Directing internet service providers (ISPs) to police the internet will put some firms out of business, one analyst predicts.
Mark Jackson, editor of ISPreview.co.uk, has said that urging ISPs to establish whether someone has downloaded information illegally would essentially turn companies into a security service.
"The ISP would need to log utterly unbelievable amounts of data and employ a team able to deal with and investigate such requests," he asserts.
This would result in some suppliers being forced to raise their subscription costs, while others could simply go out of business.
His comments come following a recent study that found that tens of billions of files were swapped illegally in 2007.
Furthermore, the Internet Service Providers' Association argues that broadband companies cannot be solely responsible for monitoring customer usage.
The association adds that under current law, ISPs are prohibited from analysing individual packets of data that are sent.
