Features that simplify your life, keep your Finger on it
A fingerprint looks at the patterns found on a fingertip. There are a variety of approaches to fingerprint verification. Some emulate the traditional police method of matching pattern; others use straight minutiae matching devices; and still others are a bit more unique, including things like more finger patterns and ultrasonic characteristics. A greater variety of fingerprint devices is available more than any other biometric technology.
How it works: Fingerprint systems translate illuminated images of fingerprints into digital code for further software such as enrolment (fingerprint registration) and verification (authentication or verification of registered users).
The scanner uses an advanced CMOS image sensor to capture high contrast, high resolution fingerprint images which are virtually distortion-free. A series of powerful algorithms extract data from the image, mapping the distinguishing characteristics of the fingerprint.
This data is then converted into an encoded binary string known as a digital template, and stored in a database. The actual fingerprint image is never stored.
To identify or verify a fingerprint, a proprietary matching algorithm compares the new template made from the extracted characteristics from the input fingerprint on the optical module to a previously stored sample. The entire matching process takes roughly one second. Authentication takes place locally at the device or on a server, depending on system configuration.
Finger vein recognition
A method of biometric authentication that uses pattern-recognition techniques based on images of human finger vein patterns beneath the skin's surface. Finger vein recognition is one of many forms of biometrics used to identify individuals and verify their identity.
Finger Vein ID is a biometric authentication system that matches the vascular pattern of an individual's finger to previously obtained data. The technology is currently in use or development for a wide variety of applications, including credit card authentication, automobile security, employee time and attendance tracking, computer and network authentication, end point security and automated teller machines.
To obtain the pattern for the database record, an individual inserts a finger into an attester terminal containing a near-infrared LED (light- emitting diode) light and a monochrome CCD (charge-coupled device) camera. The hemoglobin in the blood absorbs near-infrared LED light, which makes the vein system appear as a dark pattern of lines. The camera records the image and the raw data is digitized, certified and sent to a database of registered images. For authentication purposes, the finger is scanned as before and the data is sent to the database of registered images for comparison. The authentication process takes less than two seconds.
Blood vessel patterns are unique to each individual, as other biometric data such as fingerprints or the patterns of the iris. Unlike some biometric systems, blood vessel patterns are almost impossible to counterfeit because they are located beneath the skin's surface. The finger vein ID system can only authenticate the finger of a live person.
