Embodiment 1

[0059] An embodiment of the present invention introduces an interactive picture verification method based on semantic understanding.

[0060] Combine below figure 1 The basic flow of an interactive picture verification method based on semantic understanding according to an embodiment of the present invention is described. Such as figure 1 As shown, the main implementation steps of the method are as follows:

[0061] 1. Generate questions to be verified

[0062] The verifier (server) is provided with a base attribute library for generating questions to be verified. Each attribute can be selected from the basic attribute library according to different scenarios. This attribute determines the various meanings contained in the question to be verified. The user needs to understand the meaning of the question before entering the verification code correctly. The basic format of the question to be verified is:

Abstract

The invention belongs to the technical field of network verification, and discloses an interactive picture verification method based on semantic comprehension, which comprises the following steps: 1)generating a to-be-verified problem: randomly selecting a plurality of attributes from a basic attribute library for generating the to-be-verified problem, and randomly setting attribute values of theattributes; generating a to-be-verified problem according to the selected attribute and attribute value; 2) generating a specified number of verification pictures according to attributes and attribute values corresponding to the to-be-verified problem, generating a verification picture output sequence, generating non-verification pictures, and forming candidate code pictures according to the verification picture output sequence; 3) displaying the to-be-verified problem and the candidate code picture; 4) receiving pictures clicked by the user in the candidate code pictures, and recording a position sequence of the clicked pictures; and 5) comparing the position sequences of the verification picture output sequence and the click picture, if the position sequences are the same, the verification is passed, If the position sequences are different, the verification is not passed. The to-be-verified problem and the candidate code picture generated by the method are easy to identify and operate by a user, but are not easy to automatically identify by a machine.

Description

technical field [0001] The invention belongs to the technical field of network verification, and in particular relates to an interactive picture verification method based on semantic understanding. Background technique [0002] Captchas are used during network verification to distinguish whether an access requester is a computer program or a person. In network verification, the computer as the server will automatically generate a question to be verified for the user to answer. This question to be verified can be generated and judged by a computer, but only a human can answer it. Since the computer cannot answer the question to be verified (feedback the correct verification code to the computer), the user who answers the question to be verified can be regarded as a human being. Verification codes are often used to prevent Trojan horses and other programs from maliciously cracking passwords, swiping tickets, and flooding forums. The verification code is usually composed of ...
