Implementation and validation of face de-identification (de-facing) in ADNI4.

ABSTRACT:

Introduction

Recent technological advances have increased the risk that de-identified brain images could be re-identified from face imagery. The Alzheimer's Disease Neuroimaging Initiative (ADNI) is a leading source of publicly available de-identified brain imaging, who quickly acted to protect participants' privacy.

Methods

An independent expert committee evaluated 11 face-deidentification ("de-facing") methods and selected four for formal testing.

Results

Effects of de-facing on brain measurements were comparable across methods and sufficiently small to recommend de-facing in ADNI. The committee ultimately recommended mri_reface for advantages in reliability, and for some practical considerations. ADNI leadership approved the committee's recommendation, beginning in
