1. Lub tswv yim ntawm cov ntaub ntawv masking
Cov ntaub ntawv masking tseem hu ua cov ntaub ntawv masking. Nws yog txoj kev qhia txuj ci hloov, hloov kho lossis npog cov ntaub ntawv rhiab lossis lwm cov ntaub ntawv hauv npav thiab lwm cov ntaub ntawv thaum peb tau muab daim npog cov cai thiab cov cai. Cov txheej txheem no feem ntau yog siv los tiv thaiv cov ntaub ntawv rhiab los ntawm kev siv ncaj qha hauv cov neeg tsis muaj peev xwm.
Cov ntaub ntawv masking daim iav yuav tsum ceev cov ntaub ntawv cov ntaub ntawv qub, cov cai ua lag luam kom ntseeg tau tias qhov kev tsim kho ua lag luam, thiab tshuaj ntsuam yuav tsis cuam tshuam los ntawm daim npog ntsej muag. Xyuas kom meej cov ntaub ntawv sib xws thiab siv tau ua ntej thiab tom qab masking.
2. Cov ntaub ntawv npog cov ntaub ntawv
Cov ntaub ntawv masking tuaj yeem faib ua cov ntaub ntawv pov thawj cov ntaub ntawv zoo li qub (SDM) thiab Dynamic Discining (DDM).
Cov ntaub ntawv teev cov ntaub ntawv zoo li qub (SDM): Daim npog cov ntaub ntawv mas zoo li qub yuav tsum tau tsim los ntawm cov chaw tsim khoom tshiab uas tsis tseem tshiab rau kev rho tawm ntawm cov chaw tsim khoom. Cov ntaub ntawv rhiab yog muab rho tawm los ntawm cov ntaub ntawv ntau lawm thiab tom qab ntawd khaws cia hauv cov ntaub ntawv tsis yog ntau lawm. Nyob rau hauv txoj kev no, cov ntaub ntawv dimensities yog cais los ntawm cov kev lag luam ntau lawm, uas ua tau kev ruaj ntseg ntawm cov ntaub ntawv ntau lawm.
Dynamic Cov Ntaub Ntawv Daim Npog (DDM): Nws yog feem ntau siv nyob rau hauv cov chaw ua haujlwm ntau lawm kom cov ntaub ntawv rhiab hauv cov ntaub ntawv tiag tiag. Qee zaum, qib ua kom sib txawv ntawm daim npog ntsej muag yuav tsum tau nyeem tib cov ntaub ntawv rhiab hauv cov xwm txheej sib txawv. Piv txwv li, txoj haujlwm sib txawv thiab kev tso cai yuav siv cov qauv sib txawv.
Cov ntaub ntawv tshaj tawm thiab cov ntaub ntawv cov khoom siv npog ntsej muag
Xws li cov xwm txheej zoo li suav nrog cov khoom lag luam sab hauv lossis cov ntaub ntawv pabcuam sab nraud, xws li cov ntaub ntawv kev lag luam thiab tshuaj xyuas kev lag luam.
3. Cov ntaub ntawv mas cov tshuaj tov
Cov ntaub ntawv pov thawj cov ntaub ntawv ua haujlwm suav nrog: Qhov tsis raug, cov nqi hloov, cov ntaub ntawv hloov, tus nqi nruab nrab, offset thiab rounding, thiab lwm yam.
Tsis raug: Tsis raug yog hais txog kev encryption, truncation, lossis zais cov ntaub ntawv rhiab. Cov txheej txheem no feem ntau hloov cov ntaub ntawv tiag tiag nrog cov cim tshwj xeeb (xws li *). Kev ua haujlwm yog yooj yim, tab sis cov neeg siv tsis tuaj yeem paub cov qauv ntawm cov ntaub ntawv qub, uas tuaj yeem cuam tshuam cov ntaub ntawv sau ua ntaub ntawv txuas ntxiv.
