Even as California is introducing their Do Not Track bill to stop the unwanted tracking of internet users, a similar bill is being introduced on Capitol Hill. The bill would allow internet users to opt out of the collection of their personal data. It is the fourth such bill to take a stance on online privacy.

The bill was introduced on Monday by Senator Jay Rockefeller. The Do Not Track bill requires companies to collect information only on those who do not opt out of the tracking. Necessary information for providing services could be collected but are required to be either anonymized or deleted altogether immediately after the service is completed.

Three other bills that directly address internet privacy have been introduced. At this time, it’s too early to know which one, if any of them, will actually make it into law.

Senator Rockefeller is the chairman of the Senate Committee of Commerce, Science, and Transportation. After the recent episodes with Apple iPhones collecting location data and the recent breach of Sony’s PlayStation Network, online privacy has become a central issue. In a statement, Senator Rockefeller said that he believes users have the right to decide if their information can be collected and used online.
