FIG. 1a is a flow diagram of a method for generating a video of a graphic code according to an embodiment of the present application, in which, from a device perspective, an executing subject may be one or more electronic devices; from the program perspective, the execution subject may be a program mounted on these electronic devices, accordingly.
Taking the graphic code video as an example for collecting money, the execution subject of the method can be a mobile terminal such as a smart phone, namely a mobile phoneThe mobile terminal generates a graphic code video for collection; the method may be executed by a payment system (such as cloud flash paymentThe background payment system of the (2) generates a graphic code video by the payment system and then sends the graphic code video to the mobile terminal for the mobile terminal to display the graphic code video.
The flow in fig. 1a may include the following steps 101-103.
Step 101, determining first information to be coded and second information to be coded;
102, encoding the first information to be encoded to obtain an initial graphic code;
and 103, carrying out regional color matching on the initial graphic code according to the second information to be coded to obtain a graphic code video, wherein the shape of the graphic code in each frame of the graphic code video is the shape of the initial graphic code, the patterns in each subarea have the same color, and at least one subarea of at least one frame of graphic code is formed by a color pattern of one color.
The shape of the graphics code is identical for each frame of the graphics code video, the shape of the graphics code being capable of containing the first information to be encoded. The coloring schemes of each region in each frame of graphic code in the graphic code video and the sequences formed by the coloring schemes can contain the second information to be coded. In this way, the graphic code video can contain more information to be encoded.
Based on the method of generating a graphic code video in fig. 1a, some embodiments of the present application further provide some specific implementations and extensions of the method, which are described below.
The initial graphic code may be a bar code or a two-dimensional code of various forms.
In some embodiments, the initial graphic code is an initial two-dimensional code divided into a plurality of positioning areas and a plurality of encoding areas; performing region color matching on the initial graphic code according to the second information to be coded to obtain a graphic code video, wherein the method comprises the following steps: generating an image sequence, wherein each frame of image in the image sequence is the initial two-dimensional code; and respectively setting the patterns in at least one positioning area and/or at least one coding area of at least one frame of image in the image sequence as color patterns of one color according to the second information to be coded.
The second information to be encoded may, for example, comprise a plurality of encoded segments, according to which a color scheme of the two-dimensional code may be determined for each encoded segment.
Referring to fig. 1b, in one example, one two-dimensional code may include 3 positioning regions (labeled A, B and C) and 4 encoding regions (labeled D, E, F and G). The second information to be encoded specifies how the 7 regions are color coded and the order in which the color schemes occur.
For example, in a certain frame of two-dimensional code of the graphic code video, the lines of the four coding regions D, E, F and G are red, green, blue and black, and the pattern colors of the three positioning regions A, B and C are black, so that the information to be coded included in the frame of two-dimensional code can be expressed as follows: black, red, green, blue and black.
For another example, in some embodiments, the positioning area does not participate in encoding, and then, in the previous example, the information to be encoded included in the two-dimensional code of this frame may be expressed as: red, green, blue and black.
For another example, in some embodiments, the location area is used to characterize the position of the start frame of the video of the graphics code, then the pattern of location areas in the start frame is colored and the pattern of location areas in the remaining frames is black.
In some embodiments, however, to accommodate the camera capabilities of the code scanning device (e.g., mobile terminal). In graphic code video, the color scheme is the same for every set number of frames.
For example, in a video of a graphic code, the color schemes of the graphic codes of the 1 st to 30 th frames are the same, and the color schemes of the graphic codes of the 31 st to 60 th frames are the same. And so on.
It should be noted that, the mapping relationship between the code segment in the second information to be encoded and the color scheme of the two-dimensional code may be flexibly set, which is not limited in this application.
It should be noted that, according to the mapping relationship between the coding section and the color scheme of the two-dimensional code, there may be one two-dimensional code or several patterns of two-dimensional codes in the two-dimensional code sequence that are all black.
In some embodiments, the first information to be encoded and the second information to be encoded have a one-to-one correspondence. The second information to be encoded is, for example, information for verifying the first information to be encoded, and the second information to be encoded is, for example, a digital signature of the first information to be encoded. Thus, after the code scanning device obtains the graphic code video, the first information to be coded can be checked according to the second information to be coded.
Referring to FIG. 1c, in one exemplary scenario, a payee user is at a mobile terminalThe APP clicks a button for generating the two-dimension code video of collection, so that the mobile terminal is triggered to start the method for generating the graphic code video. />The APP applies for the collection linkage information from the payment system and applies for the second information to be encoded from the encryption system. The second information to be encoded is ciphertext of the identification information corresponding to the collection link information one by one (the ciphertext can be replaced by plaintext of the identification, and the security is relatively low. The encryption system encrypts the identification information of the collection link information, and the obtained ciphertext has the coding meaning of a color scheme of the two-dimensional code and a sequence of the color scheme. The color matching method of the two-dimensional code is, for example, how the three positioning areas of the first-frame two-dimensional code match, how the three positioning areas of the second-frame two-dimensional code match, how the three positioning areas of the third-frame two-dimensional code match, and so on.
