• Abstract:

  Enterprise financial data security storage methods mostly rely on traditional means such as localized encryption, regular backups and firewall isolation, which leads to poor storage security because static encryption cannot withstand dynamic attacks in the cloud environment. In this regard, a secure storage method for enterprise financial data based on cloud computing technology is proposed. Through the sequence segmentation of enterprise financial data sets, the continuous data flow is divided into normal and abnormal sequences according to business logic and statistical characteristics, and allocated to buffer areas with different capacities to realize orderly data storage and fast retrieval. Based on the distributed computing capability of cloud computing, sparse transformation and reconstruction algorithms are used to compress high-density data to reduce transmission bandwidth and storage overhead, while redundant information is eliminated through cluster analysis. Combining homomorphic encryption and blockchain technology, the compressed data is dynamically encrypted and stored in the cloud distributed node. In the experiment, the proposed method is verified for storage security. The test and comparison results make it clear that the average data leakage rate is 0.3% when the proposed method is used for secure storage of financial data, which has a more ideal storage effect.
