Detailed Description

Features and exemplary embodiments of various aspects of the present application will be described in detail below, and in order to make objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are intended to be illustrative only and are not intended to be limiting. It will be apparent to one skilled in the art that the present application may be practiced without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present application by illustrating examples thereof.

Under the condition that a user accesses network resources, such as login, payment and the like, in order to prevent malicious behaviors of malicious users, such as batch registration, ticket swiping, abnormal continuous login and the like, a graphical verification code is set, so that the user can verify according to the verification code to distinguish normal users, machines and automatic programs.

For example, the verification code information is directly recorded on the graphic verification code, the user inputs the verification code information viewed in an input box displayed on the verification device, and the verification device verifies whether the verification code information input by the user is consistent with the verification code information on the graphic verification code. And if the verification result is consistent with the verification result, the verification is successful, namely the user performing the verification operation is determined to be a normal user.

For another example, the graphical verification code includes a plurality of pictures, the user selects a picture of a specified type on the verification device, and the verification device verifies whether the picture selected by the user is consistent with a picture of a pre-specified type. And if the verification result is consistent with the verification result, the verification is successful, namely the user performing the verification operation is determined to be a normal user.

For example, the graphical verification code is recorded with a randomly generated formula, the user inputs the calculation result of the formula on the verification device, and the verification device verifies whether the calculation result input by the user is consistent with the actual calculation result of the formula. And if the verification result is consistent with the verification result, the verification is successful, namely the user performing the verification operation is determined to be a normal user.

For another example, a slider is randomly generated in the graphical verification code, the user moves the slider to a specified position in the graphical verification code on the verification device, and whether the position where the slider is stopped after being moved is consistent with the specified position is verified. And if the verification result is consistent with the verification result, the verification is successful, namely the user performing the verification operation is determined to be a normal user.

However, the graphical verification code directly recording the verification information, the graphical verification code including the plurality of pictures, and the graphical verification code recording the formula, a malicious user can identify and calculate the verification of the graphical verification code directly recording the verification information, the graphical verification code including the plurality of pictures, and the graphical verification code recording the formula by using a picture identification technology, a character identification technology, and the like through a machine or an automatic program, so that malicious cracking is realized, the cracking difficulty is low, and the verification safety is reduced.

The moving precision requirement of the graphic verification code of the randomly generated sliding block is high, the operation of a normal user is easily judged to be a machine or an automatic program by mistake, the misjudgment rate is high, and the convenience of verification operation is reduced.

The embodiment of the application provides a method, a device, equipment and a storage medium for generating, displaying and verifying a graphic verification code, wherein the graphic verification code has a higher security protection level and can improve the security of verification. In addition, the requirement on the precision of the operation of the user in the verification process is low, the misjudgment rate can be reduced, and the convenience of the verification operation can be improved.

In the embodiment of the application, the execution end of the graph verification code generation, display and verification method may be an integrated structure or a distributed structure.

In some examples, the execution end of the graphical verification code generation, display and verification method is an integrated structure, i.e. the graphical verification code generation, display and verification method can be realized by one device.

In other examples, the execution end of the graphical verification code generation, display, and verification method may be a distributed structure, that is, a front end and a background distributed design for executing the graphical verification code generation, display, and verification method, where the front end may be implemented by one device, such as a user terminal; the background may be implemented by another device, such as a server. The background can realize the generation of the graphic verification code; the front end can realize the display of the graphic verification code; the front end and the background can jointly realize the verification of the graphic verification code.

The following will specifically describe the generation, display and verification of the graphic verification code, respectively.

The application provides a method for generating a graphic verification code in a first aspect. Fig. 1 is a flowchart of an embodiment of a method for generating a graphical verification code according to a first aspect of the present application. As shown in fig. 1, the method for generating a graphic verification code may include steps S101 to S104.

In step S101, a plurality of elements are randomly acquired from an element database.

The element database includes a plurality of elements for generating a graphical passcode. The total number of elements in the element database is greater than or equal to the number of randomly acquired elements. For example, the element database includes M elements, and N elements are randomly acquired from the element database in step S101, wherein M ≧ N.

