This chapter is centred on an information-theoretic approach to measure the differential update of the anonymity risk of time-varying user profiles, continuing on previous work published in [116]. We are interested to measure how privacy is affected when new content is posted and how much third-party services get to know about the users when a new activity is shared.…”
