A verification code identification input method and system based on sliding verification

Abstract

The invention provides a verification code identification input method and system based on sliding verification. The method includes: finding out the position of a mosaic and obtaining a picture 1 through the screenshot function of selenium+phantomjs; automatically identifying and controlling the slider in the mouse cursor point, and performing screenshot to get a picture 2 after a time thresholdis set; carrying out image processing and recognition on the picture 2 to obtain a contrast picture 3; calculating that center distance of the black region in the picture 3, and obtaining the distancen to be displaced by the mouse; according to the distance n, outputting the most real sliding track of human through the analysis of the moving track of real human mouse; increasing the random valueof some moving points according to the mouse simulation moving trajectory; phantomjs simulating the mouse trajectory, and the mouse clicking on the slider to simulate real human sliding. Compare withthat prior art, the method and the system have the advantages that the automatic identification of the sliding authentication code is carried out simply and accurately, and the blocking effect of thesliding authentication code on the traffic flow is solved.

Description

technical field [0001] The invention relates to a verification code identification input method and system based on sliding verification, belonging to the field of the Internet. Background technique [0002] The sliding module verification method can analyze the behavioral characteristics of the user in the process of completing the jigsaw puzzle, and judge whether it is a human or a machine through data analysis. It can comprehensively monitor suspicious machine attacks, and the characteristics of the entire network are dynamically updated every 30 minutes to quickly respond to emergencies. Up to 5 layers of heterogeneous security model filters to protect website security from multiple angles. At the same time, users do not have to face dazzling English characters or Chinese characters. Compared with traditional digital, text, and character-type verification codes, it is more humane, and the user verification time is shorter and more interactive. This new verification serv...

Problems solved by technology

The random forest method needs to use a series of algorithms and mathematical formulas to obtain trajectory parameters and submit them to the server, and the operation is cumbersome and complicated

[0005] In order to pass the sliding verification rules smoothly, a verification code input system, such as a coding system, is used in the existing industry, and the interfaces required for verification are concentrated in the system. Manual verification requires a lot of manpower and time costs.

Due to the uncontrollable factors of manual operation behavior, the business flow often increases the waiting time or even terminates in the sliding verification link, making the automatic business process passive, and the verification code input system has high management costs and low efficiency, and urgently needs technical improvement.

[0006] The sliding verification code is based on the response time, dragging speed, time, location, trajectory, and number of retries of people interacting with the slider to evaluate the risk. Some current sliding verification technologies automatically pass the technology, such as by recording the sliding track. At the same position, use trajectory array replay, single sliding trajectory, easy to perform too mechanized in terms of dragging speed and time, it is judged as machine behavior operation, low efficiency and low pass rate
