System And Method For Dynamically Authenticating Map Data Using Blockchains
A system and method for updating map data for updating map data for an autonomous vehicle (AV) is provided. The method includes collecting, using one or a plurality of AV sensors of a first AV, sensor data, and comparing the sensor data collected against map data for determining a presence of potential changed data. The method further includes generating a proof of work (PoW) block including the potential changed data, and collecting, using one or a plurality of AV sensors of a second AV, first verification sensor data. The potential changed data is then compared with the first verification sensor data for generating a first verified map block based on the first verification sensor data, and adding the first verified map block to a first verified map blockchain.

- 1. A method for updating map data for an autonomous vehicle (AV), the method comprising:
collecting, using one or a plurality of AV sensors of a first AV, sensor data; comparing the sensor data collected against map data; when a difference between the sensor data and the map data is above a predetermined threshold, determining that potential changed data is present in the sensor data; generating a proof of work (PoW) block including the potential changed data; generating a set of verification blocks for verification of the PoW block; collecting, using one or a plurality of AV sensors of a second AV, first verification sensor data; comparing the potential changed data with the first verification sensor data; and when the first verification sensor data corresponds to the potential changed data, determining that first verification of the potential changed data is successful, generating a first verified map block based on the first verification sensor data, and adding the first verified map block to a first verified map blockchain.
- 25. A non-transitory computer readable storage medium that stores a computer program, the computer program, when executed by a processor, causing a computer apparatus to perform a process for updating map data for an autonomous vehicle (AV), the process comprising:
collecting, using one or a plurality of AV sensors of a first AV, sensor data; comparing the sensor data collected against; when a difference between the sensor data and the map data is above a predetermined threshold, determining that potential changed data is present in the sensor data; generating a proof of work (PoW) block including the potential changed data; generating a set of verification blocks for verification of the PoW block; collecting, using one or a plurality of AV sensors of a second AV, first verification sensor data; comparing the potential changed data with the first verification sensor data; and when the first verification sensor data corresponds to the potential changed data, determining that first verification of the potential changed data is successful, generating a first verified map block based on the first verification sensor data, and adding the first verified map block to a first verified map blockchain.
- 27. A computer apparatus for updating map data for an autonomous vehicle (AV), the computer apparatus comprising:
a memory that stores instructions, and a processor that executes the instructions, wherein, when executed by the processor, the instructions cause the processor to perform operations comprising: collecting, using one or a plurality of AV sensors of a first AV, sensor data; comparing the sensor data collected against map data; when a difference between the sensor data and the map data is above a predetermined threshold, determining that potential changed data is present in the sensor data; generating a proof of work (PoW) block including the potential changed data; generating a set of verification blocks for verification of the PoW block; collecting, using one or a plurality of AV sensors of a second AV, first verification sensor data; comparing the potential changed data with the first verification sensor data; and when the first verification sensor data corresponds to the potential changed data, determining that first verification of the potential changed data is successful, generating a first verified map block based on the first verification sensor data, and adding the first verified map block to a first verified map blockchain.
