[0070] In order to make the purpose, technical scheme and advantages of the embodiments of the present invention more clear, the embodiments of the present invention are further described in detail below in conjunction with the accompanying drawings. Here, the illustrative embodiments of the present invention and their descriptions are used to explain the present invention, but are not intended to limit the present invention. It should be noted that, in the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other arbitrarily.

[0071] Figure 1 is a flow chart of a transaction payment processing method provided by an embodiment of the present invention, such as Figure 1 As shown, the transaction payment processing method provided by the embodiment of the present invention is executed in the main scanning device, including:

[0072] Step R1: Scan the QR code video stream displayed by the scanned device to obtain the public key of the scanned device.

[0073] Step R2: Sending a device synchronization request to the server; the device synchronization request carries the public key of the scanned device, so that the server forwards the device synchronization request to the scanned device according to the public key of the scanned device, so that the scanned device synchronizes the clock of each QR code video frame in the QR code video stream, and adds the transaction related information of the scanned device to each QR code video frame;

[0074] The transaction-related information of the scanned device at least includes a timestamp, a clock synchronization confirmation mark and transaction information.

[0075] Step R3: If it is determined that the clock synchronization confirmation mark has passed the verification, the first recognition results corresponding to each QR code video frame are determined according to the acquisition time corresponding to each QR code video frame and the timestamp, and each first recognition result and the corresponding transaction information are sent to the server, so that the server can feedback the transaction payment processing results to the scanned device according to each first recognition result and the corresponding transaction information.

[0076] In the above step R1, the device scans the QR code video stream displayed by the scanned device to obtain the public key of the scanned device. The device can be a computer device that executes the method, for example, it can include a main scanning device, which can be a mobile phone or tablet computer used by the customer. It should be noted that the acquisition and analysis of data involved in the embodiments of the present invention are authorized by the user.

[0077] The scanned device can be a convenient device used by the bank to serve customer payment, such as a mobile device or a self-service machine, such as Figure 2 As shown, the main scanning device and the scanned device are described. The main scanning device E2 includes a flash light D1 and a camera D2. The flash light D1 is used to flash the flash light, and the camera D2 is used to recognize the QR code video stream.

[0078] The scanned device includes a first display area (corresponding to Figure 2 A2 in the figure shows the second display area (corresponding to Figure 2 in A1).

[0079] The QR code video stream displayed by the scanned device is composed of multiple QR code video frames, which include at least one QR code video frame containing the public key of the scanned device. Since the QR code video stream is continuously refreshed at the frame rate, when a QR code video frame containing the public key of the scanned device is scanned, the public key of the scanned device can be extracted from the QR code video frame.

[0080] In the above step R2, the apparatus sends a device synchronization request to the server; the device synchronization request carries the public key of the scanned device, so that the server forwards the device synchronization request to the scanned device according to the public key of the scanned device, so that the scanned device synchronizes the clock of each QR code video frame in the QR code video stream, and adds the transaction related information of the scanned device to each QR code video frame;

[0081] The transaction-related information of the scanned device includes at least a timestamp, a clock synchronization confirmation mark and transaction information. It is understandable that each scanned device has a corresponding scanned device public key. When the server obtains the scanned device public key, it can uniquely determine the scanned device that interacts with the main scanning device based on the scanned device public key.

[0082] The purpose of clock synchronization is to ensure the accuracy of the generation timestamp of each QR code video frame in each QR code video frame. The clock synchronization confirmation flag can be used to mark whether the clock synchronization of each QR code video frame is completed. When the clock synchronization of all QR code video frames is completed, the clock synchronization confirmation flag can be set to 1; when the clock synchronization of the QR code video frames is not completed, the clock synchronization confirmation flag can be set to 0.

[0083] In order to further ensure the security of transaction information, all transaction information can be split so that each split part corresponds to each QR code video frame respectively and added to the corresponding QR code video frame. Only when all QR code video frames are obtained can the split parts be combined into the entire transaction information.

