Abstract

The invention provides a click verification code identification method and a device, and a user terminal. The method comprises the following steps of in a verification code picture, acquiring the positioning information of all optional characters and acquiring a minimum screenshot containing the optional character in the verification code picture; carrying out character identification on each minimum screenshot and acquiring a character probability matrix; and according to the character probability matrix and the positioning information, determining a coordinate position corresponding to a target character in the optional characters. By using the click verification code identification method, an algorithm is simple, an operation period is short, identification efficiency is high, verification code identification accuracy is greatly increased, the method is convenient and practical, and great convenience is brought for a test engineer to test the safety of a website click verification mode.

Description

technical field

[0001] The present invention relates to the technical field of verification code testing, and more specifically, to a method, device and user terminal for point-and-click verification code recognition. Background technique

[0002] Verification code (CAPTCHA) is commonly used in web login interface. A well-designed verification code can be recognized manually, but it is difficult to be recognized by automatic tools, so as to protect the website from malicious use. Compared with the traditional input-type verification code, the point-and-click verification code has the advantages of high security and user-friendliness, and gradually replaces the traditional verification code and becomes the mainstream method.

[0003] In order to effectively block malicious access, many websites or clients have deployed corresponding verification code technology. Before the website goes online, the test engineer will identify the verification code of the website or client to...
