The verification code data is binary verification code data generated by firstly generating a verification code picture according to a verification code request and then processing the verification code picture.

The verification code picture comprises a verification track, the verification track is provided with a starting point, an ending point and a plurality of folding points between the starting point and the ending point, the folding points are used for determining the trend or the path of the verification track, the number of the folding points can be modified and set according to actual requirements, and for example, the folding points can comprise 2, 3, 4 or more. Each break point has a break point sequence and an associated color, specifically, for example, the number of break points is set to 3, for example, the first break point is a1, the second break point is a2, the third break point is a3, and the path of the verification track can be determined according to the break point sequence and the start point and the end point of the verification track, that is, the sequence of the verification track is the start point, the first break point a1, the second break point a2, the third break point a3, and the end point. When the verification is performed, the verification must be performed according to the verification track so as to pass the verification. Each break point has an associated color for generating a verification prompt according to which the target user can verify. Because the break points have associated colors, a target user can effectively identify the colors, and in the process of cracking the verification code in the prior art, the aim of realizing automatic positioning to realize verification is fulfilled after data processing such as grabbing, binarization, gray scale, filtering, interference removal and the like are mainly performed on the generated verification code picture. The method and the device set the associated color for each break point, and can not distinguish the associated color of the break point after adopting data processing such as binarization, gray scale, filtering, interference elimination and the like, so that the verification code picture of the method and the device is prevented from being broken.

By generating the binary verification code data, even if the binary verification code data are intercepted in the verification code data transmission process, the content of the verification code picture cannot be clearly known, so that the cracking difficulty is improved, and the security of the verification code data is improved.

In operation S230, a display picture and a verification hint are generated by the client according to the received verification code data, the verification hint being generated according to the break ordering and associated colors of each break.

In some exemplary embodiments of the present disclosure, the client receives the verification code data to generate a display picture, which may display, for example, a position of a start point, a position of an end point, a position of each break point, and an associated color corresponding to each break point of the verification track.

The verification prompt is generated according to the break point ordering and the associated color. For example, if the first folding point is a1, the second folding point is a2, and the associated colors corresponding to the third folding point is a3 are blue, yellow, and red, respectively, the generated indication information may be "sequentially passing the slider through blue, yellow, and red from the start point, and reaching the end point". The target user can complete verification operation according to the content displayed on the display picture and the verification prompt.

In operation S240, sampling data associated with the unique identification is generated by the client in response to the content input by the target user according to the display picture and the authentication prompt.

In some exemplary embodiments of the present disclosure, during an input of a verification operation by a target user according to a verification prompt, the content of the input of the target user is recorded, and sampling data for verifying whether the target user having a unique identification passes or not is generated.

In operation S250, the verification duration and the verification speed in the range corresponding to each break point are determined by the cache database according to the received sampling data, and a verification result is generated.

In some embodiments of the present disclosure, by determining the verification duration in the range corresponding to each setpoint, the order of the target user sequentially passing through the break points in the verification process may be determined, so as to determine whether the verification track is correct, and by determining the verification speed in the range corresponding to each break point, whether the verification is manual verification or machine verification is determined, so as to prevent the problem that the machine verification leads to the failure of the function of the verification code.

In operation S260, the verification result is received and presented through the client.

The following describes details of the verification code data processing method according to the embodiment of the present disclosure with reference to fig. 3 to 10.

Fig. 3 schematically illustrates a flowchart of a captcha data processing method in operation S220 according to an embodiment of the present disclosure.

As shown in fig. 3, operation S220 includes operations S221 to S222.

In operation S221, a verification code picture is generated from the randomly acquired background picture by the target server in response to the verification code request.

The background picture is, for example, a picture stored in a preset picture database, the size and resolution of the background picture are inconsistent, and by randomly acquiring the background picture, the parameters such as the size and the verification track of the verification code picture are generated to have randomness, so that the verification code picture can be effectively prevented from being broken, and the safety is improved.

In operation S222, the verification code picture is binary processed to generate binary verification code data.

