Personal Data Masking
Short definition
Personal Data Masking: Concealing sensitive information in interfaces, transcripts or recordings.
Meaning and how it works
Masking hides sensitive fields in displays or recordings, but the underlying data may still exist and require protection. Protecting telephony and customer data combines technical controls, access rights and organisational processes. Different communication channels can require different safeguards.
Business applications
- Business scenario:
During payment support, an agent reviewing a case cannot see an entire payment-card number.
What to check before implementation
Review lawful data handling, key and access management, retention periods, audit trails and recovery procedures. No single mechanism replaces an overall security policy.
