Privacy concerns have been raised again as yet another search engine is set to hit the Internet, this time with information on all the people in the world. 

Spock.com hopes to be able to track down all of the world's 6-billion people, and at least provide a search result for everyone.
The company, which has been developing the site for over a year, already has 100-million people on the beta version of the site.
It is also adding about 1-million names a day on the invitation-only beta.
The site will go public later this month.
