PeopleSoft Field level masking on the search page

Hi,

Is there any provision in the Peopletools or FSCM application that we can mask National ID / SSN or birth date. When we keep one of these sensitive field as key search, we want to mask these field values when it shows on the search page but behind the scene it should keep the original value in order to successfully search and open the page for the key field value. Appreciate your inputs

Thanks, Nav
