Kuv tau nquag sib tham txog cov tswv yim nrog cov cim tob uas tau tsim. Rau cov neeg nyeem ntawv tshiab, kuv xav rov hais dua hais tias nov hauv ntau me ntsis ntxiv hauv ib phau ntawv tshwj xeeb tshwj xeeb rau nqe lus no. Vim tias yog koj ua raws li cov xov xwm txhua hnub, nws yog qhov tseem ceeb heev uas koj yuav paub txog cov ntawv no, vim koj yuav pom tias cov tswv yim muaj kev ua si rau cov neeg. Yooj yim heev.

Deepfakes yog ua los ntawm GAN (Generic Adversarial Networks)) software hom kev kawm. Qhov no yog cov txawj ntse software uas, raws li ntau hom kabmob AI hauv lub network, tsim cov cim tawm ntawm tsis muaj dab tsi. AI yog Askiv rau Artificial Intelligence; dab tsi yog qhov tseeb txawj ntse. Lwm AI network ces kuaj cov duab tsim los ntawm thawj lub network thiab tawm tsam los yog pom zoo rau lawv. Los ntawm kev ua qhov no hauv lub voj voog, cov cim ua qhov tseeb tshaj nrog txhua kauj ruam, yog li ntawd koj tuaj yeem ua cov neeg tsis tseeb kiag li uas zoo li txhua tus neeg niaj hnub ua (uas koj tuaj yeem sib ntsib ntawm txoj kev). Yog tias koj xav paub qhov no ua haujlwm li cas, thawj zaug saib cov yees duab hauv qab ntawm NVIDIA (tus kws paub zoo dua daim card tsim lub lag luam rau PCs).

Nws tsis yog tsuas pab tau kom paub tseeb tias qhov kev sib tawm tsam no yog qhov tshwm sim, tiam sis tseem yuav ua li cas lub tob tob ntawm tus yeeb yaj kiab tau siv, piv txwv, yeeb yaj kiab los yog tsim kev tshaj tawm txog kev sib raug zoo (nrog rau tag nrho cov keeb kwm xws li cov duab thiab cov yeeb yaj duab thiab kev nyiam ntawm lwm tus) deepfake social media profiles). Piv txwv li, kev sib tham txog kev sib tham tau yooj yim raug saib xyuas los ntawm "cov neeg ua hauj lwm hauv tsev" los yog cov neeg ua hauj lwm ntawm lub lag luam ua lag luam, piv txwv li, qhov twg cov cim uas koj sib tham yuav nkaum tom qab qhov tobfaiv profile (uas nws cov phooj ywg network kuj muaj cov kev sib txuas lus sib cav). Lawv tuaj yeem tua tib neeg ntawm lawv lub sijhawm hauv kev sib tham thiaj li ua siab ncaj ntawm cov neeg nyob hauv ib qho kev coj.

Cia peb saib tag nrho cov ntawv thov, tab sis ua ntej peb pib, nws yog ib qho tseem ceeb kom paub tias qhov kev ua si thiab zaj duab xis kev lag luam, tab sis kuj TV producers, tau muaj cov tswv yim xws li ntev. Txawm li cas los xij, txoj haujlwm tseem niaj hnub ua kom yooj yim rau koj xws li koj tuaj yeem ua koj tus kheej rau hauv lub tsev-vaj tsev-thiab-chav ua noj PC.

Thaum Povlauj Walker tuag hauv nruab nrab ntawm Kev Yoojyim thiab Ntxhais 7, Weta Digital lub tuam txhab raug hu los ua kom tiav zaj yeeb yaj duab version ntawm Paul Walker. Raws li kev sib txuas ntawm cov qauv xws li cov duab qub qub, kev kuaj pom ntawm Paul cov kwv tij thiab kev ntaus thawj ntawm Paul lub taub hau, Weta Digital coj Paul Walker rov qab los rau lub neej. Daim duab hauv qab no qhia txog qhov kev ua haujlwm li cas.

Lub 3D suab lus nyhav txheej txheem tau muaj nyob rau xyoo uas cov neeg koom nrog coj hnav cov ntawv sau lawv cov taw thiab mam li superimpose cov cim tsim digitally ntawm CGI. Uas yog piv rau cov txheej txheem uas siv rau Paul Walker, tsuas yog nrog cov neeg koom ua ke uas hnav lub suab seev cev. Cov txheej txheem uas muaj tam sim no kuj muaj rau cov neeg uas tsis tshuav nyiaj (saib video hauv qab no), tiam sis ib qho piv txwv zoo ntawm ib zaj yeeb yaj kiab uas siv cov txuj ci no twb tau siv yog movie Avatar from 2009 (saib no).

