A junior analyst oversees data security by using randomly generated data while keeping the original data in a separate location. Which tool is used by the junior analyst?

Authentication is the process of verifying the identity of a user or system, ensuring that access is granted only to authorized entities. While it is crucial for data security, it does not involve the manipulation or storage of data itself. Therefore, it does not apply to the scenario of managing original data through tokenization.

Antivirus software is designed to detect, prevent, and remove malicious software from computers and networks. While it is essential for protecting systems from threats, it does not address the specific need for managing sensitive data securely through the generation of tokens. Thus, antivirus is not relevant to the task described.

Encryption is a method of converting information into a code to prevent unauthorized access. However, unlike tokenization, encryption retains the original data in its encoded form. The original data is still stored alongside the encrypted version, which is not the approach taken by the junior analyst, who separates the original data entirely.
