Abstract
A degree of security set for an application and a valid time corresponding to the degree of security are stored in a memory. When an authentication unit performs user authentication using a fingerprint image input through an authentication information input unit and authorizes use of the application by the user, a control unit monitors lapse of the valid time corresponding to the application. When the valid time expires, the control unit request the user to input authentication information, and authentication is repeated at the authentication unit.
Claims11
An information processing apparatus, comprising:
- a storage unit storing a degree of security set for a function of the information processing apparatus, and a function valid time corresponding to said degree of security;
- an authentication information obtaining unit obtaining authentication information as a piece of information for identifying a user;
- an authentication unit authorizing use of said function by said user, using said authentication information;
- and
- a control unit requesting, when it is detected that the function valid time corresponding to the degree of security set for said function has elapsed since the start of use of said function, said authentication information and causing said authentication unit to execute said authentication.
In an information processing apparatus storing a degree of security set for a function and a function valid time corresponding to the degree of security, a method of authentication, comprising:
- authentication information obtaining step of obtaining authentication information as information for identifying a user;
- authentication step of authorizing use of said function by said user using said authentication information;
- and
- control step of requesting, when it is detected that the function valid time corresponding to the degree of security set for said function has elapsed since the start of use of said function, said authentication information and executing said authentication.
A program product causing an information processing apparatus to execute an authentication process, wherein
- said information processing apparatus stores a degree of security set for a function and a function valid time corresponding to the degree of security;
- said authentication process including
- authentication information obtaining step of obtaining authentication information as information for identifying a user;
- authentication step of authorizing use of said function by said user using said authentication information;
- and
- control step of requesting, when it is detected that the function valid time corresponding to the degree of security set for said function has elapsed since the start of use of said function, said authentication information and executing said authentication.
