ʻO ka biometric nā ana kino a me nā helu e pili ana i nā ʻano kanaka. Hoʻohana ʻia ka hōʻoia biometric (a i ʻole ka hōʻoia ʻoiaʻiʻo) i ka ʻepekema kamepiula ma ke ʻano o ka ʻike a me ka mana ʻike. Hoʻohana ʻia ia e ʻike i nā poʻe i loko o nā hui i lalo o ka nānā ʻana.

ʻO nā mea hōʻike biometric nā hiʻohiʻona kūʻokoʻa, hiki ke ana i hoʻohana ʻia e lepili a wehewehe i nā kānaka. Hoʻokaʻawale pinepine ʻia nā ʻike biometric e like me nā hiʻohiʻona physiological e pili ana i ke ʻano o ke kino. Aia nā laʻana, akā ʻaʻole i kaupalena ʻia i ka manamana lima, nā ʻaʻa pāma, ʻike maka, DNA, paʻi pāma, geometry lima, ʻike iris, retina, a me ka ʻala/ʻala.

ʻO ka ʻenehana hōʻike biometric e pili ana i ka ʻepekema lolouila, optics a me acoustics a me nā ʻepekema kino ʻē aʻe, nā ʻepekema biological, biosensors a me nā kumu biostatistics, ʻenehana palekana, a me nā ʻenehana naʻauao a me nā ʻepekema kumu ʻē aʻe a me nā ʻenehana noiʻi hou. He hoʻonā ʻenehana multidisciplinary piha.

I nā makahiki i hala iho nei, me ka hoʻomohala ʻana o ka naʻauao artificial, ua lilo ka ʻenehana ʻike biometric i mea makua. I kēia manawa, ʻo ka ʻenehana ʻike maka ke ʻano o ka biometrics.

ʻIke maka

ʻO ke kaʻina hana o ka ʻike maka ʻo ia 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 AdaBoos algorithm, convolutional neural network a kākoʻo i ka mīkini vector i ke aʻo ʻana i ka mīkini.

ʻO ke kaʻina hana o ka ʻike maka

I kēia manawa, ua hoʻomaikaʻi maikaʻi ʻia nā pilikia o ka ʻike maka maʻamau e like me ka hoʻololi ʻana o ka maka, occlusion, like, etc. 2D alo, 3D alo, multi-spectral alo Loaʻa i kēlā me kēia mode nā hiʻohiʻona hoʻololi hoʻololi ʻokoʻa, ka pae palekana ʻikepili a me ka ʻike pilikino, etc. Hiki iā ia ke hoʻomaopopo koke i ka ʻike o ke kanaka, i lawe mai i kahi holomua no ka hoʻohana ʻana i ka ʻike maka ʻelua.

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

ʻIke ʻana i ka pālima

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

I kēia makahiki, ua hoʻomaka ka hoʻāʻo ʻana o ka ʻenehana ʻike palm o Amazon, ʻo Orville i kapa inoa ʻia. Loaʻa mua ka scanner i 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 hou ʻana o ka lua o nā kiʻi polarized, ua kālele ʻo ia i ka hale pāma a me nā hiʻohiʻona o loko, e like me nā veins, iwi, nā ʻiʻo palupalu, a me nā mea ʻē aʻe. ʻO kēia mau kiʻi i hoʻomālamalama maikaʻi ʻia, i ka nānā ʻana, a hōʻike i ka pāma ma kahi kikoʻī kikoʻī, ma kahi kikoʻī kikoʻī, a ua hōʻailona ʻia ma ke ʻano he lima hema a ʻākau paha.

