Embodiment Construction

[0039] 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.

[0040] Such as figure 1 As shown, the method for complete data uploading in the chain-based remote sensing metadata uploading method proposed by the present invention includes the following steps:

[0041] 1) Verify the identity authenticity of the node user who submits the application data upload, and return a digital certificate.

[0042] 1.1 Verify identity: authenticate the identity information of the node user who submits the application data upload.

[0043] 1.2 Return certificate: After the user is authenticated, receive the returned digital certificate.

[0044] 2) if figure 2 As shown, the remote sensing metadata to be uploaded is independently numbered MID, and en...

Abstract

The invention discloses a remote sensing metadata uploading method based on an alliance chain, and the method comprises the steps: firstly completing the identity authenticity verification of a node user submitting uploaded data, returning a digital certificate of the node user, carrying out the independent numbering of to-be-uploaded remote sensing metadata, encrypting the to-be-uploaded remote sensing metadata, and generating a decryption secret key; splitting the data into a plurality of data blocks through IPFS system service, storing each data block into different nodes in an IPFS network, packaging the data blocks into a set, generating a new data address, verifying the integrity of the data, packaging a digital signature, an MID, a decryption key and the data address into a block, and uploading the block to the alliance chain node.

Description

technical field [0001] The invention belongs to the field of remote sensing image data sharing, and in particular relates to a method for uploading remote sensing metadata based on an alliance chain. Background technique [0002] Driven by the development of aerospace technology and application requirements, more and more satellites are deployed in earth orbit. By the end of 2019, my country has launched 7 civilian high-resolution remote sensing satellites, covering optical, microwave, infrared, etc. Commonly used sensor data, and according to public information, the data stored by the China Resources Satellite Application Center, one of my country's three major civil satellite application centers, will reach 110PB by the end of 2020, and is expected to reach 1400PB by 2025. The "Jilin No. 1" satellite remote sensing data of Guangsatellite Technology Co., Ltd., and the "Beijing No. 2" satellite remote sensing data of Beijing 21st Century Space Technology Application Co., Ltd. ...
