Is it time for Web publishers and their users to have the privacy talk? At most Web sites, privacy policies are ridiculously long and convoluted scrolls of legalese that only a hearty privacy watchdog would read. For most users it remains a mystery just how publishers collect, use and share the data trails consumers leave behind while traversing a site. But publishers now are partnering more deeply with third party ad networks who plant their own cookies in their users' browsers and hit them again with ads out on their own networks with other publishers. How should a site broach the topic of privacy and ownership of data with its own customers? The industry-funded Future of Privacy Forum is hoping to get at this issue in a new research initiative that explores different ways sites can communicate with users about their online advertising experience and how a use's data trail is recorded and used. The study will try to find ways that publishers can raise user awareness about the use of online behavioral data and be more transparent about how it is harvested and shared.

Laws in Canada and other countries are increasingly helping technology force people to identify themselves where they never had to before, threatening privacy that allows people to function effectively in society, a new study has found. "What we're starting to see is a move toward making people more and more identifiable," University of Ottawa law professor Ian Kerr said Wednesday. His comments followed the launch of Lessons from the Identity Trail: Anonymity, Privacy and Identity in a Networked Society, a book summing up the study's findings, at a public reading in downtown Ottawa hosted jointly with the Privacy Commissioner of Canada. Kerr led the study with University of Ottawa criminology professor Valerie Steeves. They collaborated with 35 other researchers in Canada, the U.S., the U.K., the Netherlands and Italy. The researchers reported that governments are choosing laws that require people to identify themselves and are lowering judicial thresholds defining when identity information must be disclosed to law enforcement officials. That is allowing the wider use of new technologies capable of making people identifiable, including smartcards, security cameras, GPS, tracking cookies and DNA sequencing. Consequently, governments and corporations are able to do things like: * Embrace technologies such as radio frequency identification tags that can be used to track people and merchandise to analyze behaviour. * Boost video surveillance in public places. * Pressure companies such as internet service providers to collect and maintain records of identification information about their customers. While Canada, the U.K., the Netherlands and Italy all have national laws protecting privacy - that is, laws that allow citizens to control access to their personal data - such legal protection does not exist for anonymity, Kerr said. "Canada is quite similar [to other countries] with respect to anonymity. Namely, it's shrinking here just as it is there.

Bruce Schneier is the chief security technology officer at BT and a celebrated writer and speaker on privacy, cryptography and security issues. Welcome to the future, where everything about you is saved. A future where your actions are recorded, your movements are tracked, and your conversations are no longer ephemeral. A future brought to you not by some 1984-like dystopia, but by the natural tendencies of computers to produce data. Data is the pollution of the information age. It's a natural byproduct of every computer-mediated interaction. It stays around forever, unless it's disposed of. It is valuable when reused, but it must be done carefully. Otherwise, its after effects are toxic. And just as 100 years ago people ignored pollution in our rush to build the Industrial Age, today we're ignoring data in our rush to build the Information Age. Increasingly, you leave a trail of digital footprints throughout your day. Once you walked into a bookstore and bought a book with cash. Now you visit Amazon, and all of your browsing and purchases are recorded. You used to buy a train ticket with coins; now your electronic fare card is tied to your bank account. Your store affinity cards give you discounts; merchants use the data on them to reveal detailed purchasing patterns.

Bits readers have a serious case of broadband envy. I've been writing about the debate about how the government might encourage more high-speed Internet use and you've complained loudly that people in other countries have faster, cheaper, more widely available broadband service. Even customer-service representatives of Internet service providers overseas are nicer too. I don't know about manners, but it's easy to find examples that American's broadband is second-rate: In Japan, broadband service running at 150 megabits per second (Mbps) costs $60 a month. The fastest service available now in the United States is 50 Mbps at a price of $90 to $150 a month. In London, $9 a month buys 8 Mbps service. In New York, broadband starts at $20 per month, for 1 Mbps. In Iceland, 83 percent of the households are connected to broadband. In the United States, the adoption rate is 59 percent. There's more than just envy at stake here. President Obama campaigned on a promise of fast broadband service for all. On the White House Web site, he writes "America should lead the world in broadband penetration and Internet access." And the recent stimulus bill requires the Federal Communications Commission to create a national broadband plan in order to make high-speed Internet service both more available and more affordable. I've spent the last week trolling through reports and talking to people who study broadband deployment around the world to see what explains the faster and cheaper service in many countries. We'll start with where the United States isn't doing quite so badly: the basic speed of broadband service. If you take out the countries that have made significant investment in fiber optic networks - Japan, Korea and Sweden - the United States is in the middle of the pack when it comes to network speed.
