Point contact type verification code automatic identification method based on LeNet and SSD

Abstract

The invention discloses a point contact type verification code automatic identification method based on LeNet and SSD. The method comprises the following steps: the step 1, capturing a request and a response of a verification code recognition process by using package capturing tools such as Charls, analyzing a response structure, realizing recognition text acquisition and image acquisition by using HttpURLConnection, simulating automation of a fragment graph synthesis process by referring to javascript, and finishing automation of web interaction; and the step 2, taking advantages of Matlab processing matrix image, using .m processing image DBSCAN clustering, binarization, dilatation expansion, output of images to be recognized and other functions, and packaging the images into a jar fileto be called by an automation program. According to the SSD and LeNet-based point contact type verification code recognition method, the characters of the point contact type verification code and thepositions of the characters in the background image can be automatically recognized, the verification process is completed through a series of web automatic interactions, and This method continuouslyimproves recognition precision according to the deep self-learning reinforcement of use.

Description

technical field [0001] The invention relates to the technical field of computer information processing, in particular to a method for automatically identifying point-touch verification codes based on LeNet and SSD. Background technique [0002] At present, when we use a browser to access a website or use an organization's internal business system, there are many business scenarios that require login to identify the user's identity. Software developers usually add human-computer interaction to prevent users from maliciously logging in and using the system. With the rapid development of technology, the form of human-computer interaction verification is constantly upgrading, especially various verification code technologies are also constantly being strengthened. In addition to character recognition verification codes, slider drag verification codes, picture touch verification codes, and quiz answers etc. [0003] The character verification code usually displays multiple disto...

Problems solved by technology

However, the existence of the verification code, for third-party testing, RPA (that is, Robotic Process Automation software process automation, refers to the use of software automation to realize the business that is originally done by manually operating computers in various industries), and scientific research units can effectively collect scientific research data on a large scale , Open up multiple systems within the organization and other work caused trouble

However, the shape, size, color and position of the fused text of the point-touch verification code are highly variable, and its recognition accuracy is difficult to guarantee, and the efficiency of the existing sliding verification is low.
