Query: Privacy-Protecting Techniques for Behavioral Data: A Survey   Our behavior (the way we talk, walk, or think) is unique and can be used as a
biometric trait. It also correlates with sensitive attributes like emotions.
Hence, techniques to protect individuals privacy against unwanted inferences
are required. To consolidate knowledge in this area, we systematically reviewed
applicable anonymization techniques. We taxonomize and compare existing
solutions regarding privacy goals, conceptual operation, advantages, and
limitations. Our analysis shows that some behavioral traits (e.g., voice) have
received much attention, while others (e.g., eye-gaze, brainwaves) are mostly
neglected. We also find that the evaluation methodology of behavioral
anonymization techniques can be further improved.
