Developing countries could be able to track pediatric vaccinations with greater accuracy using a fingerprint-scanning system developed by Michigan State University (MSU) researchers with funding from the Bill and Melinda Gates Foundation. The researchers have created software that makes it possible to precisely match fingerprints of children under five using commercially available equipment. The researchers were tasked with processing images captured by fingerprint sensors using software to compensate for the small size of the children's prints, along with wet and oily skin. They also enhanced accuracy by generating matches based on both thumbs and index fingers. A trial in Africa demonstrated the software was about 70-percent accurate in matching prints, versus 98-percent accuracy in a Michigan-based trial. The disparity in accuracy was attributable to the outdoor setting of the African clinic, which was dusty and humid.
