生物辨識技術專利資訊分析

A Patent Analysis on Biometrics Technology

生物辨識技術是未來資安技術的發展重心，自911恐怖攻擊事件之後，各國均積極推行相關計畫。本研究以專利分析方法，利用多項專利指標從國家、專利權人與技術領域等面向分析生物辨識技術之專利成長、技術影響力、科學強度與技術生命週期。主要結果顯示全球生物辨識技術專利件數持續成長，美國領先、日本次之；生物辨識技術與科學研究之關聯性較強，而指紋辨識為生物辨識最大宗技術；指紋、臉型辨識與技術通論發展已臻成熟，語音辨識技術變化較快。

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.