[0084] The length of the video segment of the QR code video stream can be set independently according to actual conditions.

[0085] In the above step R3, if the device determines that the clock synchronization confirmation flag has passed the verification, the device determines the first recognition result corresponding to each QR code video frame according to the acquisition time and the timestamp corresponding to each QR code video frame, and sends each first recognition result and the corresponding transaction information to the server, so that the server can feedback the transaction payment processing result to the scanned device according to each first recognition result and the corresponding transaction information. Referring to the above description, the clock synchronization confirmation flag can be verified by verifying the flag bit value. For example, when the clock synchronization confirmation flag is set to 1, the clock synchronization confirmation flag passes the verification; when the clock synchronization confirmation flag is set to 0, the clock synchronization confirmation flag fails the verification.

[0086] The determining, according to the acquisition time and the timestamp corresponding to each of the two-dimensional code video frames, the first recognition result corresponding to each of the two-dimensional code video frames, comprises:

[0087] If it is determined that the first time interval between the acquisition time and the timestamp is greater than the first preset time length, the first recognition result is determined to be abnormal; the first preset time length can be set independently according to actual conditions. Since, in the method of the embodiment of the present invention, the main scanning device and the scanned device exchange data through a camera and a flash, and the data transmission speed is equivalent to the speed of light, the time interval between the scanning time and the timestamp of each two-dimensional code video frame is usually relatively close to the speed of light. However, when information is stolen through the network, due to network delay time, the time interval between the reception time of the two-dimensional code video frame obtained by the device through the network and the timestamp of the two-dimensional code video frame is too long. Therefore, it can be determined that if the first time interval is greater than the first preset time length, it means that there is a device that obtains the timestamp through the network, which will prompt that the recognition result is abnormal, and further, a first warning message can be sent to the scanned device.

[0088] If it is determined that the first time interval between the acquisition time and the timestamp is less than or equal to the first preset time length, the first recognition result is determined to be normal. Referring to the above description, it can be determined that if the first time interval is less than or equal to the first preset time length, it means that the device that obtains the timestamp by scanning is the main scanning device, and the recognition result will be prompted to be normal.

[0089] The server receives all the first recognition results and transaction information. If the first recognition result of at least one QR code video frame is abnormal, the transaction payment processing result is abnormal, and the payment transaction can be terminated.

[0090] If the first recognition results of all QR code video frames are normal, the transaction payment processing result is normal, and the payment transaction can be completed.

[0091] The transaction-related information of the scanned device also includes a flash feedback information code; the flash feedback information code can be a group of random character strings, and the flash light can flash this group of random character strings through Morse code.

[0092] Accordingly, after the step of determining the first recognition results corresponding to each of the two-dimensional code video frames, the transaction payment processing method further includes:

[0093] The flash flashing mode is determined according to the flash feedback information code, the flash flashing is controlled according to the flash flashing mode, and the first moment when the flash flashing starts is recorded so that the scanned device can display the flash flashing change information; different flash feedback information codes can correspond to different flash flashing modes, and different flash flashing modes can be reflected in flashing brightness and frequency, etc.

[0094] That is, the flash light can be controlled to flash according to different flash brightness and / or different frequencies. Since the flash light flashes are transmitted at the speed of light, the scanned device can instantly display the flash light flash change information through the second display area for displaying the flash light change.

[0095] The flash flickering change information is identified to obtain a second moment of obtaining the flash flickering change information identification result; the flash flickering change information is identified through a camera, and the identification content includes whether the flash flickering change is the same as the flash flickering mode. Usually, the existing method does not have the relevant technology of tampering with the flash flickering mode. If the flash flickering change is different from the flash flickering mode, it means that there is an abnormality, and a relevant prompt message can be generated.

[0096] If the flash light flickering change is the same as the flash light flickering mode, it means that the flash light flickering change information recognition result is normal.

