  • Patent number: 12147952
    Abstract: A method relates to a terminal for managing electronic coin datasets and to a corresponding terminal. The electronic coin datasets are output by a central issuer entity, wherein each electronic coin dataset has a test value, and the test value is incremented when the electronic coin dataset is directly transmitted between two terminals or the test value is invariant in the event of an action carried out by terminals on the electronic coin dataset. In the method, it is determined whether the electronic coin dataset is displayed by the terminal in the payment system or whether the electronic coin dataset is returned to the central issuer entity. A method in a payment system is provided for managing electronic coin datasets, to a corresponding payment system, and to a monitoring entity.

  • Publication number: 20230103038
    Abstract: The invention relates to a method for directly transmitting electronic coin datasets between terminals, 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. The method has the steps of: determining a masking mode from at least two masking modes, a first masking mode consisting of: masking the electronic coin dataset, preferably in the first terminal, by applying a one-way function to the first coin dataset in order to obtain a completely masked electronic coin dataset; and registering a masked electronic coin dataset in a monitoring entity. The invention additionally relates to a payment system with a monitoring layer using a database, which is controlled in a decentralized manner and 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.

  • Publication number: 20230093581
    Abstract: A method is provided for directly transmitting electronic coin datasets between terminals in order to make a payment in a payment system. 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 to the first coin dataset element of the electronic coin dataset, 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, 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.

  • Patent number: 9913126
    Abstract: A security element of a mobile device comprises a service-provider network subscription associated with a service provider. The security element is arranged such that the service-provider subscription is employable parallel to a user network subscription installed on the security element. A service associated with the service provider thus becomes utilizable on the basis of the service-provider subscription, independently of a user subscription that might be present on the same security element.
