Ama-biometric ayizilinganiso zomzimba nokubalwa okuhlobene nezimpawu zomuntu. Ukuqinisekiswa kwe-biometric (noma ubuqiniso obungokoqobo) kusetshenziswa kwisayensi yekhompyutha njengendlela yokuhlonza nokulawula ukufinyelela. Kusetshenziselwa futhi ukukhomba abantu ngamaqembu abhekwa.

Izikhombi ze-biometric yizici ezihlukile, ezilinganisekayo ezisetshenziselwa ukulebula nokuchaza abantu. Izikhombi ze-biometric zivame ukuhlukaniswa njengezimpawu zomzimba ezihlobene nokwakheka komzimba. Izibonelo zifaka, kepha azikhawulwanga ku-zeminwe zeminwe, ukuqashelwa kobuso, ukuqashelwa kobuso, i-DNA, ukuphrinta kwesundu, i-geometry yesandla, ukuqashelwa kwe-Irina, iphunga.

Ubuchwepheshe bokuhlonza biometric bubandakanya isayensi ye-computer, i-Optics nama-acoustics nezinye izinto zesayensi engokomzimba, izinkomba zemvelo, ama-biosensors kanye nobuchwepheshe bezobuchwepheshe bokufakelwa kanye nezinye izinto zokufakelwa kanye nobuchwepheshe obuningi besicelo kanye nobuchwepheshe obuningi bohlelo lokusebenza. Kuyisixazululo sezobuchwepheshe esiphelele sezobuchwepheshe.

Eminyakeni yamuva nje, ngokuthuthukiswa kobuhlakani bokufakelwa, ubuchwepheshe bokuhlonza biometric buvuthiwe ngokwengeziwe. Njengamanje, ubuchwepheshe bokuqashelwa ubuso bungukumele kakhulu kwama-biometric.

Ukuqashelwa kobuso

Inqubo yokuqashelwa kobuso ifaka ukuqoqwa kobuso, ukutholwa kobuso, ukukhishwa kwesici sobuso kanye nokuqashelwa kobuso. Inqubo yokuqashelwa kobuso isebenzisa ubuchwepheshe obuhlukahlukene obufana ne-Adaboos algorithm, inethiwekhi ye-Neaural Neaural Network and Support Vector ekufundeni komshini.

Inqubo yokuqashelwa kobuso

Njengamanje, ubunzima bokuqashelwa kobuso bendabuko kufaka phakathi ukujikeleza kobuso, i-occlusion, ukufana, njll. Bethuthuke kakhulu, okuthuthukisa kakhulu ukunemba kokuqashelwa kobuso. Ubuso be-2D, ubuso be-3D, ubuso obuningi obubhekelayo Imodi ngayinye inezimo ezahlukahlukene zokutholwa kwezimo, iziqu zokuphepha zedatha nokuzwela okujulile kwe-algorithm ye-BIG yenza iphutha le-2D Projection of 2d Projection, Ingakhomba ngokushesha ubunikazi bomuntu, obulethe ukuphumelela okuthile kokusetshenziswa kokwamukelwa kobuso obunezinhlangothi ezimbili.

Ngasikhathi sinye, ubuchwepheshe bokutholwa kwe-biometric njengamanje busetshenziswa njengobuchwepheshe obuhle ukwenza ngcono ukuphepha kokuqashelwa kobuso, okungamelana ngempumelelo inkohliso yokukhohlisa njengezithombe, amavidiyo, amamodeli we-3D, kanye nokuzimela ukunquma ukuthi ungubani abasebenzisi abasebenzayo. Njengamanje, ngokuthuthukiswa okusheshayo kobuchwepheshe bokuqashelwa kobuso, izinhlelo eziningi ezintsha ezifana namadivayisi ahlakaniphile, ezezimali eziku-inthanethi, kanye nokukhokha kobuso sekuye kwathandwa ngokwengeziwe, okuletha ijubane futhi kube lula empilweni yawo wonke umuntu.

Ukuqashelwa kwe-Palmprint

Ukuqashelwa kwe-Palmprint kuwuhlobo olusha lobuchwepheshe bokuqashelwa kwe-biometric, obusebenzisa i-Palmprint yomzimba womuntu njengesici esiqondiwe, futhi iqoqa imininingwane yemvelo ngokusebenzisa ubuchwepheshe bokucabanga nge-multispectral. Ukuqashelwa kwe-Palm-spectral Palmpral kungathathwa njengemodeli yobuchwepheshe bokuqashelwa kwe-biometric okuhlanganisa ukulingana okuningi kanye nezici eziqondiwe eziningi. Lokhu kubuchwepheshe okusha kuhlanganisa izici ezintathu ezikhonjwayo zesikhumba spectrum, ukuphrinta kwesundu kanye nemithambo yethambo ukuhlinzeka ngemininingwane eminingi ngasikhathi sinye futhi kwandise ukwahlukanisa kwezici eziqondiwe.

