Develop an intuition for Shannon entropy as a measure of information content. Using the game 'Guess Who' as a practical example, this post explains how entropy quantifies the reduction in ambiguity and builds up the mathematical formulation from basic principles.

An Identity Domain is a scope within which we assume that the user's identity can roam freely.

Any ephemeral low-entropy web observable property whose changes are concurrently observable by multiple sites can lead to cross site identity joining.

This method of identity joining does not require coordination between multiple first parties. A single third party embedded within multiple first parties can also use this method.
