Shokaster writes "The Register reports that Virgin Media are to begin monitoring file sharing using a deep packet inspection system, CView, provided by Deltica, a BAE subsidiary. The trial will cover about 40% of customers, although those involved will not be informed. CView's deep packet inspection is the same technology that powered Phorm's advertising system. Initially Virgin Media's implementation will focus on music sharing and will inspect packets to determine whether the content is licensed or unlicensed, based on data provided by the record industry. Virgin Media emphasised that records will not be kept on individual customers and that data on the level of copyright infringement will be aggregated and anonymised."
