I-Google ivule isistimu yokuhlaziya amasethi edatha ngaphandle kokwephula ubumfihlo

Google kwethulwe Iphrothokholi ye-cryptographic yokubala okuyimfihlo kwamaqembu amaningi Joyina Okuyimfihlo futhi Ubale, okuvumela ukuhlaziya nokubalwa kumasethi edatha ebethelwe evela kubahlanganyeli abambalwa, ukugcina ubumfihlo bedatha yombambi qhaza ngamunye (umhlanganyeli ngamunye akakwazi ukuthola ulwazi mayelana nedatha yabanye ababambiqhaza, kodwa angakwazi ukwenza izibalo ezijwayelekile kubo ngaphandle kokukhishwa kwekhodi). Ikhodi yokusebenzisa iphrothokholi vula ilayisensi ngaphansi kwe-Apache 2.0.

I-Private Joyina kanye ne-Compute ikuvumela ukuthi udlulisele isethi yangasese yamarekhodi kumuntu wesithathu, ozokwazi ukuyihlaziya futhi ngokuvamile ahlole umehluko ngesethi yawo, kodwa ngeke akwazi ukuthola amanani amarekhodi athile. Isibonelo, kungenzeka ukuthola ulwazi kusethi yedatha ebethelwe, njengenombolo yezihlonzi ezifana nesethi yayo kanye nesamba samanani amarekhodi anezihlonzi ezifanayo. Kulokhu, akunakwenzeka ukuthola ukuthi yimaphi amanani nezihlonzi ezikhona kusethi.

I-Private Joyina kanye ne-Compute protocol, ebizwa nangokuthi i-Private Intersection-Sum, kusekelwe ekuhlanganisweni kwephrothokholi ukudluliswa okukhohlwa ngengozi (Ukudluliswa Okungahleliwe), kubethelwe Izihlungi zeBloom kanye nokuzifihla kabili UPolig-Hellman.

Uhlelo oluhlongozwayo lungase lube usizo, isibonelo, lapho isikhungo sezokwelapha esisodwa sinolwazi mayelana nesimo sezempilo seziguli, kanti esinye mayelana nokunikezwa komuthi omusha wokuvimbela. Iphrothokholi "Yokujoyina kanye Nokuhlanganisa Kwangasese" ikuvumela, ngaphandle kokudalula ulwazi, ukuhlanganisa amasethi edatha abethelwe futhi ubonise izibalo ezijwayelekile ezizokuvumela ukuthi uqonde ukuthi umuthi onqunyiwe uyanciphisa ukwenzeka kwezifo noma cha. Esinye isibonelo ukuthi ngokusekelwe ku-database yezingozi ezivela ku-state traffic inspectorate kanye nesisekelo sokusetshenziswa kwemishini yokuphepha ethuthukisiwe ezimotweni, kungenzeka ukuhlola ukuthi ukubukeka kwalezi zinsimbi kuthinta inani lezingozi.

Esinye isibonelo yilapho, ngokusekelwe esisekelweni sesisebenzi senkampani eyodwa kanye nedatha yokuthenga kwenye, ungakwazi ukubala ukuthi bangaki abasebenzi abavela enkampanini yokuqala abathenge kweyesibili nokuthi ngaliphi inani. Kumongo wamanethiwekhi okukhangisa, izibalo ezifanayo zingenziwa ukuze kuhlolwe ukusebenza kahle kwemikhankaso yokukhangisa, kusetshenziswa uhlu lwabasebenzisi ababoniswe isikhangiso (noma abachofoze isixhumanisi) nabathenge esitolo se-inthanethi.
