Outline of Final Research Achievements

Biometric individual identification techniques such as fingerprint pattern recognition are widely used. The aim of this study is to develop a highly cost-effective, non-invasive method for the distinction of identical twins. As a new technique, we have developed the HFECG (high frequency component of ECG) identification system. In this report, we proposed the application of this technique to distinguishing identical twins. Identification tests were performed with a neural network based system. Three pairs of identical Japanese twins in their twenties served as the test group while another 130 unrelated healthy Japanese individuals in their twenties served as the control group. Each of their heartbeats were detected and compared using this new method.
The result with the three pairs of identical twins was 100% accuracy. There were no difference in discrimination accuracy between the sets of identical twins and the normal unrelated controls.