The target server needs to send the verification code picture to the client for display after generating the verification code picture, and if the verification code picture is sent, the verification code picture is easy to intercept and machine processing is performed on intercepted content so as to achieve the purpose of cracking. Binary processing is carried out on the verification code picture to generate binary verification code data, so that the verification code picture cannot be effectively acquired, the safety of data transmission from the target server to the client is improved, and the cracking difficulty is further improved.

In some optional embodiments, encryption processing can be performed on binary verification code data, and after receiving the binary verification code data, the client performs decryption processing, so that the security of data transmission can be further improved.

Fig. 4A schematically illustrates a flowchart of a captcha data processing method according to an embodiment of the present disclosure at operation S221. Fig. 4B schematically illustrates a schematic diagram of a captcha data processing method according to an embodiment of the present disclosure in operation S221.

As shown in fig. 4A, operation S221 includes operations S2211 to S2215.

In operation S2211, a background picture is randomly acquired from a preset picture database through a target server in response to a request for a verification code.

The preset picture database can be, for example, an internet picture database, and background pictures are obtained from the internet picture database in real time, so that the updating of data can be ensured, and the risk of cracking by a cracking person aiming at a specific database can be avoided.

In operation S2212, the start point and the end point of the verification track are randomly generated according to the size of the background picture.

Illustratively, when the sizes of the background pictures are different, the distances between the start point and the end point are also different, and after the sizes of the background pictures are acquired, the position coordinates (x 0, y 0) of the start point and the position coordinates (x 4, y 4) of the end point of the verification track are randomly generated according to the two-dimensional abscissa of the background pictures.

In operation S2213, a plurality of folding points are randomly generated according to the start point and the end point.

For example, the number of generated break points may be determined according to the size of the background picture, more break points may be generated when the size of the background picture is larger, and fewer break points may be generated when the size of the background picture is smaller. For example, the number of generated break points is determined to be 3. Coordinates of 3 folding points are generated between the coordinate positions (x 0, y 0) corresponding to the starting point and the coordinate positions (x 4, y 4) corresponding to the ending point respectively, namely, the first folding point a1 is (x 1, y 1), the second folding point a2 is (x 2, y 2), and the third folding point a3 is (x 3, y 3). Each break point has an associated color that,

in operation S2214, an associated color of each break point is determined according to the break point ranking of each break point.

For example, the first folding point is a1, the second folding point is a2, and the third folding point is a3, and the associated colors corresponding to the first folding point are blue B, yellow Y, and red R, respectively. By determining the associated color of each set point, verification prompts are conveniently generated, and a target user can perform correct verification operation according to the verification prompts.

In operation S2215, a verification code picture is generated according to the background picture, the start point, the end point, the plurality of break points, and the associated color of each break point.

Illustratively, a verification track with a starting point, an ending point, a plurality of break points and associated colors of each break point on the verification code picture is generated, and a broken line as shown in fig. 4B is not shown in the verification code picture, wherein the verification track can be obtained by a target user according to the input of a verification prompt operation slider.

Fig. 5 schematically illustrates a flowchart of a captcha data processing method in operation S230 according to an embodiment of the present disclosure.

As shown in fig. 5, operation S230 includes operations S231 to S232.

In operation S231, decoding the received verification code data by the client generates a display picture, the display picture including a start point, an end point, and a plurality of break points of the verification track, each break point displaying an associated color.

The client decodes the received verification code data to obtain a display picture, the display picture is displayed to the user at the client, and the content displayed by the display picture can be consistent with the content of the verification code picture generated by the target server. In addition, when the client generates the display picture, the slider is displayed at the starting point position of the verification track, the slider can be overlapped with the starting point position, for example, and the target user can slide aiming at the slider so as to draw the moving track of the slider.

In operation S232, a verification hint is generated according to the verification track, the break ordering for each break, and the associated color for each break.

