Consent to Cookies? Who Wouldn't?

If the European Commission has anything to say about it, starting about 18 months from now companies will have to start obtaining consent from Web site visitors to place cookies on their computers.

Last week, the European Parliament approved amendments to Europe’s e-Privacy Directive (see page 76, item 5) requiring, among other things, that operators of Web sites obtain a user’s consent before placing a cookie on the user’s computer.  “Cookies” are digital files that are routinely placed on a user’s computer when they visit a Web site.  These files are used for many purposes, including to save a user’s name and password so they can be pre-populated in a Web site’s log-in page; to enable Web sites to engage in behavioral marketing by displaying ads that are keyed to a user’s browsing history; to enable Web sites to perform analyses of the demographics of the site’s visitors and what areas of the site are most popular; and to save the contents of a user’s online shopping cart.

Under the amended e-Privacy Directive, Web sites may only place cookies if the user has consented, after having been provided with clear and comprehensive information about the purpose of the cookie.  The amended directive provides an exception to the consent requirement if the cookie is “strictly necessary” in order for the Web site to provide a service specifically requested by the user.  While this exception is mildly helpful, it would not apply to most uses of cookies.

A recital (see recital 66) that prefaces the directive suggests that “where it is technically possible and effective,” consent may be expressed by using the appropriate settings of a Web browser or other application.  However, it is unclear whether user consent can be obtained this way when the default Web browser setting is to accept cookies, as is the case with most Web browser software on the market. 

Furthermore, due to the European law’s definition of “personal information,” the EU’s new rule even applies to cookies that do not collect a user’s name or contact information, on the grounds that anonymous cookies still enable a Web site to recognize a user who has been to the site before.

While this amendment leaves European companies in a state of alarm, it also leaves non-EU companies in a state of quandary.  The EU (specifically, the Article 29 Working Party) consistently has taken the position that its personal data directive (an older sibling of the e-Privacy Directive) applies to wholly non-EU Web sites that place cookies on computers which are located in Europe.  If the e-Privacy Directive also applies to all Web sites that drop cookies, the global impact of these amendments essentially requires every Web site to change its practices in about 18 months, which is the deadline by which European Member States must implement the e-Privacy Directive’s amendments.

Flash Cookies -- Back on the Radar

 

When Flash cookies (also known as a “Local Shared Objects”) were first flagged as a privacy issue back in 2005, a few savvy companies added a disclosure about Flash cookies into their web site privacy policies. Since then, we have not heard the issue raised again. Now this sleeper issue seems to have been awakened by a recent report by researchers at the University of California, Berkeley, entitled Flash Cookies and Privacy

Flash cookies, which utilize a little-known capability of Adobe’s Flash plug-in, are a method to store information about a user’s preferences. (Estimates suggest that Adobe’s Flash software is installed on some 98 percent of personal computers.) Flash cookies may be used to provide better functionality to the user by, for example, storing the user’s preferences about sound volume or caching a music file for smoother play-back over an unreliable network connection. Flash cookies may also be used as unique identifiers that enable advertisers to track user preferences and circumvent deletion of HTTP cookies. Because Flash cookies are stored in a different location than HTTP cookies on one’s personal computer, simply erasing HTTP cookies, clearing browser history, or deleting the cache does not remove Flash cookies.

The Flash Cookies and Privacy report found that 54 of the top 100 websites utilized Flash cookies. Some of the Flash cookies found by the researchers were used for function-improving purposes, while others were found to store unique identifiers, which could be used to track the user. Moreover, some of the Flash cookies that stored unique identifiers were used to recreate an HTTP cookie after its affirmative removal by the user (so-called “respawning”). Research also revealed that privacy policies of the top 100 websites surveyed generally did not mention the use of Flash as a tracking mechanism – indeed, only 4 polices reviewed by the study included such a disclosure.

The report is already making some waves: QuantCast, a company that measures web destinations and internet use, has said that it stopped its practice of using Flash cookies to respawn HTTP cookies after the report, which specifically named QuantCast, was released. And the timing of the report coincides with Congress and federal regulators examining behavioral advertising. 

Computer users should be aware of the presence of Flash cookies and, if desired, visit Adobe’s website to learn how to disable Flash cookies. Website operators should, as a best practice, disclose their use of Flash cookies in their privacy policies, including information about how Flash cookies are used and how users can opt out or remove them. 

