Abstract: A display apparatus and a method for operating the same are disclosed. The method for operating a display apparatus includes acquiring biometric information about a user through a camera or a sensor unit, comparing the acquired biometric information with pre-stored authentication information, and switching the display apparatus to a first mode, if the acquired biometric information does not match with the pre-stored authentication information, the first mode restricting access to content predetermined from total content.
