Abstract:
Medical data sharing plays a pivotal role in advancing scientific research and service delivery within the healthcare sector. However, issues related to data security and personal privacy protection have been major obstacles hindering its widespread application. In light of this, this paper explores the application boundaries of privacy-preserving computation technologies in medical data sharing. We first introduce the concept of privacy-preserving computation technologies and their primary technical approaches, such as cryptography, differential privacy, federated learning, etc., and delve into their specific applications in the healthcare field. Subsequently, we analyze the advantages and challenges of privacy-preserving computation technologies in medical data protection, including issues related to data security, data authenticity, and technical complexity. By examining existing medical datasets and examples, as well as conducting simulation experiments relying on privacy-preserving computation technologies, we then determine the application boundaries of these technologies in medical data sharing. Finally, we find that while privacy-preserving computation technologies hold significant potential for safeguarding the security of medical data, they also possess certain limitations that necessitate ongoing research and exploration. Overall, this study contributes to a deeper understanding of the application boundaries of privacy-preserving computation technologies in medical data sharing and provides valuable references for future research.
