The Cyber Intelligence Sharing and Protection Act ( ) was introduced last November and is scheduled for a vote in the U.S. House of Representatives next week.

The Electronic Frontier Foundation (EFF), the Center for Democracy and Technology (CDT), the American Civil Liberties Union (ACLU), Fight for the Future and other groups say that the legislation would allow Internet companies and the government to collect virtually any private online user content under the pretext of cybersecurity.

The privacy groups contend that CISPA would dismantle existing protections provided by the Federal Wiretap Act and the Electronic Communications Privacy Act and other laws.

They are hoping to stop the bill, or force amendments to it, by rallying widespread Internet opposition. Leaders say the groups will jointly call on supporters to contact local lawmakers to express their opposition.

The groups have also launched a Twitter campaign that aims to show lawmakers what kind of data the government could access if the bill is passed.
