Blockchain Based Integrity Checks

Abstract

Systems, apparatuses, and methods are described for determining, based on blockchain, integrity of software and/or data stored on a vehicle. A computing device associated with a vehicle may determine one or more hash values for software and/or data stored on the vehicle. The computing device may receive values from read-only memory associated with the computing device and/or values from a blockchain of a distributed ledger system. The computing device may determine the integrity of the software and/or data based on the one or more hash values, the values from the read-only memory, and/or the values from the blockchain.

         9 . The method of  claim 1 , further comprising:
 verifying, based on the third hash value, the second hash value; and   based on determining that the first hash value corresponds to the verified second hash value, performing the operation of the vehicle.   
     
     
         10 . The method of  claim 1 , further comprising:
 verifying, based on the third hash value, the second hash value; and   based on determining that the first hash value is different from the verified second hash value, suspending the operation of the vehicle.   
     
     
         11 . The method of  claim 10 , further comprising:
 based on the determining that the first hash value is different from the verified second hash value, one or more of:
 determining a compromised part of the collection of information; or 
 sending a notification that the vehicle has been compromised. 
   
     
     
         12 . The method of  claim 1 , further comprising:
 based on determining that the second hash value is different from the third hash value, determining a version, of a hash value associated with the vehicle, as agreed to by computing devices of a distributed ledger system.
