Isazisi sokuchukumisa ligama le isivamvo somnwe sokuchongwa kwe-Apple. Yinto ekuvumela ngoku ukungqinisisa ukuvula ii-iPhone 5 zakho kunye nokugunyazisa i-iTunes kunye neVenkile ye App ukuba ithenge kwiakhawunti yakho.
Nge-iOS 8, iApple iphuhlise isinxulumanisi senkqubo yekhompyutha (API) ziyafumaneka kubaphuhlisi, ke yonke into esuka kumphathi wegama eligqithisiweyo ukuya kwinkonzo yebhanki kwindawo yokufihla iifoto yabucala inokukhuseleka kwaye ilunge. Kodwa iza kusebenza njani?
Ukusebenza
Xa ubeka umnwe kwiTouch ID, Isangqa sentsimbi esingqongileyo sibona amandla kunye nesenzi esenziweyo. Ifoto enesisombululo esiphakamileyo somnwe yenziwe, yaguqulwa yenziwa imbonakalo yemathematics, kwaye yathunyelwa ngonxibelelwano olunentambo kwi-chip ye-A7 ekhuselekileyo. Ukuba idatha ayihambelani, uphawu "hayi" luyakhutshwa kwaye kufuneka uzame kwakhona, okanye ufake ipassword. Ukuba idatha iyahambelana, kukhutshwa uphawu "ewe" ukuvulwa okugunyazisiweyo okanye ezivenkileni.
Le nkqubo waya kuhlala ngo-2013 nge-iOS 7 kunye ne-iPhone 5s. Ngelo xesha akukho API yayikhutshelwe abaphuhlisi, ukusetyenziswa kweempawu zokuchukumisa isazisi zazithintelwe ukuba zisetyenziswe yiApple. Kucingelwa ukuba iApple ibingenalo ixesha lokwakha indawo ekhuselekileyo ukukhupha eli nqaku.
Ngo-2014 nango-iOS 8 ukhuseleko lusekwe kwitshixo nakwisakhelo esitsha esibizwa ngokuba kukuQinisekiswa kweNdawo. Le keychain yindawo yogcino ekhuselekileyo ka-Apple yamaphasiwedi aqala ukusetyenziswa kwi-Mac de yanwenwela kwi-iOS nakwi-iCloud. Kwi-iOS 8, sisitshixo apho ifumana khona umqondiso ka "ewe" okanye "hayi" kwaye ikwasisixhobo esingundoqo esinikezela okanye esibamba iziqinisekiso zezicelo.
Chukumisa i-ID yabaphuhlisi
Nge-iOS 8, iApple yazisa Uluhlu lolawulo lwendawo yokufikelela (ACL) yokufikelela kunye nokuqinisekiswa. Ngabo, abaphuhlisi banokuseka xa kukho into ephambili yesitshixo, kunye nokwenzekayo xa kufikelelwa.
Ukufikeleleka kuyafana Chukumisa i-ID njengoko kunjalo ngekhodi yokudlula, ukuba isixhobo sivuliwe. Ukuqinisekiswa kukutsha kwaye kufuna imigaqo yokujonga ukuba yeyiphi na imeko ekufuneka kuhlangatyezwane nayo I-keychain inikeza ulwazi kwisicelo.
I-ID yokuChukumisa ihamba phambili ngaphezulu kwekhowudi yokufikelela, xa ifumaneka, kuba iyakhawuleza kwaye ilula kunokufikelela ngentambo yamanani okanye abalinganiswa bealfanumeric.
Abaphuhlisi kunye nokusetyenziswa kwabo Zuza njengelifa inkqubo efanayo yokhuseleko kwiTouch IDOko kuthetha ukuba:
- ukuba isazisi sokuchukumisa asiqinisekisi emva iinzame ezine,
- ukuba isixhobo sikhona qalisa kwakhonat
- Ukuba i-ID yeTouch ayisetyenziswanga kwi Iiyure ezingama-48,
Emva koko indawo ekhuselekileyo iya kwenziwa ingasebenzi kwaye ikhowudi yofikelelo iya kufuneka ukuyinika amandla kwakhona.
Ukulungelelanisa ne-API entsha, iApple ibonelela nge- ujongano olutsha lokuphatha ukuthengiselana usebenzisa i-ID yesiphatho kwizicelo zeVenkile ye App. I-Apple iya kuzisa igama lesicelo kwibhokisi yencoko yababini, ukuze uhlale uyazi ukuba ngubani ocela ubungqina, abaphuhlisi ukukhuthaza ukongeza umtya wokubhaliweyo owongezelelweyo Chaza ukuba kutheni becela ubunyani.
Kwelinye icala, abaphuhlisi bayakhuthazwa ukuba sukujonga rhoqo, apho iApple ikwabonelela nge «imo yokungqinisisa»Ke abaphuhlisi banako cima ujongano kwaye yazisa ngokulula ukuba ngaba bafuna ngokwenene ukuthenga ezi zinto, ubunyani buyakufuneka.
Izandiso
Ukongeza kwizicelo, Isazisi sokuchukumisa sinokudityaniswa kwizandiso. Ke, umzekelo, isicelo somphathi wegama eligqithisiweyo singasebenzisa i-ID yokuChukumisa ukungqinisisa ngaphambi kokubonisa amagama okugqitha ngaphakathi kwesicelo sawo.
Omnye ulwandiso olulawula ipassword, como 1Password, podría ser llamada desde dentro de Safari y permitir a Touch ID que autentique, por lo que la extensión puede gcwalisa ngokuzenzekelayo imihlaba yegama eligqithisiweyo.
Chukumisa ukhuseleko lwe-ID ye-ID
Ujongano lokuchukumisa lukhona Iphethwe kwaye ilawulwa yi-iOS, hayi ngokusetyenziswa kweVenkile yeApple oyilawulayo. Kuphela kusemva kokuba kungafunyanwa ulawulo kwakhona.
Kwakhona, ngenxa yezizathu zokhuseleko, I-Apple kunye ne-iCloud azixhasi izinto ezikhuselweyo ze-ACL, kwaye sukuvumelanisa phakathi kwezixhobo. Ngamanye amagama, idatha ayinakuze ikwi-Intanethi okanye kwiiseva zomntu, kubandakanya neApple.
Abaphuhlisi ngekhe bakwazi ukufikelela kwidatha yeminwe yakho ngokusebenzisa izicelo zabo. Yonke into ihlala ifihliwe ngokukhuselekileyo kwi-enclave ekhuselekileyo.
