1. Ingqikelelo yeDatha yeMasking
Ukugcinwa kwedatha kukwabizwa ngokuba kukufihla idatha. Yindlela yobugcisa yokuguqula, ukuguqula okanye ukufihla idatha ebuthathaka njengenombolo yefowuni ephathwayo, inombolo yekhadi lebhanki kunye nolunye ulwazi xa sinikeze imithetho kunye nemigaqo-nkqubo yokufihla. Obu buchule busetyenziswa ikakhulu ukunqanda idatha ebuthathaka ekusetyenzisweni ngokuthe ngqo kwiindawo ezingathembekanga.
Umgaqo weMasking yeDatha: Ukugcinwa kwedatha kufuneka kugcine iimpawu zokuqala zedatha, imithetho yezoshishino, kunye nokufaneleka kwedatha ukuqinisekisa ukuba uphuhliso olulandelayo, uvavanyo kunye nohlalutyo lwedatha aluyi kuchaphazeleka ngokufihla. Qinisekisa ukungaguquguquki kwedatha kunye nokunyaniseka phambi nasemva kokugquma.
2. Ukuhlelwa kweDatha Making
Ukufihla idatha kunokwahlulwa ibe yi-static data masking (SDM) kunye ne-dynamic data masking (DDM).
IStatic data masking (SDM): I-Static masking masking ifuna ukusekwa kwesiseko sedatha entsha engeyiyo yokuvelisa ukuze ibekwe yodwa kwindawo yemveliso. Idatha ebukhali ikhutshwe kwi-database yemveliso kwaye igcinwe kwi-database engeyiyo yokuvelisa. Ngale ndlela, idatha ye-desensitized yodwa kwindawo yokuvelisa, ehlangabezana neemfuno zoshishino kwaye iqinisekisa ukhuseleko lwedatha yemveliso.
Ukufihla iDatha enamandla (DDM): Isetyenziswa ngokubanzi kwindawo yemveliso ukwenza ukuba buthathaka kwedatha ngexesha lokwenyani. Ngamanye amaxesha, amanqanaba ahlukeneyo okufihla ayafuneka ukuba ufunde idatha efanayo ebuthathaka kwiimeko ezahlukeneyo. Umzekelo, iindima ezahlukeneyo kunye neemvume zinokuphumeza izikimu zokufihla ezahlukeneyo.
Ingxelo yedatha kunye nemveliso yedatha yokufihla isicelo
Iimeko ezinjalo ikakhulu ziquka iimveliso zangaphakathi zokubeka iliso kwidatha okanye ibhilibhodi, iimveliso zedatha yenkonzo yangaphandle, kunye neengxelo ezisekelwe kuhlalutyo lwedatha, ezifana neengxelo zeshishini kunye nophononongo lweprojekthi.
3. Data Making Solution
Izikimu eziqhelekileyo zokufihla idatha zibandakanya: ukungasebenzi, ixabiso elingahleliwe, ukutshintshwa kwedatha, ukubethelwa kwe-symmetric, ixabiso eliphakathi, i-offset kunye nokujikeleza, njl.
Ukunganyaniseki: Ukunganyaniseki kubhekisa kuguqulelo oluntsonkothileyo, kunciphiso, okanye ukufihlwa kwedatha enovakalelo. Olu dweliso luhlala luthatha indawo yedata yokwenyani ngeesimboli ezikhethekileyo (ezinje nge *). Umsebenzi ulula, kodwa abasebenzisi abanakuyazi ifomathi yedatha yoqobo, enokuchaphazela usetyenziso lwedatha olulandelayo.
Random Ixabiso: Ixabiso elingenamkhethe libhekisa kubuyiselo olungakhethiyo lwedatha ebuthathaka (amanani abuyisela amasuntswana, oonobumba endaweni yoonobumba, kunye neempawu endaweni yamagama). Le ndlela yokufihla iya kuqinisekisa ifomathi yedatha ebuthathaka ukuya kumlinganiselo othile kwaye iququzelele usetyenziso lwedatha olulandelayo. Kusenokufuneka ukwenza izichazi-magama kumagama anentsingiselo, njengamagama abantu neendawo.