Illustratively, the sorting of the folding points is sequentially a first folding point a1, a second folding point a2 and a third folding point a3, the associated color of the first folding point a1 is blue B, the associated color of the second folding point a2 is yellow Y, and the associated color of the third folding point a3 is red R, so that the generated verification prompt may be "please swipe through the three folding points of blue, yellow and red in turn and finally reach the end point", and the verification prompt may be displayed on the peripheral side, such as the lower side, of the display picture.

Fig. 6 schematically illustrates a flowchart of a captcha data processing method in operation S250 according to an embodiment of the present disclosure.

As shown in fig. 6, operation S250 includes operations S251 to S254.

In operation S251, sampling data is received through a cache database.

In operation S252, a verification duration in a range corresponding to each break point is determined, and a first verification result is generated.

In operation S253, a verification speed in a range corresponding to each folding point is determined, and a second verification result is generated.

In operation S254, a verification result is generated according to the first verification result and the second verification result.

Fig. 7A schematically illustrates a flowchart of a captcha data processing method in operation S252, according to an embodiment of the present disclosure. Fig. 7B schematically shows a flowchart of a captcha data processing method in operation S253 according to an embodiment of the present disclosure.

As described in detail below in conjunction with fig. 7A and 7B, as shown in fig. 7A, operation S252 includes operations S2521 to S2524.

In operation S2521, a sampling distance between the sampling point and the break point is determined according to coordinate data corresponding to the sampling point in the sampling data.

In the process that the target user operates the sliding block to move according to the verification prompt, the moving data of the sliding block can be sampled according to the set sampling speed. For example, the position information of the slider is acquired every 5 ms.

The coordinate data corresponding to each sampling point is (x) _n ，y _n ) Calculating the sampling distance between the sampling point and the folding point: m= (x _n -x ₁ ) ² +(y _n -y ₁ ) ² 。

In operation S2522, a sampling point having the smallest sampling distance from the break point is determined as a target sampling point within the range corresponding to the break point.

In this embodiment, since the sampling interval is fixed, the sampling point does not completely coincide with the break point during the sampling process, and the sampling point with the smallest sampling distance from the break point is determined as the target sampling point, at this time, it can be approximately considered that the slider passes through the position corresponding to the break point when the target sampling point.

In operation S2523, a length of time from the start point to the target sampling point is determined as a verification length of time within the range corresponding to the break point.

Illustratively, for example, the start point time is 0, and the time from the start point position to the target sampling point corresponding to the break point is t. For example, the number of the folding points is 3, the verification duration corresponding to the first folding point a1 is t1, the verification duration corresponding to the second folding point a2 is t2, and the verification duration corresponding to the third folding point a3 is t3, namely, the time required for the sliding block to slide from the starting point to each folding point.

In operation S2524, a first verification result is generated according to the relationship between the verification duration and the break ordering in the range corresponding to each break.

For example, the first, second and third folding points a1, a2 and a3 are respectively ranked as 1 < 2 < 3, and the verification time period t1 < t2 < t3 corresponding to the first, second and third folding points a1, a2 and a3. That is, the slider passes through the first folding point a1, the second folding point a2 and the third folding point a3 in sequence when sliding.

In some alternative embodiments of the present disclosure, the verification time process may present a problem, as the time or speed of different personnel manipulation varies as the target user manipulates the slider movement according to the verification prompts. For the verification duration of the last folding point, a limit value can be set, and when the verification duration of the last folding point exceeds the threshold value, a first verification result which is not passed by verification can be directly returned, so that the safety in the verification process is ensured.

If the verification duration in the corresponding range of each break point is consistent with the relation of the break point ordering, generating a first verification result as verification passing.

If the verification duration in the corresponding range of each break point is inconsistent with the relation of the break point ordering, generating a first verification result as that verification is not passed.

After the first verification result is passed, operation S253 is performed. Otherwise, returning the result of verification failure.

As shown in fig. 7B, operation S253 includes operations S2531 to S2533.

In operation S2531, a verification speed of a target sampling point within a range corresponding to the break point is determined from the received sampling data.

