Abstract: An expired map data based anti-counterfeiting method, apparatus, storage medium and device. The method includes: acquiring currently expired map data; adding anti-counterfeiting content to the currently expired map data and storing the currently expired map data containing the anti-counterfeiting content; and creating and storing a current anti-counterfeiting map based on basic map data and the currently expired map data containing the anti-counterfeiting content. Using the anti-counterfeiting content added to the currently expired map data as the anti-counterfeiting map data, compared with using false data for anti-counterfeiting in the map data, increases the concealment of the anti-counterfeiting data in the anti-counterfeiting map and improves the anti-counterfeiting effect of the anti-counterfeiting map.
