Problems solved by technology

[0003] At present, the access control for geoscience images is still a little rough, and it is aimed at the whole map, and the information in the map cannot be discussed hierarchically, and the access control depends on the access control list in the server, which separates the access control policy from the entity , the implementation of access control requires the participation of the server, and the server must undertake the task of implementing access control
Currently, access control policies applied to geoscience images are not layered, nor are access control policies added to watermarks

Embodiment Construction

[0033] In order to make the purpose, technical solution and advantages of the present invention clearer, the embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0034] like figure 1 As shown, the present invention provides a layered access control method for geoscience big data, which can enable data publishers to implement efficient access control for data visitors to access geoscience images, including the following steps:

[0035] Step 101: the data publisher classifies and stratifies the data in the geoscience image, and establishes an access control strategy;

[0036] Step 102: The data publisher adds watermark information to the geoscience image;

[0037] Step 103: the data publisher encrypts the geoscience image;

[0038] Step 104: the data publisher publishes the encrypted geoscience image on the website;

[0039] Step 105: the data visitor requests access to the encrypted geoscience image on the webs...

Abstract

The invention relates to a layered access control method oriented to geosciences big data. The method can enable a data publisher to realize efficient access control on access of a geoscience image bya data accessing person. The method comprises the following steps: firstly classifying and layering data in the geoscience image by the data publisher, and establishing an access control strategy; then sequentially adding watermark information into the geoscience image by the data publisher, encrypting the geoscience image, and publishing the geoscience image on a website; requesting to access the geoscience image by the data accessing person; and decrypting the geoscience image according to information of the data accessing person and the watermark information, so that the data accessing person can select and view data, hidden in rights, of the geoscience image and close the geoscience image. The method provided by the invention facilitates data management, and the access control strategy is also more detailed and flexible.

Description

technical field [0001] The invention relates to the technical field of big data access control, in particular to a layered access control method for geoscience big data. Background technique [0002] Nowadays, geoscience images have been classified, but the classification of maps is very clear and relatively rigid. Traffic maps and resource distribution cannot be viewed in one map at the same time. However, GIS images, remote sensing geological maps and geological mapping all add a large amount of different aspects of information to an image, and certain types of information cannot be displayed and some types of information are hidden. [0003] At present, the access control for geoscience images is still a little rough, and it is aimed at the whole map, and the information in the map cannot be discussed hierarchically, and the access control depends on the access control list in the server, which separates the access control policy from the entity , the implementation of a...
