Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention. On the contrary, the embodiments of the invention include all changes, modifications and equivalents coming within the spirit and terms of the claims appended hereto.

Fig. 1 is a schematic flow chart of a method for generating a dynamic verification code picture according to an embodiment of the present invention, where the method includes:

s11: the method comprises the steps of obtaining at least two frames of static verification code pictures, wherein each frame of static verification code picture comprises a first sub-picture and a second sub-picture, the first sub-picture is a sub-picture where a verification code is located, the second sub-picture is a sub-picture where a background is located, the first sub-picture comprises first display content, the second sub-picture comprises second display content, and the first display content and the second display content display the verification code after being played.

The static verification code picture of each frame can be obtained by splicing a first sub-picture and a second sub-picture which are obtained in advance; or, the verification code picture can be obtained by dividing the area to be occupied by the verification code picture and filling corresponding contents; alternatively, the information may be directly generated according to a preset program.

The area occupied by each sub-picture may be regular, for example, referring to fig. 2, the area to be occupied by the captcha picture is divided into 5 rows and 3 columns of sub-areas, and each sub-picture occupies one of the sub-areas. Or,

the area occupied by each sub-picture may be irregular, e.g. see fig. 3, the size of the sub-areas being different.

The position of the first sub-picture may be preset, and when actually set, a specific position value, for example, a specific horizontal and vertical coordinate value, may be set. Or,

it is also possible to set a position interval and then randomly select the position interval, for example, set the interval value of the horizontal and vertical coordinates and randomly select the position interval.

It can be understood that the preset position interval has a positive correlation with the sum of the numbers of the first sub-picture and the second sub-picture. For example, the larger the number of sub-pictures included in each frame of static verification code picture, the larger the preset position interval may be, that is, the character to be displayed may float in a larger range.

Referring to fig. 4 and 5, taking the character to be displayed as "8" for example, two different position effects are given by randomly choosing the position of the first sub-picture within the position interval.

In addition, in fig. 4 and 5, the sub-picture occupied by "8" is the first sub-picture, and the remaining blank sub-pictures are the second sub-pictures.

Wherein, in the same frame,

the first display content is the same at different positions, the second display content is the same at different positions, and the first display content and the second display content are the same; or,

the first display content is different at different locations; or,

the second display content is different at different locations.

In the different frames, it is possible to have,

the first display contents are the same or different; and/or the presence of a gas in the gas,

the second display contents are the same or different.

For example, referring to fig. 6, in the same frame, taking the first display content as an example, the number "1" may be in some sub-pictures, and the letter "L" may be in other sub-pictures (for easier distinction, L is used to replace L in fig. 6); alternatively, the first display content is all gears, but the number of gears in different positions is different, for example, gears with three teeth in some positions, gears with four teeth in other positions, and the like.

In addition, the display content in different frames may be the same or different. Still taking the first display content as an example, the number "1" may be in one frame and the letter "L" (lower case L) may be in another frame.

In this embodiment, taking the example that the first display content and the second display content are both numbers "1", since the first display content and the second display content are the same in the same frame, the machine cannot recognize the verification code even if capturing a frame of picture.

S12: and playing the static verification code picture to obtain a dynamic verification code picture, wherein a first dynamic content is obtained according to the first display content during playing, a second dynamic content is obtained according to the second display content, and the first dynamic content and the second dynamic content have different dynamic information.

The static verification code picture can be played frame by frame to obtain a dynamic verification code picture.

Through playing, dynamic display content can be obtained, the first dynamic content and the second dynamic content have different dynamic information, and the verification code which can be identified by human eyes is obtained.

For example, referring to fig. 7, "1" in the first display content is rotated clockwise with the center point, and "1" in the second display content is rotated counterclockwise with the center point.

Because the rotation directions of the two are different, human eyes can distinguish the two, and the displayed character is '8'. However, the machine can only capture static content, that is, when the machine captures a static verification code, the machine sees all the content of "1" and cannot see that the displayed character is "8", thereby reducing the success rate of automatic recognition of the machine.

It is to be understood that the dynamic information is not limited to direction, but may be different in frequency and/or different in motion. For example, the first display content and the second display content are both rotated clockwise, but the frequency of rotation is different; and/or the first display content is panned and the second display content is rotated.

In addition, the static verification code picture further comprises a third sub-picture, the third sub-picture is a sub-picture where the interference point is located, the third sub-picture comprises third display content, third dynamic content is obtained according to the third display content when the third sub-picture is played frame by frame, and the third dynamic content and the first dynamic content have the same dynamic information.

Optionally, the third display content is the same or different in the same frame; or,

the third display content is the same or different in different frames; or,

the third display content is the same as or different from the first display content and/or the second display content in the same frame.

In the embodiment, the sub-picture where the verification code is located and the sub-picture where the background is located are distinguished, the sub-picture where the verification code is located and the sub-picture where the background is located have different motion information to realize the identification of the verification code by human eyes, in addition, the verification code is displayed only after the first display content in the sub-picture where the verification code is located and the second display content in the sub-picture where the background is located are played frame by frame, and the verification code cannot be identified when a single frame is used, so that the success rate of automatic identification of a machine can be reduced, the risk of cracking the verification code is reduced, and the network safety is improved. In addition, compared with the methods of blurring, warping, adding noise and the like generally used by static verification code pictures, the present embodiment may not perform the processing of blurring, warping, adding noise and the like, and may improve the user experience.

