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...
