Abstract
A portable terminal and a method for protecting a displayed object on a screen of a portable terminal are provided. The method includes detecting an input on the screen; forming an area corresponding to a position of the detected input; and displaying a part of an object corresponding to the formed area differently from another part of the object in an area outside of the formed area.
Claims17
A method for protecting an object displayed on a touch screen of a portable terminal, the method comprising:
- activating a security mode based on analyzing an ambient situation around the portable terminal;
- displaying a trace based on a movement of a touch input by an input device on the touch screen while the security mode is activated;
- controlling the display of the trace such that the displayed trace sequentially disappears, wherein the trace includes a plurality of segments in which each of the plurality of segments sequentially disappears one at a time;
- identifying a hovering input by the input device on the trace which is disappearing sequentially;
- identifying a size of an area having a portion of the trace based on a position at which the hovering input is identified;
- and
- re-displaying the portion of the trace corresponding to the identified hovering input within the area having the identified size.
A portable terminal for protecting an object displayed on a touch screen of the portable terminal, the portable terminal comprising:
- a touch screen;
- and
- at least one processor configured to:
- activate a security mode based on analyzing an ambient situation around the portable terminal,
- control the touch screen to display a trace based on a movement of a touch input by an input device on the touch screen while the security mode is activated,
- control the touch screen to control the display of the trace such that the displayed trace sequentially disappears, wherein the trace includes a plurality of segments in which each of the plurality of segments sequentially disappears one at a time,
- identify a hovering input by the input device on the trace which is disappearing sequentially,
- identify a size of an area having a portion of the trace based on a position at which the hovering input is identified,
- control the touch screen to re-display the portion of the trace corresponding to the identified hovering input within the area having the identified size.
A non-transitory computer-readable storage medium for storing instructions for a processor to protect an object displayed on a touch screen, which when executed by the processor, performs the instructions including:
- activating a security mode based on analyzing an ambient situation around the portable terminal;
- displaying a trace based on a movement of a touch input by an input device on the touch screen while the security mode is activated;
- controlling the display of the trace such that the displayed trace sequentially disappears, wherein the trace includes a plurality of segments in which each of the plurality of segments sequentially disappears one at a time;
- identifying a hovering input by the input device on the trace which is disappearing sequentially;
- identifying a size of an area having a portion of the trace based on a position at which the hovering input is identified;
- re-displaying the portion of the trace corresponding to the identified hovering input within the area having the identified size.
