The full title of the project is “Really Enforceable Solution to Protect End-users Consent & Tracking Decisions”. Based on an extensive study of existing patterns of tracking, we develop a detailed standard mechanism for communicating users consent and tracking decisions via HTTP headers. Moreover, a set of client-side and server-side software (e.g. web-browser plugins) support the legal enforcement of the expressed consents, e.g. by sending the required identifiers or legally binding emails. Soheil Human and Ben Wagner are the project leads representing WU Wien and Max Schrems is the project lead from the NOYB-side. The project is funded by the NetIdee programme of Internet Privatstiftung Austria (IPA).
