Abstract
A user terminal apparatus with a security function and a security-control method are provided, which may prevent unauthorized use of the user terminal apparatus without requiring a user to lock up the user terminal apparatus. The user terminal apparatus includes an input sensing unit which senses a user's input to the user terminal apparatus, an information collecting unit which collects information regarding an input state, which is determined based on the user's input, and a transition of the determined state, and a security-control unit which determines whether the user is valid based on the collected information and controls a security function.
