ʻO nā biometrics nā ana o ke kino a me nā helu e pili ana i nā ʻano kanaka. Hoʻohana ʻia ka hōʻoia biometric (a i ʻole ka hōʻoia maoli) i ka ʻepekema kamepiula ma ke ʻano he ʻano o ka ʻike a me ka kaohi komo. Hoʻohana ʻia nō hoʻi ia e ʻike i nā kānaka i loko o nā hui e kiaʻi ʻia ana.

ʻO nā mea hōʻike biometric nā ʻano ʻokoʻa a hiki ke ana ʻia i hoʻohana ʻia e lepili a wehewehe i nā kānaka. Hoʻokaʻawale pinepine ʻia nā mea hōʻike biometric ma ke ʻano he mau ʻano physiological e pili ana i ke ʻano o ke kino. ʻO nā laʻana e komo pū ana, akā ʻaʻole i kaupalena ʻia i ka manamana lima, nā aʻa o ka pāma, ka ʻike maka, DNA, ka paʻi pāma, ke ʻano lima, ka ʻike iris, ka retina, a me ke ʻala/ʻala.

ʻO ka ʻenehana ʻike biometric e pili ana i ka ʻepekema kamepiula, optics a me acoustics a me nā ʻepekema kino ʻē aʻe, nā ʻepekema olaola, nā biosensors a me nā kumumanaʻo biostatistics, ʻenehana palekana, a me ka ʻenehana naʻauao hana a me nā ʻepekema kumu ʻē aʻe a me nā ʻenehana noi hou. He hopena loea multidisciplinary piha ia.

I nā makahiki i hala iho nei, me ka hoʻomohala ʻana o ka naʻauao hana, ua lilo ka ʻenehana ʻike biometric i ʻoi aku ka oʻo. I kēia manawa, ʻo ka ʻenehana ʻike maka ka mea hōʻike nui loa o nā biometrics.

ʻIke maka

ʻO ke kaʻina hana o ka ʻike maka e komo pū ana me ka hōʻiliʻili maka, ka ʻike maka, ka unuhi ʻana i nā hiʻohiʻona maka a me ka ʻike hoʻohālikelike maka. Hoʻohana ke kaʻina hana ʻike maka i nā ʻenehana like ʻole e like me ka algorithm AdaBoos, ka pūnaewele neural convolutional a me ka mīkini vector kākoʻo i ke aʻo ʻana i ka mīkini.

Ke kaʻina hana o ka ʻike maka

I kēia manawa, ua hoʻomaikaʻi nui ʻia nā pilikia ʻike maka kuʻuna e like me ka hoʻohuli ʻana o ka maka, ka occlusion, ka like ʻana, a me nā mea ʻē aʻe, kahi e hoʻomaikaʻi nui ai i ka pololei o ka ʻike maka. Maka 2D, maka 3D, maka multi-spectral Loaʻa i kēlā me kēia ʻano nā hiʻohiʻona hoʻololi loaʻa, ke kekelē palekana ʻikepili a me ka ʻike pilikino, a me nā mea ʻē aʻe, a me ka hoʻohui ʻana o ke aʻo hohonu o ka ʻikepili nui e hoʻohui ai ka algorithm ʻike maka 3D i nā hemahema o ka projection 2D, hiki iā ia ke ʻike koke i ka ʻike o ke kanaka, kahi i lawe mai ai i kahi holomua no ka hoʻohana ʻana o ka ʻike maka ʻelua-dimensional.

I ka manawa like, ke hoʻohana ʻia nei ka ʻenehana ʻike biometric i kēia manawa ma ke ʻano he ʻenehana koʻikoʻi e hoʻomaikaʻi i ka palekana o ka ʻike maka, hiki ke pale aku i ka hoʻopunipuni hoʻopunipuni e like me nā kiʻi, nā wikiō, nā hiʻohiʻona 3D, a me nā pale maka prosthetic, a hoʻoholo kūʻokoʻa i ka ʻike o nā mea hoʻohana e hana ana. I kēia manawa, me ka wikiwiki o ka hoʻomohala ʻana o ka ʻenehana ʻike maka, ua lilo nā noi hou he nui e like me nā polokalamu akamai, ke kālā pūnaewele, a me ka uku maka i mea kaulana, e lawe mai ana i ka wikiwiki a me ka maʻalahi i ke ola a me ka hana o kēlā me kēia kanaka.

Ka ʻike ʻana i ka paʻi lima

ʻO ka ʻike ʻana i ka palmprint kahi ʻano hou o ka ʻenehana ʻike biometric, kahi e hoʻohana ai i ka palmprint o ke kino kanaka ma ke ʻano he hiʻohiʻona pahuhopu, a hōʻiliʻili i ka ʻike olaola ma o ka ʻenehana kiʻi multispectral. Hiki ke manaʻo ʻia ka ʻike ʻana i ka palmprint multi-spectral he kumu hoʻohālike o ka ʻenehana ʻike biometric e hoʻohui i ka multi-modality a me nā hiʻohiʻona pahuhopu he nui. Hoʻohui kēia ʻenehana hou i nā hiʻohiʻona ʻike ʻekolu o ka spectrum ʻili, ka palmprint a me nā veins vein e hāʻawi i ka ʻike nui aʻe i ka manawa hoʻokahi a hoʻonui i ka ʻokoʻa o nā hiʻohiʻona pahuhopu.

