5.3.3 Anonymization of 3D anthropometric data

According to the General Data Protection Regulation (GDPR) of the European Union (EU), personal data is defined as any information relating to an individual that can be used directly or indirectly to identify an individual. GDPR applies to companies or entities that collect and handle personal data from EU-based individuals, regardless of where the data is processed. The 3D body scans can include personal data in the texture. Although the 3D body scan excluding the texture is not recognizable, it is more secure to remove the 3D facial features. A sustainable ecosystem designed with a vision of adding new data and re-using it in aggregated format recommends including a step of anonymization.

Durá Gil et al. (2020) propose a methodology that incorporates a synthetic human face to every 3D body model. This is performed in a three-step process:

1. The first step identifies the vertices in the raw scan that lay on the model’s face.

2. Then, the identified vertices are removed, obtaining a de-faced scan.

3. Finally, the registration process of the 3D body scan will add a synthetic human-looking face to the avatar.
