METHOD FOR PROVIDING VERIFIED INFORMATION ABOUT A TRAFFIC SIGN, TRAFFIC SIGN SYSTEM AND METHOD FOR A NAVIGATION SYSTEM FOR VERIFYING A TRAFFIC SIGN

摘要

A method is proposed for providing verified information about a traffic sign. The method includes receiving information about the traffic sign from an information source and checking whether the information source is an authorized information source. Only when the information source is an authorized information source does the method further include storing the information about the traffic sign in a blockchain database. The method further includes allowing read access to the blockchain database.