The element database may include elements of different kinds. For example, the elements included in the element database may include, but are not limited to, one or more types of letters, numbers, Chinese characters, and pictures. The element database may include a plurality of element sub-databases, each element sub-database including a type of element. For example, the element sub-database may include an english alphabet sub-database, a numeric sub-database, or a chinese character in-code extension specification sub-database (i.e., GBK chinese character sub-database), etc.

In some examples, the elements in the element database may be selected to be easily distinguished by a user, so as to reduce a misjudgment rate in verification and improve convenience of user operation.

In some examples, the variety of elements in the element database may also be increased, increasing the variety of randomly acquired multiple elements. On one hand, the increasing of the types of the elements in the element database and the increasing of the types of the elements which are randomly obtained can increase the difficulty of machine identification, namely increase the difficulty of malicious cracking of verification, and improve the safety of the graphic verification code generated by the randomly selected elements; on the other hand, the variety of the elements in the element database is increased, the variety of the elements is increased by increasing the variety of the plurality of elements which are randomly acquired, and correspondingly, the variety of the verification rules in the verification process can also be increased.

In step S102, an area identifier of each partition in a preset background picture is obtained.

The background picture may be divided into a plurality of partitions. Specifically, the background picture may be equally divided into a plurality of partitions. For example, an X-Y coordinate system may be established for the background picture, and the background picture may be equally divided into a plurality of partitions according to the pixel coordinates in the X-axis direction. For another example, an X-Y coordinate system may be established for the background picture, and the background picture may be equally divided into a plurality of partitions according to the pixel coordinates in the Y-axis direction. The background picture may be a blank picture.

The number of partitions in the background picture may be determined according to the number of elements randomly acquired in step S101. In some examples, the number of background picture partitions is the same as the number of elements randomly fetched from the element database. Each partition is correspondingly provided with an area identifier. The region identifier is used to identify the partition. The area identifier can be distributed to each partition after partitioning, and the area identifier of each partition can also be obtained by utilizing the self attribute of the background picture.

In some examples, the region identification may include a region number or pixel coordinates. For example, the region identifier includes a region number, and the rule of the region number is not limited herein. For another example, the area identifier includes pixel coordinates, the partition includes a plurality of pixels, correspondingly, the partition has a plurality of pixel coordinates, and the pixel coordinates of any one or more pixels located in the partition can be used as the area identifier of the partition.

In step S103, a random correspondence relationship between the plurality of elements and the area identification is randomly generated.

The correspondence between the elements and the region identifications is randomly generated. The corresponding relationship between the elements and the area identifiers needs to be generated at random every time the graphic verification code is generated.

In step S104, a graphic verification code is generated based on the distribution, elements, and area identifiers of the respective partitions in the background picture.

The graphical verification code includes a first graphical verification component and a second graphical verification component. The first graphic verification component includes respective graphic codes. The number of graphic codes in the first graphic verification component is not limited herein.

The graphic code comprises a background picture and elements which are positioned in each partition of the background picture and have random corresponding relation with the area identification of the partition. Specifically, an element having a random correspondence with each partition may be generated on each partition according to the random correspondence between each element and each partition. The background picture with the elements having random corresponding relations with the partitions is the graphic code.

The second graphical verification component is derived from the verification element. The verification element includes a partial element of the elements of the graphic code. The second graphical verification component may be used to define the verification element. The verification element is used for matching with the element selected by the user input in the verification process to determine whether the verification is successful. The second graphical verification component may be randomly generated. The verification elements defined by the second graphic verification component are randomly selected partial elements in the graphic code, and the sequence of the verification elements defined by the second graphic verification component is also random.

In some examples, the second graphical verification component score includes a verification element. For example, the elements in the graphical code may include the numbers 1 to 9, and the second image verification component may include the numbers 1, 2 and 3. The second graphical verification component in the graphical verification code generated at different times may include verification elements that are different and irregular.

In other examples, the second verification component includes hint information that defines the verification element. For example, elements in the graphical code include the numbers 1 to 9, the second image verification component may include a prompt message "select a number less than 4", the prompt message defining verification elements including the numbers 1, 2 and 3. The prompt information included by the second graphic verification component in the graphic verification codes generated at different times can be different and has no rule.

