This paper discusses spy ware and computer surveillance techniques. SpyWare also known as "adware" is a hidden software program that transmits user information via the Internet to advertiser in exchange for free downloaded software. Forget surveillance cameras, now your every action online could be being recorded without your explicit consent. This practice must be brought out into the open, so that you have a choice before giving out highly personal information. That's what this issue is primarily about choice and awareness. It has been confirmed that software companies who denied their software was even able to forward personally identifying information were not telling the truth. Using combinations of Machine and MAC address codes you can be tracked.
