AUTHENTICATION METHOD AND AUTHENTICATION PROGRAM

摘要

To enhance the convenience of authentication when executing an application, an application server: acquires, from a terminal, context information indicating the status of the terminal; generates, on the basis of the acquired context information, information (an authentication necessity table) pertaining to the necessity for authentication when executing the application; and transmits to the terminal the authentication necessity table and an authentication module described in the table. Then, the terminal, on the basis of the authentication necessity table and an authentication table, determines whether or not authentication is necessary before executing the application, and when it has been determined that authentication is necessary, prior to executing the application, changes the authentication module read destination to the application read destination and executes the authentication module.

1. An authentication method comprising:
a step in which a server that provides a terminal device with an application acquires context information that indicates status of the terminal device from the terminal device; a step in which the server generates information about necessity for authentication on the basis of the context information acquired when executing the application; a step in which the server transmits the information about the necessity for authentication and an authentication module for executing authentication that is described as being needed in the information; a step in which the terminal device determines, before executing the application, whether the authentication is needed on the basis of the information about the necessity for authentication and history information about authentication performed in the past; and a step in which before executing the application, the terminal device changes a destination for reading the authentication module for executing the authentication that is determined as being needed by the step of determining to a destination for reading the application, and executes the authentication module.