In some examples, the number of graphical codes in the graphical verification code is the same as the number of elements defined by the second graphical verification component. Each of the graphical verification codes corresponds to an element defined by the second graphical verification component.

For example, fig. 2 is a schematic diagram of an example of a structure of a graphical verification code provided in an embodiment of the present application. As shown in FIG. 2, the graphical authentication code 20 includes a first graphical authentication component 21 and a second graphical authentication component 22. The first graphic verification component 21 includes three graphic codes 211, each graphic code 211 includes eight partitions, and the area identifications of the eight partitions are a1 to a8 from top to bottom in fig. 2. The elements of each graphic code 211 include 3, 5, 9, a, b, c, good and bad. In the graph verification code shown in fig. 2, the random correspondence between the elements in the three graph codes 211 and the area identifiers is the same, and the random correspondence is specifically shown in the following table one:

watch 1

As shown in FIG. 2, the second graphical verification component 22 includes the verification elements "good", "3", "c".

In some examples, the randomly generated correspondence of the element in the first graphical code to the area identification of each partition in the background picture is different from the randomly generated correspondence of the element in the second graphical code to the area identification of each partition in the background picture. I.e. the distribution of the elements in the first graphical code over the background picture is different from the distribution of the elements in the second graphical code over the background picture. The first graphic code is one graphic code in the first graphic verification component, and the second graphic code is the other graphic code in the first graphic verification component. That is, the randomly generated correspondence of the element and the region identifier in different graphic codes in the first graphic verification component may be different. In different graphic codes, the corresponding relation between the elements and the area identification is different, so that the difficulty of cracking the graphic verification code can be further improved, and the safety and the accuracy of verification by using the graphic verification code are improved.

For example, fig. 3 is a schematic diagram of another example of the structure of a graphical verification code provided in the embodiment of the present application. As shown in FIG. 3, the graphical authentication code 20 includes a first graphical authentication component 21 and a second graphical authentication component 22. The first graphic verification component 21 includes three graphic codes 211, each graphic code 211 includes eight partitions, and in fig. 3, the area identifications of the eight partitions of each graphic code 211 are a1 to a8 from top to bottom, respectively. The elements of each graphic code 211 include 3, 5, 9, a, b, c, good and bad. In the graphical verification code shown in fig. 3, the random correspondence between the elements in the three graphical codes 211 and the area identifiers is different, and the random correspondence is specifically shown in the following table two:

watch two

As shown in FIG. 3, the second graphical verification component 22 includes the verification elements "good", "3", "c".

In the embodiment of the application, the elements for generating the graphic verification code are randomly acquired from an element database. The corresponding relation between the area identification of each partition in the background picture and the randomly acquired elements is also randomly generated. And generating a graph verification code comprising a first graph verification component and a second graph verification component according to the distribution of each partition in the background picture, the randomly acquired elements and the area identification. Even if the machine or the automatic program identifies the verification elements defined by the second graphic verification component, due to the double random action of the element acquisition and the corresponding relationship generation, the machine or the automatic program is difficult to crack the corresponding relationship between the elements and the area identifiers in the graphic verification code, namely the corresponding relationship between the elements and the partitions in the graphic verification code, so that the cracking difficulty is improved, the risk of malicious cracking of the graphic verification code is reduced, and the safety and the accuracy of verification performed by using the generated graphic verification code can be improved.

In case of a failure of the verification or an active initiation of a refresh request, the graphical passcode may be refreshed, i.e. a new graphical passcode is generated. Fig. 4 is a flowchart of another embodiment of a method for generating a graphical verification code according to the first aspect of the present application. Fig. 4 is different from fig. 1 in that the method for generating a graphic verification code shown in fig. 4 may further include step S105.

In step S105, a refresh command is received, and in response to the refresh command, the process may jump to step S101 and continue to execute steps S101 to S104.

Responding to a refresh command, randomly acquiring a plurality of elements from the element database again, randomly generating the corresponding relation between the acquired elements and the area identification again, and generating a new graphic verification code according to the distribution of each partition in the background picture, the randomly acquired elements and the area identification again. The new graphical passcode generated after refresh may be different from the graphical passcode before refresh. In particular, the first and second graphical verification components of the new graphical verification code generated after refresh may be different from the first and second graphical verification components of the graphical verification code prior to refresh.

