1. Umqondo wokuhlanganiswa kwedatha
I-Masking yedatha yaziwa nangokuthi imasking yedatha. Kuyindlela yezobuchwepheshe yokuguqula, ukuguqula noma ukumboza idatha ebucayi efana nenombolo yocingo ephathekayo, inombolo yekhadi lasebhange kanye nolunye ulwazi lapho sinikeze imithetho nezinqubomgomo. Le ndlela isetshenziselwa ukuvikela idatha ebucayi ukuthi isetshenziswe ngqo ezindaweni ezingathembeki.
Isimiso se-Mask Sing: Ukuhlanganiswa kwedatha kufanele kugcinwe izici zedatha yasekuqaleni, imithetho yebhizinisi, kanye nokuhambisana kwedatha ukuqinisekisa ukuthi ukuthuthukiswa okulandelayo, ukuhlolwa, kanye nokuhlaziywa kwedatha ngeke kuthintwe maskang. Qinisekisa ukuguquguquka kwedatha kanye nokusebenza ngaphambi nangemva kokuhlikihla.
2. Ukuhlukaniswa kwe-Masking yedatha
I-Masking yedatha ingahlukaniswa ibe yi-Masking yedatha ye-Static Masking (SDM) kanye ne-Dynamic Masking (DDM).
I-Static Data Masking (SDM): I-Static Data Masking idinga ukusungulwa kwesizinda esisha semvelo esingewona ukukhiqizwa se-sololate kusuka kwimvelo yokukhiqiza. Idatha ebucayi ikhishwe kusuka ku-database yokukhiqiza bese igcinwa kwi-database elingakhiqizi. Ngale ndlela, imininingwane esehlisiwe ihlukaniswe nemvelo yokukhiqiza, ehlangabezana nezidingo zebhizinisi futhi iqinisekise ukuphepha kwemininingwane yokukhiqiza.
I-Dynamic Data Masking (DDM): Ngokuvamile kusetshenziswa endaweni yokukhiqiza ukuze kuncishiswe idatha ebucayi ngesikhathi sangempela. Kwesinye isikhathi, amazinga ahlukene wokumaski adingekayo ukuze afunde imininingwane efanayo ebucayi ezimweni ezihlukile. Isibonelo, izindima ezihlukile nezemvume zingasebenzisa amacebo ahlukile wokuhlikihla.
Ukubikwa kwedatha kanye nemikhiqizo yedatha yokuhlikihla
Izimo ezinjalo zibandakanya ikakhulukazi imikhiqizo yokuqapha idatha yangaphakathi noma i-Billboard, imikhiqizo yedatha yesevisi yangaphandle, nemibiko esekelwe ekuhlaziyweni kwedatha, njengemibiko yebhizinisi nokubuyekezwa kwephrojekthi.
3. Ikhambi le-Masking yedatha
Izinhlelo ezejwayelekile ze-Masking zifaka phakathi: Ukungasebenzi, inani elingahleliwe, ukushintshwa kwedatha, ukubethela kwe-Symmetric, i-offset, ukususwa kanye nokujikeleza, njll.
Ukungasebenzi kahle: Ukungasebenzi kubhekisele ekubethelweni, ukunqotshwa, noma ukucasha idatha ebucayi. Lesi sikimu sivame ukufaka esikhundleni idatha yangempela ngezimpawu ezikhethekile (ezifana nazo). Ukusebenza kulula, kepha abasebenzisi abakwazi ukuthola ifomethi yedatha yoqobo, engathinta izinhlelo zokusebenza ezilandelayo zedatha.
Inani elingahleliwe: Inani elingahleliwe libhekisela ekushintsheni okungahleliwe kwemininingwane ebucayi (izinombolo zifaka amadijithi esikhundleni samadijithi, izinhlamvu zifaka ezinye izinhlamvu, nezinhlamvu ukufaka izinhlamvu). Le ndlela yokuhlikihla izoqinisekisa ifomethi yedatha ebucayi ngezinga elithile futhi yenza lula uhlelo lokusebenza lwedatha elandelayo. Izichazamazwi zeMasking zingadingeka maqondana namazwi athile anenjongo, njengamagama abantu nezindawo.
Ukushintshwa Kwedatha: Ukubuyiselwa kwedatha kufana nokumaski kwamanani ama-null kanye namanani angahleliwe, ngaphandle kokuthi esikhundleni sokusebenzisa izinhlamvu ezikhethekile noma amanani angahleliwe, idatha yokuhlikihla ithathelwa indawo ngenani elithile.
Ukubethela kwe-symmetric: Ukubhala nge-Symmetric kuyindlela ekhethekile yokuhlaziya imaski. Ibhala ngemfihlo idatha ebucayi ngezinkinobho zokubethela nama-algorithms. Ifomethi ye-ciphertect iyahambisana nedatha yasekuqaleni emithethweni enengqondo.
-Vamile: Isikimu esijwayelekile sivame ukusetshenziswa kwizimo zezibalo. Ngemininingwane yenombolo, okokuqala sibala ukubala okushoyo, bese sisabalalisa ngezikhathi ezithile amanani ancishisiwe azungeze okushiwo, ngaleyo ndlela agcine isamba sedatha njalo.
Ukususwa nokujikeleza: Le ndlela ishintsha idatha yedijithali ngokushintshwa okungahleliwe. Ukujikeleza kwe-offset kuqinisekisa ubuqiniso obulinganiselwe bebanga ngenkathi kugcinwa ukuphepha kwemininingwane, esondelene nedatha yangempela kunezikimu ezedlule, futhi inokubaluleka okukhulu esimweni sokuhlaziywa kwedatha enkulu.
