Fingerprint biometrics are probably the most common form of biometrics available today.    This form of data encryption has evolved out of the use of fingerprints for identification purposes over the last several decades.  By having an individual scan their fingerprint electronically to decode information, the transmitter of the data can be certain that the intended recipient is the receiver of the data.  When scanned electronically, fingerprints provide a higher level of detail and accuracy can be achieved over manual systems.

    Some other strengths associated with fingerprint biometrics are that giving fingerprints is more widely accepted, convenient and reliable than other forms of physical identification, especially when using technology.  In fact, studies have shown that fingerprint identification is currently thought to be the least intrusive of all biometric techniques.  One concern of fingerprint biometrics is that latent prints left on the glass will register the prior user, however there already exist units that will not scan unless a "live" finger is on the glass and will only register the later imprint.  Furthermore, the error rate experienced with this form of encryption is approximately one in one hundred thousand scans.

    Lastly, one of the most important features of fingerprint biometrics is its cost.  Scanners are already available fairly cheap and as the technology becomes more common this cost should only decrease.  In fact, in anticipation of widespread use of this technology in the future, some "mouse" manufacturers are developing their products with fingerprint scanner technology built right into the "mouse" itself.

    Closely associated with fingerprint biometrics is another biometric that registers the imprint left by the palm of the hand.  These types of scanners measure the geometry of the hand rather than the fine skin patterns as found in the finger tip.  Hand scanners have been used in apartment buildings, nurseries, and even the 1996 Olympic Village in Atlanta to control access to restricted areas.  These units are more commonly found in areas where dirt or debris on hands may make fingerprint identification difficult such as on shop floors in manufacturing plants.  Although palm print scanners nearly match fingerprint scanners in reliability, the units are much larger in size and cost than fingerprint scanners.  An average palm scanner can cost over $2,000.
