William Pulleyblank Quotations

You may discover patterns over time to find out what that person is up to.

There have been a lot of things done to secure data and identify people, like passwords, etc. But this is a new phenomenon, where somebody entitled to use the system begins to use it outside of the parameters. Say a person is entitled to look up social security numbers and do a credit check as part of mortgage application, then all of a sudden this person decides to run 500 people through in the after hours.

The solution is looking for patterns. It looks at a group to find out what it's doing and find out who's doing something different.
