摘要

Watermark embedding embeds a digital watermark in positional information measured by positioner for measuring a current position of the mobile object. The positional information embedded with the digital watermark is outputted by a track information output as track information to a carrying medium. The track information is obtained by track information obtaining from the carrying medium, and detected by watermark detection whether water mark is embedded or not. The track information from which the digital watermark is detected and the track information from which no digital watermark is detected are displayed by track display in different modes.
