FindFace Security Data Storages¶
In this section:
FindFace Security uses the following data storages:
- Tarantool-based biometric database that stores biometric samples (feature vectors) and face identification events.
- Main system database based on PostgreSQL, that stores internal system data, dossiers, user accounts, and camera settings.
/var/lib/ffsecurity/uploadsthat stores uploaded dossier photos, video files, and such event artifacts as full frames, face thumbnails, and normalized face images.
/var/lib/ffupload/that stores only such event artifacts as face thumbnails.
There are 3 galleries in the Tarantool-based biometric database:
ffsec_dossier_face: biometric samples extracted from dossier photos.
ffsec_events: biometric samples extracted from faces detected in the video.
ffsec_persons: centroids of persons (virtual biometric samples averaged across all person’s faces) and metadata.