Kulonyaka, ubuchwepheshe bokuqashelwa kwesundu, okuthiwa yi-Orville, uqalile ukuhlola. Isithwebuli sokuqala sithola isethi yezithombe zangempela ze-infrared ezinama-polarised, zigxile ezicini zangaphandle zesandla, ezinjengemigqa namaqhubu; Lapho uthola isethi yesibili yezithombe ezinama-polarised futhi, igxile ekwakhiweni kwangaphakathi kanye nezici zangaphakathi, amathambo, izicubu ezithambile, njll. Izithombe eziluhlaza zisetshenzisiwe ukuhlinzeka ngesethi yezithombe eziqukethe izandla. Lezi zithombe zikhanyiswe kahle, zigxile kakhulu, futhi zikhombise intende ngokulandelana okuthile, endaweni ethile, futhi yabhalwa njengesobunxele noma kwesokudla.

Njengamanje, ubuchwepheshe bokuqashelwa kwe-Amazon bungaqinisekisa ubunikazi bomuntu siqu nokukhokha ngokuphelele ngama-millisecond angama-300 kuphela, futhi akudingi ukuthi abasebenzisi basebenzise izandla zabo kudivayisi yokuskena, bavele baskena ngaphandle kokuxhumana ngaphandle kokuxhumana. Izinga lokuhluleka kwalobu buchwepheshe licishe libe ngu-0.0001%. Ngasikhathi sinye, ukuqashelwa kwe-Palmprint kungukuqinisekiswa okuphindwe kabili esigabeni sokuqala - okokuqala ngqa ukuthola izici zangaphandle, kanti okwesibili ukuthola izici zenhlangano zangaphakathi. Qhathanisa nobunye ubuchwepheshe be-biometric maqondana nokuphepha, ngcono.

Ngaphezu kwezici ze-biometric ezingenhla, ubuchwepheshe bokubona i-Iris buyaziwa futhi. Izinga lokuqashelwa kwamanga lokuqashelwa kwe-IRIS liphansi njenge-1/110000. Isebenzisa kakhulu izici ze-IRIS Life Infrarunce nomehluko ukukhomba ubunikazi.

Njengamanje, ukuvumelana embonini ukuthi ukuqashelwa kokukodwa kunamabhodlela ekusebenzeni kokuqashelwa kanye nokuphepha, kanye nokuqashelwa kwe-biometric - nokuqashelwa kwe-biometric-hhayi kuphela nge-multi-factor indlela Ukwenza ngcono ukunemba kokuqashelwa kungathuthukisa futhi ukuguquguquka kwesigameko kanye nokuphepha kobumfihlo kobuchwepheshe be-biometric ngezinga elithile. Uma kuqhathaniswa ne-algorithm yendabuko eyodwa, kungahlangabezana kangcono nezinga lokuqashelwa kwamanga kwezimali (kuphansi njengelinye kwezigidi eziyishumi), okubuye kube umkhuba omkhulu wokuthuthuka kokuhlonza biometric.

Uhlelo lwe-biometric ye-multimodal

Izinhlelo ze-biometric ze-multimodal zisebenzisa izinzwa eziningi noma ama-biometric ukunqoba ukulinganiselwa kwezinhlelo ze-biometric ezinganqunyelwe.I-ke, ukubonwa kwezinhlelo zokuqashelwa kwe-Iris kungabiswa yiminwe yokuguga kanye nokuqashelwa kweminwe kagesi kungabiswa ngeminwe yokuguga noma yokusika. Ngenkathi izinhlelo ze-biometric ezingenamkhawulo zilinganiselwe ngobuqotho besikhombi sazo, akunakwenzeka ukuthi izinhlelo ezimbalwa ezingafakwanga zihlaselwe ukulinganiselwa okufanayo. Izinhlelo ze-biometric ze-miltimodal zingathola amasethi wolwazi kusuka kumamaki afanayo (okusho, izithombe eziningi ze-IRIS, noma ukuskena komunwe ofanayo) noma imininingwane evela kuma-biometric ahlukene (edinga ukuqashelwa ngezwi, iphasikhodi ekhulumayo).

Izinhlelo ze-biometric ze-miltimodal zingafaka lezi zinhlelo ezingezinhle ngokulandelana, ngasikhathi sinye, inhlanganisela yazo, noma ochungechungeni izindlela zokuhlanganisa ngokulandelana, okuhambisana nalo.

IChancCcccvithuthukise uchungechunge lweama-biometric lensUkuqashelwa kobuso, ukuqashelwa kwe-Palmprint kanye nokuhlonza iminwe kanye nokukhonjwa kwe-IRIS Ifaka yonke ingilazi nemiklamo ecwebile nge-11.95mm TTL. Ithwebula insimu engu-44 degrees evundlile yokubuka. Le lens ilungele ukuqashelwa kwe-Palmprint.
