Possible to hide fields except to logged in user?

[mkas]

I want to hide a contact field so only the contact can see it in the portal when logged in.

Use Case:

An ACCOUNT has 3 CONTACTS
I want the contacts to all be able to see each other
Each CONTACT has a BARCODE
I want the logged in CONTACT to be able to see their BARCODE and not the barcode of the other CONTACTS (when looking at them as a contact).

I assume this can be done under the 'make field visible' but don't know the formula to make it viewable only if the record is the logged in users record.

Thanks.

Hello mkas,

It can be done by Security Roles Management. You can read more from this link:

You could create simple notStorable field which would show barcode with text specified for actually logged user. This should be done through service.
