Abstract
A method for providing a data record of a vehicle to a third party includes: receiving a cryptographic key pair including a public, cryptographic key and a private, cryptographic key; receiving the data record of the vehicle; encrypting the received data record by the public, cryptographic key; transmitting the encrypted data record to a data memory for storing the encrypted data record; generating a cryptographic hash value for the encrypted data record; transmitting the hash value of the encrypted data record to a blockchain database for storing the hash value of the encrypted data record; receiving a request message from a third party for retrieving the data record; generating a first request message to the data memory and a second request message to the blockchain database on the basis of the received request message; transmitting the first request message to the data memory and the second request message to the blockchain database; receiving the encrypted data record from the data memory in response to the first request message and the hash value of the encrypted data record from the blockchain database in response to the second request message; validating the encrypted data record by the hash value; and, when validation of the encrypted data record is successful: decrypting the encrypted data record by the private, cryptographic key; and transmitting the data record in response to the request message from the third party to a server of the third party.
