Dr. Dobbs Portal (Journal) provides an article based on Googling Security: How Much Does Google Know About You? a book coming out later this month by Greg Conti. Conti is an Assistant Professor of Computer Science at the U.S. Military Academy (aka West Point). His premise in the article:
You face significant risks from both your use of these services and the content they contain. This article analyzes the information you disclose when using mapping and imagery services, including how your use of these tools discloses locations of your home, employer, family and friends, travel plans, and strategic intentions, and discusses how data mining can easily link seemingly disparate groups of people based on their interest in common locations. It also covers the risks inherent in the content itself, including camera-equipped cars capturing continuous streams of high-quality street-level photographs, collaborative analysis of satellite imagery, and your inability to trust the veracity of the images themselves.
Frankly, it raised a number of issues I'd not considered.
