Abstract
A mobile information terminal includes a mode acquisition section adapted to acquire the mode of the mobile information terminal; a sample filling section adapted to, when the number of gripping feature samples acquired in a mode is insufficient, fill in lacking gripping feature samples with gripping feature samples acquired in another mode; a gripping-feature sample acquisition section adapted to acquire gripping feature samples; a switch adapted to switch the mobile information terminal between a learning state and an authentication state; a template learning section adapted to learn an authentication template in each mode using the gripping feature samples when the mobile information terminal is in the learning state; an authentication section adapted to compare the learned authentication template with gripping feature samples in each mode to perform authentication; and a locking section adapted to lock some or all of functions of the mobile information terminal when the authentication fails.
