no. 1 example

[0055] The first embodiment of the present invention provides a verification method, including the following steps:

[0056] Step S101, obtaining the receiving time of the generated instruction to obtain a time parameter;

[0057] The receiving time of the generating instruction in this step is specifically the receiving time of the verification code generating instruction. The receiving time may specifically be a time point, or may be a time period. For example, when a user needs to use a verification code for verification before entering a certain web page or performing a certain operation, the terminal will be triggered to send a generation command to the verification code generation module, and the verification code generation module will generate a verification code according to the generation command . The receiving time is the time when the generating module receives the generating instruction, or the time period used by the generating module to receive the generating...

Abstract

The invention discloses a verification method and a verification device. The method comprises the steps of obtaining the receiving time of a generation instruction, so as to obtain a time parameter; determining a verification code type corresponding to the time parameter based on the time parameter; generating a first verification code based on the verification code type; and receiving a second verification code to be verified, and verifying the second verification code based on the first verification code to obtain a verification result. According to the invention, the type of the verification code is determined according to the time parameter, and the time parameter is random and unfixed, so that the type of the verification code is random and unpredictable. The cracking difficulty of the verification code is improved, and the verification safety is improved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a verification method and device. Background technique [0002] In order to prevent batch registration, malicious cracking of passwords, swiping tickets, flooding forums, etc., it is a common practice for most websites to use verification codes for human-machine identification. [0003] In the existing verification methods, a single type of verification code is used for verification. For example, when using a digital verification code type for verification, the picture will be mixed with confusing curves and noise points. After the user recognizes the number on the picture, enter it into the verification code input box, and click the OK button to complete the verification. If the verification fails or the user clicks to refresh the verification code, the verification code image will be refreshed, and a new set of verification numbers will appear, and the user needs to repeat ...