Ukutshintshwa kwedatha: Ukutshintshwa kwedatha kufana ne-masking ye-null and random values, ngaphandle kokuba endaweni yokusebenzisa abalinganiswa abakhethekileyo okanye amanani angaqhelekanga, idatha yokufihla ithathelwa indawo ngexabiso elithile.
Uguqulelo oluntsonkothileyo: Uguqulelo oluntsonkothileyo lwe-Symmetric yindlela ekhethekileyo yokufihla ukuguqulwa. Ifihla idatha ebuthathaka ngokusebenzisa izitshixo ze-encryption kunye ne-algorithms. Ifomathi ye-ciphertext iyahambelana nedatha yentsusa kwimithetho esengqiqweni.
I-avareji: Iskimu esiphakathi sisoloko sisetyenziswa kwimiba yobalo. Kwidatha yamanani, siqala ukubala intsingiselo yazo, kwaye emva koko sisasaze ngokungakhethi amaxabiso angabinawo umvano malunga nentsingiselo, ngaloo ndlela sigcina isimbuku sedatha singaguquki.
I-Offset kunye ne-Rounding: Le ndlela itshintsha idatha yedijithali ngokutshintsha okungahleliweyo. I-offset rounding iqinisekisa ubungqina obusondeleyo boluhlu ngelixa igcina ukhuseleko lwedatha, olusondeleyo kwidatha yangempela kunezicwangciso zangaphambili, kwaye inokubaluleka okukhulu kwimeko yohlalutyo lwedatha enkulu.

4. IiNdlela zokuMasking zeDatha ezisetyenziswa ngokuqhelekileyo
(1). Ubuchule boBalo
Iisampulu zedatha kunye nokuhlanganiswa kwedatha
-Iisampulu zedatha: Uhlalutyo kunye novavanyo lwedatha yentsusa esetwe ngokukhetha i-subset yommeli weseti yedatha yindlela ebalulekileyo yokuphucula ukusebenza kakuhle kweendlela zokuchonga.
- Ukudityaniswa kwedatha: Njengengqokelela yeendlela zobalo (ezifana nengqungquthela, ukubala, i-avareji, ubuninzi kunye nobuncinci) obusetyenzisiweyo kwiimpawu kwi-microdata, isiphumo simela zonke iirekhodi kwiseti yedatha yokuqala.
(2). Ubhalo ngokufihlakeleyo
I-Cryptography yindlela eqhelekileyo yokuphelisa uvakalelo okanye ukomeleza ukusebenza kobuva. Iindidi ezahlukeneyo ze-algorithms yoguqulelo oluntsonkothileyo zinokufikelela kwiziphumo ezahlukeneyo zokungazinzi.
- Uguqulelo oluntsonkothileyo oluqinisekileyo: Uguqulelo olungakhethi cala lwe-symmetric encryption. Ngokuqhelekileyo iqhuba idatha ye-ID kwaye ingakwazi ukufihla kwaye ibuyisele i-ciphertext kwi-ID yokuqala xa kuyimfuneko, kodwa isitshixo sifuna ukukhuselwa ngokufanelekileyo.
- I-encryption engenakuguqulelwa: Umsebenzi we-hash usetyenziselwa ukucubungula idatha, edla ngokusetyenziselwa idatha ye-ID. Ayinakucocwa ngokuthe ngqo kwaye unxulumano lwemephu kufuneka lugcinwe. Ukongezelela, ngenxa yesici somsebenzi we-hash, ukungqubana kwedatha kunokwenzeka.
- Uguqulelo oluntsonkothileyo lwehomomorphic: Kusetyenziswa i-ciphertext homomorphic algorithm. Uphawu lwayo kukuba isiphumo sokusebenza kwe-ciphertext siyafana naso sokusebenza kokubhaliweyo okucacileyo emva kokungafihli. Ke ngoko, isetyenziswa ngokuqhelekileyo ukucubungula amabala amanani, kodwa ayisetyenziswa ngokubanzi ngenxa yezizathu zokusebenza.
