BIOMETRICAL IDENTIFICATION ON THE BASIS OF PHOTOPLETHYSMOGRAM FOR AUTOMATED MEDICAL SYSTEMS

Abstract

Nowadays, modern digital integration requires all personal databases to have reliable protection. It concerns automated diagnosis and lab research of biological materials systems the most. Each step of the way creates a high risk of losing or replacement of information, which leads to incorrect diagnosis, or even falsification for further illegal use. Biometrical identification is able to solve many protection issues, since the important information is always tied to a person, and is not usable by different people with malicious intent, be it stealing or replacement. Biometry is a way to identify and authenticate a person by measuring their physiological parameters, which makes biometrical control one of the better ways for identification. This research is a look into different ways to identify a person by means of biological signals using plethysmography. This research was conducted using a biometrical measurement system KL-720 using a photo sensor, which easily registers on different parts of a human body a finger, an ear, a hand or an arm. It’s ease of use, low price and small size makes it the prime choice.