Random Nqi: Tus nqi random yog hais txog kev hloov cov ntaub ntawv rhiab (cov lej hloov cov lej, cov tsiaj ntawv hloov cov tsiaj ntawv, thiab cov cim hloov cov cim). Daim npog ntsej muag no yuav ua kom cov ntaub ntawv rhiab rau qee yam thiab muab cov ntaub ntawv txuas ntxiv. Yuav tsum muaj daim ntawv txhais cov lus txhais rau cov lus zoo nkauj rau qee cov lus uas muaj ntsiab lus, xws li cov neeg thiab cov chaw.
Cov ntaub ntawv hloov: Cov ntaub ntawv hloov tau zoo ib yam li daim npog ntsej muag ntawm Null thiab Random qhov tseem ceeb, tsuas yog qhov tseem ceeb, cov ntaub ntawv npog ntsej muag yog hloov nrog tus nqi tshwj xeeb.
Symmetric encryption: Symmetric encryption yog ib hom kev npog ntsej muag tshwj xeeb. Nws zais cov ntaub ntawv rhiab los ntawm cov yuam sij encryption thiab algorithms. Hom CIPHertext hom yog ib yam nrog cov ntaub ntawv qub hauv cov cai muaj kuab.
Xws luag: Lub phiaj xwm nruab nrab feem ntau siv hauv cov xwm txheej teev ntuj. Txog cov ntaub ntawv sau txog cov lej, peb xub laij lawv cov txhais tau tias, thiab tom qab ntawd faib cov txiaj ntsig desensitized nyob ib ncig ntawm lub ntsiab lus, yog li ua kom cov lej ntawm cov ntaub ntawv tas li.
Offset thiab rounding: Cov qauv no hloov cov ntaub ntawv digital los ntawm kev hloov pauv. Qhov kev sib tw offset ua kom muaj kev tiv thaiv kev kwv yees thaum muaj kev ruaj ntseg ntawm cov ntaub ntawv tiag tiag li yav dhau los cov qauv ntawm cov xwm txheej ntawm cov ntaub ntawv tshawb fawb loj.
Tus qauv pom zoo "Ml-npb-5660"Rau cov ntaub ntawv masking
4. Cov qauv siv cov ntaub ntawv pov tseg
(1). Cov Qauv Txheej Txheem
Cov ntaub ntawv ntsuas thiab cov ntaub ntawv sau tseg
- Cov ntaub ntawv ntsuas: Kev soj ntsuam thiab ntsuas ntawm cov ntaub ntawv qub los ntawm kev xaiv cov ntaub ntawv pov thawj ntawm cov tswv yim ntawm kev ua haujlwm ntawm cov tswv yim.
- Cov ntaub ntawv kev sib sau ua ke: Ua kev sau cov txheej txheem txheeb cais (xws li suav cov ntsiab lus (feem ntau, siab tshaj plaws) thov kom muaj tus sawv cev ntawm txhua cov ntaub ntawv hauv cov ntaub ntawv qub teev.
(2). Cryptography
Cryptography yog ib txoj kev nquag ua rau desensitize lossis txhim kho qhov ua tau zoo ntawm kev ua kom zoo. Ntau hom kev sib txawv ntawm encryption algorithms tuaj yeem ua tiav cov teebmeem sib txawv.
- Kev txiav txim siab kev txiav txim siab: Qhov tsis yog-random sympermetric modryption. Nws feem ntau yog cov ntaub ntawv ID ua haujlwm thiab tuaj yeem kho cov ntaub ntawv thiab rov qab ua kom tiav CIPHertext rau thawj daim ID thaum tsim nyog, tab sis tus yuam sij yuav tsum tau muaj kev tiv thaiv kom raug.
- Irreversible encryption: Tus muaj nuj nqi hash yog siv los ua cov ntaub ntawv, uas feem ntau yog siv rau cov ntaub ntawv ID. Nws tsis tuaj yeem yog kho kom zoo nkauj ncaj qha thiab kev sib raug zoo yuav tsum tau txais kev cawmdim. Tsis tas li ntawd, vim yog qhov tshwj xeeb ntawm hash ua haujlwm, kev sib tsoo cov ntaub ntawv yuav tshwm sim.
