At least one transceiver is configured to wirelessly receive data from a source node that is external to a vehicle, the data including a unique identifier (ID) of the source node and at least one of: a first location of the source node; a first heading of the source node; a first speed of the source node; and a first object type of the source node. At least one of a camera and a sensor is configured to identify objects located around the vehicle. An anomaly module is configured to selectively indicate that an anomaly is present in the data. A distributed ledger includes a list of unique IDs associated with not-trusted source nodes. A ledger management module is configured to, in response to an indication that an anomaly is present in the data received from the source node, add the unique ID of the source node to the list.
