Prime Minister Gordon Brown urged parents today to be alert to the dangers to children of using computers following proposals for the internet and video games to come with cinema-style age classifications.
Psychologist Dr Tanya Byron said she is making "some pretty tough" recommendations to the Prime Minister as parents need help to tackle digital safety.
Dr Byron, who was commissioned by Mr Brown last year to report on fears that new electronic entertainment may be harming children's moral value systems, is also calling for a massive education campaign.
Mr Brown told GMTV: "If our children were leaving the house, or going to a swimming pool or going to play in the street, we would take all the care possible about their safety - is there proper policing, is there proper safety?.
"When a child goes on to the computer and on to the internet or on to a video game we should be thinking in the same way."
Parents and teachers, hampered by not having grown up in the computer age, need information in "a more simple form", according to Mr Brown.
At present, only games showing sex or gross violence require an age rating from the British Board of Film Classification and fewer than 2% carry an 18 certificate.
A new legally-binding system could ensure that every game is rated in the same way as films - classed U (universal), PG (parental guidance), 12, 15 or 18 - with the age guidance printed clearly and prominently on its sleeve in a way that can be understood by parents who are not computer-savvy.
Mr Brown said: "We've got to get the classification clearer... when someone is trying to sell a game, they've got to give the proper information.
"I think Britain can lead the world in this because other countries have got the same problems and all of us as parents are worried about our children, so let's see if we can make a difference in this."
Launching her six-month review alongside Schools Secretary Ed Balls and Culture Secretary Andy Burnham in London today, Dr Byron is expected to say that the internet and video games have a massive potential in terms of education and development.
Dr Byron, best known for her work as child behaviour guru on TV shows Little Angels and House Of Tiny Tearaways, will also warn that her report shows there is too little awareness of the dangers they may pose.
The report is expected to say that computers should be sited in family parts of the house, such as the living room, rather than in children's bedrooms. And it will suggest that parents should monitor their children's online activities to ensure they are not viewing inappropriate content.
While many parents regard internet use as being similar to watching television, Dr Byron will warn that it is more like being sent outside to play unsupervised.
Parents could be given guidance - or maybe even computer classes - to ensure they cannot be outwitted by children who have grown up with new technology and may be more skilled at using it. And the report will recommend the establishment of a UK Council for Child Internet Safety, reporting to the Prime Minister, with representation from Government, industry, children's charities, young people and parents.
The industry will be challenged to take greater responsibility by drawing up codes of practice for social networking sites such as Bebo and mySpace, introducing more effective regulation of online advertising, and improving access to parental control software.
Claude Knights, director of children's charity Kidscape, said: "This is about working together to educate parents about computer games and the internet.
"It's about being very open about the potential dangers. It's not about prohibition. If we build walls, young people will climb over them. There has been a 'mind the gap' situation, where parents feel disenfranchised. Parents and carers need more support.
"Video games and the internet can be bamboozling for parents. What we need is clarity, so that parents buying the products have a level of understanding about exactly what it is they are buying."
