Biometrics yog ntsuas lub cev thiab kev laij cov cai uas muaj feem xyuam rau tib neeg cov yam ntxwv. Biometric authentication (los yog tiag tiag authentication) yog siv hauv computer science raws li ib daim ntawv ntawm kev txheeb xyuas thiab tswj tau. Nws tseem siv los txheeb xyuas cov tib neeg hauv cov pab pawg uas muaj kev soj ntsuam.

Biometric cov cim yog qhov txawv txav, ntsuas cov yam ntxwv tau siv los sau npe thiab piav qhia cov tib neeg. Biometric naj npawb feem ntau categorized ua cov yam ntxwv physiological uas cuam tshuam nrog cov duab ntawm lub cev. Piv txwv li cov piv txwv suav nrog, tab sis tsis muaj cai rau cov ntiv tes, DNA geometry, retina, thiab ntxhiab / ntxhiab / ntxhiab.

Cov thev naus laus zis biometric muaj cov ntsiab lus siv computer, cov ntsiab lus roj ntsha, thiab lwm yam kev paub txog biostatics, thiab cov kev tshawb fawb biostatics thiab ntau yam yooj yim science thiab kev thov siv thev naus laus zis tshiab. Nws yog ib qho kev ua tiav ntau txoj kev daws teeb meem.

Nyob rau hauv xyoo tsis ntev los no, nrog rau kev txhim kho kev txawj ntse cov thev naus laus zis tau dhau los ua neeg paub tab. Tam sim no, kev lees paub thev naus laus zis yog cov neeg sawv cev tshaj plaws ntawm biometrics.

Ntsej muag pom

Cov txheej txheem ntawm kev paub txog ntsej muag muaj xws li kev sib sau lub ntsej muag, kev pom tau ntsej muag, ntsib cov kev lees paub thiab ntsej muag sib txuam. Lub ntsej muag tau lees paub cov txheej txheem siv ntau yam thev naus laus zis xws li adaboos algorithm, convelation neural network thiab txhawb vector tshuab hauv tshuab kev kawm.

Cov txheej txheem ntawm kev paub txog ntsej muag

Tam sim no, lub ntsej muag ib txwm muaj xws li kev sib hloov kev sib hloov, occlusion, zoo sib xws, uas tau zoo dua txhim kho qhov tseeb ntawm lub ntsej muag pom. Lub ntsej muag 2D, 3D ntsej muag, ntau hom kev kawm tau zoo, thiab lwm yam. Nws tuaj yeem txheeb xyuas qhov tseeb ntawm tus kheej ntawm tus neeg, uas tau coj qee qhov kev sib tw rau daim ntawv thov ob-seem tim ntsej muag.

Nyob rau tib lub sijhawm, cov kev tshawb xyuas biometric tau siv los txhim kho kev ruaj ntseg ntawm lub ntsej muag paub, uas tuaj yeem tiv thaiv cov ntsej muag ntsej muag, cov qauv 3D, thiab tus kheej txiav txim siab tus kheej ntawm Cov neeg siv kev khiav haujlwm. Tam sim no, nrog txoj kev loj hlob sai ntawm lub ntsej muag thev naus laus zis, ntau cov ntawv thov kev hloov pauv, kev them nyiaj hauv online, coj tau nrawm thiab yooj yim rau txhua tus neeg lub neej thiab ua haujlwm.

Tsev Nkaug Allentition

Palmin lees paub yog ib hom tshiab ntawm cov kev paub txog biometric lees paub, uas siv tib neeg lub cev ua cov ntaub ntawv ntsig txog kev siv thev naus laus zis. Multi-Spectral Palminct tau lees paub tias yog tus qauv ntawm biometric lees paub cov thev naus laus zis uas ua ke ntau yam qauv. Cov thev naus laus zis tshiab no sib xyaw ua ke ntawm peb tus kheej cov khoom ntiag tug ntawm cov tawv nqaij, paim los yog cov ntaub ntawv ntxiv rau ib zaug thiab nce cov lus txawv ntawm cov hom phiaj.

