Biometric Security - Fingerprint Access
In traditional fingerprint access systems, an individual attempting to access a protected resource places their finger on a fingerprint sensor/reader at an access point such as a door or computer. The sensor reads the fingerprint and transmits the image, typically to a server, where it is compared against a database of stored fingerprints. If the live print matches a stored print, the individual is permitted access.
Fingerprint entry systems represent significant security advancements over proximity cards or passwords because they physically prove each user's identity
Security personnel look for biometric data that does not change over the course of your life; that is, they look for physical characteristics that stay constant and that are difficult to fake or change on purpose.
Fingerprints remain constant throughout life. In over 140 years of fingerprint comparison worldwide, no two fingerprints have ever been found to be alike, not even those of identical twins. Good fingerprint scanners have been installed in PDAs like the iPaq Pocket PC; so scanner technology is also easy. This method might not work in industrial applications since it requires clean hands.
Fingerprint identification involves comparing the pattern of ridges and furrows on the fingertips, as well as the minutiae points (ridge characteristics that occur when a ridge splits into two, or ends) of a specimen print with a database of prints on file.

Biometric Security – Retinal Scan


A retinal scan is a biometric technique that uses the unique patterns on a person's retina to identif them.
Used almost exclusively in high-end security applications, the retinal scan uses a low-intensity light source and a delicate sensor to scan the pattern of blood vessels at the back of the retina, a pattern unique to each individual.
There is no known way to replicate a retina. As far as anyone knows, the pattern of the blood vessels at the back of the eye is unique and stays the same for a lifetime. However, it requires about 15 seconds of careful concentration to take a good scan. Retina scan remains a standard in military and government installations.

Biometric Security – Hand Scan

Palm print recognition inherently implements many of the same matching characteristics that have allowed fingerprint recognition to be one of the most well known and best publicised biometrics. Both palm and finger biometrics are represented by the information presented in a friction ridge impression. This information combines ridge flow, ridge characteristics and ridge structure of the raised portion of the epidermis. The data represented by these friction ridge impressions allows a determination that corresponding
areas of friction ridge impressions either originated from the same source or could not have been made by the same source.

Because fingerprints and palms have both uniqueness and permanence, they have been used for over a century as a trusted form of identification. However, palm recognition has been slower in becoming automated due to some restraints in computing capabilities and live scan technologies.
