Nzira yekuziva sei zvakadzika uye kudzivirira nhau dzenhema

Echo Dot Smart Mutauri

pandakanzwa nezvazvo dzikadzika kekutanga ndakanakidzwa nepfungwa yehungwaru hwekugadzira kudzokorora chiso chemunhu pavhidhiyo. Asi zvakabva zvava pachena kuti michina yacho yaigona kuva nengozi. Deepfakes akashandiswa pakuita zvematongerwo enyika, semuenzaniso. Kana zvakadaro, zvinogoneka here kutaura kana vhidhiyo isiri yemanyepo?

Dambudziko rinowedzera kukura kana tikafunga kuti kune akati wandei marudzi ezvakadzama. Iyo inonyanya kuzivikanwa inoshandisa mufananidzo wemunhu kugadzira vhidhiyo mavanotaura chirevo chisina kumbovapo. Asi vamwe vanogadzira fake profiles pasocial network kana kutevedzera manzwi (deepvoices), semuenzaniso.

Zvisinei nerudzi, njodzi yekuparadzira manyepo ezvinyorwa kana nhau dzemanyepo kuburikidza nehunyanzvi hwakakura. Ziva, mumitsetse mishoma inotevera, zvaungaita kuti uzvidzivirire panjodzi idzi.

Chii chiri dzikadzika ?

Ipo pano mukati TechnoBreak Iwe unogona kuwana tsananguro yakadzama nezve deepfakes. Asi heino tsananguro yekukurumidza: deepfake inyanzvi inoshandisa kudzidza kwakadzama (pfungwa ine chekuita nehungwaru hwekugadzira) kushandura zviso zvemunhu kana kutaura mumifananidzo nemavhidhiyo.

Muzviitiko zvakawanda, kunyengedza uku kunoitwa zvakanaka zvekuti zvinonetsa kuziva yakadzika. Izvo zvine ngozi. Kana, kune rumwe rutivi, zvinonakidza kufungidzira Mona Lisa (kubva pamufananidzo waLeonardo da Vinci) achitaura muvhidhiyo achishandisa nzira, kune rumwe rutivi, deepfakes inogona kushandiswa kuparadzira nhau dzenhema pamagariro evanhu, pakati pezvimwe zvinetso. .

Pane chikonzero chakanaka cheizvi: michina inogadzira zvakadzika yakashanduka nekukurumidza. Kuti ndikupe iwe zano, GAN-mhando neural network (iwe uchaona izvo iwo anosanganisirwa mune ino chinyorwa) akaratidzwa kuti anoshanda zvakanyanya murudzi urwu rwechiitiko.

Yakabatana nemaitiro ekuumba izwi, manomapulations evhidhiyo akavakirwa pakadzika fakes ave achiwedzera kuwanda pasocial network kana masevhisi akadai seWhatsApp kana Telegraph. Mazhinji emavhidhiyo emanyepo aya ane chinangwa chekunyadzisa vanhu kana kuti mitsara yemanyepo kune vezvematongerwo enyika.

Heino muenzaniso wezvakadzama zvinoratidza mutungamiri weUkraine achizvipira kuRussia. Imwe, inoratidzwa pazasi, inoisa chiso chemutambi Tom Cruise pane mumwe munhu.

Mazano ekuona deepfakes pasina kuve nyanzvi

Fernando Rodrigues de Oliveira, anozivikanwa zviri nani saFernando 3D, akagadzira FaceFactory pamwe naBruno Sartori. Iyo kambani inoshandisa hungwaru hwekunyepedzera kune "yakanaka yakadzika fake" mapurojekiti, ekushandisa mumabhaisikopo anonzi, semuenzaniso. Zvekuti vanosarudza kudaidza iyo nzira "synthetic media".

Pasinei neshoko reunyanzvi, chokwadi ndechekuti Fernando anonzwisisa nyaya yacho. Muhurukuro yedu, akatsanangura kuti deepfakes "inodzidza" nekufamba kwenguva, shure kwezvose, inobva pauchenjeri hwekugadzira. Ichi ndicho chikonzero nei zvichiwedzera kuoma kuona vhidhiyo inogadziriswa kuburikidza nehunyanzvi.