The refresh command may be a command generated according to a refresh request input by a user, or may be a command generated when the verification of the graphic verification code fails, which is not limited herein.

By refreshing, the graph verification code can be updated in time, the cracking difficulty of the graph verification code is further improved, and the safety and the accuracy of verification by using the graph verification code are improved.

In some examples, an interference pattern may also be added to the first graphical verification component and/or the second graphical verification component to reduce the likelihood that the content of the first graphical verification component and/or the content of the second graphical verification component is recognized by a machine or automated program. The interference pattern may be, but is not limited to, noise, interference lines, and the like.

In other examples, display attributes of elements in the first graphical verification component and/or the second graphical verification component may also be changed to reduce the likelihood that the content of the first graphical verification component and/or the content of the second graphical verification component is recognized by a machine or automated program. For example, changing fonts, changing colors, etc., without limitation.

After the graphical verification code is generated, the graphical verification code can be displayed so that a user can verify through the graphical verification code. In some examples, the verification interface may be displayed by the front end of the execution end. The verification interface may include a select area and a second graphical verification component, the select area including one element of each graphical code in the graphical verification code, i.e., the select area including one element of each graphical code in the graphical verification code. The display of the graphical verification code will be explained below.

A second aspect of the present application provides a graphical passcode display method. Fig. 5 is a flowchart of an embodiment of a method for displaying a verification code according to a second aspect of the present application. As shown in fig. 5, the pattern verification code form method may include step S301 and step S302.

In step S301, a trigger input is received.

The trigger input may be a trigger input of the application program start received by the front end of the execution end, or may also be a trigger input of the control jumping to the verification interface, which is not limited herein.

In step S302, in response to a trigger input, a verification interface is displayed.

The verification interface includes a selected area and a second graphical verification component in the graphical verification code. The selected area includes one element of each graphic code in the graphic verification code. Elements located in the selected area are considered selected elements. The elements in the selected area may be arranged laterally, longitudinally, or in other ways, and are not limited herein.

The pattern verification code comprises a first pattern verification component and a second pattern verification component, and the first pattern verification component comprises each pattern code. The graphic code comprises a background picture and randomly acquired elements which are positioned in each partition of the background picture and have a randomly generated corresponding relationship with the area identification of the partition. The second graphic verification component is obtained according to verification elements, and the verification elements comprise partial elements in the elements of the graphic code. In some examples, elements may include, but are not limited to, one or more types that may include, but are not limited to, letters, numbers, Chinese characters, pictures. For the details of the graphic verification code, reference may be made to the related description in the above embodiments, which is not repeated herein.

In some examples, the area identifier may include, but is not limited to, an area number or a pixel coordinate, and specific contents may refer to relevant descriptions in the above embodiments, which are not described herein again.

In some examples, the second graphical verification component includes the verification element. In other examples, the second graphical verification component includes a prompt message. The hint information is used to define the verification element. For details of the second pattern verification component, reference may be made to the related description in the above embodiments, and details are not repeated here.

In some examples, the distribution of elements in multiple graphical codes in the graphical captcha may be the same. In other examples, the distribution of the elements in the first graphical code in the partitions is different from the distribution of the elements in the second graphical code in the partitions. The first graphic code is one of the first graphic verification components. The second graphic code is another graphic code in the first graphic verification component. The elements in different graphic codes in the same graphic verification code are distributed differently in each partition, so that the cracking difficulty of the graphic verification code can be further improved, and the safety and the accuracy of verification by using the graphic verification code are improved. For the specific content of the same or different distribution of the elements in the graphic code in each partition, reference may be made to the related description that the corresponding relationship between the elements in the graphic code and the area identifiers of each partition may be the same or different in the above embodiments, and details are not repeated herein.

In some examples, the number of the graphic codes in the graphic verification code is the same as the number of the elements defined by the second graphic verification component, and specific contents may refer to the related description in the above embodiments, which is not repeated herein.

In some examples, the first graphical verification component and/or the second graphical verification component have an interference pattern. The interference pattern may include noise, interference lines, etc., and is not limited herein. The elements and other information in the first graphical verification component and/or the second graphical verification component may also be processed for font, color, etc. to reduce the likelihood that the content of the first graphical verification component and/or the content of the second graphical verification component will be recognized by a machine or automated program.

