Abstract
A surface shape recognition apparatus includes detection circuit, comparison circuit, storage circuit, and control circuit. The detection circuit electrically detects a surface shape pattern in a partial region of the target collation surface of an object using a plurality of sensor elements and outputs detection data representing the surface shape pattern. The comparison circuit compares the detection data from the detection circuit with predetermined collation data and outputs a comparison result. The storage circuit stores template data representing the surface shape pattern of the entire target collation surface, the template data being obtained from the object in advance. The control circuit partially reads out, as collation data, the template data stored in the storage circuit from an arbitrary position, outputs the collation data to the comparison circuit, and performs determination for authentication between the template data and the object on the basis of the comparison result from the comparison circuit. A surface shape recognition method is also disclosed.
