I am currently building a project around stellar and I came to the problem of storing public keys of my users.
In my project I need public keys to be able to get the balances and show them on a dashboard. My problem is that when creating the user account on my system I don't want to link it with a public key that will be created on the stellar network. This is done for privacy issues.
I want to know the best practices when it comes to securing and anonymizing the system-user & stellar public key relationship?
