With the rapid development and widespread application of big data technology, data has become a key production factor driving social progress and economic growth. However, privacy leakage issues have become increasingly prominent during large-scale data collection, transmission, sharing, and deep mining, with their severity continuously escalating. This paper aims to systematically analyze data privacy protection technologies in the big data environment, focusing on their innovative achievements and practical applications. The article first elucidates the necessity and core challenges of big data privacy protection, then delves into technical innovations and practical implementations. It provides in-depth analysis of cutting-edge technologies such as differential privacy, federated learning, homomorphic encryption, and data desensitization, explaining their principles and characteristics. By examining typical industry scenarios including finance, healthcare, and government services, the paper evaluates their implementation effects and strategic value. Finally, it summarizes and prospects future development trends of big data privacy protection technologies, aiming to provide references for theoretical research and practical exploration in related fields.
