List of Storages

FindFace Multi uses the following data storages:

• Tarantool-based feature vector database that stores object feature vectors and identification events.

• Main system database based on PostgreSQL, that stores internal system data, dossiers, user accounts, and camera settings.

• Directory /var/lib/findface-security/uploads that stores uploaded dossier photos, video files, and such event artifacts as full frames, object thumbnails, and normalized object images.

• Directory /var/lib/ffupload/ that stores only such event artifacts as object thumbnails.

Feature Vector Database Galleries

There are the following galleries in the Tarantool-based feature vector database:

• ffsec_body_events: feature vectors extracted from bodies detected in the video.

• ffsec_body_objects: feature vectors extracted from bodies in dossier photos.

• ffsec_car_events: feature vectors extracted from cars detected in the video.

• ffsec_car_objects: feature vectors extracted from cars in dossier photos.

• ffsec_face_events: feature vectors extracted from faces detected in the video.

• ffsec_face_objects: feature vectors extracted from faces in dossier photos.

• ffsec_user_face: feature vectors extracted from the FindFace Multi users’ photos, used for face-based authentication.

• ffsec_persons: centroids of persons (virtual feature vectors averaged across all person’s faces) and metadata.
