Hloov tshiab: Apple tau hais txog kev tshuaj xyuas thib ob ntawm tus neeg rau zaub mov, thiab lub tuam txhab kev tshaj lij hauv computer pom tau hais txog qhov muaj peev xwm ntawm qhov no tuaj yeem piav qhia hauv "Yuav ua li cas kev soj ntsuam zaum ob yuav ua haujlwm" hauv qab no.
Tom qab cov neeg tsim khoom thim rov qab tsim cov khoom ntawm nws, qhov ntxov version ntawm Apple CSAM system tau raug ntxias kom ua tiav cov duab dawb huv.Txawm li cas los xij, Apple tau hais tias nws muaj kev tiv thaiv ntxiv los tiv thaiv qhov no los ntawm kev tshwm sim hauv lub neej tiag tiag.
Qhov kev txhim kho tshiab tshaj plaws tau tshwm sim tom qab NeuralHash algorithm tau tshaj tawm rau qhib qhov chaw tsim tawm lub vev xaib GitHub, leej twg tuaj yeem sim nrog nws…
Txhua lub CSAM ua haujlwm los ntawm kev xa cov ntaub ntawv ntawm cov ntaub ntawv kev tsim txom menyuam yaus uas paub txog kev sib deev los ntawm cov koom haum xws li National Center for Missing and Exploited Children (NCMEC).Lub database yog muab nyob rau hauv daim ntawv ntawm hashes los yog digital ntiv tes los ntawm cov duab.
Txawm hais tias feem ntau cov thev naus laus zis thev naus laus zis luam theej duab duab tso rau hauv huab, Apple siv NeuralHash algorithm ntawm tus neeg siv khoom lub iPhone los tsim tus nqi hash ntawm cov duab khaws cia, thiab tom qab ntawd muab piv nrog cov ntawv rub tawm ntawm CSAM hash tus nqi.
Nag hmo, tus tsim tawm tau thov kom rov qab kho Apple lub algorithm thiab tso tawm cov cai rau GitHub-qhov kev thov no tau lees paub zoo los ntawm Apple.
Tsis pub dhau ob peb teev tom qab GitHib raug tso tawm, cov kws tshawb fawb tau ua tiav siv cov txheej txheem los tsim qhov kev xav tsis tseeb zoo-ob qhov sib txawv kiag li cov duab uas ua rau tib tus nqi hash.Qhov no yog hu ua kev sib tsoo.
Rau cov tshuab zoo li no, yeej ib txwm muaj kev pheej hmoo ntawm kev sib tsoo, vim hais tias tus hash yog qhov yooj yim heev uas sawv cev ntawm cov duab, tab sis nws yog qhov xav tsis thoob tias ib tus neeg tuaj yeem tsim cov duab sai sai.
Kev txhob txwm sib tsoo ntawm no tsuas yog ib qho pov thawj ntawm lub tswv yim.Cov neeg tsim tawm tsis muaj kev nkag mus rau CSAM hash database, uas yuav xav tau kev tsim cov txiaj ntsig tsis tseeb hauv lub sijhawm tiag tiag, tab sis nws ua pov thawj tias kev sib tsoo yog qhov yooj yim hauv txoj cai.
Apple tau lees paub zoo tias cov algorithm yog lub hauv paus ntawm nws tus kheej lub cev, tab sis hais rau lub motherboard tias qhov no tsis yog qhov kawg version.Lub tuam txhab kuj tau hais tias nws yeej tsis xav khaws nws zais cia.
Apple hais rau Motherboard hauv email tias cov ntawv txheeb xyuas los ntawm tus neeg siv ntawm GitHub yog cov qauv siv dav, tsis yog qhov kawg version siv rau iCloud Photo CSAM nrhiav pom.Apple tau hais tias nws kuj tau tshaj tawm cov algorithm.
"Lub NeuralHash algorithm [...] yog ib feem ntawm kev kos npe rau kev khiav hauj lwm qhov chaws [thiab] cov kws tshawb fawb kev ruaj ntseg tuaj yeem tshawb xyuas tias nws tus cwj pwm ua raws li cov lus piav qhia," sau ib daim ntawv Apple.
