Objective: To analyse the pattern asymmetry (the discordance of fingerprint patterns between homologous fingers on the right and left hand), and the pattern complexity index (the number of whorls subtracted by numbers of arches).
Method: One thousand and five Thai university students (M:F = 525:480) were obtained fingerprints by using the fingerprint scanner and the çautomated inkless fingerprint imaging softwareé, which is able to collect quickly and store high-quality electronic file of fingertip images. Each finger pattern was characterized into 4 types: arch, radial loop, ulnar loop, and whorl.
Results: Mean scores of the pattern asymmetry among male and female subjects were 1.08 (S.D.=1.01), and 1.27 (0.98), respectively; the pattern complexity index was 4.59 (3.56) among
male and 4.01 (3.72) among female subjects which is significantly different.