- Homomorphic encryption: Lub Ciphertin HomomphIC homomphIC yog siv. Nws cov yam ntxwv yog tias kev ua haujlwm ciphertext ua haujlwm yog tib yam li kev ua haujlwm ntawm kev ua haujlwm tom qab txiav txim siab. Yog li ntawd, nws feem ntau siv los ua cov lej suav sau, tab sis nws tsis dav siv rau cov kev ua tau zoo.
(3). Tshuab
Lub Technression thev naus laus zis lossis cov ntaub ntawv thaiv cov ntaub ntawv uas tsis muaj kev tiv thaiv kev tiv thaiv ntiag tug, tab sis tsis tshaj tawm.
- Masking: nws hais txog txoj kev xav tau zoo tshaj plaws los npog tus lej cim, xws li tus lej sib ntaus, daim npav ID yog cim nrog lub hnub qub, lossis qhov chaw nyob yog txiav tsis tau.
- Lub zos supression: Hais txog tus txheej txheem ntawm kev tshem tawm cov cwj pwm tshwj xeeb (kab ntawv), tshem tawm cov ntaub ntawv tsis tseem ceeb;
- Cov ntaub ntawv supression: Hais txog tus txheej txheem ntawm kev rho tawm cov ntaub ntawv tshwj xeeb (kab), tshem cov ntaub ntawv tsis tseem ceeb.
(4). Pseudonym technology
Pseudomanning yog tus txheej txheem ntawm tus kheej uas siv cov lus qhia pseudononym los hloov cov cim ncaj qha (lossis lwm tus neeg pom kev rhiab). Cov tswv yim tseem ceeb tsim cov cim tshwj xeeb rau txhua tus neeg cov ntaub ntawv, tsis yog cim ncaj qha lossis nkag siab.
- Nws tuaj yeem tsim kom muaj nuj nqis randomes ntawm tus kheej sib haum rau tus thawj ID, txuag lub rooj zaum saib xyuas cov rooj zaum.
- Koj tseem tuaj yeem siv encryption los tsim cov pseudonyms, tab sis yuav tsum khaws cov yuam sij decryption kom raug;
Cov thev naus laus zis no tau siv dav dav ntawm cov neeg siv cov ntaub ntawv ywj pheej, xws li Openid hauv qhib platform science, uas cov neeg tsim tawm sib txawv tau txais cov khoom siv sib txawv rau cov neeg siv sib txawv.
(5). Cov txheej txheem dav dav
Cov txheej txheem dav dav yog hais txog cov txheej txheem ntawm tus kheej uas txo cov cim uas tau xaiv hauv cov ntaub ntawv thiab muab cov lus piav qhia ntau dua ntawm cov ntaub ntawv. Cov cuab yeej siv thev naus laus zis yog qhov yooj yim los siv thiab tuaj yeem tiv thaiv cov qhabnias ntawm cov ntaub ntawv theem. Nws yog feem ntau siv nyob rau hauv cov ntaub ntawv cov khoom lag luam lossis cov ntaub ntawv xov xwm.
- Kev Sib Tw: Koom nrog xaiv cov kev sib tshooj rau tus cwj pwm xaiv, xws li upward lossis downward forensics, yielding cov txiaj ntsig 100, 500, 1k, thiab 10k
- Cov tswv yim saum thiab hauv qab los: Hloov cov nuj nqis saum toj no (lossis hauv qab) qhov pib ntawm cov "saum toj X" lossis "hauv qab x"
(6). Randomizents Cov Txheej Txheem
Ua ib hom kev qhia txog tus kheej, Randomization hais txog tus nqi ntawm kev xaiv los ntawm romementization, kom cov nqi tom qab sib txawv ntawm tus nqi qub tiag tiag. Cov txheej txheem no txo lub peev xwm ntawm tus neeg tawm tsam los ua tus cwj pwm tus nqi ntawm tib cov ntaub ntawv cov ntaub ntawv, tab sis cuam tshuam rau cov ntaub ntawv muaj tseeb ntawm cov ntaub ntawv xeem, uas muaj nrog cov ntaub ntawv xeem ntau.
