For starters, why don't you just try subtracting the images? You can get fancier by trying to find the faces in the image and then further narrow down the ROI to only where the eyes and lips are.

sir i hav some how managed to detect the face,,,now i hav a new problem that is while comparing two image by subtract is taking even a lighting change as difference.... so can plz suggest me any technique to avoid this problem while comparing the image...

Yes, that's right. It can be a very complicated problem. Check out how other people have done it here: http://iris.usc.edu/Vision-Notes/bibliography/contentspeople.html#Face%20Recognition,%20Detection,%20Tracking,%20Gesture%20Recognition,%20Fingerprints,%20Biometrics
