Problems solved by technology

[0006] (1) Due to its centralized nature, the third-party copyright management system has great security risks. Once betrayed or attacked, it will cause great losses to cultural relics collection units
[0007] (2) The existing cultural relics digital resource management system lacks a copyright protection process, and the approval process is complicated, and it is easy for the infringer to collude with the staff in any link
[0008] (3) The existing blockchain-based cultural relics information management platform solves the problem of storing all information on the blockchain without considering the size of digital resources of cultural relics, and faces the problems of large storage load and low transmission rate when resources are acquired

[0016] (2) The existing cultural relic digital resource files have various data types, large data volume, and high resource consumption. It is difficult to select an appropriate storage solution and ensure its security and appropriate transmission rate
[0020] (3) Existing resource application and approval process is complicated, requiring the participation of personnel from multiple departments, and many personnel participate. If the infringer colludes with the staff, it is easy to have problems in a certain link

Embodiment 1

[0075] The method for safe sharing of cultural relic digital resources provided by the embodiment of the present invention is applied to the party to be protected, and the method includes:

[0076] (1) Resource storage:

[0077] The resources are preprocessed, and the same file is processed with multiple attributes, that is, multi-resolution processing of two-dimensional graphics and image resources. After processing, the resource files are divided into three attribute levels: the resources of the first attribute level S1 are the highest-level resources, which are only allowed to be inquired and obtained by users of the library; the resources of the second attribute level S2 are two-dimensional pictures and images with the highest clarity resources or all data of 3D models; the resources of the third attribute level S3 are pictures, images and 3D model presentation files with lower resolution.

[0078] Store the resource file in IPFS and obtain its storage hash address in IPF...

Embodiment 2

[0086] The present invention proposes a method for safe sharing of cultural relics digital resources based on the blockchain architecture, mainly for digital resources of museum cultural relics, including two-dimensional image resources, three-dimensional models, etc. The present invention mainly comprises the following contents:

[0087](1) Combining blockchain and IPFS, a new security sharing scheme for cultural relics digital resources is proposed, and the overall business process and overall architecture of the scheme are described. This solution utilizes the decentralized nature of the blockchain to solve the security problems of third-party organizations and centralized storage, and records the sharing process of resources in the chain, which cannot be tampered with. The distributed storage of IPFS realizes the safe storage outside the chain of cultural relic digital resources, and reduces the storage and transmission pressure of the blockchain.

[0088] (2) To improve ...

Embodiment 3

[0093] In one embodiment, combined with figure 2 , the overall business process of the present invention includes the following processes:

[0094] (1) The staff perform multi-attribute processing on digital resources of cultural relics, that is, multi-resolution processing of two-dimensional digital resources.

[0095] (2) The staff registers the basic information of the processed cultural relic digital resources, and marks the resource attribute level.

[0096] (3) The digital resources of cultural relics are stored in IPFS, and the resource hash address is returned. Write this address into the basic information as well.

[0097] (4) Write the basic resource information into the blockchain through the storage interface of the smart contract.

[0098] (5) The user logs in to the system through identity authentication, and performs resource query.

[0099] (6) Display the basic resource information according to the user's role authority.

[0100] (7) The user chooses to ...

Abstract

The invention belongs to the technical field of block chains, and discloses a cultural relic digital resource safety sharing method and system, and an information data processing terminal.The cultural relic digital resource safety sharing method comprises a resource storage mode based on an IPFS and an attribute level: performing attribute level processing on cultural relic digital resources, and securely storing complete cultural relic resources in the IPFS, storing the resource basic information containing the attribute level and the hash address of the file in the IPFS into the block chain; in the resource query mode based on role access control, user permission granting is performed by using role-based access control, and the user permission granting corresponds to an attribute level of a resource storage process; and a resource collection mode based on the digital fingerprint: collecting the file in the IPFS by using the hash address, performing user digital fingerprint embedding on the resource, and downloading the resource file embedded with the digital fingerprint by the user. According to the invention, the storage and transmission pressure of the block chain can be reduced, and the authority management process is simplified.

Description

technical field [0001] The invention belongs to the technical field of blockchain, and in particular relates to a method, system, and information data processing terminal for safe sharing of cultural relics digital resources. Background technique [0002] At present, blockchain technology is a new type of decentralized information technology that can safely store digital transactions or other data, and information cannot be forged and tampered with. The transaction confirmation on the blockchain is completed by the consensus of all nodes on the blockchain, and after the consensus is successful, it is packaged and written into the block. Among them, the smart contract on the blockchain implements business requirements in the form of code, which is jointly formulated and maintained by the contract participants, and once deployed, it will be automatically executed when the conditions are met. Its automatic execution feature can reduce human influence on rules and business exec...