After generating a two-dimension code (as an initial two-dimension code described herein) according to the collection link information, the mobile terminal of the collection user performs color matching on the collection two-dimension code according to the second information to be coded, and synthesizes the multiple two-dimension code images subjected to color matching into a two-dimension code video according to a set sequence.
The two-dimensional code of each frame in the two-dimensional code video has the same shape, and the sign is collection link information.
The color scheme of each frame of two-dimensional code in the two-dimensional code video and the appearance sequence of the color schemes represent ciphertext of the identification of the collection link information.
The terminal device can be in rolling broadcasting when playing the graphic code video, and the middle of the terminal device can be stopped or not stopped. As long as the code scanning device can identify the start frame of the graphic code video.
The graphic code video generated according to the method can contain more abundant information to be coded. The graphic code video obtained based on the method can also play a role in preventing the graphic code video from being stolen. In some application scenarios, the offline merchant's collection two-dimensional code is prohibited from being used on a web page that is stolen to the internet. The prior art is not effective in prohibiting this from happening.
Because the video code is played in the form of video, the mobile terminal can be set, so that the mobile terminal can perform anti-recording setting when playing the graphic code video.
For example, the screen recording function is turned off when the graphic code video is played.
For another example, when the start of the recording function of the playing device is detected, a prompt message is generated to prompt the user to close the recording function, and the graphic code video is subjected to invalidation processing.
And performing invalidation processing on the graphic code video, for example, the equipment playing the collection two-dimensional code video notifies a corresponding payment system to perform invalidation processing on the collection link.
If other video recording devices are used to record the graphic code video displayed by the mobile terminal, the frame frequency of the video recording devices is usually smaller than that of the playing devices, and moire phenomenon exists in the recorded graphic code video, so that decoding failure occurs when the recorded graphic code video is scanned by other devices. Even if the frame frequency of the video recording device is the same as that of the playing device, the cost of the video recording device is too high, which greatly reduces the benefit of stealing the graphic code video.
Referring to fig. 2, embodiments of the present application also provide a method of processing a graphic code video. The method is used for decoding the graphic code video and carrying out subsequent verification processing on information obtained after decoding, and in the process, the execution subject can be one or more electronic devices from the viewpoint of the device; from the program perspective, the execution subject may be a program mounted on these electronic devices, accordingly. The method comprises the following steps.
Step 201, obtaining a graphic code video, wherein the shapes of graphic codes in each frame of the graphic code video are the same, the patterns in each partition in the graphic codes are the same in color, and at least one partition of at least one frame of graphic codes is formed by a color pattern of one color;
202, extracting shape information of the graphic code to obtain an initial graphic code, and decoding according to the initial graphic code to obtain first coding information;
and 203, extracting a coloring scheme of the graphic code video to obtain second coding information.
When the initial graphic code is decoded to obtain the first encoded information, the decoding may be performed according to an existing decoding method.
The second encoded information is derived from the coloring scheme of each frame of the graphic code in the graphic code video and their sequence. Of course, to accommodate the processing power of the code scanning device, the pattern may be the same in the video of the graphic code for every set number of frames.
In some embodiments of the present invention, in some embodiments,
the initial graphic code is an initial two-dimensional code, and the initial two-dimensional code is divided into a plurality of positioning areas and a plurality of coding areas;
extracting the coloring scheme of the graphic code video to obtain second coding information, wherein the second coding information comprises the following steps:
and extracting a sequence formed by coloring information of a positioning area and/or a coding area of the two-dimensional code in the graphic code video to obtain the second coding information.
In combination with fig. 1b, color information of different areas of the two-dimensional code is extracted, the color information is combined into code segments, and the code segments are combined into second code information according to the sequence of the color information.
With continued reference to FIG. 1c, in one exemplary scenario, a payor employs cloud flash payment on a mobile terminalAnd shooting the short video of the cash register in a slow motion mode to read multi-frame two-dimensional codes. And then decoding the shape of any one frame of two-dimensional code to obtain the collection link information, and then sending the collection link information to a payment system for the payment system to check the validity of the collection link information. Furthermore, the mobile terminal of the paying subscriber is +.>The APP reads the color information of the specific area of each frame of the two-dimension code to obtain the sequences of the color information, and sends the sequences of the color information to the encryption system to verify the sequences of the color information. The sequence of color information represents the ciphertext of the identifier corresponding to the checkout link (of course, the ciphertext of the identifier corresponding to the checkout link may also be the plaintext, so that the security may be relatively low).
In this scenario, the reading and decoding of the first and second encoded information are performed on the terminal device of the paying user, and the amount of data transmitted to the payment system and the encryption system is small.
If the result of verification of the received collection link information and the color information sequence by the payment system and the encryption system is passed, the payment system can perform subsequent payment operation according to the payment link information.
If only the payment link information passes the verification, the sequence of the color information (i.e. the ciphertext information of the identification of the payment link information) does not pass the verification, the terminal device prompts the payment user to swipe the code again, or the payment system (equivalent to the payment software on the terminal device) performs measures such as quota on the payment transaction.

Thereby further placing the pay code video in motion.
