Private sharing provides the ability to discuss details of living people with one person or within a small group of people who are subject to ethical guidelines prohibiting redisclosure. Private sharing is standard practice for supervisory relationships, credentialing, teaming, and scholarship in many professions. Privately sharing information about living people is common, for example, in ethical genealogists’ reports that identify, without permission, potential heirs, biological kin of adoptees, and relatives of service members unaccounted for from past conflicts.
Publishing implies dissemination and distribution to the public. Recorded lectures are publications requiring either informed consent of identified individuals or anonymizing. Similarly, lectures outside small closed groups require informed consent of identified living individuals or anonymizing.
Information widely available to the general public is not subject to privacy restrictions, although ethical considerations may affect even public information about a living person.