(3). Iteknoloji yeNkqubo
Itekhnoloji yocinezelo iyacima okanye ikhusele izinto zedatha ezingahambelaniyo nokhuseleko lwabucala, kodwa ayizipapashi.
- Ukufihla: kubhekiselele kweyona ndlela ixhaphakileyo yokususa umvandedwa ukufihla ixabiso lophawu, njengenombolo yomchasi, ikhadi lesazisi liphawulwe ngeenkwenkwezi, okanye idilesi inqunyulwe.
- Uxinzelelo lwendawo: ibhekisa kwinkqubo yokucima amaxabiso eempawu ezithile (iikholamu), ukususa iindawo ezingabalulekanga zedatha;
- Ukunciphisa irekhodi: kubhekiselele kwinkqubo yokucima iirekhodi ezithile (imiqolo), ukucima iirekhodi zedatha ezingabalulekanga.
(4). Iteknoloji yePseudonym
I-pseudomanning bubuchule bokungachongi obusebenzisa igama elingusinga endaweni yesazisi esithe ngqo (okanye esinye isichongi esibuthathaka). Ubuchwephesha begama-lithekisthi budala izifanisi ezizodwa zesifundo solwazi lomntu ngamnye, endaweni yezazisi ezithe ngqo okanye ezibuthathaka.
- Inokuvelisa amaxabiso angaqhelekanga ngokuzimeleyo ukuba ahambelane ne-ID yokuqala, gcina itafile yemephu, kwaye ulawule ngokungqongqo ukufikelela kwitafile yokubonisa.
-Usenokusebenzisa i-encryption ukuvelisa amagama angengowawo, kodwa kufuneka ugcine isitshixo sokufihla ngokufanelekileyo;
Le teknoloji isetyenziswa ngokubanzi kwimeko yenani elikhulu labasebenzisi bedatha abazimeleyo, njenge-OpenID kwimeko yeqonga elivulekileyo, apho abaphuhlisi abahlukeneyo bafumana ii-Openids ezahlukeneyo kumsebenzisi ofanayo.
(5). UbuChwephesha bokuGqeba
Ubuchule bokwenza izinto ngokubanzi bubhekisa kubuchule bokungachongi obunciphisa ubumbumbulu beempawu ezikhethiweyo kwiseti yedatha kwaye bubonelele ngenkcazo ngokubanzi nengekho ngqiqweni yedatha. Itekhnoloji ye-generalization kulula ukuyisebenzisa kwaye inokukhusela ukunyaniseka kwedatha yezinga lerekhodi. Isetyenziswa ngokuqhelekileyo kwiimveliso zedatha okanye iingxelo zedatha.
- Ukusondeza: kubandakanya ukukhetha isiseko sokurhangqa sophawu olukhethiweyo, olufana nophando oluphezulu okanye olusezantsi, ukuvelisa iziphumo 100, 500, 1K, kunye ne-10K
- Ubuchule bokwenza ikhowudi obuphezulu nasezantsi: Buyisela amaxabiso ngasentla (okanye ngezantsi) umgubasi omele umphakamo ongaphezulu (okanye osezantsi), unika isiphumo "ngaphezu kuka-X" okanye "ngaphantsi kuka-X"
(6). Ubuchule bokwenza Randomization
Njengoluhlobo lwe-de-identification technique, iteknoloji ye-randomization ibhekisela ekuguquleni ixabiso lempawu ngokusebenzisa i-randomization, ukwenzela ukuba ixabiso emva kokwenza i-randomization lihluke kwixabiso langempela langempela. Le nkqubo inciphisa amandla omhlaseli ukuba afumane ixabiso leempawu ezivela kwamanye amaxabiso okubaluleka kwirekhodi yedatha efanayo, kodwa ichaphazela ukunyaniseka kwedatha ebangelwayo, eqhelekileyo kunye nedatha yokuvavanya imveliso.
