Masking is a strategy often employed in data security and healthcare to protect sensitive information. For example, in a database, instead of displaying the full credit card number as '1234-5678-9876-5432', it might be shown as '1234---5432'. This ensures that critical data remains confidential while still allowing for some level of information to be shared.
