生物特徵包含指紋辨識、掌紋、虹膜、DNA、臉型辨識等。是與生俱來，擁有獨一無二的特性。近年來生物辨識科技發展愈發成熟，在日常生活中運用範圍日益多元，其中又以指紋辨識運用更為廣泛，從手機開機解鎖、筆記型電腦身份登錄、門禁系統管制、隨身碟資料加密等，皆大量使用指紋辨識來做為身份辨識的應用，但指紋辨識一方面為生活上帶來便利，另一方面也為個人資訊的隱私權帶來威脅。
　　本文是以科技接受模型（TAM）為研究架構，加入隱私權及信任與安全性兩個構面來討論一般民眾對於指紋辨識應用於身份辨識的使用意願並分析各項可能影響的因素。透過隨機抽樣方式進行網路問卷調查，對象包含不同年齡層、職業、收入、教育程度、工作年資，計得204份。
　　經偏最小平方法(Partial least squares, PLS)分析受測者對指紋辨識的接受程度。結果顯示，影響指紋辨識應用於身份辨識的使用意願的四項因素裡(認知易用性、認知有用性、隱私權及信任與安全性)，其中影響因素最大的是認知易用性，正向且顯著，也就是說，指紋辨識做為身份辨識這項服務，越容易使用及操作，將越受大眾歡迎，有趣的是，隱私權因素並無顯著影響，表示一般民眾對於指紋辨識的安全機制是放心的，不會擔心使用會有個人資訊外洩或資訊安全性的問題。

In recent years, with the development of biometric technology, biometrics is that people are born with unique characteristics, including fingerprints, palm prints, iris, DNA ... and so on. The usage in daily life is widely adopted for fingerprint identification, such as the logging in to switch on cell phones, and laptops, accessing door control system, flash data storage encryption, etc. These are cases of applying fingerprint identification for identity. Fingerprint can make life more convenient, on the other hand it also brings the threat to individual privacy.
The research structure of this study is adapted from the Technology Acceptance Model (TAM) with the inclusion of privacy and trust factors to investigate the acceptance of the fingerprint identification by general. We design a questionnaire surveyed across various age, occupations, and income groups which resulted in 204 valid samples.
Partial least squares modeling was applied to analyze the data regarding the acceptance of fingerprint identification. The results were mainly about the four factors (perceived ease of use, perceived usefulness, privacy and trust) which may impact the willingness of people to use fingerprint identification for identity. The biggest factor was the perceived ease of use which was positive and significant in triggering the attitude toward the acceptance. That implies that the easier of use and operation of the identification system the better of its acceptance. Interestingly, the right of privacy did not significantly affect the attitude, which may imply that the general public is assured with the security of the fingerprint identification. In other word, they are not worry about the leakage of personal as well as the IT security issues.
