There are a couple of exceptions to that: ߜ At a very basic level, most biometric systems are required to authenticate a user and then grant access to that user based on the successful authentication. The “granting access” part of that process can be performed by other systems, based on information that the biometric system supplies (saying, in effect, Yup, that really is Rhonda). ߜ In some cases the biometric system itself may directly grant access based on a successful authentication.

The user provides other information such as her user ID or name, and then provides initial biometric data, which could consist of (for example) swiping fingers over a fingerprint reader (for fingerprint biometrics), looking into a digital camera lens (for iris biometrics), or repeating some words or phrases (for voice biometrics). Usually the biometric system will request several samples so that the system can determine an average and deviation. 13 14 Part I: Getting Started with Biometrics 2. Usage.

13 14 Part I: Getting Started with Biometrics 2. Usage. When the user wishes to access a system or building guarded with biometrics, the user authenticates according to procedure, which could mean swiping a finger over a biometric fingerprint reader, placing a hand over a hand scanner, or signing his name. However it’s done, the biometric system will compare the sample with data stored at enrollment time, and make a go/no-go decision on whether the biometric data matches or not. If there is a match, the user is given access; if not, he is denied access and given another try.
