the Above petition is about this

We petition the Prime Minister to investigate the Phorm technology and if found to breach UK or European privacy laws then ban all ISP's from adopting it's use. Additionally the privacy laws should be reviewed to cover any future technologies such as Phorm

The UK's three largest ISP's, Virgin Media, BT and TalkTalk are all in talks with a view to introducing the Phorm technology. This would result in the browsing habits of the majority of the UK population being sold to a third party for advertising purposes. The opt out system for this technology is vague and unproven, even when opting out your every move on the Internet might be recorded. Surely this must be a breach of privacy laws, if not then the privacy laws need to be changed to cover such invasive technology.

if the above doesn't make a lot of sense basically Phorm will supply your ISP a box that collects info on the Web pages/services you use then it will add Adverts to web pages based on your previous web use they all claim that no personnel information will be held on file but to make something personnel to you they have to have some personnel info even if this is just your IP address, the only thing that will come out of this is more companies will have access to your surfing habits(they know what you do ) thye also claim that you can opt out however all opting out does is stops your ISP sending your info to Phorm it will still be collected by your ISP will still be able to collect this info, on top of signing this petition you need to contact your ISP and tell them you don't want this or anything like it
if you want to know more simply type PHORM into your search engine
