GDPR (TCF)

The Interactive Advertising Bureau (IAB) Transparency and Consent Framework (TCF) allows businesses to operate in a compliant way under the GDPR by providing a standard format to collect and communicate user consent signals to process their personal information. Feedback from EEA regulators on the initial version led the IAB to develop a more detailed set of specific signals. For more information on the TCF, see Transparency & Consent Framework on the IAB Europe website.

How Index Exchange supports GDPR

Index supports the most current version of TCF.

Note: Index no longer supports TCF version 1.

Publishers

Work with your Consent Management Platform (CMP) in order to ensure your integration supports the most current version of TCF.

DSPs

Index passes the consent string for TCF in the consent field of bid requests.

How Index reacts in opt-out cases

When Index determines that an ad request is for a user who has not provided consent, we anonymize certain user information in the bid request sent to our DSPs in the following ways:

  • ip (in the device object): The last octet (IPv4) or two last bytes (IPv6) of the user’s IP address are replaced with a zero(s).
  • lat and lon (in the geo object): Latitude and longitude coordinates are reduced to two decimals which translates to accuracy no less than one third of a mile.
  • All unique IDs from the bid request in the device and user objects that indirectly identify a user are removed.
  • deals (in the pmp object): Audience segment targeted deal IDs are no longer added to the bid request.

For more information about the above bid request fields, see the object descriptions in List of supported OpenRTB bid request fields for DSPs.
