Lecture description: 5G has learned lessons from previous generations and improved the privacy of a subscriber. Still it seems that the privacy is not perfect and there are offerings like Pretty Good Phone Privacy (PGPP) that promise an even better privacy. As a consumer, the question arises, how good is 5G privacy and what are the real privacy risks, if I take PGPP is my privacy really better and what are the potential side effects? In this talk, we will focus on location privacy, its improvements, but also the weak practical issues that come when 5G networks are deployed.
