专家：你的病情隐私能否成为大数据的一部分？|数博会

Core Viewpoint - The ownership of patient medical records is a contentious issue, with hospitals, doctors, and patients each claiming rights over the data generated during medical treatment [1][2]. Group 1: Data Ownership and Privacy - Data is recognized as a new production factor, but its ownership remains disputed, particularly regarding patient medical records [1]. - Patients consider their medical records as personal privacy, while doctors argue that their expertise is necessary for data generation, and hospitals claim that without their equipment, data cannot exist [1]. - Ordinary outpatient medical records are typically owned or managed by patients, while inpatient records are managed or owned by hospitals [1]. Group 2: Challenges in Data Utilization - The complexity of data ownership leads to difficulties in data circulation and utilization, with concerns about data leakage and privacy infringement [2]. - The concept of "privacy computing" is proposed as a potential solution, allowing data value extraction without accessing original data, thus addressing ownership ambiguities [2]. - Privacy computing enables collaborative data use without transferring data outside its original domain, mitigating security and privacy risks [2]. Group 3: Technical Aspects of Privacy Computing - Privacy computing faces performance limitations, particularly in distributed models that rely on complex algorithms and frequent data transmission [3]. - New centralized privacy computing models have emerged to alleviate performance issues by encrypting data within a trusted execution environment [3]. - A hybrid approach combining centralized and distributed privacy computing is recommended based on specific needs, balancing data security and performance [3].
