Biometrics is the future information technology in focus. After the 9/11 terrorist attacks, nations worldwide have actively engaged in developing biometrics schemes. The methodology developed for this empirical study is quantitative analysis which uses patent indicators to analyze biometrics development trends. The study aims to analyze biometrics patent growth, technology impact, science strength and technology cycle time in country, assignee and technology aspects. Bibliometric analysis on USPTO patents shows that the patent numbers of biometrics worldwide continue to increase, which the US leads and Japan follows. Biometrics has stronger linkage with scientific research and fingerprint recognition serves as the major biometrics technology. Fingerprint, facial and general technology recognition are in the mature stage of technology development, whereas voice recognition has faster technology cycle time.
