Data Security Algorithm for Public Decision Support System Based on Blockchain Technology

It explores data security algorithms pertinent to public decision-making support systems using blockchain technology in solving core issues of the public decision-making process, such data security, openness, and efficiency. Based on the features of decentralization, tamper-proofing, and encryption of blockchain technology, a framework on data security for public decision support systems could be put forward, including data encryption, digital signature, verification, and implementation of smart contracts. Particular strategies for putting plans into action. By integrating public decision support systems demand analysis, this article develops a security algorithm design centered around blockchain. It demonstrates, through application scenarios and case studies, that this framework has considerable impact on enhancing data security, transparency, and decision-making efficiency. The findings of this study demonstrate the wide range of potential uses for blockchain technology in public management, enhancing data processing credibility and efficiency while meeting stringent security standards for decision-making support systems.
