An international conference organised by the United Nations opens in Paris today Monday aimed at finding ways to prevent the Internet from being used to spread child pornography.

Experts and officials from forty countries will be trying to establish how nations can work together to track down those using the Internet to exchange pornographic material.

They will look at the creation of an international legal framework to deal with the problem.

Experts say those viewing child pornogoraphy on the Internet are not as anonymous as they think they are -- every visit leaves a record of their presence at the site and on their own computers.
