A manufacturing company is operationalizing an AI-driven quality control system. The project manager needs to ensure data privacy and regulatory compliance due to the critical nature of protecting sensitive operational data. What is an effective technique that addresses these requirements?

Data anonymization is a data processing technique that removes or modifies personally identifiable information (PII) or other sensitive data. In the context of an AI quality control system, this would involve stripping data of identifiers like specific machine serial numbers, operator IDs, or exact timestamps that could be linked to sensitive operational contexts. This directly addresses the core requirements of data privacy and regulatory compliance (such as GDPR's principle of data minimization) by ensuring the dataset used for AI model training and operation does not contain sensitive, identifiable information, thereby mitigating privacy risks.

A. Implementing a zero-trust architecture for network security: This is a network security model for controlling access to resources, not a technique for protecting the privacy of the data content itself during AI processing.
B. Utilizing a secure multiparty computation framework: This is a cryptographic method for multiple parties to compute a function jointly without revealing their private inputs, which is generally more complex than needed for a single company's internal system.
D. Using a hybrid encryption scheme for storage: Encryption protects data at rest and in transit, but the data must be decrypted for the AI model to process it, leaving it exposed during computation. ---

In the Core Functions section, under "Protect-P: Data Processing Management (PR.DM)," the framework discusses implementing controls to manage data processing, which includes de-identification techniques like anonymization to reduce privacy risks. (See Subcategory PR.DM-P7).
