Google Child Abuse Image Block 'Not Enough'

Critics say the move to block tens of thousands of search terms that show depraved images and videos "simply masks the symptoms".

Naturally Downing Street officials are portraying this is a victory for David Cameron. The internet companies had seen reluctant to take actions to censor the content, but pressure from PMs has brought together two huge rivals: Google and Microsoft in their rare display unity.Well, if you build a wall, someone is gonna try and get over under or around. It's important we collaborate on such important issue.

We do take a lot effort to remove and report this content, but we do accept that there is more we can done. We are very happy to do that.

But immediately people are searching for evidence that would make any real difference.

Halting predicative text on searches might stop innocent being inadvertently let stray, so might warnings about your illegal behavior. But experts in child protection say it would not block determined pedofiles.

This is the beginning and not the end, and it's a small step forward not huge one when it comes to actual child protection. What we need to see now is Prime Minister's focus influence being used to help us to catch the predators.

Google says they have 200 staff developing new technology to identify and block child pornography, the rival Microsoft has already develop the ability to recognize illegal photographs and track them when they are copied and distributed. Now Google says they've been able to do the same with video.

The program allows analysts to break out every video to calculate unique digital signature. That signature is then matched again other version on line even if they've been edited and altered. Once they've been identified, all copies are then deleted from the Internet.

Steward Hazzles scoured the web for underage pornography before murdering Tiya Sharp.But most images shared by pedofiles are down someone close networks beyond the capacity of internet searching engines. That requires globe police action.

You can go after these pedofile to pedofile sharing, you can take down the size, you can prosecute these people, I want to see , you know, people being prosecuted for these violent crime. We are putting resources into the police into international crime agency ,working in all steps with Americans to make sure we go after these people.

Campaigners, like Sara Paine whose daughter Sara was killed by a sex offender, say there is only one way to really tackle the problem.

Mr. Cameron, please just fund police properly , so they can do this and get better of this.And be a force three reckoned with, so pedofiles do not hurt us anymore.

While warning can easily be ignored, tracking online predators to their homes is real challenge.
