After a study on black rhinos in Namibia, new software has been developed by researchers in the United States that could help conservationists keep a watchful eye on the black rhino. The interactive software was jointly developed by researchers at Duke University and analytics software specialist SAS and analyses the footprints left behind by black rhinos. This can be used to monitor their movements and enable conservationists to help keep the animals safe from poachers. The software, called the Footprint Identification Technique (FIT), uses advanced algorithms to analyse over 100 measurements of a rhino's footprint. According to a statement by Duke University, because each rhino's footprint is as distinctive as a human fingerprint, the analysed images can be archived electronically in a global database of previously collected footprint images for matching.
