The document describes a learning package on a dynamic privacy model for web services, which proposes formalizing privacy agreements using a finite state machine to model the private data use flow and define events and negotiation actions to handle changes over time while ensuring user privacy is maintained according to the agreement terms. It provides an example of modeling a purchase service private data use as a state machine to demonstrate how the proposed model works.
