基于云存储的电子档案数据跨域安全检索算法研究
Research on cross-domain secure retrieval algorithm of electronic archives data based on cloud storage
摘要
Abstract
Due to the vast quantity and intricate structure of electronic archives,designing efficient data storage and retrieval schemes for cross-domain searches is imperative to enhance retrieval accuracy.In this regard,research has been conducted on a cloud storage-based secure cross-domain retrieval algorithm for electronic archive data.Under optimal storage nodes,the proposed algorithm employs cloud storage nodes to distribute an electronic archive file to different regional storage nodes.It leverages a hierarchical principle to calculate distances between cross-domain nodes and determines the number of cloud storage nodes through threshold grading,achieving tiered storage of electronic archive data.Additionally,this study adopts the Fourier transform method to eliminate duplicate data within elec-tronic archives,thereby boosting retrieval efficiency.The algorithm defines the retrieval space for electronic archive data by measuring the average correlation between the clustering center and all electronic archive data.It then determines satisfaction vectors,assesses the satisfaction level of electronic archive data within the retrieval space,and applies gradient methods to refine these satisfaction vectors.By correlating user search keywords,precise and secure cross-domain retrieval of electronic archive data is achieved.Compared to location-index-based retrieval algorithms and HBase-based retrieval methods,this algorithm exhibits superior self-correlation retrieval perform-ance for electronic archive data,capable of elevating cross-domain secure retrieval precision to over 90%.关键词
