The head of the Child Exploitation & Online Protection Centre has backed David Cameron's drive for computers to carry an automatic block to stop internet searches for pornography.
But Padraig Reidy, of the Index on Censorship, said the family-friendly filters will be too restrictive.
Child protection expert Mark Williams-Thomas has told Daybreak the Prime Minister is "confused" in attempting to link internet searches with how paedophiles access and share child abuse online.
David Cameron has told BBC Radio 4's Woman's Hour the Government is in a "row" with internet companies over a "blacklist of horrific terms" that paedophiles supposedly use to search for child abuse online.
Tia Sharp's grandmother has told Daybreak the Government's push for a crackdown on internet searches will not help stop child abuse.
Christine Bicknell was speaking after the Prime Minister met members of the Sharp family to discuss measures to block illegal content.
Ms Bicknell told the programme seeing images of child abuse online "fed" a habit in paedophiles but was not the cause of them acting out abuse.
She also said was "totally unaware" that her former partner Stuart Hazell, Tia's killer, was accessing depraved images on the internet.
David Cameron is set to announce a host of new measures to curtail abuse and unsuitable material on the internet.
The measures include:
- Possessing online pornography depicting rape will be illegal in England and Wales (it is already illegal in Scotland)
- Search engines are to be given until October to introduce further measures to block illegal content and block key words
- The Child Exploitation and Online Protection Centre (Ceop) will be given enhanced powers to examine file-sharing networks
- A secure database of banned child porn images gathered by police across the country will be compiled to trace illegal content and those viewing it
- 'Family-friendly filters' will be automatically selected for all new internet customers, they will have to request for them to be turmed off
- Existing users will be contacted by their internet providers and to decide whether to activate the filters
The Prime Minister will acknowledge the issue of extreme and child pornography is "hard for our society to confront" and "difficult for politicians to talk about" in a speech later today.
Possessing violent pornography containing simulated rape scenes will be made a crime in England and Wales, the Prime Minister is set to announce.
David Cameron will also set out plans for new laws so that videos streamed online in the UK are subject to the same restrictions as those sold in shops.
In a move called for by women's groups, ministers will close a loophole which allows the possession of "rape" porn, bringing the position in England and Wales in line with that in Scotland.
However some of his plans to ban certain search terms have already led to criticism for a lack of understanding of how abuse images are shared online.
The Prime Minister has warned internet companies could face tough new laws if they do not do more to stop images of child sexual abuse appearing online.
Mr Cameron said he is concerned about the problem as both a politician and a parent, and plans to give a major speech on the issue tomorrow.
