Concerns about the security of Internet messages were no longer valid, the founder of the World Wide Web, Mr Tim Berners-Lee, said this week.

Speaking in Australia, Mr Berners-Lee said security on the Internet was now more of a problem for governments because cryptography was so strong that "it's impossible for somebody else to find out what you're saying".

He also criticised attempts at Web censorship, saying Web technology tries not to enforce a particular policy or view on its users. "I believe if somebody is going to decide what a child should see, then it's a good idea for that person to be a parent," he said.
