Provided in the present application are a one-time dynamic positioning authentication method, system and password changing method. 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.

One-time dynamic positioning authentication method and system and password alteration method

The present application provides a dynamic graphical password-based network registration method and system. The method includes: a server receives a registration request transmitted by a client, selects positioning factors from a positioning factor library based on a structure of a full-element dynamic factor table, generates positioning factor strings, and transmits the generated positioning factor strings to the client; the client generates full-element dynamic factor tables based on the structure of the full-element dynamic factor table and the positioning factor strings, wherein a user inputs two dynamic graphical passwords through the full-element dynamic factor tables, and transmits registration information including a user name and the positioning rules corresponding to the dynamic graphical passwords to the server; wherein if the registration information is correct, the positioning rule in the registration information is used as the password of the user. In the method, the input dynamic graphical password is used as the password stored for the user, which is securer, easy to remember, and hard to crack as compared with a conventional password consisting of fixed numerals or characters.
