I'm looking for a program that will prevent certain keywords/numbers from being transmitted to websites (preferably websites I can define in the options, along with a white list for exempt websites if possible) by detecting when such info is typed by the user, and perhaps displaying an alert to the typist that they are entering sensitive info and to consult someone for help. I've searched for a while now and I'm not quite sure how to "word" my search criteria. I keep finding KeyLoggers, which are quite useless because they can only alert me after the fact.
Does this kind of software exist, and if so, can you recommend any for me?
I'm using Windows XP Pro SP2, and I use both FireFox and Internet Explorer, if that matters.
Cheers!
