It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.
Fig. 1a is a schematic flowchart of a method for generating a graphic code video according to an embodiment of the present application, where from a device perspective, an execution subject may be one or more electronic devices; from the program perspective, the execution main body may accordingly be a program loaded on these electronic devices.
Taking the graphic code video for collection as an example, the execution main body of the method can be a mobile terminal such as a smart phone, namely, the mobile terminal generates the graphic code video for collection; the execution subject of the method may also be a payment system (e.g. be
The background payment system) generates the graphic code video by the payment system and then sends the graphic code video to the mobile terminal, so that the mobile terminal can display the graphic code video.
The flow in fig. 1a may comprise the following steps 101 to 103.
102, encoding the first information to be encoded to obtain an initial graphic code;
103, performing 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 in the graphic code video is the shape of the initial graphic code, the colors of the patterns in each region are the same, and at least one region of at least one frame of the graphic code is formed by a color pattern with one color.
The shape of each frame of the graphic code video is the same, and the shape of the graphic code can contain the first information to be encoded. The coloring scheme of each region in each frame of graphic code in the graphic code video and the sequence formed by the coloring schemes can contain second information to be coded. Thus, the graphic code video can contain more information to be encoded.
Based on the method for generating the graphic code video in fig. 1a, some embodiments of the present application also provide some specific embodiments of the method, and an extension scheme, which are described below.
The initial graphic code can be a bar code or a two-dimensional code in various forms.
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; performing regional color matching on the initial graphic code according to the second information to be coded to obtain a graphic code video, including: generating an image sequence, wherein each frame of image in the image sequence is the initial two-dimensional code; and setting patterns in at least one positioning area and/or at least one encoding area of at least one frame of image in the image sequence as a color pattern of one color respectively according to the second information to be encoded.
The second information to be coded may, for example, comprise a plurality of code segments, from each of which a color scheme of the two-dimensional code may be determined.
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 to be color-coded, and the front-to-back order in which the color schemes appear.
For example, in a frame of two-dimensional code of a graphic code video, lines of four encoding regions D, E, F and G are red, green, blue and black, respectively, and pattern colors of three positioning regions A, B and C are all black, then information to be encoded contained in the frame of two-dimensional code can be represented as: black, red, green, blue and black.
For another example, in some embodiments, the positioning area does not participate in encoding, and then following the previous example, the information to be encoded included in the frame of the two-dimensional code may be represented as: red, green, blue and black.
For another example, in some embodiments, the anchor region is used to characterize the position of the starting frame of the graphic code video, and then the pattern of anchor regions in the starting frame is colored and the pattern of anchor regions in the remaining frames is black.
And in some embodiments to accommodate the camera capabilities of a camera of a code scanning device, such as a mobile terminal. In graphic code video, the color scheme is the same for every set number of frames.
For example, in the graphic code video, the color schemes of the graphic codes of the 1 st frame to the 30 th frame are the same, and the color schemes of the graphic codes of the 31 st frame to the 60 th frame are the same. And so on.
It should be noted that, the mapping relationship between the coding segment in the second information to be coded 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 code segments and the color schemes of the two-dimensional codes, in the two-dimensional code sequence, there may be one two-dimensional code or several two-dimensional codes with black patterns.
In some embodiments, the first information to be encoded and the second information to be encoded are in a one-to-one correspondence relationship. 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. Therefore, after the code scanning device obtains the graphic code video, the first information to be coded can be verified according to the second information to be coded.
Referring to FIG. 1c, in one exemplary scenario, the payee is at the mobile terminal
The APP clicks a button for generating the two-dimensional code video, so that the mobile terminal is triggered to start the method for generating the graphic code video.
The APP applies for the payment link information from the payment system and applies for the second information to be coded from the encryption system. The second information to be coded is linked with the collectionThe information is encrypted with identification information corresponding to each other (or replaced with the plaintext of the identification, which is of course relatively low in security). Namely, the encryption system encrypts the identification information of the collection link information, and the coding meaning of the obtained ciphertext is the color scheme of the two-dimensional code and the sequence of the color scheme. The color matching method of the two-dimension code is, for example, how the three positioning areas of the first frame of the two-dimension code are matched in color, how the three positioning areas of the second frame of the two-dimension code are matched in color, how the three positioning areas of the third frame of the two-dimension code are matched in color, and so on.
