Using Google Ocamlfuse to mount a Google drive without root user being able to see files

I have a server with a lot of unused processing power. I have a friend who does some modeling, calculations, etc., and would like to invite him to use my server. However, I want to give him assured privacy that I cannot view his data. I know that with ocamlfuse he can mount his google drive onto his home folder. But then I would still be able to look inside that folder, right? Is there a way to give him the privacy he needs?
