Abstract: A method, a system, a registry, a repository and a computer program product are disclosed for securely accessing sensitive medical data records stored in a repository. Before accessing security-critical data in the repository, a registration inquiry with a separate registry must be carried out in order to obtain a security token having limited temporary validity, for example in the form of a barcode. A data source and/or a data sink can then use the security token to access the security-critical data in that an index module indexes the data record inquired about on the repository.

Abstract: In at least one example embodiment, the invention relates to a computer-implemented method, a computer-implemented system and a computer program product for controlling the access to splittable resources in a distributed client server system operating in parallel. The resource control system is designed for a plurality of clients connected to the system and is used to maintain consistency of the data. When a client makes a first attempt to access a resource of the server, an exclusive lock for the requested resource is allocated to the accessing client, that blocks the access to the resource for other clients, said exclusive lock only being allocated for a pre-determinable period of time and then automatically discontinued.

Abstract: An approach for signing messages and checking the authenticity of the sender at the receiver is disclosed. For this purpose, a mobile communication network is expanded by a signature function. The transmitted message packet comprises the message and a signature of the message encrypted with a secret key. The mobile radio communication number of the transmitting device is preferably used as the public key. The receiver can check the authenticity of the message by employing a decryption method.

Abstract: A mobile communications device is disclosed for use in an electronic access system for communicating with a central server for processing at least access authorization for an application running on the server. In at least one embodiment, an optical identification signal in the form of a barcode or a photographic recording of the user is captured on the mobile communications device in the form of an identification code and sent together with the mobile number to the server for further processing. The access authorization of the user for the respective application can therefore be verified on the central server. At least one embodiment relates in particular to medical and healthcare-related applications.
