Dactiloscopía Comparada

Dactiloscopía comparada is a work by Juan Vucetich, an Argentinian police officer, published in 1904. It is a system for classifying fingerprints, which are unique impressions made by the ridges on the ends of fingers and thumbs. This system is still used in most Spanish-speaking countries.12

Fingerprints are valuable for identification because the ridge patterns are unique to each individual and do not change over time. This makes them an indispensable tool for law enforcement. The practice of using fingerprints for identification is called dactyloscopy. Vucetich's system, inspired by the work of Sir Francis Galton, classifies prints based on patterns like arches, loops, and whorls.12
