BT has restarted its Phorm trial despite huge privacy concerns.
The Phorm system allows BT to track and monitor every website that a user visits. BT puts this information into a database and is then able to insert its own advertising onto web pages that is targeted specific to those users. The system has caused an outrage amongst privacy advocates and the City of London police recently cleared BT of any wrongdoing in its secret trials.
The latest experiment which was delayed due to privacy concerns will affect up to 10,000 users over a 4 week period.
The WebWise system that Phorm has built could have access to details of every website that customers visit, as well as every internet search they conduct and other personal information.
It's rumored that Phorm is in talks with other UK broadband ISPs, including Virgin Media and TalkTalk.
