Yisiphi isilinganiso sokwenqaba kanye nenani lokuvuma elingamanga lesithwebuli somunwe?

Ngikholwa ukuthi wonke umuntu ujwayelene nesithwebuli somunwe manje, kepha uke wawazwa la magama lapho uthenga isithwebuli somunwe, izinga lokuvuma iminwe, le migomo ekhokhelwayo mayelana nokukhiya kweminwe ngokuvamile ayiqondwa ngabantu abangaqondakali abashibhile. Kodwa-ke, njengoba uzosebenzisa isithwebuli seminwe, ngiphakamisa ukuthi abathengi kufanele baziqonde.

Ake ngikuchazele ukuthi yini izinga lokuphulwa kanye namanga lokubakhona isikhathi sokuqashelwa kweminwe. Izinga lokunqatshelwa kanye nezinga lokuvuma kwamanga livela ekuhlolweni kwe-hypothesis ngombono olungenzeka. Lapho inani lokubona leminwe liliqiniso, amathuba okuthi ahlulelwe njengoba amanga ubude benqatshwa. Lapho inani lokubona leminwe lokuthola iminwe lingamanga, amathuba okuthi ahlulelwe njengeqiniso inani lokuvuma kwamanga.

Ngokwemibandela ka-Lamben, izinga lokudilizwa lisho ukuthi iminwe yeqiniso yomsebenzisi ayikwazi ukuqashelwa, futhi izinga lokuvuma kwamanga lisho ukuthi umunwe wamanga noma umunwe ongasebenzisi umdweshu wenziwe ngephutha njengomunwe weqiniso. Abaphansi la manani amabili, abangcono, futhi futhi bayizisekelo ezibalulekile zokunquma ukuthi umkhiqizo wokuthwebula weminwe ufanelekile.

Izindinganiso zezinga lokwenqatshwa kanye nezinga lokuvuma kwamanga ngaphambili elikhishwe nguMnyango WezokuPhiko Kwe-China yilezi: Izinga lokwenqatshwa kufanele kube ≤3%, futhi izinga lokuvuma kwamanga kufanele libe ≤0.001%. Ngokusho kwamazinga okuphepha kazwelonke afanele, izinga lokuphepha lesithwebuli seminwe seminwe seminyango yokungena ekhaya kufanele ibe sezingeni eli-3. Izinga lezokuphepha 3 lingelona lesilinganiso senqatshwa <0.1%, kanye nenani lokuvuma elingamanga = <0.00001%. Ngakho-ke, ngixwayisa ukuthi ungathengi izingidi zeminwe esezingeni eliphansi ngokushibhile, ngoba abakhiqizi bangadela kuphela izici zokuphepha ukwenza inzuzo ukuze banciphise izindleko.

Ngokuvamile, imingcele emibili yokwenqatshwa kwezinga lokunqatshwa kanye nezinga lokuvuma kwamanga kuhlobene. Uma isithwebuli somunwe sinesilinganiso sokunqatshwa okuphezulu, inani lokwamukela amanga liphansi; Uma izinga lokunqatshwa kwenqatshwa liphansi, inani lokwamukela amanga liphezulu. Lokhu kungubudlelwano obuhlukahlukene. Kodwa-ke, lapho umenzi we-Scanner we-Fingerprint enamandla ethuthukisa ubuciko bayo nobuchwepheshe, lezi zinkomba ezimbili zingancishiswa.
