摘要 针对现有艺术品流通信息不透明、中心化交易权限不对称等问题,提出一种基于三链的艺术品区块链存证溯源模型。首先,针对艺术品信息单条数据量大的特点,提出基于区块链的对称可搜索加密算法,并结合星际文件系统对艺术品流通记录进行链上链下安全存储。其次,对于艺术品信息有效数据日渐增长的特点,提出基于区块链的倒排快速查询溯源算法,帮助数据用户实现快速溯源定位。同时,首次提出虚假信息联盟链存储失实艺术品流通记录,实现对虚假信息的处理。最后,实验验证了模型的大数据安全存储、快速查询溯源可行性。实验表明该模型可行,查询方法有效。

英文摘要 In order to solve the problems of the current art circulation information is not transparent and the centralized trading authority is asymmetric, this paper proposed a art blockchain certificate traceability model based on three chains. First, in view of the large amount of data in a single piece of artwork information, this paper proposed a blockchain-based symmetric searchable encryption algorithm, and used the interplanetary file system to securely store artwork circulation records on-chain and off-chain. Secondly, for the characteristics of the increasing effective data of artwork information, this paper proposed a blockchain-based inverted fast query and traceability algorithm to help data users realize fast traceability and positioning. At the same time, this paper proposed for the first time that the false information alliance chain stores false art circulation records to realize the processing of false information. Finally, experiments verify the feasibility of the model for big data security sto-rage and fast query traceability. Experiments show that the model is feasible and the query method is efficient.