For example, after the target sampling point is determined, the speed of the slider sliding to the target sampling point is determined as a verification speed, which can identify the speed of the slider sliding to the vicinity of the break point. In an alternative embodiment, the average speed of three sampling points including the target sampling point and the sampling points on two adjacent sides can be determined, and the speed of the sliding block in the vicinity of the folding point can be reflected more accurately.

In operation S2532, an average speed of the verification track of the previous period of the break point is determined.

For example, the average speed of the verification track of the previous period of the folding point may refer to the average speed of the starting point to the first folding point, the average speed of the first folding point to the second folding point, the average speed … … of the second folding point to the third folding point, and the average speed of the folding point adjacent to the ending point.

In operation S2533, a second verification result is generated according to the relationship between the verification speed and the average speed of each break point.

In some embodiments of the present disclosure, since the location of the break point is the location at which the verification track turns, the speed of the slider at the break point is less than the average speed of the verification track for the break point migration period during the process of performing the manual verification. By comparing the average speed of each section in the verification track with the verification speed of the folding point, accurate verification is realized, and a cracking person is effectively prevented from cracking in a sliding mode of the sliding block.

In some embodiments of the present disclosure, when the first validation result is pass and the second validation result is also pass, then a validation result is generated from the first validation result and the second validation result, the validation result being pass. When at least one of the first verification result and the second verification result is failed, the verification result is failed.

In some alternative embodiments, when the first verification result is failed, the step of operation S253 described above may not be performed, and the verification result may be directly generated as failed, thereby improving efficiency.

Fig. 8 schematically illustrates a flowchart of storing captcha data and sample data, which is further included in a captcha data processing method according to an embodiment of the present disclosure.

As shown in fig. 8, the flow 300 includes operations S3 to S320.

In operation S310, after binary verification code data is generated from the randomly acquired background picture, the cache database receives and stores the unique identification and verification code data transmitted by the target server.

In operation S320, after the client generates sample data associated with the unique identifier in response to the content input by the target user according to the display picture and the authentication prompt, the cache database receives and stores the sample data associated with the unique identifier.

In the embodiment of the present disclosure, by performing operation S310 and operation S320, the unique identifier, the verification code data and the sampling data are sent to the cache database, so that after verification is passed, whether the service data submitted by the client is normal or not is determined by querying whether the related data exist or not. For example, when the client intercepts the verification result returned by the target server and submits a false verification result, the target server cannot perform effective judgment, and the authenticity of the verification result can be effectively judged by querying the data cached by the cached data.

Fig. 9 schematically illustrates a flowchart of operation S270 further included in the captcha data processing method according to an embodiment of the present disclosure.

As shown in fig. 9, the verification code data processing method further includes an operation 270: and deleting the verification code data and the sampling data corresponding to the unique identifier through caching the instruction of which the database responds to the verification result as failed.

In the embodiment of the disclosure, when the verification result is failed, the sampling data stored in the cache database is deleted, so that the client is prevented from realizing the purpose of cracking by submitting false verification results when the verification result is failed. In the embodiment of the disclosure, when the target server receives the instruction that the verification result submitted by the client is passed, the verification code data and the sampling data in the cache database are queried according to the unique identifier, so that the accuracy of the verification result is ensured, and if the verification result is forged, the verification result can be timely stopped, and the safety is improved.

Fig. 10 schematically illustrates a flowchart of querying verification code data and sample data, which is further included in the verification code data processing method according to an embodiment of the present disclosure.

As shown in fig. 10, the flow 400 further includes operation S410, operation S411, and operation S412.

In operation S4, an instruction that the verification result submitted by the client is passed is received by the target server, and verification code data and sampling data in the cache database are queried according to the unique identifier.

In operation S411, if the query result is normal, the service data submitted by the client based on the verification result is received.

In operation S412, if the query result is null, the receiving client is refused to submit the service data based on the verification result.

According to the embodiment of the disclosure, the verification code data and the sampling data in the cache database are queried, so that the accuracy of the verification result is judged, the verification result submitted by the client is prevented from being forged, and the security of the verification code data is improved.
