Côte d’Ivoire recently implemented fingerprinting to obtain a unique patient identifier.
The poor quality of the fingerprint, or more precisely of the stored templates, is the source of false positives (up to 10%) and false negatives.
Solutions proposed for CI are to:
- improve the quality threshold, under which a fingerprint cannot be validated,
- allow visualization of the fingerprint image during capture,
- review the SOP and train providers,
- increase the matching threshold, above which 2 templates are seen as potential match.
No results yet as this is being put in place.
