. And when the payment service is in a non-idle state, the steps of collecting the payment image and performing text recognition on the payment image are not executed.
302. And the payment terminal identifies the collected payment image to obtain the payment amount of the current transaction.
For example, the payment terminal performs text recognition on the payment image by using the OCR component, so as to obtain text content corresponding to the payment image. Taking the preset number of 2 as an example, the text content corresponding to 2 continuously collected payment images is screened out from the text built-in, and can also be understood as the text content corresponding to two continuous picture frames, so as to obtain the target text content, and the target text content can be a text content pair. And comparing the text contents in the target text content pair, and identifying the transaction contents such as the payment amount, the transaction object, the transaction time and the like of the current transaction in the text contents when the target text contents in the target text content pair are the same. The information related to the amount of the current transaction is extracted from the transaction content, and the amount information is obtained, when the amount information is 10 yuan or any other one or more amounts, the one or more amounts can be used as the payment amount of the current transaction, and the payment amount can include a plurality of amounts, for example, the amount can be the price of each transaction item in the transaction and the total price of the transaction items.
303. And the payment terminal displays a payment page of the current transaction.
For example, when the payment amount of the current transaction is identified, the payment terminal may be triggered to display a payment page of the current transaction, the payment amount is displayed on the payment page, and other text contents and payment amount in the payment image may be displayed on the payment page, where the other text contents may include transaction details, transaction time, and payee information. The payment page can also comprise a transaction control, when the user confirms that the information such as payment amount and the like on the payment page is correct, the transaction control can be triggered by the user or a transaction service provider, and the triggering mode can comprise a click triggering mode, a sound triggering mode or a sliding triggering mode and the like, so that the three-dimensional image of the face of the user is collected.
304. And responding to the transaction operation of the transaction control, and acquiring at least one three-dimensional image of the face of the user by the payment terminal to obtain a candidate three-dimensional face image set.
For example, in response to a transaction operation of a transaction control, a 3D camera of the payment terminal is triggered to be turned on, at least one three-dimensional image of the face of the user is acquired, and when the three-dimensional image of the face of the user is acquired, the acquisition process and the acquired three-dimensional image can be displayed on a payment page to obtain a candidate three-dimensional face image set. In the acquisition process, prompt information can be generated according to the acquired candidate three-dimensional face images and displayed on a payment page, and the prompt information is used for prompting the position and the state of a user during acquisition.
305. The payment terminal acquires image attribute information of each candidate face three-dimensional image in the candidate three-dimensional face image set.
For example, the payment terminal recognizes information such as a face size, a face angle, an image contrast, an image size, an image capturing time, an image capturing position, an image brightness, and a sharpness of each candidate face three-dimensional image in the candidate three-dimensional face image set as image attribute information of each candidate face three-dimensional image in the three-dimensional face image set.
306. And the payment terminal screens out at least one three-dimensional face image in the candidate three-dimensional face image set according to the image attribute information.
For example, the payment terminal may filter out coefficients such as face size, face angle, image contrast, image brightness, and sharpness as image parameter values for the candidate three-dimensional face image. And acquiring a preset weight corresponding to each type of image parameter value, weighting the image parameter values according to the preset weight, and fusing the weighted image parameter values to obtain a parameter evaluation value of each candidate three-dimensional face image in the candidate three-dimensional face image set. And screening candidate three-dimensional face images with parameter evaluation values exceeding a preset evaluation threshold value from the candidate three-dimensional face image set to obtain the three-dimensional face images. When the number of candidate three-dimensional face images exceeding the preset evaluation threshold is large, the parameter evaluation values may be ranked, and a candidate three-dimensional face image with the largest parameter evaluation value or a preset ranking is selected from the candidate three-dimensional face image set as the three-dimensional face image of the user.
307. And the payment terminal sends the three-dimensional face image and the payment amount to the transaction server.
For example, the payment terminal may directly send the three-dimensional facial image and the payment amount to the transaction server, when the memory of the three-dimensional facial image of the user and the payment amount of the current transaction is large, the payment terminal sends the memory address of the three-dimensional facial image of the user and the payment amount to the transaction server, and the transaction server downloads the information such as the three-dimensional facial image of the user and the payment amount of the current transaction in the memory or the cache of the payment terminal according to the memory address.
308. And the transaction server performs living body detection on the three-dimensional face image, and identifies the three-dimensional face image passing the living body detection to obtain the identity of the user.
For example, the transaction server performs live body detection on a three-dimensional face image of the user to obtain a live body detection result of the user, and when the live body detection of the user is passed, the three-dimensional face image passed by the live body detection is identified, identity information of the user in the three-dimensional face image is identified, and a micro signal corresponding to the identity information of the user can be used as an identity of the user according to the identity information of the user by taking a payment platform as an example of micro-letter payment.
