The proposed definition does not only provide a strong notion of security and privacy, but also covers features which are important for practical use. An efficient realization is presented and proven to fulfill the proposed definition. The resulting building block is the first one that allows for anonymous two-way transactions, has semi-offline capabilities, yields constant storage size, and is provably secure.Maths for computer scientistsbicsscAnonymitätBezahlsystemeLoyalitätssystemeLoyalty SystemsPayment SystemsPrivacyReputation SystemsReputationssystemeMaths for computer scientistsNagel Matthiasauth1323291BOOK9910586567703321Anonymous Point Collection - Improved Models and Security Definitions3035452UNINA
