Embodiment 1

[0040] The embodiment of the present invention provides a method for verification code verification, which can be implemented jointly by the server and the terminal.

[0041] Such as figure 1 As shown, the processing flow of the server in the method may include the following steps:

[0042] Step 101: Generate a verification code picture containing selection condition information and characters in the picture content, and record locally the information of the character corresponding to the selection condition information among the characters contained in the verification code picture.

[0043] Step 102, sending the verification code picture to the terminal.

[0044] Step 103, when the verification information sent by the terminal is received, if the verification information matches the recorded character information, it is determined that the verification is passed, otherwise it is determined that the verification fails.

[0045] Such as figure 2 As shown, the processing fl...

Embodiment 2

[0051] The embodiment of the present invention provides a method for verification code verification, which can be implemented jointly by the server and the terminal. The terminal may be a terminal requesting a certain network service, and the server may be a background server of the network service.

[0052] Such as image 3 As shown, the processing flow of the method may include the following steps:

[0053] In step 301, the server generates a verification code picture including selection condition information and characters in the picture content, and records information of characters corresponding to the selection condition information among the characters contained in the verification code picture locally.

[0054]Wherein, the selection condition information is information that instructs the user to select characters in the verification code picture, and the selection condition information may be information in the form of text, such as Figure 4 "Please click all the le...

Embodiment 3

[0086] Based on the same technical idea, the embodiment of the present invention also provides a server, such as Figure 6 As shown, the server includes:

[0087] A generation module 610, configured to generate a verification code picture containing selection condition information and characters in the picture content, and locally record the information of the character corresponding to the selection condition information among the characters contained in the verification code picture;

[0088] A sending module 620, configured to send the verification code picture to the terminal;

[0089] The verification module 630 is configured to, when receiving the verification information sent by the terminal, if the verification information matches the recorded character information, determine that the verification has passed, otherwise determine that the verification has failed.

[0090] Preferably, the generating module 610 is configured to:

[0091] Selecting one selection condition ...

Abstract

The invention discloses a method, device and system for verification code verification, belonging to the technical field of the Internet. The method includes: generating a verification code picture containing selection condition information and characters in the picture content, and locally recording the information of the character corresponding to the selection condition information among the characters contained in the verification code picture; The verification code picture; when the verification information sent by the terminal is received, if the verification information matches the recorded character information, it is determined that the verification is passed; otherwise, it is determined that the verification fails. By adopting the present invention, the passing rate of malicious access can be reduced.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a method, device and system for verification code verification. Background technique [0002] With the rapid development of computer technology and Internet technology, the Internet has become one of the very important tools in people's daily work and life, and the types of network services and the number of users are increasing. In order to prevent the access of malicious software, the servers of various network services have set up a verification code verification mechanism. [0003] The general verification code verification mechanism is that the server sends a verification code picture to the terminal, and the verification code picture shows the characters of the verification code, and the terminal displays the verification code picture, and the user reads the verification code in the displayed verification code picture, and Enter the verification code in the input box,...
