With the help of User rights you can achieve which user can have access of certain rights to see/changes.
Steps: While Creating a new user, under that we have a option to select user rights tab. (e.g. Purchase user can only allow to access of purchase app not for like POS, Accounting, Manufacturing apps etc.)
-In this case you as administrator select blank option over other apps rights and only select User in the Purchase app for Purchase user.
To change over Home page, you required Odoo studio app. to change background of Dashboard.
