1) Explain your own example of a way in which you are required to authenticate yourself to get access to a software service or resource. Is the authenticator "something you have" , "know", or something you "are"?

2) Next, briefly explain how file encryption is used, or could be used, effectively as part of the service or resource. For example, in using a web-based email service, are you required to authenticate before gaining access to the email account? Would file encryption be useful as part of this service? Why?
