I am rather new to the programming world and my main area I concentrate in is databases. Now my dilemma is that I want to start a new project that is way out of my league and I need someone to help direct my thoughts.

I want to try an ID system where I have images of employees in my company and then when they sit in front of a PC have cam get an image of them and then compare it with the database allowing me to identify them. I want to use this more as a utility than a security system though.

My thoughts were to compare a bitmap color count and then match that. Would that work?
Has anyone attempted something similar?

Ciao
