Individual Biometrics 

VASCULAR PATTERNS 

 

Basics:

 Vascular patterns are best described as a picture of the veins in a person's hand or face. The thickness and location of these veins are believed to be unique enough to an individual to be used to verify a person's identity.  

  

  

How it Works:

 The most common form of vascular pattern readers are hand-based, requiring the user to place their hand on a curved reader that takes an infrared scan. This scan creates a picture that can then be compared to a database to verify the user's stated identity.  

  

  

History:

 Vascular pattern technology is still fairly new and there are few published details about it.  

  

 

  

Use:

 Though minimally used at the moment, vascular pattern scanners can be found in testing at major military installations and is being considered by some established companies in the security industry and multi-outlet retailers. Currently it is still building acceptance.  

  

  

Evaluation:

 Too new to have much data, vascular pattern technology does seem to have a few advantages over its counterparts, including the great difficulty in emulating another person's vein structure, and not having to worry about rain, glasses, or external injuries. That said, effects of aging, heart attacks, and medical problems with one's arteries on the scans has yet to be determined fully. It also requires a large amount of space to mount the device si that the entire hand can be scanned which may restrict its usability.