309. And the transaction server screens out initial payment code information corresponding to the identity in a preset payment code information set.
For example, a preset payment code information set is obtained, the payment code information in the preset payment code information set is associated with the identity, and initial payment code information corresponding to the identity of the user is screened out from the preset payment code information set.
310. And the transaction server adopts a preset adjustment strategy to adjust the payment amount, and updates the initial payment code information according to the adjusted payment amount to obtain the payment code information of the current transaction.
For example, the transaction server may randomly decrease the payment amount by using a preset payment adjustment policy, such as a random decreasing policy, to obtain an adjusted payment amount. And modifying the payment amount corresponding to the payment code into the adjusted payment amount, so as to update the initial payment code information and obtain the payment code information of the current transaction, wherein the payment code information can be the character string information of the payment code.
311. And the transaction server sends the payment code information to the payment terminal.
For example, the transaction server directly sends the payment code information to the payment terminal, and when the internal memory of the payment code information is large or the amount of the payment code information is large, the storage address of the payment code information can be sent to the payment terminal, so that the payment terminal can obtain the payment code information of the current transaction in the internal memory or the cache of the transaction server according to the storage address.
312. And the payment terminal sends the payment code information to the cash register terminal so as to process the current payment information.
For example, the payment terminal encrypts the payment code in the form of HID with the character string of the payment code, and sends the encrypted payment code to the cash register terminal according to the HID protocol, and after receiving the character string of the payment code, the cash register terminal sends the character string of the payment code to a transaction system of a bank, so that the deduction is completed in a bank account corresponding to the user in the payment code, and the deducted money is paid to a cash register account in the payment information. And when the adjusted payment amount is less than the original payment amount, the account of the user only pays the adjusted payment amount, and the difference value between the adjusted payment amount and the original transaction amount is used for carrying out payment operation on the cash register account through the bank account corresponding to the payment server, so that the current payment information is processed.
313. The payment terminal sends a payment inquiry request to the transaction server.
For example, the payment terminal may periodically send a payment inquiry request to the transaction server after sending the payment code information to the cashier terminal to inquire the payment status of the current transaction.
314. And the transaction server returns the payment result information of the current transaction to the payment terminal according to the payment inquiry request.
For example, after receiving the payment inquiry request, the transaction server may send the inquiry request to the bank server, and receive the payment status corresponding to the payment code information of the current transaction fed back by the bank server, where the payment status may include success, failure, and timeout. Taking the preset adjustment policy and the adjusted payment amount as adjustment information of the current transaction, for example, taking the preset adjustment policy as a random decreasing, the original payment amount is 10 yuan, the adjustment amount is 0.5 yuan, and the adjusted amount is 9.5 yuan, the adjustment information may be information such as a random decreasing of 0.5 yuan, and the adjusted payment amount is 9.5 yuan. And taking the adjustment information and the payment state as payment result information of the current transaction, and returning the payment result information to the payment terminal.
315. And the payment terminal displays the payment result information.
For example, after receiving the payment result information, the payment terminal may display the adjustment information of the payment status and the payment amount in the payment result information on the payment page of the current transaction.
In a payment scenario, The transaction information processing system is a face-based payment terminal including The Internet of Things (IoT) and a cash register terminal in a transaction as a whole, The cash register terminal includes ERP software for The transaction and an LED display screen for displaying a transaction amount or other transaction information, and The cash register terminal can be regarded as a POS, wherein a core of The ERP software is a service for receiving a payment code, that is, The ERP software supports information input in The form of HID, a core of The IoT face payment terminal includes a 3D camera, a 2D camera and a service related to a face APP, a transaction server at a rear end is mainly used for face live detection and face recognition and adjustment service for The transaction amount, for example, random subtraction, and The whole architecture can be as shown in fig. 8.
As can be seen from the above, in the embodiment of the present invention, after the payment terminal collects the image of the transaction information displayed by the first transaction terminal, the collected transaction image is identified to obtain the transaction amount of the current transaction, and then, the transaction page of the current transaction is displayed, the transaction page includes the transaction amount and the transaction control, in response to the transaction operation of the transaction control, the facial image of the user is collected, the facial image and the transaction amount are sent to the transaction server, the transaction identification information of the current transaction returned by the transaction server according to the facial image and the transaction amount is received, and the transaction identification information is sent to the first transaction terminal to process the transaction information; according to the scheme, the image of the transaction information is collected, the transaction amount of the current transaction is identified in the transaction image and is displayed in the transaction page, under the condition that the user determines that the transaction amount is accurate, the facial image of the user is collected, the transaction identification information is obtained according to the facial image and the transaction amount, and the transaction information is processed, so that the transaction risk is reduced, and therefore the safety of transaction information processing can be improved.
