I'm looking for word for a person who handles records, but isn't expected to read them. I'm creating a list of positions within an organization who should have access to certain records. Alongside the people who need to actually read these records, there are other people who handle the records as a practical matter. These are the people who may file and retrieve the information, or carry the key to the filing cabinet, or IT staff who are responsible for data encryption and storage. Anyone who could read the information, but really doesn't have reason to.
It would be good if it carried a connotation of trust and responsibility. The word "fiduciary" comes to mind, as it carries implications of professional ethics. As far as I know, that word applies to finances specifically. "Custodian/custodial" is in the ballpark, but perhaps too specific. Ideally, this word would describe anyone along the chain who has access, but does not act on curiosity outside of their direct job function.
A thesaurus search for "fiduciary" gives curator, depositor, trustee, and guardian. These are all a bit too specific, though "trustee" comes close. A thesaurus search for "custodial" has the same problem. They are all words for someone whose job it is to care for some thing. I want to include people who have access to that thing incidentally as part of their job.
The word can be an adjective (applied to the position), noun (describe the position), or adverb (applied to job function).
"Joe will have (adjective) access to the files." OR "Joe will have access to the files in a (adjective) capacity."
"Joe will have access to the files as a (noun)."
"Joe can access the files (adverb)."
I'm guessing there are existing legal terms for what I'm looking for, which is why I'm reaching out on this SE. I'm not drafting a legal document, though.
Edit: Let me clarify a bit. I'm looking for a way to describe the relationship of existing positions to the information in question. This isn't a new job title or even a primary job duty. The motivation is that I'm creating a list of which job titles have access to certain information, and I'd like to mark a difference between those who are supposed to be reading the information, and those who only have access of a necessity because of the way things work.