After the mobile terminal of the payee generates a payee two-dimensional code (as the initial two-dimensional code) according to the payee link information, color matching is performed on the payee two-dimensional code according to the second information to be coded, and a plurality of two-dimensional code images subjected to color matching are combined into a two-dimensional code video according to a set sequence.
The two-dimensional codes in each frame in the two-dimensional code video are identical in shape, and the characteristic is collection link information.
The color schemes of the frames of the two-dimensional code in the two-dimensional code video and the appearance sequence of the color schemes represent the ciphertext of the identification of the collection link information.
When playing the graphic code video, the terminal equipment can be played in a rolling way, and the middle of the terminal equipment can be paused or not paused. As long as the code scanning device can identify the starting frame of the graphic code video.
The graphic code video generated by the method can contain richer information to be coded. The graphic code video obtained based on the method can also have the effect of preventing the graphic code video from being stolen. In some application scenarios, the two-dimensional code for payment collection of the offline merchant is prohibited from being stolen for use on a webpage of the internet. The prior art does not effectively prohibit this from occurring.
Because the video code is played in a video form, the mobile terminal can be set, so that the mobile terminal can perform screen recording prevention setting when playing the graphic code video.
For example, the screen recording function is closed when the graphic code video is played.
For another example, when it is detected that the screen recording function of the playing device is turned on, prompt information is generated to prompt the user to turn off the screen recording function, and the graphic code video is subjected to invalidation processing.
And performing invalidation processing on the graphic code video, for example, notifying a corresponding payment system to perform invalidation processing on the collection link by a device playing the collection two-dimensional code video.
If other video recording devices are adopted to record the graphic code video displayed by the mobile terminal, because the frame frequency of the video recording device is usually less than that of the playing device, moire phenomenon exists in the recorded graphic code video, which results in that the decoding of the recorded graphic code video fails when the other devices scan codes. 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, and the benefit of appropriating the graphic code video is greatly reduced.
Referring to fig. 2, an embodiment of the present application further provides a method for processing a graphic code video. The method is used for decoding the graphic code video and performing subsequent verification processing on information obtained after decoding, and in the process, from the equipment perspective, an execution main body can be one or more electronic equipment; from the program perspective, the execution main body may accordingly be a program loaded on these electronic devices. The method comprises the following steps.
and 203, extracting the 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 coding information can be obtained according to the coloring scheme of each frame of the graphic code in the graphic code video and the sequence of the frames. Of course, in order to adapt to the processing capability of the code scanning device, the pattern of each set number of frames in the graphic code video can be the same.
In some embodiments of the present invention, the,
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:
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.
And (3) extracting color information of different areas of the two-dimensional code by combining with the graph 1b, combining the color information into coding segments, and combining the coding segments into second coding information according to the sequence of the color information.
With continued reference to FIG. 1c, in one exemplary scenario, the paying user employs a mobile terminal
The APP carries out slow motion shooting on the short video of the cash register code and reads the multi-frame two-dimensional code. And then decoding the shape of any frame of two-dimensional code to obtain collection link information, and then sending the collection link information to a payment system so that the payment system can check the validity of the collection link information. In addition, of paying subscriber's mobile terminal
The APP reads the color information of the specific area of each frame of the two-dimensional code to obtain the sequence of the color information, and sends the sequence of the color information to the encryption system to check the sequence of the color information. The sequence of color information represents the ciphertext of the identifier corresponding to the collection link (or the plaintext of the identifier corresponding to the collection link, which may be relatively less secure).
In this scenario, the reading and decoding of the first encoded information and the second encoded information are both 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 payment system and the encryption system verify the received sequence of the collection link information and the color information, the payment system can perform subsequent payment operation according to the payment link information.
