What is the primary function of Hand Geometry in biometric controls?

To analyze the temperature of the hand

To measure specific points on the subject's hand

The primary function of Hand Geometry in biometric systems is to measure specific points on the subject's hand. This method involves capturing the unique geometric features of an individual's hand, such as the length and width of the fingers, the overall size and shape of the hand, and the distances between various reference points. This data is then used to create a biometric template that can accurately identify or verify an individual's identity based on the distinctive characteristics of their hand.

The measurement of specific points allows for the development of a unique profile for each individual, which is crucial for effective biometric identification and authentication. Hand geometry does not focus on qualitative characteristics like temperature or detailed imaging, but rather quantifiable measurements that can reliably distinguish one person from another. This specificity is what makes hand geometry a viable option in biometric access control systems.
