Google executives have said the search giant will block searches for child pornography.

In addition, the company says they have been reporting to authorities anyone they find who has been posting pictures of child sexual abuse to the web. The evidence handed over by Google has been used in multiple convictions of abusers.

The changes to Google’s search algorithm are also being applied to 150 different languages in an attempt to combat the sharing of child pornography worldwide. The company is also putting warnings at the top of pages where people search for illegal images that the images violate international law and advice on where to seek help.

Engineers at YouTube are also working on a system that will automatically identify videos with children being abused so they can be immediately flagged by the search engine.

In addition, Google is funding internships at both the Internet Watch Foundation and the US National Center for Missing and Exploited Children to help those groups track down child abusers.
