This sounds like nothing but a glorified keystroke sniffer like xkey. More importantly, however, if my system did get compromised, I would have bigger worries than my credit card number. I give my credit card number out to people every day, but no one knows my PGP or ssh passphrases, for example. You may argue that many people don't have source code to their OS's, so that viruses can spread more easily to them than to me. Well, many people don't do backups, either. Ask most people if they would rather divulge their credit card numbers or loose the entire contents of their hard drives, and I think the answer will most likely be the credit card number disclosure. This article looks like a cheap attention getting device for FV to get some free publicity. I am not impressed. David
