Data Security Mechanism of Digital Library Based on Blockchain

Blockchain technology has unique advantages in the construction of smart libraries, but its centralized storage method and unlimited replication of dual data bring unreliable data, reader privacy, and intellectual property issues to smart libraries. This article proposes a deep integration of digital twin and blockchain technology, utilizing the decentralized and tamper resistant characteristics of blockchain to store digital twin data in intelligent libraries. The experimental testing of this study shows that the evaluation accuracy of the blockchain library data security evaluation model based on the SAE Kmeans++algorithm reaches 99.8%, which is significantly improved compared to traditional methods. This means that the security system design based on blockchain not only meets the national requirements for the internal network information security protection capability of libraries, but also meets the relevant market requirements for IDC security.
