医学教育大数据隐私保护治理
Privacy protection and governance of medical education big data
摘要
Abstract
Objective To explore privacy protection technologies and strategies for medical education big data in the process of data collection,storage,and sharing,in order to improve data uti-lization and explore its educational value.Methods Analyze the sources and privacy protection chal-lenges of medical education big data,propose anonymous technology and differential privacy tech-nology for the data collection stage,encryption technology and audit mechanism for the data stor-age stage,and federated learning technology and blockchain technology for the data sharing stage.Results Each stage of technology addresses specific privacy risks through targeted design:the k-anonymity model reduces the recognition probability of a single record to 1/k by generalizing quasi identifiers,which can reduce identity inference risks by more than 70.0%;The symmetric encryption algorithm achieves an encryption efficiency of 100MB/s for stored data,and when combined with an audit mechanism,it can increase the data tampering detection rate to 99.8%;Federated learning achieves zero leakage of raw data through distributed model training in collaborative scientific research across multiple universities;Blockchain technology utilizes tamper proof features to achieve secure sharing of cross institutional data.Meanwhile,management strategies provide institutional guarantees for the implementation of technology.Conclusion The combination of technical protection and man-agement strategies can effectively enhance the privacy protection level of medical education big data,promote its maximum utilization in a safe and reliable environment,and provide strong support for the medical education industry.关键词
