Processing system using a block-chain for authorizing a user of a building or vehicle

1. A processing system for a plurality of users of a building or vehicle, the processing system comprising:

a plurality of local nodes arranged in the building or vehicle, wherein each local node stores a copy of a block-chain; and

a processing unit, which is coupled to the local nodes, and is configured to receive a processing request of a user and to verify the processing request by comparing a piece of processing information with the stored block-chain on at least one of the local nodes, to grant access authorization to the user,

wherein the processing information includes a piece of information from biometric data of the user,

wherein one local node of the plurality of local nodes stores the biometric data of the user, and

wherein, when the user is granted access authorization in a station of the block-chain, a positive check result from the station of the block-chain is also entered into the block-chain and the block-chain is distributed to further nodes from the plurality of local nodes.

2. The processing system of claim 1 , wherein the piece of information from biometric data includes at least one piece of information comprising genetic fingerprint, finger line image, gait, facial geometry, hand geometry, hand line structure, hand vein structure, iris, body odor, body size, lip movement, voice timbre, nailbed pattern, ear shape, retina, speech, typing behavior on keyboards, signature, handwriting, and dental impression of the user.

3. The processing system of claim 1 , wherein the access authorization includes authorization for a central locking system or authorization for actuating individual doors of the vehicle.

4. The processing system of claim 1 , wherein the processing unit grants driving authorization to the user using the processing information if access authorization is granted, in order to deactivate an engine immobilizer of the vehicle.

5. The processing system of claim 1 , wherein the processing unit comprises a camera, a fingerprint sensor, and a voice recognition unit.

6. The processing system of claim 1 , wherein the plurality of the local nodes is implemented in a back-end.

7. The processing system of claim 1 , wherein individual blocks of the block-chain include hash values as reference to encrypted data specific to individual users.

8. A method for processing a plurality of users of a building or a vehicle, the method comprising:

storing a copy of a block-chain in a plurality of local nodes;

receiving a processing request of a user;

verifying the processing request by comparing a piece of processing information with the stored copy of the block-chain on at least one of the plurality of local nodes in order to grant access authorization to the user, wherein the processing information includes a piece of information from biometric data of the user; and

storing, in one local node of the plurality of local nodes, the biometric data of the user, wherein, when the user is granted the access authorization in a station of the block-chain, a positive check result from the station of the block-chain is also entered into the block-chain and the block-chain is distributed to further nodes from the plurality of local nodes.

9. The method of claim 8 , wherein driving authorization is granted to the user using a piece of processing information if the access authorization is granted.

10. The method of claim 8 , wherein individual blocks of the block-chain are encrypted with at least one private key or at least one public key.

11. A method for processing a plurality of users of a building or a vehicle, the method comprising:

storing a copy of a block-chain in a plurality of local nodes;

receiving a processing request of a user;

verifying the processing request by comparing a piece of processing information with the stored copy of the block-chain on at least one of the plurality of local nodes in order to grant access authorization to the user, wherein the processing information includes a piece of information from biometric data of the user; and

storing, in one local node of the plurality of local nodes, the biometric data of the user, wherein, when the user is granted the access authorization in a station of the block-chain, a positive check result from the station of the block-chain is also entered into the block-chain and the block-chain is distributed to further nodes from the plurality of local nodes, wherein the processing request is received from the user without using a mobile terminal and without using a smartphone.

12. The method of claim 8 , wherein the plurality of local nodes are arranged in the building or in the vehicle.