In some embodiments, each of the graphical passcodes may be presented in a roller form in the verification interface. The elements in the selected area can be replaced according to the selection of the user, so that the elements can be selected. I.e. each section of the graphic code scrolls through the selected area.

In some examples, only elements located in the selected area may be displayed in the verification interface. The reduction of the number of the displayed elements can avoid a machine or an automatic program from identifying all elements in the graphic code, and the difficulty of cracking the graphic verification code is improved, so that the safety and the accuracy of verification by using the graphic verification code are improved.

For example, fig. 6 is a schematic diagram of an example of a verification interface provided in the embodiment of the present application. As shown in FIG. 6, the graphical passcode includes three graphical codes, assuming the graphical passcode is as shown in FIG. 3. The second graphic verification component 22 includes verification elements "good", "3", "c". The verification interface includes a select area 41 and the verification interface displays only the elements of the graphical code located in the select area 41. The elements of the graphic code located in the selected area 41 are "good", "5", "9", respectively.

In other examples, the verification interface may also include a target area. The target area includes the selected area and at least some of the elements in each graphic code other than the elements in the selected area. The elements adjacent to the elements in the selected area in each graphic code can be displayed, so that the user can visually see the elements adjacent to the elements in the selected area, and the user can select how to perform the selection input according to the adjacent elements, thereby improving the convenience of the operation of the user.

For example, fig. 7 is a schematic diagram of another example of a verification interface provided in an embodiment of the present application. As shown in FIG. 7, the graphical passcode includes three graphical codes, assuming the graphical passcode is as shown in FIG. 3. The second graphic verification component 22 includes verification elements "good", "3", "c". The verification interface includes a target area 42. The target area 42 includes the selected area 41. The elements of the graphic code located in the selected area are "good", "5", "9", respectively. The target area 42 also includes two elements each located before and after "good" in the first graphic code, two elements each located before and after "5" in the second graphic code, and two elements each located before and after "9" in the third graphic code.

In an embodiment of the application, a verification interface is displayed in response to a received trigger input. The verification interface includes a selected area and a second graphical verification component in the graphical verification code. The selected area includes one element of each graphic code in the graphic verification code. The graphic code comprises a background picture and randomly acquired elements which are positioned in each partition of the background picture and have a randomly generated corresponding relationship with the area identification of the partition. Due to the dual random effect of the element acquisition and the corresponding relation, even if a machine or an automatic program identifies the verification elements limited by the second graph verification component, the machine or the automatic program is difficult to crack the corresponding relation between the elements and the area identification in the graph verification code, namely, the corresponding relation between the elements and the partitions in the graph verification code, so that the cracking difficulty is improved, the risk of malicious cracking of the graph verification code is reduced, and the safety of verification performed by using the generated graph verification code can be improved.

In the event that the user makes a selected input to the verification interface, the content in the verification interface may change. Fig. 8 is a flowchart of another embodiment of a method for displaying a graphical verification code according to the second aspect of the present application. Fig. 8 is different from fig. 5 in that the graphic verification code display method shown in fig. 8 may further include step S303 and step S304.

In step S303, a selection input is received.

The user may replace an element of the graphical code located in the selected area by a selection input. The graphic code can be displayed in a rolling wheel mode. For example, the execution end may control the section of the graphic code to scroll based on the received selection input, thereby replacing the element in the selected section.

In response to the selection input, the element of the graphic code located in the selected area is replaced by the first element to the second element in step S304.

In some examples, the selected input comprises a swipe input. For example, the execution end may be provided with a scroll wheel structure, such as a mouse with a scroll wheel, and the user may implement a slide input by sliding the scroll wheel of the mouse, and the execution end may implement the replacement of the element in the selected area in response to the slide input. For another example, the execution end may have a touch function, and the user may implement a sliding input through a sliding operation on the execution end, and the execution end responds to the sliding input to implement replacement of the element in the selected area.

