Thousands of BT broadband customers are to have their internet usage tracked so they can be sent targeted online advertising in a final trial before the service is launched network-wide.
BT customers will be invited to take part in the trial of Phorm’s controversial advertising system Webwise from tomorrow.
BT and Phorm said in a statement: “Following successful completion of this trial and an appropriate period of analysis and planning, it is currently expected that Phorm’s platform will be rolled out across BT’s network.”
The trial was due to begin in March but has been delayed by technical problems and legal controversy.
Up to 10,000 BT customers will have their internet use monitored and categorised under the new trial.
Phorm’s online targeting service is designed to make advertising more relevant by taking account of all the websites a person visits, rather than just the content of a single web page.
Webwise works by having equipment at internet servive providers such as BT that will capture, for each site you visit, the URL, any search terms entered in a search engine, and other data from the page, in order to categorise it.
When users sign up for the system their browsers are tagged with a cookie - a small program with a unique code number used to identify each user. This provides the data used to create a profile of the type of websites each user visits.
When people visit a page where the advertising is sourced from the Open Internet Exchange set up by Phorm, they will see adverts targeted to their profiles. For example, someone who has visited a lot of travel-themed websites would see adverts for holidays, hotels and flights.
Categories of advertising campaigns that Webwise will not allow include tobacco, drugs, alcohol, pronography, gambling and UK political parties.
On its web pages about the new service, BT highlights how the new system will improve the user’s internet security by checking against a list of fraudulent websites.
Customers can decline to enter the trial, and will not see the invitation again unless they delete the cookie from their browser, for example as part of routine browser maintenance recommended for secure and efficient performance. BT admits under a heading “Isn’t that a pain in the neck?” that the only to decline the invitation permanently is to “set all your browsers to block cookies from the domain webwise.net".
Phorm has fought off concerns from privacy experts that Webwise is too intrusive.
In April the Information Commissioner said that Webwise did not represent a threat to privacy, but concerns from consumers have persisted. The Foundation for Information Policy Research, a group of Cambridge academics, has criticised the platform, saying that it infringed users’ privacy.
BT has admitted that it carried out secret trials of the Phorm technology in late 2006.
The Information Commissioner’s Office said that the service did not infringe an ISP customer’s privacy, because it did not collect information that would allow them to be identified. The system will also give users the opportunity to opt out of individual tracking, meaning that it does not breach the principles of the Data Protection Act, the commissioner’s office said.
Several websites have sprung up urging consuemrs not to use any ISP that introduces Webwise.
BT says on its Webwise site: “No personally-identifiably user data is stored as part of Webwise. Only the links between a random unidentifiable number contained in a cookie and advertising categories are stored in the system.
“This information is deleted after a maximum of six months. It is simply not possible to reverse engineer user identity using this information.”
ISPs hope that Phorm’s technology will enable them to increase their share of the burgeoning online advertising market. Analysts have predicted that BT’s cut from the online advertising could be as much as £85 million a year.
Advertisers are also said to be enthusiastic, because it will give them the chance to tailor their marketing more closely.

@ Paul Sullivan: You're wrong sir. "To be Phorm free you [DO] have to change ISP", and there has been NO legal fight yet - NONE. I have left BT this week 'cos even if one opts out, one's data DOES pass through the system. Given the recent data leaks on BT forums I am not risking staying with BT.

Hope it's a while before webwise is introduced otherwise the half dozen anti-phorm loons who blight the internet with their semi-literate ramblings will have to get a proper job.
And who'd employ that lot??
Tinfoil hat anyone?
Ima Littleteapot, Bedford,
BT should loose customers, and I say that purely based on their customer service, before they bring in this ridiculous web tracking, shame they dont spend their money on training staff and providing a decent service instead of the shambolic service I currently receive ! Time for BT to go down...
Chris, Manchester, UK
i don't know what pronography is but i like the sound of it.
james, falmouth,
This could be the worst time for BT to start this, they will lose customers. Also with the stock exchange crashing, fuel, food etc all going up people have less money than 12 months ago. Buying from websites that are paying more to advertise would mean you have less to spend.

Since nobody outside phorm/webwise knows exactly how the system works, people are only guessing and putting their own "spin" on things.
As for controversy, I think at the last count about 6 people actually contributed to the "outrage" including, if I'm right, Mr Mainwaring who has posted here twice.

"When users sign up for the system their browsers are tagged with a cookie - a small program ..."
No it's not, a cookie is just a bit of text.
Some commenters are suggesting deleting Phorm's cookies. That will not work, you need to accept their cookie in order to opt out.

legalised spyware! Just another example of how this country is obsessed with keeping tracks on the population.
Dave, Hebden Bridge,
Block cookies from www.webwise.net in your browser, and keep Phorm off your PC.

Just found this article with some tips on what to do about Phorm - it might be helpful?

Paul - the EU has not changed anything (yet). The ICO and BERR have said the system has to be opt-in.
The problem of a user not opting in is still real though. Even if a BT customer does not opt in his data is still copied and processed and thus his / her personal information is infringed.
Stephen Mainwaring, Weston super Mare,
Phorm is utterly pointless commercially unless BT choose to charge advertisers more for said 'targeted advertising' something advertisers can already achieve through ad servers like Doubleclick, Mediaplex and Atlas. BT are being conned basically or they are about to con advertisers more money.
David Walsh, Shrewsbury, UK
Stephen:
"To be Phorm free you have to change ISP"
Not true - BT (after a EU legal fight) has had to make form 'opt in'. Should it fail to adhere the legal bill will out weigh the benefit.
However if you are still paranoid look at Tor. This encrypts your data to SSL BEFORE reaching the ISP +free.
Paul Sullivan, Chester, UK
were are our right to privacy going?!?!
Im sure that will fall under the information t are already gathering about usage.
Think the goverment will not only see what sites you go on but read all about it too!
dave, leicester, uk
I've cancelled my £450 a year package as a result of this intrusiveness.
I think a lot more will follow and that £85 Million won't look as good.
John, Sheffield,
DavidE. Adblock will not help you one bit here. Even if you could block the ads your data will still be intercepted and processed.
Not only what you read on a web page, but in some cases what you type such as the message you typed here.
To be Phorm free you have to change ISP. It's the only way.
Stephen Mainwaring, Weston super Mare,
Well seeing as I block 99% of adverts on sites I visit they are wasting their time.
I use Adblock plus and NO script and haven't seen an ad for ages
And is it a coincidence that two of the most heavily advertised Building societies have just gone bust

David E, Reading,
Phorm is just wrong.
It is no different than someone listening to all your telephone calls so they can better guess which leaflets and menus to push through your letterbox.
People should be outraged about this.
Luke, London, UK
Well then, seeing as though advertising is a seriously massive business and BT users and soon others may have no choice about their surfing being tracked and targetted, surely Internet access should be free under these terms.
Internet service providers will become Customer Opportunity Providers.
Peter, Peterborough, Britain
If my ISP decided to do this, I would move to one that doesn't. I think this is going to prove to be a bad business decision by BT.
Unfortunately it is not so easy to move country, otherwise i would do based on what is happening with finger-printing/iris scanning at Terminal 5 etc...
Sam, London,
This is a system you should *not* have to opt out of, but opt in. Further loss of privacy, and not long before this data will begin to be used against us.
Lets home that the profit made from this will be overruled by the loss of business from every forward thinking internet user out there.
