Obfuscation is not a main technical data control area. Obfuscation means hiding or disguising data or information to make it less intelligible or accessible. Obfuscation can be used as a security measure or a privacy-enhancing technique, but it is not a specific type of data control. The main technical data control areas are tokenization, encryption, access controls, and data minimization. Tokenization means replacing sensitive data with non-sensitive substitutes called tokens that have no intrinsic value. Encryption means transforming data into an unreadable format that can only be decrypted with a key. Access controls mean restricting who can access or modify data based on their roles, permissions, or authentication methods. Data minimization means collecting, storing, and processing only the minimum amount of data necessary for a specific purpose1, 2. References: CIPM - International Association of Privacy Professionals, Free CIPM Study Guide - International Association of Privacy Professionals
