Department of Health, Ex Parte Source Informatics Ltd in the UK concern privacy and health data protection, data deidentification and re-identification, drug detailing (marketing), commercial benefit from required disclosure of personal information, clinician privacy and duty of confidentiality, beneficial and unsavory uses of health data, regulating health technologies, and considering data as speech.
