With my Xbox I got a two month trial subscription to Xbox Live, so I tried signing up. In the beginning of the sign up procedure you get this message (emphasis added by me):
Welcome to the future of gaming. You are about to subscribe to Xbox Live. Xbox Live uses security technology to help safeguard your information. If you have an Xbox Live subscription code and high-speed Internet service, please continue. Otherwise, see www.xbox.com/connect or a local Xbox retailer.
Wow! “security technology”. I'm so impressed.
