Zisebenza kanjani izikena zeminwe

I-Fingerprint Receip Straition uhlelo lokuqashelwa kwephethini olujwayelekile, kufaka phakathi amamojula afana nokutholwa kwezithombe zeminwe, ukucubungula, ukukhishwa kwesici nokuqhathanisa. Ukutholwa kwezithombe zeminwe: Izithombe zeminwe ebukhoma zingaqoqwa ngokusebenzisa umqoqi okhethekile weminwe. Njengamanje, abaqoqi bezigxivini zeminwe ikakhulu bafaka phakathi okuphilayo okubonakalayo, i-capacison kanye nengcindezelo ebucayi. Ngezinkomba zezobuchwepheshe ezinjengendawo yokulungiswa nendawo yokutholwa, imboni yezokuphepha yomphakathi yakha amazinga aphesheya kanye nasekhaya, kepha kusekhona ukuntuleka kwezindinganiso ezihlanganisiwe zabanye. Ngokusho kwendawo yeminwe eqoqiwe, ingahlukaniswa ngokuhlukaniswa ngeminwe yeminwe neminwe. Imboni yezokuphepha yomphakathi ngokuvamile isebenzisa iminwe yokugibela. Ngaphezu kwalokho, isithombe somunwe singatholakala ngesithwebuli, ikhamera yedijithali, nokunye okunjalo. Ukucindezelwa kwezithombe zeminwe: Imininingwane yeminwe emikhulu kufanele igcinwe ngemuva kokucindezela ukunciphisa isikhala sokugcina. Izindlela eziphambili zifaka i-JPEG, i-WSQ, ezw, njll.

Isizukulwane sokuqala sokwamukelwa kweminwe kanye nokubakhona kwesizukulwane sokuqala sokwamukelwa kweminwe nokubakhona kwesizukulwane sokuqala sokwamukelwa kweminwe nokubakhona kwesizukulwane sokuqala sokwamukelwa kweminwe nokubakhona kwaziwa kahle. Eminyakeni emibili edlule, ezinye izinhlobo zamabhuku okubhalwe zisebenzisa izikena zeminwe ukuze ziqinisekiswe umazisi lapho abasebenzisi bengena ngaphakathi. Ngokwesitatimende samanje, kufanele kube ngesekhova lokuqala lezikena zeminwe. I-Optical Fingerpring Isikhathi Strance Strance singakwazi ukuskena kuphela ingaphezulu lesikhumba somunwe, noma skena ungqimba lwesikhumba esifile, kepha asikwazi ukuya ku-dermis ngoba ukukhanya kungangeni engxenyeni engaphezulu yesikhumba (isendlalelo sesikhumba esifile). Kulokhu, ukuhlanzeka komunwe kuthinta ngqo umphumela wokuqashelwa. Uma kunothuli oluningi eminweni yomsebenzisi, kungenzeka amaphutha wokubona. Ngaphezu kwalokho, uma abantu benza imodeli yesandla seminwe ngokuya ngeminwe yabo, bangase futhi baphumelele uhlelo lokuhlonza. Kwabasebenzisi, akuphephile kakhulu futhi uzinzile ongalusebenzisa. Isizukulwane sesibili sezinzwa ze-capaciative, isizukulwane sesibili sezinzwa ze-capaciaritive, isizukulwane sesibili sezinzwa ze-capacitive, isizukulwane sesibili sezinzwa ze-capacitive, ubuchwepheshe bezinzwa ze-capacive, ubuchwepheshe bezinzwa ehambisana ne-capacitive, ubuchwepheshe bezinzwa ezihambisanayo Ibhodi, Ukushintshana Plate
Izinzwa zesizukulwane sesizukulwane sesibili zithatha isimo samapuleti amabili e-capacive, futhi izigodi kanye nezigodi zeminwe ziba yi-dielectric phakathi kwamapuleti. I-sensor ibona izinguquko ku-dielectric njalo phakathi kwalaba bobabili ukukhiqiza isithombe somunwe. Kodwa-ke, njengoba ingaphezulu le-sensor lenziwa ngezinto ezisetshenziswayo ze-silicon, kulula ukulimaza, okuholela ekutholeni impilo yenkonzo, futhi kwakha isithombe somunwe ngezigodi kanye neminwe yomunwe ngeminwe, manzi Iminwe, njll. Iphansi.
Isithwebuli somunwe wesizukulwane sesithathu se-bio-RF senziwe manje. Ubuchwepheshe bezinzwa ze-RF bakhipha inani elincane lezimpawu ze-RF ngenhloso ngokwalo, lingena engxenyeni yesikhumba yomunwe ukulawula ukuthungwa kwesithombe sangaphakathi ukuthola isithombe esihle seminwe ukuthola isithombe esihle seminwe ukuthola isithombe esihle seminwe ukuthola isithombe esihle seminwe ukuthola isithombe esihle seminwe ukuthola isithombe esihle seminwe ukuthola umfanekiso omuhle kakhulu. Ngakho-ke, ngeminwe eyomile, i-han`s` asffleast Isizukulwane se-biological radio frequency sensor iminwe, iminwe eyomile neminye iminwe enzima ingadlula kuze kube ngu-99 Ukuxazulula inkinga yeminwe yokufakelwa, ububanzi bokushisa obubanzi: Ilungele izindawo ezibanda kakhulu noma ezishisa kakhulu. Ngoba izinzwa ze-RF zikhiqiza izithombe ezisezingeni eliphakeme, ubuchwepheshe be-RF buyisisombululo esithembeke kakhulu nesiqine kakhulu. Ngaphezu kwalokhu, ikhwalithi ephezulu yesithombe ivumela inzwa ukuthi incishiswe ngaphandle kokudela ukuthembeka kokuqinisekiswa, ngaleyo ndlela kunciphisa izindleko futhi kunika amandla ukusetshenziswa kwenkambu kanye nosayizi abacindezelwe.
