A system (method and apparatus) for verifying/identifying a person based on contour of the knuckle surface of at least one hand, e.g. a digitized waveform unique to each individual. At an Enrollment Station a microcomputer is connected to a device for identifying the knuckle surface profile (e.g. a video camera or electromechanical contour sensing device). A candidate user grasps a grip handle, preferably vertically oriented, on the apparatus, positioning a fist before a viewing window and activating the device to scan or assess the fist and generate a contour of the user's knuckle surface contour. User's data comprises a knuckle contour, an assigned PIN, and optionally, information such as user's name, bank ID number, Social Security Number, and access restrictions. User's data may be stored as a profile (template) in an ID card, and/or in a master database containing data of all authorized users in a guarded system.

[ What is claimed is:] [1.] A biometric hand geometry method for preparing a unique identity characteristic of a user based on at least one fist in grip configuration by creating and storing as a template a reference profile of the undulating peaks and valleys of a knuckle surface contour unique to each user, the method comprising the steps ofa) positioning the user's knuckles of said one fist with respect to a device which captures the undulating contour of the knuckle and interphalangeal joint surfaces,b) scanning the surface of the knuckles, the successive scan lines running from the interphalangeal joints to a position on the knuckle,c) extracting the knuckle surface contour as a smooth curve defined as a sequence of discrete points on the knuckle contour,d) storing the knuckle surface contour as a template in a storage medium.
