The Internet gives us information, communication options, shopping opportunities, entertainment, and much more--all at the touch of a fingertip and much of it for free. But in exchange for these benefits, we may be losing a basic right: the right to privacy. By clicking to accept website user agreements, we often allow companies to track our activities online and to share our data with outside groups. In addition, the police and government agencies can also track people online--and this tracking is sometimes done secretly, without user agreements or search warrants. Privacy laws and the US Constitution are supposed to protect privacy in the United States, as are laws and conventions in other parts of the world. But judicial and legal systems have not kept pace with technology. And until laws catch up, users enter a legal gray area when they communicate digitally--an arena in which their most private conversations might not be protected from intrusion."--Amazon.com.
