Abstract

The invention provides an input-free dynamic verification code implementation method. The method comprises the following steps: firstly, generating a tenable verification code library and an invalid verification code library at a server; secondly, when a user inputs an account number and a password at a client side, the server randomly extracting N verification codes from the tenable verificationcode library and the invalid verification code library to establish a verification code set, displaying one verification code in the verification code set in a verification code box of the client; andfinally, judging whether the logicality of the current verification code is correct or not, if not, waiting for automatic updating of the verification code by the user, and if yes, clicking submission by the user to perform a next operation interface to finish verification of dynamic verification. According to the method and the system, judgment can be carried out when a user sees the verification code, redundant input operation is not needed, the complexity of application interaction is reduced, a time length factor is increased by utilizing an extraction algorithm and a sorting algorithm when continuous identification of the verification code fails, the cracking difficulty of the client in unit time is improved, and the safe operation of the client is ensured.

Description

technical field [0001] The invention relates to the technical field of verification codes, in particular to an input-free dynamic verification code realization method. Background technique [0002] In today's Internet applications, dynamic verification codes have been widely used. Its main purpose is to solve malicious logins or attacks. However, current users find the correct verification code from blurred pictures and enter it into the solution of the application system, which is an additional solution for users. Brings input operations, and even complex judgment operations. In today's special emphasis on user experience, it seems very out of date. Contents of the invention [0003] Aiming at the technical problem that the current verification code verification method is complicated to operate, the present invention proposes an input-free dynamic verification code implementation method. After the user enters the password, he can immediately judge and immediately press E...
