Here's one possibility. Implemented as an instance of a class Info, for example, information will know everything about itself. An object of the ComputerUser class will reside on my machine. Authentication and protection will be built into the ComputerUser class. Object oriented technology stresses specifying first what an object is, then how is it used.
Implementation is the very last thing.
At this point, I am absolutely unconcerned how the classes will be implemented.
