Efficient way to anonymise interviewee identities for academic research

The question was discussed on tex.stackexchange.com

I'm looking for an efficient way to anonymise interviewee identities using a pseudonym list.
Case studies often use direct quotation from interviews and observational data.
In these cases it is usual to identify the speakers using a pseudonym and/or role label.
Anonymisation attempts to preserve the privacy of research subjects, following the 'do no harm' principle of social and human sciences research ethics.
Using a pseudonym preserves source attribution (i.e. justifies that the quote is an example of actual empirical evidence).

I expect that this requirement is a bit like creating a glossary, a register of names or list keywords used in a document (i.e. create-a-register-of-persons-with-biblatex or create-a-register-of-persons-with-references)

I imagine writing the quotes with correct attribution in my latex document, and they will be replaced when typesetting.
Something like \person{joe} and \personrole{ceo} and a catalogue command like \dramatispersonae that produces a register of the pseudonyms and their roles in a section, somewhat like a glossary, or characters of a play, the dramatis personae.

Perhaps I could do this with bibtex, but I need to the dramatis personae to be separate from the bibliography.

Notes:
I'm not referring to approaches for censoring, redacting or 'blinding' text (i.e. efficient-ways-to-anonymize-a-document)
