Google yatsegula njira yowunikira ma data popanda kuphwanya chinsinsi

Google представила cryptographic protocol yowerengera zachinsinsi zamagulu ambiri Lowani nawo payekha komanso Pangani, zomwe zimalola kusanthula ndi kuwerengera pamagulu osungidwa achinsinsi kuchokera kwa otenga nawo mbali angapo, kusunga chinsinsi cha deta ya wophunzira aliyense (aliyense sangathe kupeza zambiri zokhudza zomwe akutenga nawo mbali, koma akhoza kupanga mawerengedwe amtundu uliwonse popanda kumasulira). Code yokhazikitsa protocol ndi lotseguka zololedwa pansi pa Apache 2.0.

Private Join and Compute imakupatsani mwayi wosinthira zolemba zachinsinsi kwa munthu wina, yemwe azitha kuzisanthula ndikuwunikanso kusiyana kwake ndi seti yawo, koma sangathe kudziwa mayendedwe ake. Mwachitsanzo, ndizotheka kupeza zidziwitso kuchokera ku seti yobisidwa, monga kuchuluka kwa zozindikiritsa zomwe zimagwirizana ndi seti yake komanso kuchuluka kwa ma rekodi okhala ndi zozindikiritsa zofanana. Pankhaniyi, ndizosatheka kudziwa ndendende zomwe zikhalidwe ndi zizindikiritso zomwe zilipo mu seti.

Private Join and Compute protocol, yomwe imatchedwanso Private Intersection-Sum, maziko pa protocol kuphatikiza kufala mwangozi moyiwala (Mwachisawawa Chosamutsidwa), chosungidwa zosefera pachimake ndi kubisa kawiri Polig-Hellman.

Dongosolo lomwe likufunsidwa lingakhale lothandiza, mwachitsanzo, ngati bungwe lina lachipatala lili ndi chidziwitso chokhudza thanzi la odwala, ndipo linanso la kulembedwa kwamankhwala atsopano odzitetezera. Protocol ya "Private Join and Compute" imakupatsani mwayi, popanda kuwulula zambiri, kuphatikiza ma data obisika ndikuwonetsa ziwerengero zomwe zingakuthandizeni kumvetsetsa ngati mankhwalawa amachepetsa kuchuluka kwa matenda kapena ayi. Chitsanzo china ndi chakuti kutengera nkhokwe za ngozi zochokera ku boma loyang'anira magalimoto komanso maziko a kugwiritsa ntchito zida zotetezera bwino m'magalimoto, ndizotheka kuwunika ngati mawonekedwe a zidazi amakhudza kuchuluka kwa ngozi.

Chitsanzo china ndi pamene, kutengera maziko a antchito a kampani imodzi ndikugula deta kuchokera kwa wina, mutha kuwerengera angati ogwira ntchito kukampani yoyamba adagula kuchokera kwachiwiri komanso kuchuluka kwake. Pankhani ya maukonde otsatsa, kuwerengera kofananako kungapangidwe kuti awone momwe kampeni yotsatsa imathandizira, pogwiritsa ntchito mindandanda ya ogwiritsa ntchito omwe adawonetsedwa zotsatsa (kapena omwe adadina ulalo) komanso omwe adagula pasitolo yapaintaneti.
