ABSTRACT:
A security enhancement for laptop computers comprises the use of a moving visible area and an obscured area for the laptop screen. The visible area may be defined by the user to comprise a single word, a single line, or a plurality of lines of data. The obscured area may comprise all remaining space on the laptop screen not defined as the visible area, A user may specify that the obscured area be completely hidden from view (i.e.., such as by blackening or whiting out the area) or difficult to view by others. The present invention is particularly useful with a laptop computer in a crowded environment such as while travelling on an airplane. The present invention will reduce the likelihood of unauthorized viewing of possibly sensitive computer data by others.
