Successful health care, eHealth, digital health, and personal health systems increasingly take place in cross-jurisdictional, dynamic and risk-encumbered information space. They require rich amount of personal health information (PHI). Trust is and will be the cornerstone and prerequisite for successful health services. In global environments, trust cannot be expected as granted. In this paper, health service in the global environment is perceived as a meta-system, and a trust management model is developed to support it. The predefined trusting belief currently used in health care is not transferable to global environments. In the authors' model, the level of trust is dynamically calculated from measurable attributes. These attributes describe trust features of the service provider and its environment. The calculated trust value or profile can be used in defining the risk service user has to accept when disclosing PHI, and in definition of additional privacy and security safeguards before disclosing PHI and/or using services.
成功的医疗保健、电子健康、数字健康和个人健康系统越来越多地发生在跨辖区、动态且充满风险的信息空间中。它们需要大量的个人健康信息（PHI）。信任现在是且将来仍会是成功医疗服务的基石和前提条件。在全球环境中，不能想当然地认为存在信任。在本文中，全球环境中的医疗服务被视为一个元系统，并开发了一种信任管理模型来支持它。目前在医疗保健中使用的预定义信任信念无法转移到全球环境中。在作者的模型中，信任水平是根据可测量的属性动态计算的。这些属性描述了服务提供商及其环境的信任特征。计算出的信任值或配置文件可用于定义服务用户在披露个人健康信息时必须接受的风险，以及在披露个人健康信息和/或使用服务之前定义额外的隐私和安全保障措施。
