Multi-person participation BIM drawing copyright protection system and method based on block chain

Abstract

The invention belongs to the technical field of network information security, and relates to a multi-person participation BIM drawing copyright protection system and method based on a block chain. Theprotection system comprises a user operation module, a digital signature extraction and verification module, a BIM drawing modification submitting module, an intelligent contract module and a block chain storage module. On one hand, the system achieve a BIM drawing multi-person collaborative design function through combination of a block chain technology, an asymmetric encryption algorithm and anintelligent contract technology, can accurately record a modification record identifier of each designer and uplinks and stores the modification record identifiers, and provides a powerful proof forthe work contribution of the designer; and on the other hand, a copyright division function is set for the BIM drawing completed by cooperation of multiple persons, copyright affiliation division is decided by all designers, and the BIM drawing creation process and copyright division details are recorded by adopting the non-tamperable characteristic of the block chain, so that the fundamental benefit of each creation contributor is guaranteed.

Description

Technical field: [0001] The invention belongs to the technical field of network information security, and relates to a block chain-based system and method for multi-person participation in BIM drawing copyright protection. Background technique: [0002] With the widespread use of BIM technology in architectural design, BIM drawing design is often collaboratively created by multiple people. The collaborative creation of BIM drawings by multiple people leads to complicated and chaotic drawing versions, and the designer's contribution record is not clear, which ultimately leads to the problem of unfounded copyright ownership. ; At the same time, the copyright of BIM drawings relies on traditional website copyright declarations, which are difficult to monitor and difficult to verify after modification, which has caused heavy losses to BIM drawing designers and companies, and has been unable to meet the needs of BIM drawing copyright protection. At present, there are some methods for ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to overcome the shortcomings of the existing technology, design and provide a block chain-based system and method for multiple people to participate in the copyright protection of BIM drawings, which solves the problem of unclear workload records of multiple people's collaborative creation of BIM drawings, and Through the combination of asymmetric encryption technology and blockchain technology, the multi-person collaborative creation function of BIM drawings is realized. The contribution of each designer can be accurately recorded in the blockchain by modifying the characteristic value, and the blockchain cannot be tampered with accurately. Record the creation logo and copyright division of BIM drawings, effectively solving the problem of unclear copyright ownership of BIM drawings
