RIG (Random Identity Generator) is a free replacement for a shareware program out there called ‘fake’. It generates random, yet real-looking, personal data. It is useful if you need to feed a name to a Web site, BBS, or real person, and are too lazy to think of one yourself. Also, if the Web site/BBS/person you are giving the information to tries to cross-check the city, state, zip, or area code, it will check out.
It is suitable for wesbites like NYtimes that asks for your personal information during registration, this will help you fend off junk mail or telemarketers if they decide to sell your information to third party. Also helpful for webforums if you want to stay anonymous.