Imodeli Encomayo "ML-NPB-5660"Ngokumangalisa idatha
4
(1). Amasu Ezibalo
Isampula yeSampula kanye nokuhlanganiswa kwedatha
- ISampling yedatha: Ukuhlaziywa kanye nokuhlaziywa kwemininingwane yasekuqaleni esethwe ngokukhetha okukhona okumele kwesethi yedatha kuyindlela ebalulekile yokwenza lula ukusebenza kwamasu wokuhlonza ama-de-portification.
- Ukuhlanganiswa kwedatha: Njengeqoqo lamasu wezibalo (njengengqungquthela, ukubala, okuvinjezelwa, okuphezulu kanye nobuncane) kusetshenziswe kwimifanekiso ebekiwe yedatha yasekuqaleni.
(2). I-Phritography
I-Cryptography iyindlela ejwayelekile yokusizakala noma ukuthuthukisa ukusebenza kwe-desensitization. Izinhlobo ezahlukahlukene zama-algorithms ancryption angafinyelela imiphumela ehlukile yokuhlukumezeka.
- Ukubethela okunqumayo: Ukubethelwa kwe-symmetric okungahleliwe. Imvamisa icubungula idatha ye-ID futhi ingavuma futhi ibuyise i-cipherText kwi-ID yasekuqaleni lapho kunesidingo, kepha ukhiye udinga ukuvikeleka kahle.
- Ukubethela okungaphenduki: Umsebenzi we-Hash usetshenziselwa ukucubungula idatha, evame ukusetshenziselwa idatha ye-ID. Akunakuchazwa ngqo futhi ubudlelwane bemephu kumele basindiswe. Ngaphezu kwalokho, ngenxa yesici somsebenzi we-hashi, ukushayisana kwedatha kungenzeka.
- Ukubethelwa kwe-Homomorphic: Kusetshenziswa i-Homomorphic algorithm. Isimo saso ukuthi umphumela wokusebenza kwe-cipherText kuyafana naleyo yokusebenza kwe-plaintext ngemuva kokuhlehlisa. Ngakho-ke, kuvame ukusetshenziswa ukucubungula izinkambu zezinombolo, kepha akusetshenziswa kabanzi ngenxa yezizathu zokusebenza.
(3). Ubuchwepheshe besistimu
I-Supression Technology isusa noma ivikela izinto zedatha ezingahlangabezani nokuvikelwa kobumfihlo, kepha ayizishicileli.
- Masking: Kubhekisa kwindlela evame ukuxhaphaza indlela yokumaketha inani lemfanelo, njengenombolo yomphikisi, ikhadi le-ID limakwe nge-asterisk, noma ikheli lincishisiwe.
- Ukucindezelwa kwasendaweni: kubhekisele kwinqubo yokususa amanani athile wemfanelo (amakholomu), ukususa amasimu wedatha angabalulekile;
- Qopha ukucindezelwa: Kubhekiswa kwinqubo yokususa amarekhodi athile (imigqa), ukususa amarekhodi wedatha angabalulekile.
(4). Ubuchwepheshe be-pseudony
I-PseudoManing yindlela yokuhlonza i-de-viestication esebenzisa i-pseudonym ukufaka esikhundleni isikhombi esiqondile (noma esinye isikhombi esibucayi). Amasu we-Pseudonymty adala okokuhlonza okungafani nalelo ndaba ngayinye yolwazi, esikhundleni sokuhlonza okuqondile noma okubucayi.
- Kungakhiqiza amanani angahleliwe ngokuzimele ukuze akwazi ukuhambelana ne-ID yasekuqaleni, gcina itafula lokumepha, futhi alawule ngokuqinile ukufinyelela etafuleni lemephu.
- Ungasebenzisa futhi ukubethela ukukhiqiza ama-pseudonyms, kepha kudingeka ugcine ukhiye wokuhumusha kahle;
Lobu buchwepheshe busetshenziswa kabanzi esimweni esikhulu sabasebenzisi bedatha ezimele, njenge-OpenID esigcawini esivulekile seplatifomu, lapho abathuthukisi abahlukile bethola okuvuliwe okuvuliwe okuhlukahlukene komsebenzisi ofanayo.
(5). Amasu ajwayelekile
I-Generalization Technique ibhekisa kwinqubo yokuhlonza de-portaique enciphisa ubutha lezimpawu ezikhethiwe kwi-data yedatha futhi inikeze incazelo ejwayelekile nengaqondakali yedatha. Ubuchwepheshe be-Generalization kulula ukuyisebenzisa futhi bungavikela ubuqiniso bemininingwane yerekhodi lerekhodi. Isetshenziswa kakhulu kwimikhiqizo yedatha noma imibiko yedatha.
- Ukujikeleza: Kubandakanya ukukhetha isisekelo esiyindilinga semfanelo ekhethiwe, njenge-forensics ebheke phezulu, ethela imiphumela 100, 500, 1k
- Amasu aphezulu aphezulu naphansi
(6). Amasu Okungahleliwe
Njengohlobo lwendlela yokuhlonza de-portique, ubuchwepheshe bokungahlelwa ngokungahleliwe bubhekisele ekuguquleni inani lemfanelo ngokungahleliwe ngokungahleliwe, ukuze inani ngemuva kokungahleliwe kwehlukile kunenani langempela langempela. Le nqubo inciphisa amandla ohlaseli ukuze athole inani lemfanelo avela kwamanye amanani emfanekisweni kwirekhodi elifanayo ledatha, kepha lithinta ubuqiniso bemininingwane ephumayo, evamile ngemininingwane yokuhlola umkhiqizo.
