Hi everyone,

I am looking for everyone's brain working with me.

THE CASE:

->Using any blockchain to host a massive database of personal and private information for millions of users.

HOW IT MUST WORK:

-> User as acess to a kind of wallet in this database that contains different informations about himself.
-> User can generate temporary keys for other users to acess his information on the database.
-> User can generate temporary keys for other users to change information on the database.

This is the first part.

Based on your answers I will go on to the second one.

Please reesteemit and share it. I really need your help
