摘要：This article introduces biometrics and discusses some of the complex issues associated with use of biometrics for identification and authentication of individuals and its impact on both standalone and networked information systems, as well as on physical security. The agenda is not to show whether biometrics is your best investmentor a useless thing—these two polar viewpoints share the same quality of being over simplifications, to say the least. It also certainly does not purport or try to tell everything there is to tell about biometrics or its applications. Legal and social implications of biometrics are also not discussed in this article because these would differ considerably, depending on the legislation and cultural traditions of countries concerned; we also do not consider the complex performance, design, and implementation questions, because these are of too specialized nature—for more in-depth coverage of these topics a list of biometrics organizations and publications are provided at the end of this article, along with a list of references.
