Yuav Ua Li Cas NFC Tau Txais Kev Tiv Thaiv Kev Ua Phem?

NFC anti-counterfeiting nti siv cov thev naus laus zis hauv kev sib txuas lus ze rau hauv cov ntaub ntawv cov khoom lag luam rau hauv cov nti me me, thiab sib koom ua ke cov ntawv pov thawj pov thawj nrog cov khoom lag luam los ntawm kev siv txuj ci xws li cog, pasting, thiab synthesis. Thaum nws nyob ze rau kev nyeem ntawv / nkag ntaus ntawv, Hloov kho cov kev ncig / kev txheeb xyuas cov ntaub ntawv ntawm cov khoom, tab sis tus nqi ntawm imitation ntawm cov nti yog siab thiab cov ntaub ntawv tiag tiag ntawm cov khoom yog qhov nyuaj rau luam, uas dhau los ua qhov zoo tshaj plaws feature uas. NFC nti tuaj yeem dhau los ua daim ntawv lo tiv thaiv cuav.

Lub tswv yim tseem ceeb ntawm kev tiv thaiv cov khoom lag luam yog muab cov khoom lag luam no cim logo, thiab nws tsuas yog cuam tshuam nrog lub platform tshwj xeeb. Yog tias qhov cim tshwj xeeb no tsis tuaj yeem pom ntawm lub platform cuam tshuam, ces cov khoom raug txheeb xyuas tias yog cuav.

· Ib tus cim tshwj xeeb

· Tsuas yog koom nrog cov platforms tshwj xeeb

· Kev txheeb xyuas thiab cov ntaub ntawv sib piv platform

Cov txiaj ntsig tsis sib xws: pom tias yog cuav

RFID thiab NFC muaj zog tiv thaiv kev ua txhaum cai. Txhua nti muaj qhov tshwj xeeb UID hauv ntiaj teb. Cov neeg nyiag khoom tsis tuaj yeem tau txais cov nti sib haum rau UID. Cov txheej txheem technical yog siab heev. Nws tseem tuaj yeem sau thiab khaws cov ntaub ntawv ntawm txhua qhov txuas ntawm cov khoom lag luam txhawm rau taug qab qhov chaw ntawm cov khoom. Yog li nws tsis tuaj yeem raug faked. Tshwj xeeb tshaj yog NFC thev naus laus zis tshem tawm qhov muaj peev xwm ntawm kev ua txhaum cai. Txawm hais tias cov neeg cuav siv nyiaj ntau heev kom tau txais cov cuab yeej, lawv tsis tuaj yeem dag nws nrog kev tsim cov chips thiab rov sau cov thev naus laus zis.

Yuav ua li cas NFC tsis raug cuav?

1. Cov ntawv tsis yooj yim

Lub hom phiaj ntawm cov neeg dag ntxias kev coj tus cwj pwm ntawm cov ntawv sau rov qab thiab sau cov cawv txiv hmab cuav nrog lub fwj tiag, cov ntawv tsis muaj zog yog tsim, ua ke nrog cov qauv tsim ntawm daim ntawv lo, tsuav yog qhib cov cawv, daim ntawv lo yuav tawg thiab siv tsis tau ntxiv! Yog tias daim ntawv lo raug tshem tawm, daim ntawv lo yuav tsum tau tawg, txawm tias nws raug tshem tawm, nws siv tsis tau.

2. Anti-cloning

Lub hom phiaj ntawm kev ua ntawm cloning cim npe los ntawm cov neeg cuav, NFC nti hauv daim ntawv yog tsim nrog kev ruaj ntseg encryption algorithm, thiab ib qho asymmetric encryption algorithm yog siv kom tau txais cov ntawv ciphertext. Xws li ciphertext yog irreversible. Txawm hais tias tus neeg cuav tau txais daim npav ID, tseem tsis muaj txoj hauv kev kom tau txais cov ntawv ciphertext. Tus nqi siab ntawm NFC chips yuav cuam tshuam ntau tus neeg dag, ua ke nrog kev ruaj ntseg encryption algorithms thiab irreversible ciphertext, kiag li kaw tawm lub tswv yim ntawm cov neeg cuav cloning thiab xyaum.

3. Kev ruaj ntseg

Lub 7-byte tshwj xeeb UID raug hlawv tawm ntawm lub Hoobkas kom paub meej tias tus lej ID yog qhov tshwj xeeb; tom qab cov ntaub ntawv tau sau, nws raug hlawv, thiab tsis muaj leej twg (xws li tus tsim tawm nws tus kheej) tuaj yeem hloov tau thiab tsuas yog nyeem tau; 32-me ntsis kev tiv thaiv tus yuam sij zais cia, Tsis muaj kev tso cai, tsis tuaj yeem ua haujlwm sau ntawv, ntoo dab ua phem tawm tsam invalidation lub sij hawm teeb tsa muaj nuj nqi.

4. Lwm yam txuj ci

Tsis xav tau APP. Cov neeg siv khoom siv NFC rau kev tiv thaiv kev ua pov thawj tsis tau rub tawm APP, uas yog ib qho ntawm qhov sib txawv ntawm RFID los tiv thaiv kev ua txhaum cai. Tsis xav tau APP los ua kom NFC tiv thaiv kev ua txhaum cai muaj kev paub zoo dua ntawm cov neeg siv khoom, tuav qhov sib koom ua ke, NFC + blockchain, tus khub muaj zog tshaj plaws hauv kev tiv thaiv kev ua txhaum cai!
