Alert system will remove millions of child porn images

Technology is tightening the net on people who create and share illegal images of child abuse.

International law enforcement is being given key information, which will allow them to arrest perpetrators and rescue victims.

Internet giants, such as Facebook, Google and Twitter, have been given access to a British database. This will enable them to uncover and remove millions of the online images, thanks to a system that catalogues the pictures with ‘hashes’.
