Ubuchwepheshe bokubona i-iris busekelwe ku-iris esweni ukuze kuqashelwe ubuwena, obusetshenziswa ezindaweni ezinezidingo eziphezulu zobumfihlo. Isakhiwo samehlo omuntu sakhiwe nge-sclera, iris, pupil lens, retina, njll. iris iyingxenye eyisiyingi phakathi komfundi omnyama kanye ne-sclera emhlophe, equkethe amachashazi amaningi ahlotshaniswayo, imicu, imiqhele, imithende, ingemuva, njll Izici zesigaba. Ngaphezu kwalokho, ngemva kokwakhiwa kwe-iris esigabeni sokuthuthukiswa kwengane, izohlala ingashintshiwe kuyo yonke inkambo yokuphila. Lezi zici zinquma ukuhluka kwezici ze-iris nokuqashelwa kobunikazi. Ngakho-ke, isici se-iris seso singathathwa njengento yokuhlonza yomuntu ngamunye.
Ukuqashelwa kwe-iris kufakazelwe ukuthi kungenye yezindlela ezithandwayo zokuqashelwa kwebhayomethrikhi, kodwa imikhawulo yezobuchwepheshe ikhawulela ukusetshenziswa okubanzi kokuqashelwa kwe-iris emabhizinisini nasezindaweni zikahulumeni. Lobu buchwepheshe buncike esithombeni sokucaca okuphezulu esikhiqizwe isistimu ukuze kuhlolwe okunembile, kodwa okokusebenza kokuqaphela iris okuvamile kunzima ukuthwebula isithombe esicacile ngenxa yokujula kwayo kwenkambu okungajulile. Ngaphezu kwalokho, izinhlelo zokusebenza ezidinga isikhathi sokuphendula esisheshayo sokubonwa okukhulu okuqhubekayo azikwazi ukuthembela kumadivayisi ayinkimbinkimbi ngaphandle kwe-autofocus. Ukunqoba le mikhawulo ngokuvamile kwandisa umthamo kanye nezindleko zesistimu.
Imakethe yebhayomethrikhi ye-iris kulindeleke ukuthi ibone ukukhula okunamadijithi amabili ukusuka ku-2017 kuya ku-2024. Lokhu kukhula kulindeleke ukuthi kusheshise ngenxa yesidingo esikhulayo sezixazululo ze-biometric ezingaxhunywanga kubhubhane lwe-covid-19. Ukwengeza, lolu bhubhane selubangele ukwanda kwesidingo sokulandela umkhondo woxhumana nabo kanye nezixazululo zokuhlonza. I-ChuangAn optical lens inikeza isixazululo esingabizi kakhulu nesisezingeni eliphezulu sezinhlelo zokusebenza zokuthwebula izithombe ekuqashelweni kwebhayomethrikhi.
