Public Health Research, Practice, and Ethics for Justice-Involved Persons in the Big Data Era.

The article briefly examines the emerging role and ethical implications of using big data in public health and discusses these issues as they relate to justice-involved persons (JIPs). Described are the appropriate bounds on data collection for public health as are Web sites featuring mug shots, publicly available court records, and the use of electronic surveillance monitors (i.e., GPS ankle monitors). The initial steps to promote ethical analyses and guideline development in this area are also discussed.
