Privacy Enhancing Technologies (PETs)

Definition:

An array of technologies that aim to reduce privacy risks associated with data processing.

Commentary:

Generally, these techniques fall into categories of approaches to protecting data that will manipulate or replace or conceal or perturb the original content to render into a state that is no longer or statistically much less vulnerable to reidentification. Common techniques include:
• Categorization
• Tokenization
• Encryption
• Data Masking (numerous substitutions, clipping, bucketing, generalization techniques)
• Anonymization (such as k-anonymity and differential privacy)
