Google yakavhura hurongwa hwekuongorora seti yedata pasina kutyora zvakavanzika

Google yakaunzwa cryptographic protocol ye zvakavanzika multiparty computation Private Join uye Compute, iyo inobvumira kuongorora uye kuverenga pamaseti e data akavharidzirwa kubva kune vakawanda vatori vechikamu, kuchengetedza kuvanzika kwe data yega yega yevatori vechikamu (mutori wega wega haakwanisi kuwana ruzivo pamusoro pe data yevamwe vatori vechikamu, asi anogona kuita zviverengero zvakajairika pavari pasina kunyorwa). Protocol yekushandisa kodhi kuvhura ine rezinesi pasi peApache 2.0.

Yakavanzika Join uye Compute inokutendera iwe kuendesa yakavanzika seti yemarekodhi kune wechitatu bato, anozokwanisa kuiongorora uye kazhinji kuongorora misiyano neseti yavo, asi haizokwanise kuwana kukosha kweakananga marekodhi. Semuenzaniso, zvinokwanisika kuwana ruzivo kubva kune yakavharidzirwa data seti, senge nhamba yezviziviso zvinoenderana neseti yayo uye huwandu hwehuwandu hwemarekodhi ane anofananidzira madhizaini. Muchiitiko ichi, hazvibviri kuwana chaizvo izvo zvakakosha uye zviziviso zviripo mune seti.

Yakavanzika Join uye Compute protocol, inonziwo Private Intersection-Sum, based pane protocol musanganiswa netsaona kukanganwa kutapurirana (Random Oblivious Transfer), yakavharidzirwa bloom filters uye kuvanza kaviri Polig-Hellman.

Iyo yakarongwa sisitimu inogona kubatsira, semuenzaniso, kana imwe nzvimbo yekurapa ine ruzivo nezvehutano hwevarwere, uye imwe nezve kunyoreswa kwemushonga mutsva wekudzivirira. Iyo "Private Join uye Compute" protocol inobvumidza iwe, pasina kuburitsa ruzivo, kusanganisa encrypted data seti uye kuratidza huwandu hwehuwandu hunokutendera iwe kuti unzwisise kana mushonga wakatarwa unoderedza kuitika kwechirwere kana kwete. Mumwe muenzaniso ndewekuti zvichibva pane dhatabhesi yetsaona kubva kuhurumende traffic inspectorate uye hwaro hwekushandiswa kwekuvandudzwa kwemidziyo yekuchengetedza mumotokari, zvinokwanisika kuongorora kana kutaridzika kwemidziyo iyi kunokanganisa huwandu hwetsaona.

Mumwe muenzaniso ndewekuti, zvichibva pahwaro hwevashandi veimwe kambani uye kutenga data kubva kune imwe, unogona kuverenga kuti vangani vashandi kubva kukambani yekutanga vakatenga kubva kune yechipiri uye nemari ipi. Mumamiriro ezvinhu ekushambadzira network, maverengero akafanana anogona kuitwa kuongorora kushanda kwemashambadziro ekushambadzira, uchishandisa mazita evashandisi vakaratidzwa kushambadzira (kana vakadzvanya pane chinongedzo) uye vakatenga muchitoro chendaneti.
