Multi-Instance Contingent Fusion for the Verification of Infant Fingerprints

Table 1

Supplementary factors to be considered in the selection of a biometric trait for identifying children [27].

Biometric trait	Ease of capture (challenges)	Intraclass variation	Parental concerns	Dataset availability	Applications
Face	Easy (variation in illumination and expression, closed eyes)	Large (due to craniofacial morphology)	Minor	Not available in the public domain	Identification documents and surveillance
Fingerprint	Relatively easy	Increase in the ridge structure of the fingers	Moderate	Not available in the public domain	Forensics, national identification, and immigration
Iris	Difficult (closed eyes, crying)	None	Major (intrusive capture)	Not available in the public domain	Immigration, national identification and refugee identification
Palmprint	Difficult (closed fist, concavity of the palm)	Increase in the size of the palm	Moderate	Not available in the public domain	Same as that of fingerprints
