Rkhunter does this technically. It takes the SHA-1 sum of files and matches them to known good ones in an online database. You could possibly make it list all of the files on the system and compare them to a local database.

Only difference is, my application doesn't scan for rootkits. It scans for change. It also used MD5 instead of SHA-1 sums. It builds a local database of your computer. Than it scans those hashes each day - hour. When change is detected, it gets added to a list. In that way you have an overlook of what files have changed with or without the user knowing. That is what my application is meant for. So I understand what you mean, but it's not really the same.
