[0040] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings. However, it should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present disclosure. In the following detailed description, for the sake of explanation, many specific details are set forth to provide a thorough understanding of the embodiments of the present disclosure. However, obviously, one or more embodiments can also be implemented without these specific details. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present disclosure.

[0041] The terms used herein are only for describing specific embodiments and are not intended to limit the present disclosure. The terms "including", "comprising", etc. used herein indicate the presence of the described features, steps, operations, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, or components.

[0042] All terms used herein (including technical and scientific terms) have the meanings commonly understood by those skilled in the art, unless otherwise defined. It should be noted that the terms used herein should be interpreted as having a meaning consistent with the context of this specification and should not be interpreted in an idealized or overly rigid manner.

[0043] When using expressions such as "at least one of A, B, and C", generally, it should be interpreted according to the meaning commonly understood by those skilled in the art (for example, "a system having at least one of A, B, and C" should include, but is not limited to, a system having only A, only B, only C, having A and B, having A and C, having B and C, and / or having A, B, and C).

[0044] Before revealing the present disclosure in detail, the technical terms involved in the embodiments of the present disclosure are explained one by one:

[0045] Payment code payment: It is a new generation of wireless payment solution based on an account system.

[0046] HSV model: A color model for users, focusing on color representation, such as what color, how deep, and how bright. The parameters of color in the HSV model are: hue (H), saturation (S), and value (V). It is a color space created by A.R. Smith in 1978, also known as the Hexcone Model. (1) Hue: Measured in degrees, with a value range of 0° to 360°, calculated counterclockwise starting from red, where red is 0°, green is 120°, and blue is 240°. Their complementary colors are: yellow is 60°, cyan is 180°, and magenta is 300°. (2) Saturation: Saturation S represents the degree to which a color approaches a spectral color. A color can be regarded as the result of mixing a certain spectral color with white. The larger the proportion of the spectral color, the higher the degree of approaching the spectral color, and the higher the saturation of the color. High saturation means the color is deep and vivid. The white component of the spectral color is 0, and the saturation reaches the highest. Usually, the value range is 0% to 100%, and the larger the value, the more saturated the color. (3) Value: Value represents the brightness of the color. For light source colors, the value is related to the brightness of the light-emitting body; for object colors, this value is related to the transmittance or reflectance of the object. Usually, the value range is 0% (black) to 100% (white). For example, the comparison information of different color models is shown in Table 1 below:

[0050] OpenCV: Open Source Computer Vision (OpenCV), a programming library mainly for real-time computer vision, can efficiently implement computer vision algorithms, and is widely used in image stitching, image denoising, product quality inspection, human-computer interaction, face recognition, action recognition, action tracking, driverless, etc. This library is written in C++ and can be used across platforms and operating systems, supporting Windows, Linux, macOS, FreeBSD, NetBSD, OpenBSD, Android, iOS, BlackBerry, etc., and can be used for free according to the open-source BSD license. OpenCV has rich and powerful processing interfaces for color models such as HSV.

[0051] In the prior art, in the scenario of payment code payment, there is an easy risk of transaction fraud by taking screenshots or screen recordings of the payment code.

[0052] To solve the problems existing in the prior art, embodiments of the present disclosure provide a payment code encryption verification method, which is applied to a payment code encryption verification system. The payment code encryption verification system includes a first terminal, a second terminal, and a payment center, and includes: the first terminal receives a first character feature instruction from the payment center; the first terminal converts the first character feature instruction into an optical wave feature signal based on a preset feature comparison table; the second terminal inversely converts the optical wave feature signal from the first terminal into a second character feature instruction based on the preset feature comparison table; the payment center authenticates the first character feature instruction and the received second character feature instruction based on a preset verification rule; and in the case where the authentication passes, the second terminal executes a preset payment process based on the original payment code from the first terminal.

[0053] In the embodiments of the present disclosure, before or during the original payment code payment process. It is implemented after passing the authentication based on another set of encryption verification processes, which greatly improves the transaction security, avoids the transaction risks of payment code theft and fraud by screenshot or screen recording, and provides an optional solution for large-amount payment transactions of payment codes and even payment code identity recognition.

[0055] As Figure 1A shown, the application scenario 100 according to this embodiment may include terminal devices 101, 102, 103, a network 104, and a server 105. The network 104 is used to provide a medium for communication links between the terminal devices 101, 102, 103 and the server 105. The network 104 may include various connection types, such as wired, wireless communication links, or fiber optic cables, etc.

