Embodiment 1
[0029] Such as figure 1 As shown, the embodiment of the present application provides a cloud service-based spatial big data management method, wherein the method includes:
[0030] Step S100: Construct N spatial databases, including the first database, the second database, and up to the Nth database, each of which contains different types of spatial big data;
[0031] Specifically, the spatial database refers to a database storing spatial data, and N storage databases are constructed, wherein N is a natural number greater than 1. Each of the N databases stores different types of spatial big data information.
[0032] Step S200: Generate a first verification code according to the first database, wherein the first verification code is in one-to-one correspondence with the first database;
[0033] Specifically, the verification code is a unique identification code used to verify the database. Perform hash function calculation according to the first database to generate a first...
Embodiment 2
[0086] Based on the same inventive concept as the cloud service-based spatial big data management method in the foregoing embodiments, the present invention also provides a cloud service-based spatial big data management system, such as Figure 7 As shown, the system includes:
[0087] The first construction unit 11, the first construction unit 11 is used to construct N spatial databases, including the first database, the second database, until the Nth database, and the databases respectively contain different categories of big spatial data;
[0088] A first obtaining unit 12, the first obtaining unit 12 is configured to generate a first verification code according to the first database, wherein the first verification code is in one-to-one correspondence with the first database;
[0089] The second obtaining unit 13, the second obtaining unit 13 is used to generate a second verification code according to the second database and the first verification code; and so on, generate ...

Abstract
The invention discloses a cloud service-based spatial big data management method and system. The method includes: constructing N spatial databases, including the first database, the second database, up to the Nth database, and the databases respectively contain different category of spatial big data; generate a first verification code according to the first database, wherein the first verification code is in one-to-one correspondence with the first database; generate according to the second database and the first verification code The second verification code; by analogy, generate the Nth verification code according to the Nth database and the N-1 verification code, and copy and save all databases and verification codes on M devices respectively to obtain a spatial data set; The data information in the above spatial data set is clustered and divided, and the clustered data information is stored in the N spatial databases respectively, so as to improve the security of spatial data storage and accurately classify and store the spatial data. Effect.
Description
technical field [0001] The invention relates to the field of big data management, in particular to a cloud service-based spatial big data management method and system. Background technique [0002] The rapid development of the mobile Internet has brought human beings into the era of location big data. More and more location-based services (Location Based Services, LBS) are integrated into people's daily life, providing services such as point-of-interest query, real-time location sharing on social networks, route planning and navigation, etc., which provide great convenience for people. The safe sharing and release of big data on location and trajectory cannot be separated from the technical support of location and trajectory privacy protection. [0003] However, in the process of realizing the technical solution of the invention in the embodiment of the present application, the inventor of the present application found that the above-mentioned technology has at least the fo...
