Abstract
A password-type security system may be employed using the placement of physical objects as a security pattern that is to be matched before access to secured content is granted. The system may be implemented on a computing system that uses a display that can detect, e.g., via optical circuitry, the visual characteristics of the display surface. The system can visually detect the placement of objects, their orientations, locations, color, printed patterns, etc. The user may define a security pattern as comprising one or more objects placed at locations on the screen, or at a predetermined rotation angle. The outline shape of an object may be treated as a required pattern, such that access to secured content is permitted only if the object having that outline shape is detected on the display surface. Similarly, printed patterns on objects may also be detected and used as part of security patterns.