The second element is another element except the first element in the graphic code. The partition of the second element in the background picture is the front N partition or the back N partition of the first element in the background picture, and N is a positive integer. For example, as shown in fig. 7, the execution end controls the third column of graphic codes to slide upwards in response to the slide input, so that the element in the selected area 41 is changed from the first element "9" to the second element "c". The second element "c" is located in a subsequent partition to the partition in which the first element "9" is located.

In the embodiment of the application, the selection of the elements in the graphical verification code by the user is realized through sliding input, and compared with the traditional mode of inputting the elements by an input box, the convenience of user operation is improved, and the interaction experience of the user operation is optimized.

In case of a failure of the verification or an active initiation of a refresh request, the graphical passcode may be refreshed, i.e. the generated new graphical passcode is displayed. Fig. 9 is a flowchart of a graphical verification code display method according to a second aspect of the present application. Fig. 9 is different from fig. 5 in that the graphic verification code display method shown in fig. 9 may further include step S305 and step S306.

In step S305, a refresh input is received.

The refresh input corresponds to the refresh command in the above embodiments, and is not described herein again.

In step S306, elements in the second graphical verification component and the target area in the verification interface are updated in response to the refresh input.

The new graphical verification code generated after the refresh may be different from the graphical verification code before the refresh, and thus, the elements in the second graphical verification component and the target area in the verification interface after the refresh are different from the elements in the second graphical verification component and the target area in the verification interface before the refresh.

By refreshing, the graphic verification code can be updated in time, the displayed verification interface can be updated, the cracking difficulty of the graphic verification code is further improved, and the safety and the accuracy of verification by using the graphic verification code are improved.

The third aspect of the application provides a verification method for a graphic verification code. Fig. 10 is a flowchart of an embodiment of a verification method for a verification code of a graphic provided in the third aspect of the present application. As shown in fig. 10, the verification method of the graphic verification code may include steps S501 to S503.

In step S501, a selected input for each of the graphic verification codes is received.

The graphical verification code includes a first graphical verification component and a second graphical verification component. The first graphic verification component includes respective graphic codes. The graphic code comprises a background picture and randomly acquired elements which are positioned in each partition of the background picture and have a randomly generated corresponding relationship with the area identification of the partition. The second graphical verification component is derived from the verification element. The verification element includes a partial element of the elements of the graphic code. In some examples, elements may include, but are not limited to, one or more types that may include, but are not limited to, letters, numbers, Chinese characters, pictures. For the details of the graphic verification code, reference may be made to the related description in the above embodiments, which is not repeated herein.

In some examples, the randomly generated correspondence of the elements in each graphic code to the area identifications of each partition in the background picture may be the same. In other examples, the randomly generated correspondence of the element in the first graphical code to the area identifier of each partition in the background picture is different from the randomly generated correspondence of the element in the second graphical code to the area identifier of each partition in the background picture. The first graphic code is one of the first graphic verification components. The second graphic code is another graphic code in the first graphic verification component. The specific content that the randomly generated correspondence between the elements in different graphic codes and the area identifiers of each partition in the background picture may be the same or different may refer to the relevant description in the above embodiments, and is not described herein again.

In some examples, the second graphical verification component includes a verification element. In other examples, the second graphical verification component includes a prompt message. The hint information is used to define the verification element. For details of the second pattern verification component, reference may be made to the related description in the above embodiments, and details are not repeated here.

In some examples, the first pattern verification component and/or the second pattern verification component have an interference pattern, and specific contents may refer to relevant descriptions in the above embodiments, and are not described herein again.

In step S502, in response to the selection input, a target element is selected in each graphic code.

The graphic code comprises a plurality of elements, and the target element can be selected in the graphic code through the selection input. The target element is the element selected for verification. Specifically, there is one target element in each graphic code. For the details of the selected input, reference may be made to the related description of the above embodiments, and further description is omitted here.

In step S503, in the case where the target element matches the verification element defined by the second graphic verification component, it is determined that the verification is successful.

In some examples, the second graphical verification component includes a verification element. The graphic codes in the first graphic verification component have an arrangement order. The second graphical verification component also includes verification elements having an order of arrangement. And under the condition that the target elements are completely the same as the verification elements according to the arrangement sequence of the graphic codes in the graphic verification code, namely the target elements are matched with the verification elements defined by the second graphic verification component, and the verification success is determined.

