Radarix.com, a self-styled private detective web site registered in the United States, claims to carry three terabytes of personal data on citizens of Russia and former Soviet republics.

Time was when getting your hands on an individual's income, property and telephone numbers required a trip to a nearby kiosk to buy pirated discs containing illegal databases.

But now one web site is offering a one-stop, online database providing extensive confidential information about Russian citizens to anyone with a computer and an Internet connection.

Radarix.com, a self-styled private detective web site registered in the United States, claims to carry three terabytes of personal data on citizens of Russia and former Soviet republics.

"Our area of activity is extensive. It does not stop with helping people search for their relatives and close friends, which by itself is invaluable," reads an e-mail sent to users who register with the site. "Only our system can help many people avoid the fate of victims of deception and criminal machinations."

The e-mail is signed by Serzh Kovalenko, identified as the development director for Radarix Group.

The site, which as recently as last week was providing individuals' home and cell phone numbers, license plate numbers and tax numbers, among other data, has sparked outrage among senior lawmakers and highlights the government's tenuous ability to keep citizens' private data from seeping into the public domain.

But at least two individuals were off-limits for web surfers: President Vladimir Putin and President-elect Dmitry Medvedev.
