Abstract:
1. A display device comprising: a display unit configured to display an image and to sense a touch input; a sensor unit configured to sense a fingerprint from the touch input on the display unit; a storage unit configured to store data; and a processor configured to control the display unit, the sensor unit, and the storage unit, wherein the processor is further configured to: provide feedback for indicating a security on state of first information when a touch input for selecting the first information is detected, detect a security off input when the touch input for selecting the first information is detected during a first period, obtain the fingerprint continuously during the first period when the security off input is detected, convert the security on state of the first information to a security off state when the obtained fingerprint is matched with a pre-stored fingerprint during the first period, detect a security maintenance input when the touch input is released after a second period, and maintain the security on state of the first information when the security maintenance input is detected in response to the feedback, wherein the first period is longer than the second period.
