Embodiment Construction
[0019] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, and do not limit the protection scope of the present invention.
[0020] see Figure 1 ~ Figure 3 , the blockchain-based remote sensing achievement copyright management method provided in this embodiment includes three steps: copyright authentication, copyright purchase, and copyright use tracking. Specifically, a consortium chain is established by utilizing remote sensing achievement files distributed and stored in the distributed file system, and the hash information and file description information of the remote sensing achievement files uploaded by users will be received and recorded in the block by the consortium miners. The unmo...

The invention discloses a remote sensing result copyright management method based on a block chain. The method comprises the following steps: copyright authentication: distributing and storing remotesensing results in a distributed file system of a block chain according to hash values of the remote sensing results, and initiating an order containing description information of the remote sensing results, the hash values of the remote sensing results, prices of the remote sensing results and stored file signatures to the block chain; Copyright purchase: the buyer requests to establish an intelligent contract from the block chain, after the intelligent contract is confirmed by the buyer and the copyright owner, the buyer obtains the purchased encrypted remote sensing result according to thereceived temporary secret key, and the copyright author obtains the sales amount according to the received temporary secret key; And copyright use tracking: when the buyer decodes and checks the encrypted remote sensing result every time, a buyer check message is sent to the block chain, and a copyright author tracks the use of the remote sensing data through the check message. The method ensuresrights and interests of copyright authors and buyers.
Description
technical field [0001] The present invention relates to the field of copyright management of remote sensing data, in particular to a blockchain-based remote sensing achievement copyright management method. Background technique [0002] With the continuous development of science and technology, more and more people are familiar with the field of remote sensing. People use different remote sensing technologies and image processing technologies to analyze arrays, realize product value-added, and pay more and more attention to the copyright of remote sensing results, but infringement and piracy Restricting the further development of the remote sensing field, all participants have suffered greatly, especially the authors and other achievement manufacturers have been in a weak position, lacking the corresponding right to speak, and the enthusiasm for creating new achievements has been hit hard. [0003] Remote sensing results refer to the author's processing of remote sensing imag...
