Ramifications
Lots of information readily available
Can find out some troops’ locations overseas
Easy to find a person’s home
How much is available about you?
![Page 19: The Internet Hunt Revisited](https://reader036.vdocuments.us/reader036/viewer/2022071603/613d7aa4736caf36b75dd02c/html5/thumbnails/19.jpg)

If we were bad...
We could attempt masquerading as an individual
Obtain birth certificates, credit records, marriage licenses
Bribe the person
Find troops’ locations
Coerce information from them (masquerade as another)
Google for Credit Card Info[3]

Conclusion
Lots of Information available
More content, less reliable
Best sources were Intellius and the subjects themselves
General searching may spawn more information
Identity theft risk
Advanced technology brings about different privacy concerns
