Abstract

The invention provides an electronic signature processing method, device and system of map data and a storage medium. The method comprises the following steps: selecting linear data from the map data, wherein the linear data refer to road elements formed by shape points; inserting watermark point string data into the linear data; and displaying corresponding electronic signature information in a map according to the watermark point string data. According to the invention, the electronic signature information can be represented through the distance information between the points embedded in the map data, so that the electronic signature can be flexibly added into the map data, the effective recording of the ownership of the data is achieved, the cracking difficulty of the map data is improved, and the copyright of the map data is better maintained.

Description

technical field [0001] The present invention relates to the technical field of high-precision maps, in particular to an electronic signature processing method, device, system and storage medium for map data. Background technique [0002] High-precision maps are an indispensable and important supporting technology for autonomous driving. With the development and popularization of computer technology and the Internet, as well as the advancement of multimedia data storage and transmission technology, the transmission and sharing of digital products has become very easy, which also makes digital Illegal copying of products becomes very easy. [0003] At present, POI (Point of Interest) information in high-precision maps is generally modified, or road elements are processed with special terrain shapes to identify the data ownership of high-precision maps. [0004] However, this marking method of data ownership can only use the geometric information and type attribute information...
