<p>Biometric measuring apparatus for recognizing a person's identity based on measurements performed on the person's hand. An arrangement for producing (11) and storing (13) a silhouette image of at least a portion of a person's hand is combined with an arrangement for producing (11) and storing (21A) a displacement image of the same portion of a person's hand which can be correlated (30) with said stored silhouette image to provide measurement data on finger height characteristics. An analyzing device analyzes said stored silhouette image and said stored displacement image to produce hand feature data, including hand feature data derived at least in part from finger height characteristics. A comparing device (60) compares hand bid data with hand enrollment data to decide on the basis of prearranged decision criteria whether said hand bid data and said hand enrollment data were produced by the same hand portion.</p> |
