Both Google and Microsoft are taking part in the new initiative with internet search results being the first thing affected.
The companies focused on over 100,000 search terms commonly used by those looking for images of child porn or abuse.
Those terms will now result in an on-screen warning instead of photos.
Google’s Eric Schmidt told The Daily Mail they have "put more than 200 people to work developing new, state-of-the-art technology to tackle the problem."
He continued “we've fine-tuned Google search to prevent links to child sexual abuse material from appearing in our results."
They began with the English-language but Google confirmed very quickly “more than 150 other languages” will be added.
YouTube has been on the wagon for quite some time having developed technology that can detect child porn videos. The company has been quick to share that system with anyone fighting the huge problem of child porn.
All of this comes just days after the worldwide arrests of nearly 350 people in a giant child sex abuse sting.
