Actor Registration (mini pattern)
Most I&A approaches involve identifying and authenticating an actor against a pre- viously-established known record. Determining how the known record is established is the function of actor registration. This pattern helps you to design a registration mechanism for an actor or user. The type of information recorded depends on the I&A mechanism used. For example, if you are using an ID and password mechanism, then you need to define a user account ID and establish a password. If you are using signature verification, you need to capture user signature samples. This pattern covers the more common types of I&A mechanisms, such as those identified in this book.