The having different states, including:

translation of the verification code occurs; or,

stretching the verification code; or,

s11': the method comprises the steps of obtaining at least two frames of static verification code pictures, wherein each frame of static verification code picture comprises a first sub-picture and a second sub-picture, the first sub-picture is a sub-picture where a verification code is located, the second sub-picture is a sub-picture where a background is located, the first sub-picture comprises first display content, the second sub-picture comprises second display content, and the first display content and the second display content display the verification code after being played.

The static verification code picture of each frame can be obtained by splicing a first sub-picture and a second sub-picture which are obtained in advance; or, the verification code picture can be obtained by dividing the area to be occupied by the verification code picture and filling corresponding contents; alternatively, the information may be directly generated according to a preset program.

The area occupied by each sub-picture may be regular, for example, referring to fig. 2, the area to be occupied by the captcha picture is divided into 5 rows and 3 columns of sub-areas, and each sub-picture occupies one of the sub-areas. Or,

the area occupied by each sub-picture may be irregular, e.g. see fig. 3, the size of the sub-areas being different.

The position of the first sub-picture may be preset, and when actually set, a specific position value, for example, a specific horizontal and vertical coordinate value, may be set. Or,

it is also possible to set a position interval and then randomly select the position interval, for example, set the interval value of the horizontal and vertical coordinates and randomly select the position interval.

It can be understood that the preset position interval has a positive correlation with the sum of the numbers of the first sub-picture and the second sub-picture. For example, the larger the number of sub-pictures included in each frame of static verification code picture, the larger the preset position interval may be, that is, the character to be displayed may float in a larger range.

Referring to fig. 4 and 5, taking the character to be displayed as "8" for example, two different position effects are given by randomly choosing the position of the first sub-picture within the position interval.

In addition, in fig. 4 and 5, the sub-picture occupied by "8" is the first sub-picture, and the remaining blank sub-pictures are the second sub-pictures.

Wherein, in the same frame,

the first display content is the same at different positions, the second display content is the same at different positions, and the first display content and the second display content are the same; or,

the first display content is different at different locations; or,

the second display content is different at different locations.

In the different frames, it is possible to have,

the first display contents are the same or different; and/or the presence of a gas in the gas,

the second display contents are the same or different.

For example, referring to fig. 6, in the same frame, taking the first display content as an example, the number "1" may be in some sub-pictures, and the letter "L" may be in other sub-pictures (for easier distinction, L is used to replace L in fig. 6); alternatively, the first display content is all gears, but the number of gears in different positions is different, for example, gears with three teeth in some positions, gears with four teeth in other positions, and the like.

In addition, the display content in different frames may be the same or different. Still taking the first display content as an example, the number "1" may be in one frame and the letter "L" (lower case L) may be in another frame.

In this embodiment, taking the example that the first display content and the second display content are both numbers "1", since the first display content and the second display content are the same in the same frame, the machine cannot recognize the verification code even if capturing a frame of picture.

S12': and playing the static verification code picture to obtain a dynamic verification code picture, wherein a first dynamic content is obtained according to the first display content during playing, a second dynamic content is obtained according to the second display content, and the first dynamic content and the second dynamic content have different dynamic information.

The static verification code picture can be played frame by frame to obtain the dynamic verification code picture.

Dynamic display content can be obtained by playing frame by frame, the first dynamic content and the second dynamic content have different dynamic information, and the verification code which can be identified by human eyes is obtained.

For example, referring to fig. 7, "1" in the first display content is rotated clockwise with the center point, and "1" in the second display content is rotated counterclockwise with the center point.

Because the rotation directions of the two are different, human eyes can distinguish the two, and the displayed character is '8'. However, the machine can only capture static content, that is, when the machine captures a static verification code, the machine sees all the content of "1" and cannot see that the displayed character is "8", thereby reducing the success rate of automatic recognition of the machine.

It is to be understood that the dynamic information is not limited to direction, but may be different in frequency and/or different in motion. For example, the first display content and the second display content are both rotated clockwise, but the frequency of rotation is different; and/or the first display content is panned and the second display content is rotated.

In addition, the static verification code picture further comprises a third sub-picture, the third sub-picture is a sub-picture where the interference point is located, the third sub-picture comprises third display content, third dynamic content is obtained according to the third display content when the third sub-picture is played frame by frame, and the third dynamic content and the first dynamic content have the same dynamic information.

Optionally, the third display content is the same or different in the same frame; or,

the third display content is the same or different in different frames; or,

the third display content is the same as or different from the first display content and/or the second display content in the same frame.

In the embodiment, the sub-picture where the verification code is located and the sub-picture where the background is located are distinguished, the sub-picture where the verification code is located and the sub-picture where the background is located have different motion information to realize the identification of the verification code by human eyes, in addition, the verification code is displayed only after the first display content in the sub-picture where the verification code is located and the second display content in the sub-picture where the background is located are played frame by frame, and the verification code cannot be identified when a single frame is used, so that the success rate of automatic identification of a machine can be reduced, the risk of cracking the verification code is reduced, and the network safety is improved. In addition, compared with the methods of blurring, warping, adding noise and the like generally used by static verification code pictures, the present embodiment may not perform the processing of blurring, warping, adding noise and the like, and may improve the user experience.