[0056] Users can use the terminal devices 101, 102, 103 to interact with the server 105 through the network 104 to receive or send messages, etc. Various communication client applications may be installed on the terminal devices 101, 102, 103, such as shopping applications, web browser applications, search applications, instant messaging tools, email clients, social platform software, etc. (only as examples).

[0057] The terminal devices 101, 102, 103 may be various electronic devices with a display screen and supporting web browsing, including but not limited to smart phones, tablet computers, laptop portable computers, and desktop computers, etc.

[0058] Server 105 can be a server that provides various services, such as a background management server (only for example) that supports websites browsed by users using terminal devices 101, 102, and 103. The background management server can analyze and process data such as user requests received, and feedback the processing results (such as web pages, information, or data obtained or generated according to user requests) to the terminal devices.

[0059] It should be understood that Figure 1A the numbers of terminal devices, networks, and servers in

[0060] Figure 1B schematically shows an application scenario diagram of payment code encryption verification according to an embodiment of the present disclosure.

[0061] As Figure 1B shown, according to this embodiment, it includes a first terminal 110, a second terminal 120, and a payment center 130.

[0062] Among them,

[0063] the first terminal 110 is configured to receive a first character feature instruction from the payment center;

[0064] the first terminal 110 is further configured to convert the first character feature instruction into an optical wave feature signal based on a preset feature comparison table;

[0065] the second terminal 120 is configured to inversely convert the optical wave feature signal from the first terminal into a second character feature instruction based on the preset feature comparison table;

[0066] the payment center 130 is configured to authenticate the first character feature instruction and the received second character feature instruction based on a preset verification rule; and

[0067] the second terminal 120 is further configured to execute a preset payment process based on the original payment code from the first terminal in the case of successful authentication.

[0068] It can be understood that only instructions (or signals) can be sent from the first terminal 110 to the second terminal 120.

[0069] The following will be based on Figure 1A the described scenario and Figure 1B the described system, and will describe the payment code encryption verification method of the disclosed embodiment in detail through Figures 2 - 8

[0070] Figure 2The flowchart of a payment code encryption verification method according to an embodiment of the present disclosure is schematically shown.

[0071] As Figure 2 shown, the payment code encryption verification method of this embodiment includes operations S210 to S250. This payment code encryption verification method can be applied to a payment code encryption verification system, which includes a first terminal, a second terminal, and a payment center.

[0072] In operation S210, the first terminal receives a first character feature instruction from the payment center.

[0073] Among them, for the first character feature instruction, it is generated by the payment center based on its own generation logic.

[0074] According to an embodiment of the present disclosure, before the first terminal receives the first character feature instruction from the payment center, it further includes: the payment center encrypts a preset first verification information based on a preset encryption algorithm to obtain the first character feature instruction.

[0075] Specifically, the payment center combines elements such as business branches, scenarios, channels, importance, merchant-customer binding relationships, etc. according to a certain algorithm as the actual meaning of the first character feature instruction, that is, the first verification information. On this basis, the above first verification information is encrypted to be updated as the first character feature instruction, where the encryption method can be public key encryption and / or private key encryption. For example, the first verification information at least includes transaction type, generation timestamp, validity period, and other business-related fields. The first character feature instruction is obtained by encrypting the first verification information, which increases the security of the first character feature instruction.

[0076] It can be understood that the above preset encryption algorithm can be any common encryption algorithm in the prior art. For example, the preset encryption algorithm can be a symmetric algorithm. It is not limited here.

[0077] In operation S220, the first terminal converts the first character feature instruction into a light wave feature signal based on a preset feature look-up table.

[0078] Specifically, the conversion of the first character feature instruction into a light wave feature signal can be achieved by means of code (in the form of apk or api) in cooperation with OpenCV to control the first terminal (such as terminal devices such as mobile phones, tablets, and self-service terminals), and convert the first character feature instruction into a light wave feature signal.

[0079] Among them, the preset feature comparison table is generated by the payment center and pre-stored in the first terminal and the second terminal. The preset feature comparison table includes comparison information of light wave features and character features, and the preset feature comparison table can be updated / maintained irregularly (or periodically).

[0080] According to an embodiment of the present disclosure, among them, the light wave feature signal includes a static light wave feature signal and a dynamic light wave feature signal. The static light wave feature signal includes light wave color and light wave region, and the dynamic light wave feature signal includes light wave color, light wave region, and light wave flicker frequency.

