Network registration method and system based on dynamic graphic password

Abstract

The invention discloses a network registration method and system based on a dynamic graphic password. The method includes: a server receives a registration request sent by a client, selects a positioning factor in a positioning factor library according to the structure of a dynamic factor table of all elements, and generates a positioning factor. factor string, and send the generated positioning factor string to the client, and the client generates a full-factor dynamic factor table according to the structure of the full-factor dynamic factor table and the positioning factor string, and the user inputs two parameters through the full-factor dynamic factor table. Set a dynamic graphic password, and send the registration information including the user name and the positioning rule corresponding to the dynamic graphic password to the server; if the registration information is correct, use the positioning rule in the registration information as the user's password . In this method, the input dynamic graphic password is used as the password stored by the user, which is safer, easier to remember and difficult to crack than the traditional password composed of fixed numbers or characters.

Description

technical field

[0001] The invention relates to the technical field of network security, in particular to a network registration method and system based on a dynamic graphic password. Background technique

[0002] With the development of Internet technology, there are more and more websites that can provide Internet services. In order to obtain the services provided by these websites, users need to log in to the target service website through a network terminal, and further access the target service website to obtain the target service. Services Provided by the Site. In order to ensure the security of network access, the target service website must authenticate the user on the network terminal side. The information used for identity authentication is usually closely related to registration information. In other words, the user's registration method directly affects the information and rules used for user identity authentication, further affecting the security of network ac...
