Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be further described in detail with reference to the accompanying drawings and examples. It should be understood that the detailed description and specific examples, while indicating the scope of the invention, are intended for purposes of illustration only and are not intended to limit the scope of the invention.
Referring to fig. 1 to fig. 3, the block chain-based remote sensing result copyright management method provided in this embodiment includes three steps of copyright authentication, copyright purchase, and copyright usage tracking. Specifically, the remote sensing result file is stored in a distributed file system in a distributed mode, a union chain is established, hash information and file description information of the remote sensing result file uploaded by a user can be received and recorded in a block by a union miner, tampering of the copyright of the remote sensing result file is very difficult due to the fact that the block chain cannot be modified, safety of the file is greatly improved due to the distributed storage, the block can be written into the block chain only by the union miner, and other nodes can only read the block.
Copyright authentication is mainly that remote sensing results are uploaded to a distributed file system of a block chain for storage. The specific process is as follows:
locally calculating a hash value of the remote sensing result, namely performing md5 operation on the byte stream of the remote sensing result data to obtain a 64-bit abstract ciphertext, inquiring whether the hash value exists in a block chain, and if so, indicating that the remote sensing result data exists; if not, the copyright author sends a request for submitting the remote sensing achievement to a distributed file system of the block chain, the request comprises description information of the remote sensing achievement and a hash value of the remote sensing achievement, the distributed file system successfully verifies the hash value and the remote sensing achievement file, then stores the remote sensing achievement file in a fragmentation mode, namely, a fragmentation storage form is fed back to the copyright author, the copyright author transmits the remote sensing achievement file fragments point to point according to the fragmentation storage form, and after all transmission is finished, a storage file signature is fed back after distributed storage.
After the stored file signature is obtained, a copyright author sends description information containing the remote sensing result, a hash value of the remote sensing result, the price of the remote sensing result and an order for storing the file signature to a block chain (alliance chain), a miner of the block chain (alliance chain) inquires whether the hash information in the distributed file system is correct or not, if the hash information is correct, the received order is added to a block of the miner, the information of the block of the miner is broadcasted to the whole block chain at the next consensus moment (the miner is selected and recorded based on the share right), and data consistency of the whole block chain is achieved.
Copyright purchase means that a purchaser purchases a file needing remote sensing result through a block chain, and the specific process is as follows:
the method comprises the steps that a buyer inquires a hash value of a remote sensing result to be purchased in a block chain to obtain a copyright author of the remote sensing result, requests for establishing an intelligent contract between the copyright author and the buyer in the block chain, and simultaneously creates a contract account, the buyer stores corresponding purchased gold coins in the contract account, the copyright author receives a payment bill containing the purchased gold coins and confirms feedback delivery information, and the intelligent contract is successfully constructed, namely a purchase order is generated.
The intelligent contract is a code contract for restricting the author and the buyer to obey the transaction principle, the intelligent contract for purchasing the copyright comprises how much the user needs to pay, what copyright is purchased, the obligation that the author needs to agree with the user to purchase the achievement copyright, contract account creation and the like. And the generated intelligent contract is sent to the whole network, and is diffused and stored in the block chain contract chain.
And the contract account downloads a corresponding remote sensing result file from the distributed block chain to the contract account according to the hash value of the remote sensing result to be purchased, verifies the downloaded remote sensing result file, encrypts the downloaded remote sensing result file after the verification is successful, and sends a temporary secret key to the buyer and the copyright author after the monitored intelligent contract is successfully constructed.
And verifying the downloaded remote sensing result file according to the hash value of the purchased remote sensing result, namely recalculating a new hash value of the downloaded remote sensing result file, wherein the new hash value is the same as the original hash value, and the verification of the downloaded remote sensing result file is successful.
After the downloaded remote sensing result file is successfully verified, the encrypting the downloaded remote sensing result file comprises the following steps:
carrying out hash operation on the hash value of purchaser information, purchase order information and remote sensing result to obtain H1, a current timestamp T1 and a T1+ time limit timestamp T2, carrying out a digest algorithm on the above information to obtain M1, generating a temporary key by using a symmetric encryption algorithm for an intelligent contract, and then encrypting a downloaded remote sensing result file by using the temporary key.
The validity period of sending the temporary secret key to the purchaser and the copyright author by the distributed file system of the block chain is generally 30 days, and after the purchaser obtains the temporary secret key, the remote sensing result file is encrypted by using the temporary secret key to download point-to-point from the distributed file system through a distributed storage table in a contract account. After the copyright author obtains the temporary secret key, the sales amount can be obtained from the contract account according to the obtained temporary secret key.
And when the distributed file system of the blockchain sends the temporary secret key to the buyer and the copyright author, the distributed file system also sends a message of order completion to the alliance chain, and the alliance chain miners receive the message and record the update data into the blockchain.
The remote sensing achievement data downloaded by the purchaser through the temporary secret key is encrypted, the encrypted secret key can be generated by md5 after the bit extraction operation is carried out on the copyright author, the purchaser and the remote sensing achievement file, and the generation process is invisible to the purchaser, so that the purchaser can only decrypt the remote sensing achievement file through local decryption software to check the remote sensing achievement data.
Specifically, when a purchaser checks the encrypted remote sensing result, the purchaser needs to fill in purchase order information and a hash value of the remote sensing result, a decoding secret key is generated according to the filled purchase order information and the hash value of the remote sensing result, and the remote sensing result is decoded by using the decoding secret key to obtain the remote sensing result.
And each time the buyer decodes and checks the encrypted remote sensing result, a buyer checking message is sent to the block chain, and the copyright author tracks the use of the remote sensing data through the checking message.
According to the remote sensing result copyright management method, copyright information and transaction flow of the remote sensing result are recorded through the block chain account book, and rights and interests of copyright authors and purchasers are protected by using the block chain. And the problem that copyright authors lose due to management center faults is solved by combining related technologies of cryptography in copyright authentication, copyright purchase and copyright usage tracking processes.
The above-mentioned embodiments are intended to illustrate the technical solutions and advantages of the present invention, and it should be understood that the above-mentioned embodiments are only the most preferred embodiments of the present invention, and are not intended to limit the present invention, and any modifications, additions, equivalents, etc. made within the scope of the principles of the present invention should be included in the scope of the present invention.