I kēia makahiki, ua hoʻomaka ka hoʻāʻo ʻana i ka ʻenehana ʻike pāma a Amazon, i kapa inoa ʻia ʻo Orville. Loaʻa mua i ka scanner kahi hoʻonohonoho o nā kiʻi kumu polarized infrared, e kālele ana i nā hiʻohiʻona o waho o ka pāma, e like me nā laina a me nā pelu; i ka loaʻa ʻana o ka lua o ka hoʻonohonoho o nā kiʻi polarized hou, kālele ia i ke ʻano o ka pāma a me nā hiʻohiʻona o loko, e like me nā aa koko, nā iwi, nā ʻiʻo palupalu, a pēlā aku. Hoʻoponopono mua ʻia nā kiʻi maka e hāʻawi i kahi hoʻonohonoho o nā kiʻi e loaʻa ana nā lima. Hoʻomālamalama maikaʻi ʻia kēia mau kiʻi, i ka nānā ʻana, a hōʻike i ka pāma i kahi kuhikuhi kikoʻī, ma kahi kūlana kikoʻī, a kapa ʻia he lima hema a ʻākau paha.

I kēia manawa, hiki i ka ʻenehana ʻike palmprint a Amazon ke hōʻoia i ka ʻike pilikino a hoʻopau i ka uku i loko o 300 milliseconds wale nō, a ʻaʻole koi i nā mea hoʻohana e kau i ko lākou mau lima ma ka hāmeʻa scan, e peahi wale a scan me ka ʻole o ka hoʻopā. ʻO ka helu hāʻule ʻole o kēia ʻenehana ma kahi o 0.0001%. I ka manawa like, ʻo ka ʻike palmprint he hōʻoia pālua ia i ka pae mua - ʻo ka manawa mua e loaʻa ai nā ʻano o waho, a ʻo ka lua o ka manawa e loaʻa ai nā ʻano o ka hui kūloko. Hoʻohālikelike ʻia me nā ʻenehana biometric ʻē aʻe ma ke ʻano o ka palekana, ua hoʻomaikaʻi ʻia.

Ma waho aʻe o nā hiʻohiʻona biometric i luna, ke hoʻolaha nui ʻia nei ka ʻenehana ʻike iris. ʻO ka helu ʻike wahaheʻe o ka ʻike iris he haʻahaʻa ia e like me 1/1000000. Hoʻohana nui ia i nā ʻano o ka invariance ola iris a me ka ʻokoʻa e ʻike ai i nā ʻike.

I kēia manawa, ʻo ka manaʻo like ma ka ʻoihana, ʻo ka ʻike ʻana i hoʻokahi ʻano he mau pilikia i ka hana ʻike a me ka palekana, a ʻo ka hui multi-modal kahi holomua nui i ka ʻike maka a me ka ʻike biometric—ʻaʻole wale ma o ka multi-factor. ʻO ke ala e hoʻomaikaʻi ai i ka pololei o ka ʻike hiki ke hoʻomaikaʻi i ka hoʻololi ʻana i ke kahua a me ka palekana pilikino o ka ʻenehana biometric i kekahi ʻano. Ke hoʻohālikelike ʻia me ka algorithm single-mode kuʻuna, hiki iā ia ke hoʻokō maikaʻi i ka helu ʻike wahaheʻe pae kālā (e like me hoʻokahi i loko o ka ʻumi miliona), ʻo ia hoʻi ke ʻano nui o ka hoʻomohala ʻana o ka ʻike biometric.

ʻŌnaehana biometric multimodal

Hoʻohana nā ʻōnaehana biometric multimodal i nā sensor he nui a i ʻole biometrics e lanakila ai i nā palena o nā ʻōnaehana biometric unimodal. No ka laʻana, hiki ke hoʻopilikia ʻia nā ʻōnaehana ʻike iris e nā iris ʻelemakule a hiki ke hoʻonui ʻia ka ʻike manamana lima uila e nā manamana lima i pau a ʻoki ʻia paha. ʻOiai ua kaupalena ʻia nā ʻōnaehana biometric unimodal e ka pono o kā lākou mea hōʻike, ʻaʻole paha e ʻeha kekahi mau ʻōnaehana unimodal i nā palena like. Hiki i nā ʻōnaehana biometric multimodal ke loaʻa nā ʻikepili mai ka māka like (ʻo ia hoʻi, nā kiʻi he nui o kahi iris, a i ʻole nā ​​​​scan o ka manamana lima like) a i ʻole ka ʻikepili mai nā biometrics like ʻole (e koi ana i nā scan manamana lima a, me ka hoʻohana ʻana i ka ʻike leo, kahi passcode i ʻōlelo ʻia).

Hiki i nā ʻōnaehana biometric multimodal ke hoʻohui i kēia mau ʻōnaehana unimodal ma ke ʻano he hoʻokahi, i ka manawa like, kahi hui pū ʻana o ia mau mea, a i ʻole ma ke ʻano he moʻo, e pili ana i nā ʻano hoʻohui sequential, parallel, hierarchical a me serial.

CHANCCTVua hoʻomohala i kahi moʻo onā aniani biometricno ka ʻike maka, ka ʻike ʻana i ka manamana lima a me ka ʻike ʻana i ka manamana lima a me ka ʻike ʻana i ka iris. No ka laʻana, ʻo CH3659A kahi aniani hoʻohaʻahaʻa haʻahaʻa 4k i hoʻolālā ʻia no nā mea ʻike 1/1.8 ''. Loaʻa iā ia nā aniani āpau a me nā hoʻolālā liʻiliʻi me 11.95mm TTL wale nō. Hopu ia i ke kahua ʻike ākea 44 degere. He kūpono kēia aniani no ka ʻike ʻana i ka manamana lima.
