Information processing apparatus having user authentication function and authentication method

Abstract

The information processing apparatus includes first authentication portion, human body detecting portion, de-authentication portion, and second authentication portion. The first authentication portion shifts the state of the information processing apparatus to a login state in accordance with a predetermined first login operation. The human body detecting portion detects a human body within a predetermined range from the information processing apparatus. The de-authentication portion cancels the login state when a human body is not detected by the human body detecting portion during the login state. The second authentication portion shifts the state of the information processing apparatus to the login state in accordance with a second login operation involving less operation steps than the first login operation after the login state is canceled by the de-authentication portion.

Dependencies are inferred from the claim text.
