Technical Field

The invention relates to the technical field of a real person verification method, in particular to a real person verification method based on mouse track data analysis.

Background

With the development of computer programs, more and more programs/scripts are presented to browse web pages and obtain data. In the traditional method for verifying the real person, a device for browsing a webpage and data collected from external devices such as a mouse, a keyboard and the like are processed and analyzed, so that whether the real person browses or not is judged. The traditional real person verification method generally comprises four types: 1) answer letters and numbers in pictures; 2) selecting a correct picture; 3) collecting hardware information, calculating and detecting hardware performance and IP address for judgment; 4) and dragging the picture to a specified position horizontally or vertically.

In the prior art, with the development of programs and scripts, the traditional human verification method gradually exposes some problems: firstly, the question is single and is easy to be cracked by a picture recognition program; secondly, the problem is too complex, which causes great influence on the normal users; thirdly, the number of hardware information bases is huge and continuously increases, the IP address owned by a computing center (server provider) continuously changes, and if the latest information cannot be collected immediately, misjudgment is caused; fourthly, the dragging process is simple, and the detailed mouse track is difficult to collect for further analysis.

Disclosure of Invention

The invention aims to overcome the problems in the prior art, and provides a real person verification method based on mouse track data analysis, which can judge whether a browser user is a real person or a program/script, and avoid the burden on a normal user due to an over-complex question.

In order to achieve the technical purpose and achieve the technical effect, the invention is realized by the following technical scheme:

a real person verification method based on mouse track data analysis comprises the following steps:

1) the client sends a security verification request to a verification picture platform;

2) receiving a verification picture sent by the verification picture platform, wherein the verification picture comprises a mathematical calculation verification question requiring a user to drag a correct answer to a designated area, and the correct answer of the mathematical calculation verification question consists of numbers;

3) when a user answers, acquiring answer information and mouse track data information of a mouse on a verification picture;

4) verifying according to the answer information and the mouse track data information;

5) if the verification result is that the service request is successful, response information indicating that the service request is successful is sent to the client; and if the verification result is that the service request fails, sending response information indicating the failure of the service request to the client.

Further, in step 2), the mathematical calculation verification problem is an addition, subtraction, multiplication and division calculation problem within 100; the dragging of the answer of the mathematical calculation verification question involves multiple directions, not single horizontal or vertical direction dragging.

Further, in step 2), at least three draggable digits are included in the verification picture.

Further, in step 4), the step of verifying sequentially includes determining whether the answer is correct, determining whether the number of collected points in the dragging track is proper, determining whether the interval between the collected points in the track is proper, determining whether the interval between the numbers is sufficient when the answer is composed of two or more numbers, determining whether the interval between the collected points in the track is sufficiently different from the interval between the collected points in the track, determining whether the dragging track continuously reaches the ending position from the starting position, determining whether the slope of a line segment formed between the points is sufficiently different, terminating the next step of verifying when any one of the above-mentioned step results is "no", and feeding back the verification result that the verification result is failed; and when the results of the verification steps are yes, generating a line graph of the slope and solving a regression equation of the line graph to further solve a fitting curve of the line graph, judging whether the slope of the fitting curve is gradually increased or gradually decreased, if the result is no, feeding back the verification result, and if the result is yes, feeding back the verification result, wherein the feedback verification result is passed.

Furthermore, a fitting curve is obtained to remove the noise data, and whether the slope of a line segment formed by the points in the track is larger or smaller is judged.

The invention has the beneficial effects that:

1) the picture is not used as the only basis for verification, and the verification cannot be passed even if the correct answer is found through picture identification.

2) The invention does not need to collect information of hardware, browser, IP and the like of the user, and does not need to calculate to test hardware performance, thereby reducing cost.

3) The method is mainly based on mouse track data analysis for verification, so that the set questions are simple, and the normal users are not burdened.

Of course, it is not necessary for any one product that embodies the invention to achieve all of the above advantages simultaneously.
