Abstract
With the rapid development of information technology, data security faces unprecedented challenges. Traditional data security technologies are increasingly showing limitations in addressing the complexities of modern network environments. Blockchain technology, characterized by its decentralization and immutability, offers new solutions for data security. This study aims to explore the application of blockchain technology in data security. Through a literature review, it examines the principles of blockchain technology and its alignment with data security requirements. Case analysis is employed to dissect the data security mechanisms provided by blockchain technology across various scenarios. The findings indicate that blockchain technology can establish a trustworthy data storage environment, ensuring data integrity and consistency. Smart contracts enable automated and transparent execution of security policies, while distributed ledgers make data traceability possible, effectively preventing data leakage and unauthorized alterations. The innovation lies in the deep integration of blockchain characteristics with core data security needs, proposing a novel data security management fr amework. This fr amework not only enhances data security but also optimizes data management processes, providing theoretical references and practical guidance for the field of data security. It holds significant implications for promoting the widespread application of blockchain technology in data security.
