External Bank account Masking

Hi,

Is there a way to mask customer bank account numbers in Oracle based on user? I’m investigating whether any profile options, privileges, or configuration controls can restrict or mask bank account details on the Refund, Receipt, or Invoice pages based on the user/role.

Can you confirm if any of the following are possible, or point me to a configuration or note that covers them:

• Profile options or system security settings for masking.
• Security on the Bank Account object (secure by user/role) to prevent certain users from viewing accounts.
• Role/duty privileges that control visibility of bank account fields.
