In the government's second major effort to keep Internet pornography away from children, the House will consider a bill requiring companies to restrict access by youngsters to "harmful" online material.

The Child Online Protection Act would require commercial Web sites to collect a person's credit-card number, for example, or some adult access code given upon proof of age before allowing viewing of photographs or other material considered "harmful to minors."The House Commerce Committee unanimously approved the legislation Thursday on a voice vote. A companion bill by Sen. Dan Coats, R-Ind., earlier passed the Senate Commerce Committee. Even some critics acknowledge that Congress is likely to pass one version by the end of the year.

Critics complained the bill defies the spirit of the 1997 decision, which held that the Internet is entitled to "the highest protection from governmental intrusion."
