Abstract

The invention provides a method, device and storage device for access control of geoscience big data images. An access control method for geoscience big data images is to use invisible watermarks to realize the close combination of access control and accessed entities, and develop a new access control method; an geoscience big data image access control device and storage device for A method for access control of geoscience big data images is realized. The beneficial effects of the present invention are: through the invisible watermark technology, the effectiveness and rationality of data access control and utilization are improved, the time and space complexity of access control is reduced, and the information security of geoscience big data images is enhanced.

Description

technical field [0001] The present invention relates to the field of big data, in particular to a method, device and storage device for access control of geoscience big data images. Background technique [0002] Due to the vigorous development of the Internet, image information processing, big data analysis, and aerospace, there are now a large amount of geoscience information and images that can be obtained by ordinary users on the Internet (geoscience big data includes: remote sensing images, maps, 3D geological maps, Tiantu, etc., belong to massive distributed rich media data). But it is precisely because of the huge amount of data that most of the image data that needs to be kept secret and cannot be accessed completely, or can only be partially accessed, has not been carefully classified and protected, and data abuse may occur. [0003] Existing access control methods, such as role-based access control, separate managed entities from access control policies and manage ...
