In an opinion issued on June 22, 2010, the EU Data Protection Authorities (Article 29 Working Party) clarified the legal framework applicable to online behavioral advertising – an activity that is becoming a hot topic for discussion as its popularity grows. Among other things, the Article 29 Working Party clearly took the position that it is incumbent upon advertising network providers to “create prior opt-in mechanisms requiring an affirmative action by the users indicating their willingness to receive cookies and the subsequent monitoring of their surfing behavior for the purposes of serving tailored advertising.”

Update: Deep Discussion of DPI
On July 17, 2008, the House Telecommunications and Internet Subcommittee examined the practice of deep packet inspection (DPI), a method for networks and third parties to determine what information users (identified by IP addresses or random ID numbers) are searching for and accessing on the Internet in order to tailor more relevant advertising based on an individual’s interests. DPI is often cookie-based and does not link personally identifiable information with user surfer behavior.
The House Subcommittee’s hearing focused on whether the online advertising industry should be required to use opt-in systems, or whether current opt-out systems adequately protect consumers’ privacy. The July 17 hearing is the latest in a series of efforts by regulators and legislators to better understand behavioral targeting.
