Abstract: A method and a value document processing system for processing value documents include: ascertaining first identification data by means of which the value documents contained in a plurality of different batches can be identified, in at least one value document processing device; generating assignment data; transmitting the first identification data to an external computing device; comparing the transmitted first identification data with specified second identification data by means of which value documents can be identified that are to be removed from circulation and/or are to remain in circulation; and, if the comparison indicates that at least one value document that is to be removed from circulation is contained in the value documents, identifying the batch in which the at least one value document is contained that is to be removed from circulation; and sorting the value documents.

Abstract: A method for processing value documents and to a value document processing system, involve: ascertaining first identification data by means of which the value documents contained in at least one batch of value documents can be identified, in at least one value document processing device; transmitting the first identification data to an external computing device; ascertaining first sorting data in the external computing device by comparing the transmitted first identification data with specified second identification data by means of which value documents can be identified to be removed from circulation and/or remain in circulation; transmitting the first sorting data from the external computing device to the at least one value document processing device; and sorting the value documents contained in the at least one batch in the at least one value document processing device on the basis of the transmitted first sorting data.

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.

Abstract: The invention relates to a payment system and a method for directly transmitting electronic coin datasets between terminals, wherein a monitoring entity registers anonymous masked electronic coin datasets. The method has the following steps in a first terminal; receiving an electronic coin dataset, said at least one electronic coin dataset having a monetary value and a concealment value; masking a modified electronic coin dataset or the received electronic coin dataset by applying a one-way function to the electronic coin dataset in order to obtain a masked electronic coin dataset; linking the masked electronic coin dataset to a pseudonym in order to obtain a pseudonymized masked electronic coin dataset, and transmitting the pseudonymized masked electronic coin dataset to the monitoring entity.

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.

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.

Abstract: A method for directly transmitting an electronic coin data record between first and second terminals, with the following steps carried out by the second terminal: receiving the electronic coin data record from the first terminal, wherein the at least one electronic coin data record includes a monetary amount and a concealment amount; generating a modified electronic coin data record using the received electronic coin data record; masking the modified electronic coin record by applying a homomorphic one-way function to the modified electronic coin record in order to obtain a masked modified electronic coin record; sending a registration request for the masked modified electronic coin data record to a monitoring entity. A currency system and a payment system includes a decentrally controlled database in which masked electronic coin data records are stored; and a direct transaction layer including at least two terminals in which the method can be carried out.

Abstract: A device for directly transmitting electronic coin data records to another device includes accessing data storage, such that an electronic coin data record is stored in the data storage; an interface at least for outputting the at least one electronic coin data record to the other device; and a computing unit configured to mask the electronic coin data record in the device by applying a homomorphic encryption function to the electronic coin data record to obtain a masked electronic coin data record for registering the masked electronic coin data record at a monitoring entity; and to output the electronic coin data record using the interface. A payment system has a monitoring layer including a database in which masked electronic coin data records are stored; and a direct transaction layer including at least two devices in which the method can be carried out.

Abstract: A method for verifying an object is furnished with a security element in which the security element is manufactured in a multi-step method with register variations and contains in a check field an individual characteristic feature of the security element in the form of a superimposition of at least two areal regions. The check field of the security element is optically captured by a camera, the area proportions of the superimposed and not superimposed areal regions are determined and from it a check value for the individual characteristic feature of security element is formed and compared with a reference check value, on which a verification result for the object furnished with the security element is created.
