生物特徵辨識在各項領域的應用方式，近年來已有相當多的研究成果，其中臉部比對辨識技術近年來日益成熟，在影像光源、角度均符合基本需求的前提下，比對準確率已大幅提升，所需比對時間亦縮短許多。自從911恐怖攻擊事件發生後，各國政府即開始加速研究，不斷投入人力將人臉辨識比對技術應用於國土安全、入出境管理及治安維護等各項工作領域。我國警政治安機關―內政部警政署自2009年起亦陸續投入人臉辨識技術之驗證及比對系統開發建置工作，迄今已獲得初步成果，對於各警察機關執行犯罪偵查、維護秩序、協尋人口及查證身分等法定任務，可預見將有龐大助益。將來實務運用上，倘能進一步結合各地監視錄影系統及現行警用行動載具，結合後端平台雲端運算技術即時回傳比對結果，將可更貼近第一線員警實務使用需求，發揮警政治安維護之效能。

The applications of biometric techniques to different fields have reached fairly many research achievements in recent years. Among these fields, facial recognition technology has been greatly improved upon. Under the premises that images' illuminant and angle can meet certain basic needs, the verification accuracy rate has greatly risen along with verification time being vastly reduced. Since the 9/11 attacks, governments all over the world have improved funding towards this field, whilst continuously attempting to implement this technology to homeland security, immigration control, and public security. Since 2009, our organization, the Ministry of the Interior, National Police Agency, has also been working on generating facial recognition technology and verification system. Until now, this initial work has already paid off and will bring massive benefits in the foreseen future to police organizations. These benefits include crime detection, order maintenance, people searching, and identification verifying. For practical applications in the future, it will cater more to front-line police officers' needs and expand the efficiency of maintaining public security by combining video surveillance systems interfacing with portable police devices via backstage cloud computing technology to provide quick and consistent verification result.