[0081] For example, the preset feature comparison table is shown in Table 2 below:

[0082] Optical wave characteristics Characteristics of characters Red 1 Yellow 2 Green 3 Cyan 4 Blue 5 Magenta 6 White 7 Black 8 Upper screen A Lower screen B

[0083] Table 2

[0084] It can be understood that Table 2 above schematically shows the comparison information of the light wave features in the static light wave feature signal and the character features in the first character feature instruction (or the second character feature instruction). Table 2 only includes light wave color information (i.e., red, yellow, green, cyan, blue, magenta, white, and black), and light wave region (i.e., the upper screen and the lower screen). Furthermore, the light wave feature signal generated by the conversion of the first character feature instruction is a static image, where the light wave color information and the light wave region information can be set according to specific situations. For example, the light wave color information can be classified more precisely according to color light, colorant, and HSV information. Another example is that the screen can be divided into a four-screen or an eight-screen, which will not be elaborated here.

[0085] Another example, the preset feature comparison table is shown in Table 3 below:

[0086] Meaning Transcoding Red 1 Yellow 2 Green 3 Cyan 4 Blue 5 Magenta 6 White 7 Black 8 Long A Short B Upper screen C Lower screen D

[0087] Table 3

[0088] It can be understood that the above Table 3 schematically shows the comparison information between the light wave characteristics in the dynamic light wave characteristic signal and the character characteristics in the first character characteristic instruction (which can also be the second character characteristic instruction). Table 3 includes light wave color information (i.e., red, yellow, green, cyan, blue, magenta, white, and black), light wave area (i.e., upper screen and lower screen), and light wave flashing frequency. Furthermore, the light wave characteristic signal generated by the conversion of the first character characteristic instruction is a dynamic image, where the light wave color information, light wave area information, and can be set according to specific circumstances. For example, the light wave color information can be classified more precisely according to color light, colorant, and HSV information. For another example, the screen can be divided into four screens or eight screens. For still another example, multiple different meanings can be defined for the light wave flashing frequency by the flashing duration (for example, if the flashing duration exceeds 0.3 seconds, it is the first duration; if the flashing duration is between 0.3 and 0.2 seconds, it is the second duration; if it is less than 0.2 seconds, it is the third duration).

[0089] Taking the corresponding relationship in the above Table 3 as an example, a large number of different random combinations can be generated. For example, if the first character characteristic instruction is "CB1B2B3B4B5B6B7B8D1A2A3A4A5A6A7A8A", the instruction for displaying the dynamic light wave characteristic signal correspondingly is: for the upper half screen, red, yellow, green, cyan, blue, magenta, white, black, and they are switched and displayed in the order of short respectively; for the lower half screen, red, yellow, green, cyan, blue, magenta, white, black, and different colors can be switched and displayed in the order of long or short respectively.

[0090] Of course, since the light waves in the light wave characteristic signal are divided into regions, the recognition order of different regions in the light wave characteristic signal can also be diverse. If the recognition is not carried out in the pre-agreed order, the recognized second character characteristic instruction is also incorrect.

[0091] According to an embodiment of the present disclosure, the second terminal reversely converts the light wave characteristic signal from the first terminal into a second character characteristic instruction based on the preset characteristic comparison table, including: based on the preset characteristic comparison table, converting the light wave color through a preset region conversion order, or based on the preset characteristic comparison table, converting the light wave color and the light wave flashing frequency through the preset region conversion order.

[0092] Among them, the preset region conversion order can be generated by the payment center and sent to the first terminal and the second terminal in advance, and can be updated irregularly (or periodically).

[0093] It should be noted that when the first terminal converts the first character characteristic instruction into a light wave characteristic signal, it is also based on the above preset region conversion order. Details are not described herein again.

[0094] It is understandable that the static light wave characteristic signal is different from the dynamic light wave characteristic signal. The static light wave characteristic signal is a static image, while the dynamic light wave characteristic signal is a dynamic image (due to the light wave flashing frequency). And the dynamic light wave characteristic signal is played periodically. Therefore, it is not possible to randomly intercept the dynamic light wave characteristic signal in a certain time period for conversion operation and then use it as the second character feature instruction for authentication. Therefore, it is necessary to intercept by setting the start bit and the end bit.

[0095] According to an embodiment of the present disclosure, after the second terminal reversely converts the light wave characteristic signal from the first terminal into a second character feature instruction based on the preset feature comparison table, it further includes: intercepting the characters from the start bit to the end bit of the second character feature instruction to complete the update of the second character feature instruction.

