Google and Microsoft unveiled measures to block online searches for
child sex abuse images on Monday as part of a bid by British authorities
to crackdown on Internet pedophiles.
The companies said as many
as 100,000 search terms will now fail to produce results and trigger
warnings that child abuse imagery is illegal while offering advice on
where to get help.
The world's two largest search engine
operators' move was a rare display of unity ahead of an Internet safety
summit on Monday hosted by Prime Minister David Cameron.
Cameron welcomed the progress to block illegal content but said far more still needed to be done.
"If
more isn't done to stop illegal child abuse content being found, we
will do what is necessary to protect our children," he tweeted ahead of
the summit that will announce a new trans-Atlantic task force to tackle
online child abuse. The summit comes after Cameron this summer called on Internet firms to do more to stop access to illegal images. Now both companies have introduced new algorithms that will prevent searches for child abuse imagery.
Google
executive chairman Eric Schmidt wrote in Britain's Daily Mail newspaper
that these changes had cleaned up the results for over 100,000 queries
that might be related to the sexual abuse of children.
"As
important, we will soon roll out these changes in more than 150
languages, so the impact will be truly global," he wrote, adding the
restrictions would be launched in Britain first then expanded to other
languages in the next six months.
Both Google and Microsoft, who
were due to join other Internet companies at the summit on Monday, have
also agreed to use their technological expertise to help in the
identification of abuse images.
Schmidt said Google planned to
provide engineers to give technical support to the Internet Watch
Foundation in Britain and the U.S. National Center for Missing and
Exploited Children, and to fund internships for engineers at these
organizations.
Conservative parliamentarian Claire Perry, who is
Cameron's adviser on childhood, said British and U.S. law enforcement
agencies would back up this effort by tracking pedophiles using the
"hidden Internet" or so-called "dark web" of encrypted networks to
distribute images of child abuse.
