Vein and Fingerprint Identification Multi Biometric System: A Novel Approach

摘要

In this paper, a compact system that consists of a Biometrics technology CMOS fingerprint sensor (FPC1011F1) is used with the FPC2020 power efficient fingerprint processor ; which acts as a biometric sub-system with a direct interface to the sensor as well as to an external PC for storing finger print templates. The small size and low power consumption enables this integrated device to fit in smaller portable and battery powered devices utilizing high performance identification speed. Added to the fingerprint system in a vein image extraction system; it consists of a set of LEDs (light emitting diodes) that generates near infrared light that penetrates the body Tissue. An image of the veins pattern is revealed as the near infrared light is reflected in the haemoglobin in the blood. A CCD (charge coupled device) camera uses a small, rectangular piece of silicon to receive incoming light. The CCD captures the image of the vein pattern through this reflected light. The Image is processed through an algorithm to constructs a finger vein pattern from the camera image. This pattern is then digitized and saved as a template for biometric authentication the integrated system will extract two biometrics identifiers; namely, vein and fingerprint.
