Amanye amaqiniso awusizo ngesithwebuli somunwe

Kulezi zinsuku, imindeni eminingi futhi ngaphezulu isebenzisa inani lokubona iminwe. Kodwa-ke, abantu abaningi abazi okuningi ngokubakhona kokubona kweminwe. Ngezansi, umhleli womkhiqizi wesithwebuli somunwe uzokuchazela umuzwa ojwayelekile ojwayelekile mayelana nemikhiqizo yokuqashelwa kweminwe:

Isithwebuli somunwe? Isikhumba somuntu sakhiwa izingxenye ezintathu: isikhumba, i-epidermis nezicubu ezingaphansi. Isikhumba esingalingani ezintendeni zethu nasezindaweni ezingaphakathi zeminwe yethu, izinyawo nezinzwani zezinzwane zidala amaphethini ahlukahlukene. Iphethini yomunwe womuntu ingumbala weminwe. Ngenxa yezimpawu zofuzo, yize kukhona iminwe yawo wonke umuntu ehlukile, ahlukile. Ngakho-ke le yiminwe yeminwe ukuthi akekho omunye umuntu.
I-Fingerprint Scanner uhlobo olusha lokukhiya olusebenzisa iminwe yomuntu njengomthwali wokuhlonza. Kuyindlela ephelele ye-crystallition yezobuchwepheshe bokuhlonza iminwe, ubuchwepheshe be-elekthronikhi, ubuchwepheshe obusebenza ngemishini nobuchwepheshe besimanje sehardware. Ngokuvamile, izingidi ezingavulwa ngeminwe yeminwe, amaphasiwedi, amakhadi ahlukahlukene okusebenza nezinkinobho zomakhelwane ezisele zingabizwa ngokuthi isithwebuli somunwe.
Uyini ubuchwepheshe bokuqashelwa kweminwe yemvelo? Isebenzisa ubuchwepheshe bokuqashelwa kweminwe bukhoma, okungakhomba iminwe yeminwe yesikhumba, futhi ikhombe izinga lokushisa elicashile kanye nomswakama. Kuqinisekisiwe ukuthi kungubuchwepheshe obuthuthukisiwe obungakhonjwa kuphela ngabantu abaphilayo, futhi bukugweme ukuphepha kokukopisha iminwe ukuze badlule. Izinkinga zobuchwepheshe bezocansi. Ngokwesici sokuqina seminwe yezinto eziphilayo, singagcina iminwe yemvelo yomuntu oneminwe yezinto eziphilayo kusengaphambili. Ngokuqhathanisa iminwe yezinto eziphilayo ngeminwe yeminwe yangaphambi kokulondolozwa kwemvelo, ubunikazi bakhe bangempela bungaqiniswa ngokunembile.
Manje luyini uhlelo lokuhlonza umunwe oluzenzakalelayo? Uhlelo lokuhlonza umunwe oluzenzakalelayo lusebenzisa imishini yokuguqulwa kwe-Photoelectric Conversic kanye nobuchwepheshe bezithombe zekhompyutha ukuqoqa, ukuhlaziya, ukuqhathanisa ukuqhathanisa iminwe ephilayo, futhi kungakwazi ngokuzenzakalelayo, ngokushesha nangokuthi babone ubunikazi bomuntu siqu. Ngokuvamile kungahlukaniswa izingxenye ezimbili: "Ingxenye engaxhunyiwe ku-inthanethi" kanye "nengxenye online". Ingxenye engaxhunyiwe ku-inthanethi ifaka izinyathelo eziphambili zokuqoqa izigxivizo zeminwe ngomqokeleli zeminwe, ukukhipha amaphuzu minutiae, futhi ukonga amaphuzu ku-database ukwakha umtapo wezincwadi wethempulethi yeminwe. Ingxenye ye-inthanethi ifaka ukuqoqa izigxivizo zeminwe ngomqokeleli zeminwe, yakhipha amaphuzu amaminithi, bese iqhathanisa lamaphoyinti amaminithi we-minutiae ngamaphoyinti we-template minplatate agcinwe noma amaphuzu wokufaka we-template minplate aqhamuka kumunwe womunwe ofanayo. Ngemuva kokusebenzisa izindlela zokuqashelwa kwe-PhotoElectric ezithuthukile ukuqoqa imininingwane yeminwe yemvelo, iguqulwe ibe yikhodi engaqhathaniswa nephasiwedi ecutshungulwe yikhompyutha. Lawa makhodi abethelwe bese ekhonjwa futhi ahlulelwe ngama-algorithms akhethekile ahlobene. Amanye ama-algorithms asebenzisa lonke iphethini yomunwe wemvelo, futhi abanye basebenzisa imininingwane ekhethekile yomunwe wezinto eziphilayo.
