Need help on advanced security settings

Hello,

I have a guest page which they can see data only if their username is written in "reference" field.

Its okay with advanced security settings they can only see their data. But also there 3 more tables which has detail table of this main table.

Main table has "file number" field. Also other 3 tables has too.

But in this case. They can only see their data in main table. But they can see all the data in others.

I want them to see only the records of "file number" fields match with main table on other 3 tables.

Is there a way to do it? Thanx alot.