In the event that the target element does not match the verification element defined by the second graphical verification component, determining that verification failed. Specifically, in the case that the target element is not exactly the same as the verification element in the order of arrangement of the graphic codes in the graphic verification code, that is, the target element does not match the verification element defined by the second graphic verification component, it is determined that the verification has failed.

For example, the graphical passcode includes three graphical codes. The verification elements defined by the second graphical verification component include, in order, "good", "3", and "c". In the case where the selected target elements in the graphical passcode include "good", "3", and "c" in the order of arrangement, the verification is determined to be successful. In the event that the selected target elements in the graphical verification code do not include all of the verification elements defined by the second graphical verification component, a verification failure is determined, e.g., the target elements include "a", "3", and "c" in the order of arrangement. The selected target elements in the graphical verification code include all verification elements defined by the second graphical verification component, but the target elements are arranged in a different order than the verification elements defined by the second graphical verification component, and a verification failure is determined, e.g., the target elements include "3", "good" and "c" in the order of arrangement.

In other examples, the second graphical verification component includes a prompt message. In case the verification elements defined by the hint information comprise all target elements, i.e. the target elements match the verification elements defined by the second graphical verification component, a verification success is determined.

In case the verification elements defined by the hint information do not include all target elements, i.e. the target elements do not match the verification elements defined by the second graphical verification component, a verification failure is determined.

For example, the elements in the graphic code are as shown in table one, and the hint information is "please select the number therein", i.e., the hint information defines verification elements including "3", "5", and "9". In the case where the target elements include "3", "5", and "9", the verification element defined by the hint information includes all the target elements, and the order of the target elements may not be defined herein, and it is determined that the verification is successful. In the case where the target elements include "c", "3", and "b", the verification elements defined by the hint information do not include all of the target elements, and it is determined that the verification has failed.

In an embodiment of the application, the target element is selected in each graphical code in response to a received selection input for each graphical code in the graphical captcha. In the event that the target element matches a verification element defined by the second graphical verification component, a verification success is determined. Due to the double random action of element acquisition and corresponding relation generation, even if a machine or an automatic program identifies verification elements limited by a second graph verification component, the corresponding relation between the elements and the area identification in the graph verification code is difficult to crack, namely the corresponding relation between the elements and the partitions in the graph verification code is difficult to crack, the cracking difficulty is improved, the risk that the graph verification code is maliciously cracked is reduced, and the safety and the accuracy of verification performed by using the graph verification code can be improved.

Fig. 11 is a flowchart of another embodiment of a verification method for a verification code of a graphic provided in the third aspect of the present application. Fig. 11 differs from fig. 10 in that the selected input may include a slide input, and step S502 in fig. 10 may be specifically detailed as step S5021 and step S5022 in fig. 11.

The partition of the second element in the background picture is the front N partition or the back N partition of the first element in the background picture, and N is a positive integer. By responding to the sliding input, the elements in the front N subarea or the back N subarea which are divided into subareas in the background picture where the first element is located can be used as target elements, so that the target elements are changed in a rolling manner, the convenience of user operation is improved, and the user experience of man-machine interaction is optimized.

In step S5022, a second element is taken as a target element.

The selected input is operable to select a partition in the graphical code having an element. For example, the user selected element "a," which for the executive, selected the partition of element "a" on the background picture.

In step S5024, the element corresponding to the area id of the selected partition is used as the target element according to the correspondence between the element and the area id.

In the process of generating the graphic verification code, the corresponding relation between the elements and the area identification is randomly generated. The element corresponding to the region identifier of the selected partition may be taken as the target element using the previously stored correspondence of the randomly generated element to the region identifier. Because the target elements are determined according to the area identifications of the partitions, and the corresponding relations between the randomly generated elements and the area identifications are different in the process of generating the graphic verification code every time, a machine or an automatic program is difficult to crack the corresponding relations between the elements and the area identifications in the graphic verification code, namely the corresponding relations between the elements and the partitions in the graphic verification code, the cracking difficulty is improved, the risk that the graphic verification code is maliciously cracked is reduced, and the safety and the accuracy of verification performed by using the generated graphic verification code can be improved.
