Abstract (en)
[origin: WO2021170645A1] The invention relates to a method for directly transmitting electronic coin datasets between terminals in order to make a payment in a payment system, wherein a first terminal has at least one electronic coin dataset, and the at least one electronic coin dataset has a monetary value and a concealment value as coin data set elements. The method has the steps of: masking a first coin dataset element of the electronic coin dataset, preferably in the first terminal, by applying a one-way function, which is homomorphic for example, to the first coin dataset element of the electronic coin dataset, preferably to the concealment value thereof, in order to obtain a masked electronic coin dataset element; adding a second coin dataset element of the electronic coin dataset to the semi-masked electronic coin dataset, preferably in the first terminal, in order to obtain a semi-masked electronic coin dataset; and transmitting the semi-masked electronic coin dataset to a monitoring entity in order to register the electronic coin dataset. The invention additionally relates to a payment system with a monitoring layer with a database, in which masked electronic coin datasets are stored, and a direct transaction layer, which uses at least two terminals and in which the method can be carried out.