[0096] In the embodiment of the present disclosure, since the dynamic light wave instruction is dynamic, it is necessary to intercept the information between the start bit and the end bit to ensure that the obtained dynamic light wave characteristic signal is valid.

[0097] In operation S230, the second terminal reversely converts the light wave characteristic signal from the first terminal into a second character feature instruction based on the preset feature comparison table.

[0098] Specifically, the light wave characteristic signal can be decrypted through the interface of OpenCV and reversely converted according to the above preset feature comparison table to inversely deduce the second character feature instruction.

[0099] In operation S240, the payment center authenticates the first character feature instruction and the received second character feature instruction based on a preset verification rule.

[0100] Taking the dynamic light wave characteristic signal as an example, when parsing and inversely deducing through the light wave characteristic signal, a second character feature instruction "CB1B2B3B4B5B6B7B8D1A2A3A4A5A6A7A8A" is obtained.

[0101] It is understandable that based on a large number of different types of light wave characteristics in the light wave characteristic signal, corresponding to a large number of different types of character characteristics, and then through the permutation and combination of a large number of different types of character characteristics, a highly confidential character feature instruction (or key) is realized. It can play the greatest role in the 5G scenario with high network coverage and low latency.

[0102] Of course, it is also necessary to decrypt the second character feature instruction to obtain the actual information contained in the second character feature instruction, that is, the second verification information.

[0103] Figure 3A flowchart of a payment code encryption verification method according to the present disclosure is schematically shown.

[0104] As Figure 3 shown, the payment code encryption verification method of this embodiment corresponds to operation S240, and this payment code encryption verification method includes operations S310 to S320.

[0105] In operation S310, based on the preset encryption algorithm, the second character feature instruction is parsed to obtain second verification information.

[0106] In operation S320, based on a preset verification rule, it is verified whether the second verification information is legal.

[0107] Specifically, for example, the second verification information obtained by decryption includes at least a transaction type, a generation timestamp, a validity period, and other service-related fields.

[0108] Of course, there are various above-mentioned preset verification rules, which will be explained in detail below.

[0109] Figure 4 A flowchart of a payment code encryption verification method according to the present disclosure is schematically shown.

[0110] As Figure 4 shown, the payment code encryption verification method of this embodiment includes operations S410 to S430,

[0111] In operation S410, the consistency between the second verification information and the first verification information is verified.

[0112] Specifically, it is checked whether the character information of the second verification information and the first verification information is consistent.

[0113] In operation S420, the transaction types of the first verification information and the second verification information are verified.

[0114] Specifically, different transaction types correspond to different transaction rules. It is verified whether this verification type can be implemented through the payment code under the specific transaction rules.

[0115] In operation S430, it is verified whether the valid time of the second verification information exceeds a preset valid time.

[0116] Specifically, the starting point of the timing of the preset valid time can be the time when the first verification information is generated, or it can also be the time when the first character feature instruction is generated. And the ending point of the timing can be the time when the second character feature instruction is received, or the time when the second character verification information is obtained. Details are not described herein again.

[0117] In an embodiment of the present disclosure, through multiple single verification methods or a combination of multiple verification methods, the legality of the second verification information is accurately ensured, and further the security of the original payment code verification is ensured.

[0118] Of course, when verifying the second verification information, there is also another efficient method.

[0119] Figure 5 A flowchart of a payment code encryption verification method according to the present disclosure is schematically shown.

[0120] As Figure 5 shown, the payment code encryption verification method of this embodiment includes operation S510 to operation S520.

[0121] In operation S510, the payment center obtains the identification status bit corresponding to the second verification information.

[0122] In operation S520, it is judged whether the identification status bit is unused.

[0123] For example, identification status bits related to the first verification information and the second verification information are reserved in the payment center. When the second verification information is verified, the identification status bit changes (for example, from 0 to 1, where 0 is unused and 1 is used or used once).

[0124] In an embodiment of the present disclosure, by verifying the usage status of the payment code, it is possible to effectively prevent re - authentication after the optical wave feature signal has been stolen by others.

[0125] It can be understood that the above operations S510 to S520 can be single - executed verification operations or verification operations combined with the above operations S410 to S430. There is no limitation here.

[0126] In operation S250, when the authentication is passed, the second terminal executes a preset payment process based on the original payment code from the first terminal.

[0127] Specifically, the preset payment process can be understood as the transaction code payment process in the prior art, such as the payment process of two - dimensional codes, etc. Details are not described herein again.

