Observing User Engagement, Kentaro Hara

Defensive Publications Series

Content creators can be paid for user engagement by third party observers based on user engagement with their content. However, observers cannot determine user engagement when user agents do not permit access to content consumption history. This disclosure describes web-primitives that enable user agents such as browser applications to enable measurement of user engagement in a privacy-preserving manner. The described primitives are generic enough to enable third party observers to implement tokens based on user engagement, while disabling third-party access to the user’s content consumption history.
