Abstract
With the rapid development of information technology, data security faces unprecedented challenges, and traditional security technologies are increasingly showing limitations in addressing complex and dynamic data threats. Blockchain, as a distributed ledger technology, demonstrates significant potential in ensuring data security due to its decentralized nature, immutability, and cryptographic algorithms. This study aims to explore the application mechanisms and effects of blockchain technology in the field of data security. By integrating literature review, case analysis, and technical testing, this research thoroughly examines how blockchain technology enhances data security from multiple dimensions including data storage, transmission, and access control. The findings indicate that blockchain technology can effectively prevent malicious data tampering, ensuring the authenticity and integrity of data. The access control mechanism based on smart contracts enables fine-grained permission management, reducing the risk of data leakage. Moreover, its distributed architecture significantly decreases the probability of single-point failures, thereby enhancing system robustness. Innovatively, this study proposes a hybrid fr amework that integrates blockchain with traditional security technologies, offering new solutions to current data security challenges. This not only enriches the theoretical fr amework of data security but also provides practical and feasible technical approaches for data protection in real-world applications, highlighting the importance of promoting the widespread application of blockchain technology in the domain of data security.
