Patent ID: 8707415

Claim:
A method for storing data, having the following steps: establishing a first connection between a first ID token and a first computer system via a second computer system for reading at least one first attribute from the first ID token, wherein the first connection includes a local connection between the first ID token and the second computer system and a wide area network connection between the second computer system and the first computer system, establishing a second connection between a second ID token and the first computer system via the second computer system for reading at least one second attribute from the second ID token, wherein the second connection includes a local connection between the second ID token and the second computer system and the wide area network connection between the second computer system and the first computer system, sending the first and the second attributes from the first computer system to a third computer system over a further wide area network connection between the first computer system and the third computer system, receiving the data from the third computer system by the first computer system over the further wide area network connection and storing the data in the first computer system, and writing the data into the second ID token via the second connection by the first computer system in order to store the data in the second ID token, wherein a condition for writing the data is that the first connection also still exists, wherein the first and the second connection are respectively connections with end-to-end encryption and a connection oriented protocol, wherein the following steps are performed for establishing each of the first and the second connections: (i) a user is authenticated to the respective first and second ID tokens, and (ii) the first computer system is authenticated to the respective first and second ID tokens, wherein following successful authentication of the user and the first computer system to the respective first and second ID tokens a read access to at least one of the first and second attribute stored in the respective first and second ID tokens is performed by the first computer system for transmission, signed by the first computer system, and transmitted to the third computer system, and wherein the read access by the first computer system to at least one of: the first ID token and the second ID token is effected in order to read the first and second attributes of the respective first and second ID tokens specified in an attribute specification.
