The method comprises: an authentication server receives an authentication request from a client, generates a positioning factor string, and transmits generated information containing the positioning factor string and a structure of an all-element dynamic factor table to the client; the client receives the generated information, generates the all-element dynamic factor table, and maps the positioning factor string into the all-element dynamic factor table to acquire a dynamic graphical password inputted in accordance with a first positioning rule by a user and transmit to the authentication server; the authentication server receives the dynamic graphical password from the client, and if the first positioning rule corresponding to the parsed dynamic graphical password is consistent with a preset positioning rule, then the authentication is successful. The graphic passwords being visual and easy to remember, combined with the variability of one-time dynamic passwords, improves the overall convenience and security of an authentication system."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"One-time dynamic positioning authentication method and system and password alteration method","description":"Provided in the present application are a one-time dynamic positioning authentication method, system and password changing method.