NVIDIA twb tau ntes tau nrog kev siv cov kev sib foob thiab CGI tshuab, vim nws siv neural networks los cob qhia software. Qhov tseeb, qhov no yog tib qho txheej txheem tom qab lub qhov tob tob. NVIDIA yog tam sim no tsis tau tsuas yog muaj peev xwm tsim cov ntsej muag tsis muaj nyob, tab sis tuaj yeem tsav los ntawm ib lub nroog nrog lub koob yees duab thiab tig mus rau hauv lub caij ntuj no (hauv lub sijhawm tiag). Xws li cov tswv yim yuav siv los cob qhia AI software ntawm kev tsav tsheb rau tus kheej hauv kev hloov huab cua, tab sis lawv tuaj yeem siv tau los ua cov lus tsa suab uas tsis tsim nyog. Ib qho yooj yim GoPro koob yees duab lossis webcam yog qhov txaus. Ua zoo saib ntawm 1: 03 min. Nyob rau hauv video hauv qab no saib seb qhov ntawd ua haujlwm li cas.

Tam sim no koj yuav xav hais tias qhov tseem yuav ua qhov no rau ntawm lub sijhawm tsis muaj tiag. Rov xav dua. Peb twb pom saum toj no tias nws yog ib qho ua tau los tsim cov neeg tsis yog-cov neeg nyob hauv Cov Chaw Haujlwm Kev Tawm Tsam Tswv Yim. Peb tam sim no paub tias ob qho tib si lub nroog ib puag ncig thiab ib tus cwj pwm yuav raug generated ntawm neural networks. Lo lus nug yog seb qhov ntawd tseem ua tau nyob rau ntawm lub sijhawm. Qhov ntawd yog qhov uas siv technology ntawm real-time lub ntsej muag reenactment los. Qhov no tau nyob ze rau lub PC yooj yim txij thaum xyoo 2015 (saib cov duab hauv qab no).

Txhua yam, peb thiaj li tau hais tias nws tau ua tau rau ntau xyoo los tsim cov yeeb yaj duab sib sib zog nqus. Txawm li cas los xij, lub tshuab tam sim no tau sim ua kom yooj yim nrog qhov tshwm sim ntawm Generative Adversarial Networks, neural networks thiab lub sij hawm real-time reenactment, tias koj tuaj yeem tsim tau tag nrho keeb kwm ntawm tus neeg tsis muaj nyob rau hauv ib qho teeb meem ntawm feeb, kev sib tham nyob ntawm tus neeg tsis yog muaj peev xwm tsim ib puag ncig los ntawm cov koob yees duab ntawm kev xav thiab txhua yam huab cua.

Dab tsi yog qhov cuam tshuam ntawm qhov no? Yuav pib nrog, koj tuaj yeem hais tias koj tsis tau tso siab rau 100% rau xyoo. Saib no ntev npaum li cas CGI cov tswv yim tau raug siv hauv kev lag luam ua yeeb yam. Txawm li cas los, thaum lub sij hawm nws yog yooj yim heev uas leej twg nrog ib daim phiaj siv nyiaj ntawm ob peb txhiab euros tau ua li no. Yog tias peb xav tias cov ntawv tshaj tawm yog kev ncaj ncees, ces peb tuaj yeem xav tias lawv tsis tau siv cov tswv yim zoo li no rau xyoo. Txawm li cas los xij, yog tias peb siv rau hauv cov nyiaj tau tias tsoom fwv siv psychological kev khiav hauj lwm rau kev puas siab puas ntsoog coj cov neeg mus rau hauv qhov txaus ntseeg hom tshiab thiab cov cai tsim, ces peb yuav tsum paub tias xyoo tau muaj kev tsis muaj ib yam dab tsi nyob rau hauv txoj kev ua fake xov xwm. Nyob rau hauv cov ntsiab lus nws yog nthuav heev kom paub tias lub teb chaws coob tshaj plaws xov xwm lub koom haum (lub Algemeen Nederlands Persbureau; muab lub npe ANP) yog nyob rau hauv ib txhais tes ntawm ib tug tsim kom muaj TV (leej twg yog tus billionaire). Peb yuav tsum loj npaum li cas kom paub meej tias cov tswv yim no tsis tau siv rau xyoo?

