One solution is to put backup files in a single (private) location,
rather than alongside the original file. This is achievable in Emacs
with eg
(setq backup-directory-alist '(("\\`/[^/|:][^/|]*:")
("." . "<HOME>/.emacs.d/backups")))
where ~/.emacs.d/backups is created mode 700. I've used this in my
personal config for years.
A very brief search suggests that this seems to be what newer editors
(eg LibreOffice) do for backup files.
