A prominent online rights group has urged US lawmakers to scrap a proposal that would see all internet providers required by federal law to store information on their customers.

The Electronic Privacy Information Center (EPIC) appealed before a House Judiciary Committee hearing this week, asking that Congress recognize the fact that retaining identifying information would put at risk “99.9% of Internet users.”

The legislation in question is H.R. 1981, a bill to address concerns about children pornography. EPIC is concerned, however, over provisions within the bill that will require Internet Service Providers to store temporarily assigned IP addresses for future government use.