I kēia manawa, hiki i ka ʻenehana ʻike palmprint o Amazon ke hōʻoia i ka ʻike pilikino a me ka uku piha i loko o 300 milliseconds wale nō, a ʻaʻole koi i nā mea hoʻohana e kau i ko lākou mau lima ma luna o ka hāmeʻa scanning, nalu wale a nānā me ka hoʻopili ʻole. ʻO ka hapa hemahema o kēia ʻenehana ma kahi o 0.0001%. I ka manawa like, ʻo ka ʻike ʻana i ka palmprint he hōʻoia pālua i ka pae mua - ʻo ka manawa mua e loaʻa ai nā hiʻohiʻona o waho, a ʻo ka lua o ka manawa e loaʻa ai nā ʻano hoʻonohonoho kūloko. Hoʻohālikelike ʻia me nā ʻenehana biometric ʻē aʻe e pili ana i ka palekana, hoʻomaikaʻi.

Ma kahi o nā hiʻohiʻona biometric i luna, ua hoʻolaha ʻia ka ʻenehana ʻike iris. ʻO ka haʻahaʻa haʻahaʻa o ka ʻike hoʻopunipuni o ka iris e like me 1/1000000. Hoʻohana nui ia i nā ʻano o ka iris life invariance a me ka ʻokoʻa e ʻike ai i nā ʻike.

I kēia manawa, ʻo ka ʻae ʻana i ka ʻoihana ʻo ka ʻike ʻana i kahi ʻano hoʻokahi he mau bottlenecks i ka hana ʻike a me ka palekana, a ʻo ka hui pū ʻana he mea koʻikoʻi nui i ka ʻike maka a hiki i ka ʻike biometric-ʻaʻole wale ma o ka multi-factor. no ka hoʻomaikaʻi ʻana i ka pololei ʻike hiki ke hoʻomaikaʻi i ka hiki ke hoʻololi i ka hiʻohiʻona a me ka palekana pilikino o ka ʻenehana biometric i kekahi ʻano. Ke hoʻohālikelike ʻia me ka algorithm mode-mode kuʻuna, hiki iā ia ke hoʻokō maikaʻi i ka helu kālā ʻike wahaheʻe (e like me ka haʻahaʻa o ka ʻumi miliona), ʻo ia hoʻi ke ʻano nui o ka hoʻomohala ʻana i ka ʻike biometric.

Pūnaehana biometric multimodal

Hoʻohana nā ʻōnaehana biometric multimodal i nā sensor a i ʻole biometric e lanakila ai i nā palena o nā ʻōnaehana biometric unimodal. ʻOiai ua kaupalena ʻia nā ʻōnaehana biometric unimodal e ka kūpaʻa o ko lākou ʻike, ʻaʻole paha e pilikia kekahi mau ʻōnaehana unimodal i nā palena like. Hiki i nā ʻōnaehana biometric multimodal ke loaʻa nā pūʻulu o ka ʻike mai ka māka hoʻokahi (ʻo ia hoʻi, nā kiʻi he nui o kahi iris, a i ʻole nā ​​hiʻohiʻona o ka manamana lima hoʻokahi) a i ʻole ka ʻike mai nā biometric ʻokoʻa (e koi ana i ka scan manamana lima a, me ka hoʻohana ʻana i ka leo, kahi passcode i ʻōlelo ʻia).

Hiki i nā ʻōnaehana biometric multimodal ke hoʻohui i kēia mau ʻōnaehana unimodal i ka manawa like, i ka hui pū ʻana o ia mau mea, a i ʻole i ka pūʻulu, e pili ana i nā modes sequential, parallel, hierarchical a me serial integration modes.

CHANCCTVua hoʻomohala i ka moʻo onā lens biometricno ka ʻike maka, ka ʻike paʻi lima a me ka ʻike manamana lima a me ka ʻike iris. No ka laʻana, ʻo CH3659A kahi lens distortion haʻahaʻa 4k i hoʻolālā ʻia no nā ʻike 1/1.8''. Hōʻike ia i nā aniani a me nā hoʻolālā paʻa me 11.95mm TTL wale nō. Hoʻopaʻa ʻo ia i 44 degere ākea ākea. He kūpono kēia lens no ka ʻike paʻi lima.