[0097] Determining second recognition results corresponding to each two-dimensional code video frame according to the second moment and the first moment; determining second recognition results corresponding to each two-dimensional code video frame according to the second moment and the first moment includes:

[0098] If it is determined that the second time interval between the second moment and the first moment is greater than the second preset time length, the second recognition result is determined to be abnormal; the second preset time length can be set with reference to the first preset time length. If a video of transcribing flash flashing occurs, the transcribed video needs to be transmitted through the network. Affected by network delay, the time interval between the second moment and the first moment for obtaining the recognition result of the flash flashing change information is too long. Therefore, it can be determined that if the second time interval is greater than the second preset time length, it means that the flash flashing change information is recognized through the network, and it is not performed in the local main scanning device. It will prompt that the recognition result is abnormal, and a second warning message can be sent to the scanned device.

[0099] If it is determined that the second time interval between the second moment and the first moment is less than or equal to the second preset time length, the second recognition result is determined to be normal. Referring to the above description, it can be determined that if the second time interval is less than or equal to the second preset time length, it means that the flash light flickering change information recognition is completed by the main scanning device, and the recognition result will be prompted to be normal.

[0100] The first recognition result, the second recognition result and the corresponding transaction information corresponding to each QR code video frame are sent to the server, so that the server can feedback the transaction payment processing result to the scanned device according to the first recognition result, the second recognition result and the corresponding transaction information corresponding to each QR code video frame.

[0101] The server receives all first recognition results, all second recognition results and transaction information. If at least one first recognition result or second recognition result of a QR code video frame is abnormal, the transaction payment processing result is abnormal, and the payment transaction can be terminated.

[0102] If the first recognition results and the second recognition results of all QR code video frames are normal, the transaction payment processing result is normal, and the payment transaction can be completed.

[0103] The transaction payment processing method provided by the embodiment of the present invention scans the QR code video stream displayed by the scanned device to obtain the public key of the scanned device; sends a device synchronization request to the server; the device synchronization request carries the public key of the scanned device, so that the server forwards the device synchronization request to the scanned device according to the public key of the scanned device, so that the scanned device performs clock synchronization on each QR code video frame in the QR code video stream, and adds the transaction related information of the scanned device to each QR code video frame; wherein, the transaction related information of the scanned device at least includes a timestamp, a clock synchronization confirmation mark and transaction information; if it is determined that the clock synchronization confirmation mark passes the verification, then according to the acquisition time corresponding to each QR code video frame and the timestamp, the first recognition result corresponding to each QR code video frame is determined, and each first recognition result and the corresponding transaction information are sent to the server, so that the server can feedback the transaction payment processing result to the scanned device according to each first recognition result and the corresponding transaction information, which can ensure the security of transaction payment processing.

[0104] Further, determining the first recognition result corresponding to each of the two-dimensional code video frames according to the acquisition time corresponding to each of the two-dimensional code video frames and the timestamp includes:

[0105] If it is determined that the first time interval between the acquisition time and the timestamp is greater than a first preset time length, the first recognition result is determined to be abnormal; the description may refer to the above embodiment and will not be repeated here.

[0106] If it is determined that the first time interval between the acquisition time and the timestamp is less than or equal to the first preset time length, the first recognition result is determined to be normal. The above embodiment can be referred to for description and will not be repeated here.

[0107] The transaction payment processing method provided by the embodiment of the present invention can ensure the accuracy of the first recognition result.

[0108] Furthermore, the transaction-related information of the scanned device also includes a flash feedback information code; accordingly, after the step of determining the first recognition results corresponding to each of the two-dimensional code video frames, the transaction payment processing method also includes:

[0109] The flash flashing mode is determined according to the flash feedback information code, the flash flashing is controlled according to the flash flashing mode, and the first moment when the flash flashing starts is recorded so that the scanned device can display the flash flashing change information; please refer to the above embodiment for description and no further details will be given.

[0110] The flash light flickering change information is identified to obtain a second moment of obtaining the flash light flickering change information identification result; the description may refer to the above embodiment and will not be repeated here.
