About Quatro

The Quatro Project

The Quality Assurance and Content Description project (Quatro) aims to help internet users find what they want, trust what they find and avoid material that, for whatever reason, they choose not to see. This is achieved by highlighting websites that are recognised as meeting a variety of quality criteria set by one or more “Labelling Authorities.”

Quatro’s browser extension, ViQ, allows you to see whether the site you are on is labelled and, if so, whether that label has been authenticated by the labelling authority that issued it.

The LADI search tool delivers results from either the Yahoo! or Google search engines with annotations next to websites that are labelled. Again, you can quickly see whether the labels detected are authenticated by the relevant labelling authority.
