Embodiment Construction
[0032] The technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. The specific embodiments described here are only used to explain the present invention, and do not limit the protection scope of the present invention.
[0033] Such as figure 1 As shown, a method for confirming rights and traceability of remote sensing data exchange based on smart contracts proposed by the present invention includes the following steps:
[0034] 1) The user publishes the exchange demand in the system, and recommends the exchange to the user by comparing and calculating the data type, data transaction rights and other information. The process is as follows:
[0035] 1.1 Response to the user's posting requirements: the exchange request issued by the user is stored in the database, and the processing result is returned to the user based on HTTP+JSON.
[0036] 1.2 User demand processing: Read the demand published ...

The invention discloses a remote sensing data exchange right confirmation and source tracing method based on a smart contract, and belongs to the technical field of remote sensing data, and the method is based on the smart contract in a block chain. According to the method, exchange right confirmation and traceability of remote sensing data are realized by using an intelligent contract technology and a data watermarking technology, two parties of remote sensing data exchange publish an exchange demand to a platform, right confirmation is performed on the data through a block chain digital fingerprint technology, and the data is marked by using the digital watermarking technology; when the two parties reach an exchange consensus, a specific process is executed through an intelligent contract to complete transfer of remote sensing data assets, remote sensing data exchange information is transmitted to a block chain, and when remote sensing data dispute occurs, marks of the remote sensing data can be extracted, and traceability can be performed on the remote sensing data by tracing transactions. Compared with the prior art, the method has the advantages that the tamper-resistant and traceable characteristics of the remote sensing data information are realized, and the digital watermarking technology and the block chain digital fingerprint technology are introduced, so that right confirmation of the remote sensing data is facilitated.
Description
technical field [0001] The invention belongs to the technical field of remote sensing data, and in particular relates to a method for confirming rights and tracing sources of remote sensing data exchange based on smart contracts. Background technique [0002] In recent years, with the iterative update of remote sensing technology, more and more people have begun to study and study in the field of remote sensing data. The awareness of data ownership and data protection is increasing day by day. Blockchain technology has been verified for a long time in the current technological network field. It can run stably in various exchange systems. In order to adapt to complex transaction environments and lead to frequent changes in requirements, for Problems such as systematic and convenient smart contract development need to be solved urgently. How to make full use of blockchain technology to provide a safe and credible exchange environment for the remote sensing data exchange platfo...
