Fingerprints, as most of us know, are composed of whorls, loops and arches. But keep zooming in, and you'll find tiny, tiny sweat pores arranged in patterns equally unique. Scientists in Korea have found a new way to map those pores that could help identify decade-old fingerprint fragments.
PiezoMAT proposes a new technology of high-resolution fingerprint sensors based on a matrix of interconnected piezoelectric nanowires (NWs). The sub-micron dimension of NWs allows for high spatial frequency sampling of every fingerprint feature, enabling extremely reliable fingerprint differentiation through detection of the smallest minutiae (pores and ridge shapes).
The finger pads of people with adermatoglyphia are entirely flat-they have none of the arching or looping ridges that characterize the fingerprints of virtually all humans.
They have developed a new substance called Lumicyano that makes it possible to highlight fingerprints directly, more rapidly and at a lower cost, avoiding the cumbersome processes required until now.
Presne tak, ja som sa to este na skole u doc Jana Hudeca ucil. Ten vzdy srandoval ze ako presvedcit pouzivatelov, aby to neakceptovali je strasit ich moznostou odseknutia prstov.
Len ked chce niekto nieco kupit tak to niekto vyroby a preda.
SDK na detekovanie ci je prst zivy iba z obrazku odtlacku prstu. takmer vobec nevyvetluju ako to funguje (algorithms work by exploiting the fundamental image differences between a live fingerprint and a spoof), ani neuvadzaju aku maju accuracy, takze osobne som k tomu dost skepticky.
ten clovek podla mna zavadza, alebo nevie o com hovori. zaujimave ze sa mu podarilo dostat sa az na taku vyznamnu poziciu a takto z nej ovplyvnuje trh v australii.