Xyoo no, Amazon lub caj npab lees paub thev naus laus zis, lej-npe Orville, tau pib kuaj. Lub scanner thawj kis tau ib txheej ntawm infrared polarized cov duab qub, tsom mus rau sab nraud ntawm lub xibtes, xws li kab thiab quav; Thaum tau txais cov duab thib ob ntawm polarized cov duab dua, nws tsom rau cov duab sab hauv, thiab cov pob txha sab hauv, thiab cov pob txha mos los muab cov duab uas muaj cov duab muaj. Cov duab no tau pom zoo, ua kom pom tseeb, thiab qhia cov xibtes hauv ib qho kev qhia tshwj xeeb, thiab sau npe rau sab laug lossis sab tes xis.

Tam sim no, Amazon txoj kev paub txog kev siv thev naus laus zis tuaj yeem txheeb xyuas tus kheej tus kheej thiab tsis tas yuav tsum siv lawv txhais tes rau ntawm cov khoom siv scanning, tsuas yog yoj thiab scan tsis muaj kev sib cuag. Tus nqi tsis ua haujlwm ntawm cov thev naus laus zis yog li 0.0001%. Nyob rau tib lub sijhawm, lub Palmin lees paub yog ob qho kev txheeb xyuas ob npaug - thawj zaug kom tau txais cov yam ntxwv sab nraud, thiab lub sijhawm thib ob kom tau txais cov yam ntxwv hauv kev ua haujlwm. Piv nrog rau lwm cov thev naus laus zis hauv cov kev ruaj ntseg, txhim kho.

Ntxiv nrog rau cov lus saum toj no, IRIS lees paub cov thev naus laus zis kuj tseem tau txais nrov. Qhov tseeb lees paub tus nqi ntawm IRIS lees paub yog tsawg li 1/1000000. Nws tsuas yog siv cov yam ntxwv ntawm iris lub neej invariance thiab qhov sib txawv los txheeb xyuas tus kheej.

Tam sim no, kev pom zoo hauv kev lag luam yog tias kev lees paub ntawm kev ua tiav ntawm lub ntsej muag thiab kev nyab xeeb, thiab ntau qhov kev lees paub nyob hauv kev lees paub thiab kev lees paub biometric-tsis yog los ntawm ntau txoj kev Txhawm rau txhawm rau txhim kho qhov raug lees paub txog qhov tseeb thiab tsis pub lwm tus paub txog cov thev naus laus zis rau cov thev naus laus zis rau qee yam. Piv nrog cov tsoos ib txwm-hom algorithm, nws tuaj yeem ua tau zoo dua li ntawm kaum lab), uas tseem yog qhov tseem ceeb ntawm kev txhim kho biometric cim.

MULTIMODAL BIOMETRIC SYSTEM

Cov Tshuab MultIMOtric Biometric Biometric siv ntau sensors lossis biometrics kom kov yeej cov kev txwv ntawm Iris, tuaj yeem ua rau cov ntiv tes hluav taws xob tsis zoo tuaj yeem ua rau hnav los yog txiav cov ntiv tes. Thaum lub sijhawm tsis muaj peev xwm cuam tshuam muaj tsawg ntawm lawv tus kheej, nws tsis zoo li ntawd ntau qhov tseem ceeb yuav raug kev txom nyem ib yam nkaus. Cov tshuab multimodal biometric tuaj yeem tau cov ntaub ntawv los ntawm tib lub cim (piv txwv li cov duab luam tawm) lossis cov ntaub ntawv ntawm cov ntiv tes sib txawv (siv cov nkauj tau lees paub, cov lus pom zoo nkauj tshaj tawm).

Cov Tshuab Multlimodal Biometric tuaj yeem fuse cov tshuab tsis txaus ntseeg, ib txhij, uas yog sib xyaw ua ke, sib txuas, sib xyaw ua ke thiab kev sib koom ua ke.

Kiab cuatau tsim muaj cov lus ntawmBiometric lo ntsiab muagTxog kev paub txog ntsej muag, Palmrmin tau lees paub zoo li cov nkauj sau npe thiab IRIS IDEYNTION LEN3659A yog tsim rau 1 / 1.8 '' sensors. Nws muaj txhua yam iav thiab kev cog lus tsim nrog mere 11.95 hli TTL. Nws ntes 44 degrees kab rov tav teb ntawm pom. Cov lens no zoo tagnrho rau kev pom tau pom kev.
