In order to do this successfully, we will have to overcome implementation challenges in privacy-enhancing technologies such as differential privacy. We will also have to pay close attention to emerging technologies such as private synthetic data generation. %M 36995757 %R 10.2196/46700 %U https://www.jmir.org/2023/1/e46700 %U https://doi.org/10.2196/46700 %U http://www.ncbi.nlm.nih.gov/pubmed/36995757