Gadzirisa maziso nemuromo

Zvisinei neizvozvo, pane mashoma mashoma aunogona kushandisa kufumura yakadzika, anodaro Fernando. Imwe yacho ndeyekutarisa chitarisiko chemunhu anoonekwa muvhidhiyo. “Ziso rinogona kurasika zvishoma,” anotsanangura kudaro. Zvinoita sokuti munhu wacho haasi kutarisa pane chimwe chinhu kana kamera.

Zvakare maererano naFernando, kuteerera mafambiro emuromo kana chiso pachacho kunobatsirawo. Mukuita uku, unogona kuona mafambiro asiri emusikirwo, senge kuvhurika kwemiromo kuti utaure rimwe izwi.

Isa saizvozvo, zvinonzwika nyore. Hazvisizvo. Fernando anoyambira kuti zvakadzika zvanhasi zvine chokwadi zvakanyanya kupfuura izvo zvakagadzirwa makore matatu kana mana apfuura nekuda kwekushanduka kwehungwaru hwekugadzira. Ndosaka kudzivirira kwedu kwakanakisa nhasi kuri kutarisisa kune izvo.

Kutarisa kune zvakadzama kuona deepfake

Kupfupisa, heino runyorwa rwehunhu hunoiswa naKaspersky sehunosimudzira mavhidhiyo emanyepo (ona kuti mamwe acho anopindirana nezano raFernando):

  • kufamba kamwe kamwe
  • mwenje wechiitiko unoshanduka kubva kune furemu kuenda kune furemu
  • kuchinja kweganda
  • maziso anoshamisa anobwaira kana kusabwaira
  • miromo haina kupindirana nekutaura
  • zvinhu zvedhijitari (zvigadzirwa) mumufananidzo

Pane chero software inoona deepfake?

Zvingave zvakanaka, asi zvisati zvaitika. Kwete kuti inoshanda nemazvo. Nekudaro, pane zvatove nemabasa munzira iyi. Fernando anotora, semuenzaniso, ongororo ye Facebook yekuona zvakadzika kuburikidza nereverse engineering. Asi iyi ipurojekiti isingagone kushandiswa parizvino.

Chimwe chezvikonzero zvekuoma kwakadai chiri mune inonzi maGANs (Generative Adversarial Networks). Nenzira iyi, imwe sisitimu inomhan'arwa neimwe kuti ibudise inogutsa yakadzika fake inogoneka.

Zvichitsanangurwa muchidimbu, GAN inoshanda seizvi: chishandiso chakavakirwa paneural network chinoburitsa zviuru kana mamirioni ekugadziridzwa kwemufananidzo wechiso uye chinoaendesa kune yechipiri meshini inoedza kuona kana kutevedzana kuri kwenhema. Kana iyo yekupedzisira ikasasvika pamhedzisiro yechokwadi, iyo deepfake inogadzirwa.

Sezvo kudyidzana pakati peGAN kuri kukurumidza uye kunoda kuyedza kwakawanda, kuziva "digital clone" ibasa riri kuramba richinetsa. Asi hazvigoneki. Kana iwe ukatevera mazano ari pamusoro apa, iwe uchava nemukana wakanaka wekubudirira.

Zvichakadaro, kuferefeta kuri kuyedza kutsvaga nzira dzekusaziva chete mavhidhiyo emanyepo, asiwo kudzivirira kusikwa kwavo kuburikidza nemaitiro ekusimbisa. Imwe ongororo inotofunga nezve kushandiswa kwe blockchain nechikonzero ichi, sezvo tekinoroji inoshanda nenzira yakasarudzika uye inonyatso shanda pakurwisa kunyengera.

Kwatiri isu vanhuwo zvavo, Fernando 3D inopa imwe matipi yekuziva zvakadzika fakes: siya kusavimbika mita nguva dzose. Kana vhidhiyo ikaratidza munhu achitaura zvisinganzwisisike, zvisiri mumutsara, kana manyemwe, zviri nani kuti utsvage zvakawanda nezvazvo usati wamhanyira kumhedziso.
