About Biometric Electronic Access ControlBiometrics, or the recognition of the identity of someone based on a biological aspect of a person, is actually a very old technology. We use biometrics everyday when we use the ?computer? that we call the human mind: for example, when we recognize someone by looking at his or her face, or when we check a written signature against what we trust to be a bona-fide copy of a signature. The futuristic feel of biometric technology comes about when we match the traditional biometric approach with the new capabilities that we have in electronics. Now we can use electronic devices to make biometric judgements about the authenticity of a person?that is, ?is person x who they say they are?? Since the information and digital age is upon us, the technology has come about that makes authentication exceptionally accurate, and potentially a much more reliable means of authenticating a pers free guitar lessons on than traditional, human-judgement based biometrics.Experts in authentication technologies usually classify the criteria that are used to verify someone?s identity based upon a few different categories. ?What you know?, or W-Y-K, is one form of authentication: a common version of this occurs when you give an electronic bank terminal your PIN (or Personal identification number). ?What you have?, or W-Y-H, is another criterion, and this refers to the possession of some identifying object such as an identification card or passport: but you could even consider a simple door key as a kind of W-Y-H proof of identity for allowing access into a private or controlled access property. Biometrics, according to this scheme of classification, would generally be termed ?What you are? or W-Y-A. It is the presentation of a physical aspect of yourself that is quite uniquely and individually you, in order to obtain authentication.
