Problems solved by technology

[0002] At present, map transmission is asynchronously requesting the back-end server on the basis of web through http or https, and the request process is all plain text transmission. Illegal personnel can crawl key data through packet capture tools and obtain map data requested by the front end, greatly reducing Security of map data
At the same time, the existing front-end request data packet can only carry the parameters of the map required by the request, but cannot carry the offsets of different types of maps, resulting in errors in the returned data

Embodiment 1

[0029] see figure 1 , a data security communication method based on web map transmission, comprising the following steps:

[0030] The front end (that is, the requesting end) sends a map data request packet through the TCP protocol. The map data request packet includes a fixed-length protocol header and a customizable GeoJSON protocol body. experience information, the GeoJSON protocol body contains the basic attributes and extended attributes of the requested map; the basic attributes include point, line, area, multi-point, multi-line, multi-face and geometry collection, and the extended attributes include map type and offset quantity;

[0031] After receiving the map data request packet, the back-end server verifies the verification information in it, parses the basic attributes and extended attributes in the GeoJSON protocol body after the verification is passed, and then obtains the front-end required information from the server according to the basic attributes and extend...

Embodiment 2

[0044] see figure 1 , a data security communication system based on web map transmission, comprising a front end and a server, the front end and the server are provided with a memory and a processor, each of the memory stores instructions, and the instructions are loaded and executed by the processor The following steps:

[0045] The front end sends a map data request packet through the TCP protocol, and the map data request packet includes a fixed-length protocol header and a customizable GeoJSON protocol body, and the protocol header contains verification information for back-end server verification. The GeoJSON protocol body contains the basic attributes and extended attributes of the requested map; the basic attributes include point, line, area, multi-point, multi-line, multi-face, and geometry collection, and the extended attributes include map type and offset;

[0046] After receiving the map data request packet, the back-end server verifies the verification information...

Abstract

The invention relates to a data security communication method based on web map transmission, comprising the following steps: the front end sends a map data request packet through the TCP protocol, and the map data request packet includes a fixed-length protocol header and a customizable GeoJSON protocol body , the protocol header includes verification information for backend server verification, and the GeoJSON protocol body includes the basic attributes and extended attributes of the requested map; after receiving the map data request packet, the backend server verifies the verification information therein Information, after the verification is passed, the basic attributes and extended attributes in the GeoJSON protocol body are parsed, and then the map data required by the front end is obtained from the server according to the basic attributes and extended attributes, and finally the map data is returned to the front end. The invention can improve the security of map data transmission, and can quickly and accurately analyze geographical information.

Description

technical field [0001] The invention relates to a data security communication method and system based on web map transmission, belonging to the field of mobile communication data transmission. Background technique [0002] At present, map transmission is asynchronously requesting the back-end server on the basis of web through http or https, and the request process is all plain text transmission. Illegal personnel can crawl key data through packet capture tools and obtain map data requested by the front end, greatly reducing Security of map data. At the same time, the existing front-end request data packet can only carry the parameters of the map required for the request, but cannot carry the offsets of different types of maps, resulting in errors in the returned data. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a data security communication method based on web map transmission, which can prevent reptil...