Lub tuam txhab tau hais ntxiv tias muaj ob kauj ruam ntxiv: khiav qhov kev sib tw thib ob (tsis pub lwm tus paub) ntawm nws tus kheej server, thiab phau ntawv tshuaj xyuas.
Apple kuj tau hais tias tom qab cov neeg siv dhau qhov kev sib tw 30, qhov thib ob uas tsis yog pej xeem algorithm khiav ntawm Apple cov servers yuav kuaj xyuas cov txiaj ntsig.
"Qhov kev ywj pheej hash no tau raug xaiv los tsis lees paub qhov muaj peev xwm ua yuam kev NeuralHash cuam tshuam cov ntaub ntawv CSAM encrypted ntawm lub cuab yeej vim muaj kev cuam tshuam tsis zoo ntawm cov duab uas tsis yog CSAM thiab tshaj qhov sib piv."
Brad Dwyer ntawm Roboflow pom ib txoj hauv kev yooj yim kom paub qhov txawv ntawm ob daim duab tshaj tawm ua pov thawj ntawm lub tswv yim rau kev sib tsoo.
Kuv xav paub seb cov duab no zoo li cas hauv CLIP ntawm qhov zoo sib xws tab sis txawv neural feature extractor OpenAI.CLIP ua haujlwm zoo ib yam li NeuralHash;nws yuav siv cov duab thiab siv cov neural network los tsim cov txheej txheem vectors uas qhia txog cov ntsiab lus ntawm daim duab.
Tab sis OpenAI lub network txawv.Nws yog tus qauv dav dav uas tuaj yeem ua daim ntawv qhia ntawm cov duab thiab cov ntawv.Qhov no txhais tau tias peb tuaj yeem siv nws los rho tawm cov ntaub ntawv ntawm tib neeg nkag siab.
Kuv tau khiav ob daim duab sib tsoo saum toj no los ntawm CLIP kom pom tias nws tseem dag.Cov lus teb luv luv yog: tsis yog.Qhov no txhais tau hais tias Apple yuav tsum muaj peev xwm siv qhov thib ob feature extractor network (xws li CLIP) rau cov duab CSAM kuaj pom seb lawv puas yog tiag lossis cuav.Nws yog qhov nyuaj dua los tsim cov duab uas ntxias ob lub network tib lub sijhawm.
Thaum kawg, raws li tau hais ua ntej, cov duab raug tshuaj xyuas manually kom paub meej tias lawv yog CSAM.
Ib tus kws tshawb fawb txog kev nyab xeeb tau hais tias tsuas yog qhov txaus ntshai tiag tiag yog tias leej twg xav ua rau Apple tuaj yeem muab qhov tsis zoo rau tib neeg tshuaj xyuas.
"Apple tiag tiag tsim cov kab ke no, yog li lub hash muaj nuj nqi tsis tas yuav khaws cia zais cia, vim tias tsuas yog qhov koj tuaj yeem ua nrog 'non-CSAM li CSAM' yog ua rau Apple cov lus teb pab pawg nrog qee cov duab tsis txaus ntseeg txog thaum lawv siv cov ntxaij lim dej kom tshem tawm. tsom xam Cov khib nyiab hauv cov raj xa dej yog qhov tsis zoo, "Nicholas Weaver, tus kws tshawb fawb laus ntawm lub koom haum International Computer Science ntawm University of California, Berkeley, hais rau Motherboard hauv kev sib tham hauv online.
Kev ceev ntiag tug yog ib qho teeb meem ntawm kev txhawj xeeb ntxiv hauv ntiaj teb niaj hnub no.Ua raws li tag nrho cov lus ceeb toom ntsig txog kev ceev ntiag tug, kev ruaj ntseg, thiab lwm yam hauv peb cov lus qhia.
Ben Lovejoy yog tus kws sau ntawv Askiv thiab EU editor rau 9to5Mac.Nws paub txog nws cov kab ntawv thiab cov ntawv teev cia, tshawb nrhiav nws qhov kev paub nrog Apple cov khoom lag luam dhau sijhawm kom tau txais kev tshuaj xyuas ntau dua.Nws kuj tau sau cov dab neeg tshiab, muaj ob qho kev ua yeeb yam, ob peb zaj yeeb yaj kiab luv luv thiab rom-com!
