The Obama administration, according to The Wall Street Journal, is expected to announce to Congress today an internet privacy bill that will force some data miners to make major changes. Sen. John McCain (R, Ariz.) was a critical opponent of net neutrality, but he was actually a sponsor of the draft of the privacy bill, along with a fellow Presidential runner-up, Sen. John Kerry (D, Mass.).
The bill looks to expand the powers of the U.S. Federal Trade Commission, giving it the ability to enforce the new provisions. The proposal follows a December U.S. Department of Commerce report [PDF], which complained that Facebook, Google, and a host of smaller firms weren't up front with customers about what information they were collecting and sharing with advertisers.
Dubbed an online "Privacy Bill of Rights", the measure would prevent information from being used for any purpose other than collected, unless you give them permission. In other words, if you fill out a registration form for the website, they will no longer legally be able to sell that information to advertisers, unless they ask you if it's okay.
