摘要:

随着数据规模快速增长,信息系统普遍面临原始数据安全风险高、复合检索效率低等问题。为此,文章提出一种融合布谷鸟过滤与时序B+树的区块链数据溯源机制。该机制将链下信息系统数据的重要参数上传至链上,利用区块链的不可篡改特性与分布式信任机制保障数据安全。在此基础上,通过链上智能合约将优化后的布谷鸟过滤器嵌入时序B+树的各层节点,采用时间分片策略实现物理隔离存储,利用动态布谷鸟过滤器网络构建层级化哈希指纹体系,并结合事件标签位图聚合实现快速复合查询。实验结果表明,在保持低误判率和高效存储的前提下,该机制的溯源效率较传统键值查询提升了20%以上。

Abstract:

With the rapid growth of storage scale, information systems generally face challenges such as high security risks to raw data and low efficiency in composite retrieval. To address these issues, this paper proposed a blockchain data provenance mechanism integrating cuckoo filters and temporal B+ tree. By uploading key parameters of off-chain information system data onto the blockchain, the mechanism leveraged the immutability and distributed trust of blockchain to ensure data security. On this basis, smart contracts embedded an optimized cuckoo filter into each level of the temporal B+ tree nodes, adopting a time-slicing strategy to achieve physically isolated storage. Furthermore, a hierarchical hash fingerprint system was constructed through a dynamic network of cuckoo filters, combined with event bitmap aggregation to enable rapid composite queries. Experimental results demonstrate that while maintaining a low false positive rate and efficient storage, the proposed system improves provenance efficiency by more than 20% compared to traditional key-value queries.
