Isilinganiselo Sokuqashelwa Kwamanga Sokuqashelwa Kweminwe / Ukwenqatshwa Kwezilinganiso

Izinga lokuqashelwa kwamanga / ukwenqatshwa kwamanga kwesithwebuli zeminwe kungenzeki enye yezinkomba ezibaluleke kakhulu zesithwebuli somunwe, esaziwa nangokuthi izinga lokuqashelwa ngamanga kanye ne-rate yokuvuma:

. Noma ngabe kuyi-500DPI noma izinga lokudilika <0.1%, kungumqondo nje wabasebenzisi abajwayelekile, futhi ayikho indlela yokuthola. Isendi Lokuhlola ukuthi izinga lokudilizwa kufanele kube ≤3% futhi isilinganiso sokuqashelwa kwamanga kufanele kube ≤0.001%.
. Lokhu kubonakala kungumqondo wokuhlolwa kwe-hypothesics ku-Mathematics: Ezingeni elifanayo, izinga lokudilizwa kweqiniso liphezulu, inani lokuqashelwa amanga liphansi, futhi okuphambene nalokho. Lokhu kungubudlelwano obuhlukahlukene. Kepha kungani kulungile ngezinga elithile? Ngoba uma inqubo neleveli yezobuchwepheshe ithuthukiswa, lezi zinkomba ezimbili zingancishiswa, ngakho-ke ngokulandelana, izinga lobuchwepheshe lisadingeka ukuthi lithuthukiswe. Ukuze usheshise isitifiketi, abanye abakhiqizi behlisa izinga lokuphepha lapho bechitha ukuphepha ukuze bakha izithombe zamanga ngejubane elisheshayo kanye namakhono okukhomba aqinile. Lokhu kuvela kaningi kukhiye wephasiwedi we-Fingerprint noma izingidi zedemo.
Ngokuya ngamazinga afanele, izinga lokuphepha lesithwebuli somunwe elisetshenziswa ezihlangeni zokungena ekhaya kufanele libe sezingeni lokungena ekhaya
Ukulungiswa kwekhanda leminwe elisetshenzisiwe kusithwebuli somunwe ngu-640 × 480, okuyi-300,000 DPI. Ukunemba kwenzwa yeminwe ye-Optical Fingerprint kungamaphikseli angama-300,000, izinga lokudilizwa li- <0.1
