Embodiment 1

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

[0041] Such as figure 1 As shown, the processing flow of the server in this 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 locally record information about characters corresponding to the selection condition information among the characters contained in the verification code picture.

[0043] Step 102: Send a 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 information of the recorded characters, 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 procedure...

Embodiment 2

[0051] The embodiment of the present invention provides a method for verification code verification, and the method can be implemented by a server and a terminal together. 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 containing selection condition information and characters in the picture content, and locally records the character information corresponding to the selection condition information among the characters contained in the verification code picture.

[0054] Among them, the selection condition information is information instructing the user to select characters in the verification code picture, and the selection condition information can be information in the form of text, such as Figure 4 "Please click all the let...

Embodiment 3

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

[0087] The generating module 610 is configured to generate a verification code picture containing selection condition information and characters in the picture content, and locally record information about characters corresponding to the selection condition information among the characters contained in the verification code picture;

[0088] The sending module 620 is configured to send the verification code picture to the terminal;

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

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

[0091] Select one selection condition informatio...

Abstract

The invention discloses a method, device and system for verifying a verification code, and belongs to the technical field of the Internet. The method comprises the steps: generating a verification code image, and locally recording character information, corresponding to selection condition information, in characters contained in the verification code, wherein the contents of the verification code image comprise the selection condition information and characters; transmitting the verification code image to a terminal; determining that the verification is passed if the verification information is matched with the recorded character information when the verification information transmitted by the terminal is received, or else, determining that verification is a failure. According to the invention, the passing rate of malicious access can be reduced.

Description

Technical field [0001] The present invention relates to the field of Internet technology, 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 is displayed in the verification code picture. The terminal displays the verification code picture. The user reads the verification code in the displayed verification code picture, and Enter the verification code in the input box. The terminal will...
