In the privacy debate about behavioral tracking and ad targeting, most folks agree that new rules are needed in areas that are considered “sensitive.” Some activities, like researching health conditions or financial planning, will be off limits for tracking once new rules are in place. Companies won’t be able to use information about those activities when compiling user profiles or targeting advertising, and probably will be obligated to delete such data promptly.
This will impose new policies (and probably new operating practices) on many firms engaged in tracking. A substantial majority (65%) of the tracking companies in the privacychoice database make no mention in their privacy statements of special handling for sensitive information.
The larger players are ahead of the curve. With a few exceptions, each of the top ten ad networks already exclude sensitive information from their targeting matrix in some way. In the most typical formulation, “sensitive” information is defined to include government-issued identifiers (like SSN), insurance plan and financial account numbers, your real-time geographic location (via GPS), and “precise information about past, present, or potential future health or medical conditions or treatments, including genetic, genomic, and family medical history.”
A few ad networks go further, also establishing exclusions around sexual identity and adult activities. Google, for example, says it will not associate the omnipresent DoubleClick cookie with information about “sexual orientation.” Clearsight Interactive and AlmondNet will not store information from “adult and gambling sites.” BlueKai does not collect or share data involving “adult behavior such as drinking, politics, or pornographic content.” Exelate promises not to target ads based on “adult related searches or adult content.”
It is easier for an ad network to promise not to use adult activities if they don’t serve ads or collect data on adult sites in the first place. But mainstream ad networks and measurement firms are present on adult sites. Take a look at the Network Privacy Profile for playboy.com, where you will find DoubleClick, Quantcast, Eyewonder and several others. Those networks are in a position to connect visits to adult sites with a user’s overall profile (and any personally identifiable information, if they have it).
Consumers have some privacy protection in the form of anonymous surfing tools, which are now available in all of the major browsers. But although private browsing mode cuts off access to regular browser cookies on your computer, it doesn’t mask IP addresses or block Flash cookies, which are common across all browsers and are favorite tracking tools for many ad networks. There are technical workarounds, but none within reach of an average consumer.
As regulations emerge, here are two predictions:
- Use of sexual orientation will be off-limits in behavioral targeting as a matter of law, but activities on adult sites will not. While advocates want to circumscribe targeting as much as possible, they will pick their battles. (Thus the recent proposal from a coalition of privacy advocates only suggested sensitizing information about sexual orientation and “personal relationships.”)
- In the long run, as opt-out (or even opt-in) choices become more prevalent and robust, companies will extend their definition of sensitive categories beyond non-controversial areas like finance and health. This will be an easy way to make consumers more comfortable, particularly if new rules require companies to show users what’s in their own profiles.