Consumer Advocates Target Online Behavioral Advertising: Broad Regulation Threatens to Impede Delivery of Relevant Advertising and Business Models for Free Online Content

In the wake of the December 2007 FTC statement proposing self-regulatory principles for businesses that are engaged in online behavioral targeting (click here for earlier blog post), that activity has continued to provoke consumer groups who advocate for government regulation. The legislature in New York has taken notice and is considering a first of its kind bill, the Third Party Internet Advertising Consumer's Bill of Rights Act of 2008, to regulate third parties Internet advertisers’ tracking activities. The New York legislature’s activity coincides with significant opposition in the European Union to online behavioral advertising practices.   

Online behavioral targeting is the process of tracking online users’ behavior and serving ads tailored to that behavior. While the methods vary, the primary methods used online are cookie-based, conveying to advertisers web pages a user visits. Companies may also use search data. This information is sometimes combined with demographic data such as geographic location, to help further personalize advertisements. Glossed over by consumer groups is the fact that tracking usually is conducted anonymously with data collected linked only to a computer’s Internet Protocol (IP) address, not name or other personally identifiable information. In addition, responsible Internet companies are expected to provide clear notice and opportunities for consumers not to participate in such programs. Still, consumer groups have seized on reports of Internet Service Providers contracting with companies such as Nebu-Ad, Phorm and Adzilla who use so-called “deep packet inspection” to collect data on every page a user visits rather than just those that are part of an online advertising network. 

The ongoing debate over online behavioral targeting is significant not only because such targeting enables consumers to receive ads that are more relevant and useful to them, but as the FTC has recognized, restrictions that inhibit companies’ ability to obtain advertising revenue may fundamentally affect the ability of the Internet to continue to offer valuable content for free.

The New York Bill

The New York bill, with versions in the Assembly and Senate (A. 9275 and S. 6441) is based on the Network Advertising Initiative (NAI) self-regulatory principles. The NAI is a group of online advertising firms and it adopted its principles in 2002. The bill would create an extensive regime of consumer notice and choice for third party tracking of different types of consumer online activity. Absent obtaining a consumer’s prior affirmative consent or opt-in, third parties would be prohibited from collecting personally identifiable information online in some situations (when merged with certain other previously collected data). Consumers would have the right to opt-out of any online tracking involving non-personally identifiable information. The bill would require clear notice by third party advertising companies on their own sites of their profiling activities, the types of data they collect, how they use the data, the opt-out process, and the length of time the data is retained. And, it would require third party advertising companies to contractually require the sites to whom they provide services to include notice and opt-out options.  

Notably, the bill would prohibit a third party from tracking information from websites when it does not have a contractual relationship with the website owner. This provision could have major implications for the companies described above that contract with Internet Service Providers to monitor surfing activity across all websites a consumer visits. The bill is also significant because it would effectively create a national law – companies with a national online presence would necessarily be doing business in New York as well.                    

The European Union 

The press has recently reported about controversy in the U.K. concerning reports that the country’s three largest ISPs, BT, Talk Talk, and Virgin Media, had contracted with Phorm for behavioral targeting services. A U.K. think tank, the Foundation for Information Policy Research (FIPR) submitted an open letter to the U.K Information Commissioner charging that Phorm’s activities violate British privacy law and the European Union’s Data Protection Directive by not affording consumers opt-in choice for the tracking. Phorm is claiming that it uses a cookie with a random number assigned to track information so that it does not collect personally identifiable information. 

The issue of online monitoring continues to draw the attention of European Union regulators with more activity expected in the near future. Although the E.U. approved the Google-Doubleclick merger, the E.U. Article 29 Working Party comprised of data privacy regulators from each of the E.U.’s member states has stated that even search engines based outside of the E.U. may fall under the E.U. Data Protection Directive. In addition, the Chairman of the Article 29 Working Party has asserted that IP addresses standing alone constitutes personally identifiable information. This stands in contrast to how IP addresses are viewed in the U.S. The Article 29 Working Party is expected to issue a report in April concerning the privacy implications of Internet search engines, which should further address these issues.     

Industry and Interest Group Guidelines        

In addition to the activity discussed above, industry and consumer interest groups continue to propose new guidelines. The NAI announced late last year it is planning to revise its guidelines while just last month the Interactive Advertising Bureau – an organization comprised of many leading Internet companies – issued self-regulatory guidelines similar to the FTC’s but designed to give companies more flexibility in their approach to notice and choice. Earlier this month, the Center for Democracy and Technology issued its Privacy Principles for the Development of User Controls for Behavioral Targeting, which focuses on allowing consumers to express their preferences for behavioral targeting, having those preferences remain in place until altered by the consumer, and encouraging companies to have readily available and easily understandable policies.
