Just saw Richard Fitton's post of 11 July. [ https://www.hifa.org/dgroups-rss/quality-124-digital-identity-3-confiden... ]
I think the discussion of confidentiality, secrecy, privacy and anonymity operates on distinct levels in respect of medical records, on one hand, and medical research, on the other.
With medical records, the purposes of keeping patient information confidential or secret include 1) the Hippocratic Oath ("...whatsoever I shall see or hear in the course of my profession, as well as outside my profession in my intercourse with men, if it be what should not be published abroad, I will never divulge, holding such things to be holy secrets."), and 2) to preserve the patient's data from the interests of potentially unwelcome eyes, such as those of insurance companies, banks and the State.
In medical research, there is often the added concern about letting friends, family and the neighbouring community know about individuals' medical conditions, and the impact of any de-anonymisation on the research project itself. In research projects, anonymisation must usually be done in such a way that it is impossible to reverse - so that noone, not even the computer or data staff, can track back to an individual. This kind of anonymisation is usually not practised with medical records.
BTW, this post originally caught my eye because of the comment that "she thought [the UN ID2020 initiative] was "Big Brother--ish. (*** Aldous Huxley had published in 1932 his futuristic novel *Brave New World*"...). Wrong dystopian novel - "Big Brother" is from Orwell's 1984, not Huxley's Brave New World....