Nws zoo nkaus li cov ntawv xov xwm no tab tom nrhiav kom kaw qhov xaim uas Martin Vrijland tau ntaus hauv qab ntawm lub tshav dav hlau loj. Rau ob peb lub xyoo tam sim no kuv tau raug piav qhia li cas tawm tau xov xwm tawm. Jort Kelder thiab Alexander Klöpping tau raug tso cai nyob rau hauv qhov kev pab cuam hauv Kelder & Klöpping qhia dab tsi yog qhov sib npaug. Tsis tas li cov phiaj xwm xov tooj cua Image determiners BNR Nieuwsradio (tus neeg saib xyuas txoj haujlwm) tsis ntev los no hais txog qhov kuv tau sau txog li ntev tau. Nws yog qhov tseeb tias qhov ceeb ntshai yeej ib txwm pom thiab tias cov neeg tsim kev pab cuam yuav tsum sim ua kom tus neeg saib xyuas thiab mloog ntawm board. Koj yuav tsum tso siab rau hauv xov xwm thiab kev cai ywj pheej, vim tias tsis muaj dab tsi phem tshaj qhov mob revolting (hais lus hauv Jort qab daus).

Ntawm cov hoob kawm "daws" rau tag nrho cov no yog tias tsoom fwv thiab cov tuam txhab lag luam yuav tau sim ntxiv ib hom ntawm watermark rau movies, yog li ntawd lawv tuaj yeem tshawb xyuas qhov tseeb. Cov lus nug tsuas yog hais tias yog tsoom fwv lawv tus kheej tau siv cov xov xwm fake rau ntau xyoo los thawb tawm kev cai thiab ua si rau cov tib neeg txawm tias tsis yog txoj cai watermark yog qhov tseeb. Yog tus neeg tua neeg mus xyeej nws cov nqaij? Tsis yog, ntawm chav kawm tsis. Tag nrho cov xov xwm los ntawm John de Mol, NOS, Lub Telegraaf thiab yog li ntawd yeej ib txwm ua tiav kev ntseeg siab thiab ncaj ncees! Hnoos. Koj puas xav tias John de Mol yuav tshwm sim hauv TV hnub no los sis tag kis mus hais tias: "Thov txim lis thiab gentlemen, Kuv tau ua cov xov xwm fake nrog txhua tus TV studios thiab software uas kuv muaj ntawm kuv pov tseg. Kuv tau qhia koj nrog cov xov xwm fake thiab ua si nrog cov hauj lwm puas siab ntsws ntawm tus nqi ntawm lub lauj kaub thiab sau kuv lub hnab"? Tsis yog, ntawm chav kawm tsis. Thiab tau kawg koj yuav tsum ntseeg txoj hauv kev tshaj tawm thiab hauv tsoomfwv, vim lwm tus neeg koj yuav tsum ntseeg siab? Nyeem no...

Cov ntawv thov tau tob tshaj plaws:

  1. deepfake kev tawm profiles
  2. duab thiab yeeb yaj duab los ntawm yav tas los nrog rau tsev neeg thiab cov phooj ywg
  3. nyob nrog kev sib tham nrog ib tug neeg tsis yog-neeg
  4. cov duab ntawm cov koob yees duab kev ruaj ntseg
  5. video ua pov thawj nyob rau hauv cov xov xwm (fake xov xwm tsim tawm)
  6. thiab ua li ntawd

    Cov thawj coj ntawm lub ntiaj teb tseem siv tib hom kev kawm. Nyob rau hauv cov nqe lus ntawm technology, lawv ua raws li nrog lub sij hawm. Yav tag los koj tuaj yeem tsav cov pab pawg neeg vwm nrog ib daim duab uas tsis yog-ib qho. Lawv ib txwm ua ib kauj ruam ua ntej peb los ntawm kev tswj keeb kwm nrog kev pab ntawm phau ntawv yob thiab zoo li no.

    Nyob rau hauv lub dhau los muaj kuj Martin lub uas taw qhia rau cov neeg hais tias lawv raug fooled.

    Qhov phem tshaj plaws yog tias tib neeg niaj hnub xav tias lawv txawj ntse dua peb cov neeg ua ntej. Kuv tsis xav tias ntau tau pauv lawm, peb tseem qhev ua haujlwm rau lawv tus kheej rau ib qho thiab haus.

    Lawv siv los hais "koj tsis tas yuav ntseeg txhua yam lawv hais"

    Hnub no peb hais "koj tsis txhob ntseeg txhua yam koj pom"
