Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

As shown in Figure 1, an embodiment of the present invention provides a method for verifying a picture verification code, which includes:

Step 110, select a picture from a preset gallery, and generate a verification code according to the picture. The form of the verification code is variable, and the verification code forms a picture in a specific form. In this embodiment, there is no limitation on how to generate the verification code. For example, the picture may be divided into puzzle-shaped verification codes, and the number of pieces of the puzzle is not limited.

Step 120, receiving the user's verification operation, and changing the form of the verification code according to the verification operation. For example, based on the aforementioned puzzle-style verification code, the user's verification operation is the splicing operation of the verification code.

Step 130, select the first area from the modified verification code and extract the image information of the first area.

Step 140, select the second area from the picture and extract the image information of the second area, the position of the second area on the picture corresponds to the position of the first area on the verification code.

According to the technical solution of this embodiment, when comparing the verification code and the picture, it is not to compare the entire image information of the verification code and the picture, but to extract the image of the partial area corresponding to the position for comparison, because the extracted image The information becomes less, so the comparison efficiency of the extracted image information becomes higher, so that it is possible to quickly judge whether the verification is successful.

As shown in Figure 2, an embodiment of the present invention provides a method for verifying a picture verification code, which includes:

Step 210, acquiring external pictures outside the gallery, and updating pictures in the gallery. In this embodiment, by updating the pictures in the gallery, the generated verification codes can be continuously changed, so that the verification methods of the verification codes will not be completely collected, avoiding verification by machines through enumeration.

Specifically, according to the application using the verification code, the webpage corresponding to the application can be selected and the external picture can be acquired from the webpage. For example, if the verification code is used in a mobile game, extract pictures from the official web page of the mobile game and add them to the gallery, which can enhance the association between the verification code and the application, making it easier to use the verification code. understood by users of the application.

Further, a picture with a difference between the publishing time and the current time within a preset threshold may be selected from the webpage as the external picture. For example, a picture within one week of the current time difference can be selected; through the technical solution of this embodiment, it can be guaranteed that the acquired picture is a newer picture, and the verification code generated by the newer picture is not easy to be recognized by a machine.

Step 220, select a picture from a preset gallery, select a generation method from a variety of preset methods for generating a verification code, and generate a verification code according to the selected generation method, the form of the verification code is variable, and the verification code Form a picture in a specific shape.

Step 240, select the first area from the modified verification code and extract the image information of the first area.

Step 250, select the second area from the picture and extract the image information of the second area, the position of the second area on the picture corresponds to the position of the first area on the verification code.

In step 260 , after denoising the first area and the second area to the same degree, the color information is extracted for comparison. In the technical solution of this embodiment, after a certain degree of noise reduction, the mid-color in the first area and the second area will be eliminated, leaving only black and white. At this time, the extracted color information will be less and easier Compare.

Step 320, receiving the user's verification operation, and changing the form of the verification code according to the verification operation.

Step 330, select the first area from the modified verification code and extract the image information of the first area.

Step 340, according to the position of at least one movable part in the verification code after the user performs the verification operation, determine and select the position of the selected first area on the verification code. In the technical solution of this embodiment, if the verification code is different from the picture, the position of at least one movable part of the verification code is incorrect, so the first region can be selected based on the position of the movable part on the verification code. For example, in the picture verification code shown in Figure 4, 410 is a movable part, and the position of the dotted line frame is the correct position of the movable part 410, then according to the technical solution of the embodiment itself, the selected first area May be shaded portion 420 .

Or, according to the position of at least one movable part when the verification code forms a picture, determine and select the position of the selected first area on the verification code. Similarly, based on the aforementioned content, the first area can also be selected according to the correct position of the movable part.

And the verification code forms a picture in a specific form. In this embodiment, for the same gallery picture, multiple verification codes can be generated through different generation methods. It can be seen that the technical solution of this embodiment is conducive to enriching the types of verification codes and making it more difficult to crack the verification codes.

The verification operation module 630 receives the user's verification operation, and changes the form of the verification code according to the verification operation.

The first area extracting module 640 selects the first area from the modified verification code and extracts the image information of the first area.

The second area extracting module 650 selects the second area from the picture and extracts the image information of the second area. The position of the second area on the picture corresponds to the position of the first area on the verification code.

The image information comparison module 660 extracts color information for comparison after denoising the first area and the second area to the same degree.