[0128] It can be understood that relevant information about different character feature instructions (for example, multiple first character feature instructions) will be saved in the payment center. After receiving the second character feature instruction, the corresponding first character feature instruction will be searched, and then, through a preset verification rule, the relevant information of the first character feature instruction and the second character feature instruction will be verified. Therefore, the above operations S210 to S250 can be regarded as an additional encryption verification process outside the original original payment code payment.

[0129] Of course, for the process of executing payment with the original payment code in the prior art, it can be serially executed with the above operations S210 to S250, that is, after the above operations S210 to S250 are completed and a pass instruction is received in the payment code verification system, the process of executing payment with the original payment code is started. Similarly, the process of executing payment with the original payment code in the prior art can also be executed in parallel with the above operations S210 to S250.

[0130] According to an embodiment of the present disclosure, the timing for the second terminal to receive the original payment code includes: in the case of successful authentication, the second terminal receives the original payment code from the first terminal, or after the first terminal converts the first character feature instruction into an optical wave feature signal based on a preset feature comparison table, the second terminal receives the original payment code from the first terminal.

[0131] Among them, the above "in the case of successful authentication, the second terminal receives the original payment code from the first terminal" is serially executed with the preset payment process. After successful authentication, the first terminal generates a payment code and sends it to the second terminal.

[0132] Among them, the above "after the first terminal converts the first character feature instruction into an optical wave feature signal based on a preset feature comparison table, the second terminal receives the original payment code from the first terminal" is in a parallel state with the preset payment process, that is, after the above operation S220, the payment code generated by the first terminal is sent to the second terminal.

[0133] According to an embodiment of the present disclosure, after the first terminal converts the first character feature instruction into an optical wave feature signal based on a preset feature comparison table, the second terminal receives the original payment code from the first terminal, including: the second terminal receives a combined payment code, where the combined payment code is generated by combining the original payment code and the optical wave feature signal.

[0134] The original payment code and the optical wave feature signal can be sent one after the other or together.

[0135] Figure 6 Schematically shows a schematic diagram of combining an optical wave feature signal and an original payment code according to the present disclosure.

[0136] As Figure 6 shown, the optical wave feature signal and the original payment code are in different regions. The first region of the optical wave feature signal is the second region surrounding the original payment code. Combining the images of these two regions forms a new image. During the data transmission process, the image of the region of the optical wave feature signal can be static, or can be flashing or dynamic.

[0137] It can be understood that combining and sending the optical wave feature signal and the original payment code is equivalent to embedding the optical wave feature signal in the original payment code in the original transaction execution process of the original payment code. Therefore, it will not cause an intrusive change to the original transaction execution process of the original payment code, which is beneficial to the transformation based on the existing payment code payment process.

[0138] In the embodiments of the present disclosure, before the original payment code payment process, or during the original payment code payment process. It is implemented after passing the authentication through another set of encryption verification processes, greatly improving the transaction security, avoiding the transaction risk of being stolen by taking screenshots or screen recordings of the payment code, and providing an optional solution for large-amount payment transactions of the payment code and even payment code identity recognition.

[0139] Figure 7 Schematically shows a full flow chart of a payment code encryption verification method according to the present disclosure.

[0140] As Figure 7 shown, the payment code encryption verification method of this embodiment includes operations S701 to S711.

[0141] In operation S701, the first terminal sends a character generation request to the payment center.

[0142] In operation S702, the payment center generates a first character feature instruction in response to the payment code encryption verification instruction.

[0143] In operation S703, the payment center sends it to the first terminal.

[0144] In operation S704, the first terminal generates an optical wave feature signal for the received first character feature instruction.

[0145] In operation S705, the first terminal generates an original payment code, and combines the optical wave feature signal and the original payment code and sends them to the second terminal.

[0146] In operation S706, the second terminal analyzes the optical wave feature signal to obtain a second character feature instruction.

[0147] In operation S707, the second terminal sends the second character feature instruction to the payment center.

[0148] In operation S708, the payment center verifies the signature (or authenticates) the second character feature instruction. If the signature verification passes, operation S780 is executed; if the signature verification fails, operation S710 is executed.

[0149] In operation S709, the payment center generates a signature verification passed instruction and sends it to the second terminal.

[0150] In operation S710, the second terminal performs a payment code payment process based on the original payment code to complete this payment code transaction.

[0151] Based on the above payment code encryption and verification method, the present disclosure also provides a payment code encryption and verification system. The following will be combined with Figure 8 to describe this system in detail.
