The Obama administration plans to ask Congress Wednesday to pass a “privacy bill of rights” to protect Americans from intrusive data gathering, amid growing concern about the tracking and targeting of Internet users.

Lawrence E. Strickling, an assistant secretary of commerce, is expected to call for the legislation at a hearing of the Senate Commerce Committee, said a person familiar with the matter.

This person said the administration will back a law that follows the outlines of a report issued by the Commerce Department in December. The administration wants any new rules to be enforceable and will look to expand the Federal Trade Commission’s authority, this person said.

Among other things, the December report suggested that companies should ask an individual’s permission to use personal data for a purpose other than for which it was collected. The administration also eventually could propose that consumers be given the right to access information about themselves and to have the information stored securely, the person said.
