he was increasingly worried about the way the web has been used to spread disinformation.
Sir Tim told BBC News that there needed to be new systems that would give websites a label for trustworthiness once they had been proved reliable sources.
I'd be interested in different organisations labelling websites in different ways".
Sir Tim spoke to the BBC to publicise the launch of his World Wide Web Foundation which aims to improve the web's accessibility.
Alongside this role it will aim to make it easier for people to get online.
The Web Foundation will also explore ways to make the web more mobile-phone friendly.
