人工智能技术和大数据技术在疫情防控中的广泛应用,已发挥了关键性作用,并将持续深化使用。同时个人信息的数据化,在客观上使得个人隐私边界扩大、隐私归属复杂、多种形式的价值与权益失衡等伦理问题日渐加剧。因此,结合疫情防控需求和伦理学原则,甄别、防范及解决这些隐私问题具有重要意义。从疫情防控中大数据技术的应用范围入手,阐述了疫情防控中隐私困境四个阶段的突出问题、三种典型利益冲突、分析了造成隐私问题的三种原因,明晰处理隐私问题的三条原则,进而综合思考并提出疫情防控中解决隐私伦理问题的对策,以期为缓解或解决疫情防控中的隐私问题提供参考。 相似文献

医疗数据治理与患者隐私保护已成为医疗信息化进程中的重要内容和热点话题,隐私关注研究逐渐成为研究重点。通过借鉴互联网用户的信息隐私关注量表和保护动机理论,构建医疗数据患者隐私关注的一般模型,以问卷调查的形式收集实证数据,采用因子分析与结构方程模型验证提出的假设。结果显示威胁严重性与威胁可能性显著正向影响隐私关注,自我效能负向影响隐私关注,隐私关注正向影响隐私保护行为意愿。基于此,相关组织机构要加强隐私数据管理,提高数据透明度并宣传数据利用价值,努力达成隐私保护与数据使用的平衡。 相似文献

ObjectiveTo demonstrate enabling multi-institutional training without centralizing or sharing the underlying physical data via federated learning (FL).Materials and MethodsDeep learning models were trained at each participating institution using local clinical data, and an additional model was trained using FL across all of the institutions.ResultsWe found that the FL model exhibited superior performance and generalizability to the models trained at single institutions, with an overall performance level that was significantly better than that of any of the institutional models alone when evaluated on held-out test sets from each institution and an outside challenge dataset.DiscussionThe power of FL was successfully demonstrated across 3 academic institutions while avoiding the privacy risk associated with the transfer and pooling of patient data.ConclusionFederated learning is an effective methodology that merits further study to enable accelerated development of models across institutions, enabling greater generalizability in clinical use. 相似文献

We present a software architecture that federates data from multiple heterogeneous health informatics data sources owned by
multiple organizations. The architecture builds upon state-of-the-art open-source Java and XML frameworks in innovative ways.
It consists of (a) federated query engine, which manages federated queries and result set aggregation via a patient identification
service; and (b) data source facades, which translate the physical data models into a common model on-the-fly and handle large
result set streaming. System modules are connected via reusable Apache Camel integration routes and deployed to an OSGi enterprise
service bus. We present an application of our architecture that allows users to construct queries via the i2b2 web front-end,
and federates patient data from the University of Utah Enterprise Data Warehouse and the Utah Population database. Our system
can be easily adopted, extended and integrated with existing SOA Healthcare and HL7 frameworks such as i2b2 and caGrid. 相似文献

ObjectiveThe objective was to develop and operate a cloud-based federated system for managing, analyzing, and sharing patient data for research purposes, while allowing each resource sharing patient data to operate their component based upon their own governance rules. The federated system is called the Biomedical Research Hub (BRH).Materials and MethodsThe BRH is a cloud-based federated system built over a core set of software services called framework services. BRH framework services include authentication and authorization, services for generating and assessing findable, accessible, interoperable, and reusable (FAIR) data, and services for importing and exporting bulk clinical data. The BRH includes data resources providing data operated by different entities and workspaces that can access and analyze data from one or more of the data resources in the BRH.ResultsThe BRH contains multiple data commons that in aggregate provide access to over 6 PB of research data from over 400 000 research participants.Discussion and conclusionWith the growing acceptance of using public cloud computing platforms for biomedical research, and the growing use of opaque persistent digital identifiers for datasets, data objects, and other entities, there is now a foundation for systems that federate data from multiple independently operated data resources that expose FAIR application programming interfaces, each using a separate data model. Applications can be built that access data from one or more of the data resources. 相似文献
