Restrict users from entering or viewing master data on the basis of Item group

Dear Gurus

My client requires that his employees from different department should not be able to view or add master data not related to them. They only filter I can imagine is on Item Group level. Can I restrict users from entering master data or viewing data via stored procedure on the basis of Item Group?

Or

Is there any workaround for this?

I am using 8.82 PL4
