dc.description.provenance - public display

We are currently implementing the Brazilian Chamber of Deputies repository with Dspace 1.5.1 (xmlui). We are having trouble with de metadada field dc. description.provenance. The dc.description.provenance is displayed in the full record item. Doesn't seem that dc. description.provenance should be displayed in the full record item because it shows some kind of private information, like checksums and email address. For public display doesn't make any sense having the dc.description.provenance available. What should I do in order to disable from the full record item the dc. description.provenance? Or hide the dc.description.provenance for the public.
