Abstract:A value–security data governance scenario matrix is constructed from the perspective of human–computer interaction theory. A four-stage data governance sandbox mechanism, including Modeling (M), Experiment (E), Diagnosis (D), and Interpretation (I), is further proposed for the high-value–high-risk data governance scenario. The following findings are obtained. First, a new theoretical perspective and analytical approach are provided for data governance in the digital economy by human–computer interaction theory. Data governance is not regarded as a linear process in which security compliance precedes data utilization or data utilization precedes security compliance. A dynamic balance between data utilization and security compliance is required. Second, a value–security data governance scenario matrix can be established based on the two dimensions of value density and security risk. The key challenge of data governance is identified in the high-value–high-risk scenario, where substantial value can be created through data utilization, while significant losses may occur if data are not effectively protected or are illegally exploited. Third, the MEDI data governance sandbox mechanism enables rule solidification, problem tracing, and rule regeneration through human–computer interaction. The sandbox is therefore transformed from a technical isolation tool into a dynamic data governance system characterized by verifiability, traceability, and regenerability. An embeddable and reusable data governance mechanism framework is provided for the implementation of Article 13 of the Data Security Law, which requires data security to be promoted through data utilization and data utilization to be safeguarded through data security.
