Advertisers must let consumers skip online tracking
'People’s choices must be respected,' says Canada's privacy commissioner
Consumers should always be able to opt out of online tracking used by companies to provide them with targeted advertising, Canada's privacy commissioner said Tuesday.
Has a targeted ad ever made you feel uneasy? Take our survey.
Companies such as Google are increasingly tracking the behaviour of web users in order to make their ads more relevant to their interests.
Privacy Commissioner Jennifer Stoddart said her office recently learned that credit card company Visa has taken out patents to market its transaction information for targeted advertising by combining it with information from social networks, credit bureaus, search engines and online wish lists.
"Some people like receiving ads targeted to their specific interests. Others are extremely uncomfortable with the notion of their online activities being tracked. People’s choices must be respected," said Stoddart in a statement while releasing new guidelines on online behavioural advertising at the Marketing and Law conference in Toronto.
Targeted advertising on Google
When asked about the new guidelines and whether Google Canada was following them, the company provided a list of features that allow users to manage their privacy settings:
- Google Dashboard, which helps answer the question, 'What does Google know about me?' It shows what information is stored in your Google Account and enables you to change your privacy settings for many products in one central location.
- The Ads Preferences manager, which allows you to view and edit the information Google uses to show you personalized ads on its partners' websites. This is where you can add or remove an interest category associated with your web browser or opt out of seeing targeted ads altogether.
- Google has developed plug-in for its Chrome browser that allows users to save their opt-out preference permanently.
- Google Takeout and the company's Data Liberation Front initiative allow users to move their data in and out of Google products.
Stoddart said the use of technologies that track and target ads to certain consumers has risen dramatically.
"And we're concerned that Canadians' privacy rights aren't always being respected."
She cited a recent study by AT & T and Worcester Polytechnic Institute that documented how popular websites have automatically forwarded personal information to data tracking aggregators, apparently without meaningful consent of users.
"My office is very concerned about this issue and it's something we're examining closely."
Stoddart said the type of information used to track users and target ads could be used to identify someone and can therefore be considered personal information. As such, it is covered under Canadian privacy laws governing such information.
The new guidelines are intended to provide companies with guidance as to how they can comply with the law, she said in an interview.
"We're saying Canadians should be able to understand what personal information is being collected about them, they should be able to consent to it and collecting their personal information should not be a condition of service to a site."
Stoddart suggested that other kinds of advertising, based on non-personal information such as individual searches rather than online tracking, can also be used on sites that rely on ad revenue.
She added that her office will keep an eye out in coming months to see whether companies are complying with the guidelines: "If we see troubling trends, we will take enforcement action."
Currently, companies are not transparent enough about their use of behavioural advertising, she said.
The new guidelines say:
- Any collection or use of a person's web browsing activity must be done with the person's knowledge and consent.
- Internet users should be able to easily opt out, ideally before the information is collected.
- Technology that makes it impossible for the user to opt out should be avoided. Examples include zombie cookies, super cookies and device fingerprinting.
- Organizations should avoid tracking children and tracking on websites aimed at children because they cannot provide meaningful consent.
- The information collected should be limited and should never include sensitive information such as that related to health.
- The information or the link between the information and a person's identity should be destroyed as soon as possible.
Stoddart said her office is continuing its research on the use of online behavioural marketing, which is still developing. In fact, she said, in the coming weeks, it will release the results of a 1½-year investigation on a social networking site targeted at youth with many advertising and tracking features.
Meanwhile, the Interactive Advertising Bureau of Canada is working on a new icon in the shape of an "i" that consumers can look for on participating websites and click learn what information is being collected by the website.
While the privacy commissioner's guidelines are targeted at advertisers, Stoddart hopes they will also make internet users more aware so that they will look for information about online tracking and behavioural advertising on the websites of online services they use.
Other countries have also been working on rules and guidelines for online behavioural advertising. For example, the European Union requires internet users to opt in before tracking devices called cookies can be stored in their browser under most circumstances, she said. The U.S. Federal Trade Commission has also been looking into the issue.
