We propose an extension of an existing formal framework, motivated by the need to reason about properties of architectures including group authentication functionalities. By group authentication, we mean that a user can authenticate on behalf of a group of users, thereby keeping a form of anonymity within this set. Then we show that this extended framework can be used to reason about privacy properties of a biometric system in which users are authenticated through the use of group signatures. %G English %Z TC 11 %Z WG 11.3 %2 https://inria.hal.science/hal-01633672/document %2 https://inria.hal.science/hal-01633672/file/428203_1_En_22_Chapter.pdf %L hal-01633672 %U https://inria.hal.science/hal-01633672 %~ INSTITUT-TELECOM %~ ENST %~ TELECOM-PARISTECH %~ PARISTECH %~ IFIP-LNCS %~ IFIP %~ IFIP-TC %~ IFIP-WG %~ IFIP-TC11 %~ IFIP-WG11-3 %~ IFIP-DBSEC %~ UNIV-PARIS-SACLAY %~ TELECOM-PARISTECH-SACLAY %~ IFIP-LNCS-9766 %~ LTCI %~ COMELEC %~ SSH %~ INSTITUTS-TELECOM %~ ANR
