Objective: We propose a matrix for setting different standards, which is responsive to context and public expectations. Methods: The law and ethics applicable to anonymization were reviewed in a scoping study. Social science on public attitudes and research on technical methods of anonymization were applied to formulate a matrix. Results: The matrix adjusts anonymization standards according to the sensitivity of the data and the safety of the place, people, and projects involved. Conclusions: The matrix offers a tool with context-specific standards for anonymization in data research. %M 30467101 %R 10.2196/medinform.7096 %U http://medinform.jmir.org/2018/4/e47/ %U https://doi.org/10.2196/medinform.7096 %U http://www.ncbi.nlm.nih.gov/pubmed/30467101
