Methods, apparatus and security systems for uniquely identifying individuals by their particular physical characteristics are provided. In particular, facial parameters which are defined as being the distances between identifiable points on the human face, and/or ratios of the facial parameters can be used to identify an individual as the parameters for each individual are unique. Thus, by coding the parameter and/or parameter ratio information of an individual on a card, and by scanning the face of the presenter of that card to obtain parameter and/or parameter ratio information of the presenter, a determination can be made as to whether the presenter is that individual whose information is on the card. Particular parameters such as the distance between the eye retinae, the distance from each eye retinae to the nose bottom and to the mouth center, and the distance from the nose bottom to the mouth center are set forth, as they may be particularly defined due to the shadowed definable points at each end. |
