Options

ATokenization
BAnonymization
CObfuscation
DDynamic mapping

Explanation

Tokenization is a data protection method that replaces sensitive data with a unique, non-sensitive identifier while retaining the ability to link back to the original value.

Common mistakes.

B. Anonymization irreversibly removes identifying information from data, making it impossible to link back to the original values.
C. Obfuscation makes data difficult to understand but does not necessarily maintain a reversible link to the original values, often relying on complex algorithms rather than a direct mapping.
D. Dynamic mapping is a general term that doesn't specifically refer to a data protection methodology designed for reversible value connection.
