When do the new UK porn laws come into effect?
Porn website visitors will have to prove they are over 18 to access adult content, the Government has announced.
Users will have to provide credit card details to get on the site in a bid to protect children from porn content.
Websites flouting the new rules, set to be part of the Digital Economy Act, could find a regulator has told their internet service providers to block access to them.
The aim is for all online porn to have age verification by April 2018.
But child safety campaigners warned the age checks don’t go far enough.
An NSPCC spokesman said: “Robust age verification and regulation for online pornography are important first steps in keeping children safe online. But these steps do not go far enough.
“The NSPCC is calling for social networks to be required by law to give under-18s safe accounts with extra protections built in, so that children are kept as safe online as they are in the real world.”
How will the ID age check for online pornography sites work?
Ministers laid out plans to make porn providers install age verification software on their adult sites similar to gambling sites.
Under new powers, regulators will be able to block porn websites if they fail to show that they are denying access to under-18s.
They will be required to demand credit card details or proof of age and face fines of up to £250,000 or being blocked by UK internet service providers.
Digital economy minister Matt Hancock said it would mean the UK having the “most robust internet child protection measures of any country in the world”.
The regulator – expected to be the British Board of Film Classification – will be required to ensure that methods are “robust” and go beyond simply ticking a box or typing in a date of birth to say that the user is over-18.
It is thought that initially credit card data will be used, but other methods will be adopted as technology develops, possibly including links to the electoral register.
Adult sites based anywhere in the world will be required to show that they are verifying users’ age.
It will be overseen by a new regulatory body, the Department for Digital, Culture, Media and Sport said.
