BLOCK CHAIN BASED DIGITAL MODEL SHARING METHOD, DEVICE, AND SYSTEM

摘要

The present invention provides a block chain based digital model sharing mechanism, comprising the following steps: obtaining one first model and signature information thereof published by a model designer, and pushing a disclosure message of the first model and the signature information thereof to a plurality of model analyzers; generating a data block of a block chain, wherein the data block comprises model feature index information generated by extracting model features of the first model by one model analyzer; and packing and encrypting the data block and one check code and then publishing the data block and the check code on a shared platform of a digital model. The digital model sharing mechanism provided in the present invention is safer, and allows publication and transaction of the digital model in a public environment.
