Various systems and methods for implementing secure high-definition map services are described herein. A system for implementing secure high-definition map services includes a processor subsystem; and a storage including instructions, which when executed by the processor subsystem, cause the processor subsystem to: receive map data from a remote data source; authenticate the remote data source; obtain an identifier of the remote data source; add the map data to an entry in an immutable log when the remote data source is authenticated, the entry having an entry identifier; store an association between the identifier of the remote data source and the entry identifier in a secure store; and incorporate the map data into a master map.
