Copyright protection method and system for geospatial data products

Abstract

The present invention provides a copyright protection method and system for geospatial data products. In the issuing stage, the method includes the steps that the geospatial data products with specific digital fingerprint features are generated; according to the permission number, the service life and physical equipment hardware codes of the geospatial data products purchased by a user, authorization permission information containing the digital fingerprint features is generated; authorization permission is deployed according to the authorization permission information. In the use tracking stage, the method includes the steps that an access request for geospatial data is received; whether the authorization permission information is specific permission of physical equipment or not is checked; if not, access is ended; if yes, whether the physical equipment is in the period of validity or not is checked; if not, the access is ended; if yes, whether digital fingerprints in the authorization permission information is consistent with digital fingerprints in the products or not is checked; if not, the access is ended; if yes, the user can have access to spatial data normally. By using the copyright protection method, copyright of the geospatial data can be protected in advance with fine grit and high strength.

Description

technical field [0001] The present invention relates to the application field of geospatial data products, in particular, to a copyright protection method and system for geospatial data products. Background technique [0002] With the widespread application of geographic information systems in society, people's copyright protection and usage tracking of geographic information spatial data are becoming more and more intense. In the era when digital products are more and more easy to be pirated, the problem of copyright protection of geospatial data has gradually become more and more serious. Copyright owners urgently need to know who is using the product and how it is being used. And LBS (Location Based Service) application service providers are also very concerned about the use of geospatial data, because they can use regional hotspots, usage frequency, traffic, etc. for data mining to provide decision-making basis for business intelligence. [0003] At present, in terms of...

Problems solved by technology

However, digital watermarking is still only an after-the-fact copyright protection method.

The digital watermark protection method can only be held accountable after the event, and cannot be prevented in advance, and it is difficult to hold accountable after the event, the cost is high, and the operability is not strong. It is a relatively passive copyright protection method.
