Njenge siya phambili ekuqaleni kukaJuni, kule nyanga i- I-OpenExpo 2021, umcimbi wezobuchwepheshe kulo nyaka ozosebenzisa ubuchwepheshe kancane, ngoba wawuzobonakala konke. Bekuvele kwaziwa ukuthi kubo bonke abathandi bezobuchwepheshe kuzoba mnandi, kepha thina esikwazile ukukufakaza besingacabangi ukuthi bazobhekana nezihloko okuthi, yize kuyiqiniso ukuthi sebephakathi kwethu, hhayi sonke zisebenzise noma uzicabangele.
Into ethakazelisa kakhulu okuxoxwe ngayo kwi-OpenExpo yalo nyaka yingqungquthela eyanikezwa uChema Alonso, odumile, ngokwengxenye, yokubhekana nokuphepha kwe-cyber noma izindaba zokuphepha kuzo zonke izinhlobo zemishini. Futhi kungukuthi lawo mavidiyo abiziwe I-DeepFakes ukuthi sonke sibona kumanethiwekhi ukuthi okuthile okuhlekisayo kungaba yingozi kanjani empeleni. Futhi cha, asikhulumi ngeqiniso lokuthi lapho ngifaka ividiyo yesigcawu esivela ku-movie bese ngifaka ubuso bami kumlingisi, ngiyisigebengu noma ngenza okuthile okungalungile, kepha ubuchwepheshe obukulandelayo, i okuthuthukile kakhulu, kungaba yinkinga kokubili kwezokuphepha (ukuzenza ongeyena) nokusabalalisa imininingwane engamanga (Izindaba Zomgunyathi).
I-OpenExpo iveza ukuthi sekunama-DeepFakes acishe abe ngu-50.000 XNUMX ajikelezayo
Ngenhlanhla, kwenzeka izinto ezimbili: eyokuqala ukuthi iningi lalawo maDeepFakes, kufika kuma-96% enzelwa ukulayishwa ividiyo enezithombe zocansi lapho sibona khona umlingisi noma umlingisi odumile esenzweni. Amawebhusayithi ahlonishwa kakhulu awaqeda ngokushesha lapho ewathola, kepha kuba nzima uma efaka cishe amavidiyo ayi-1000 ngenyanga. Futhi lokhu kutholwa kungenye into enhle eyenzekayo noma ezokwenzeka: kunezindlela esezikhona zokuthola i-DeepFakes ngokuhlaziywa kwe-forensic kwezithombe nokukhishwa kwedatha yezinto eziphilayo kubo, lokho nokuthi abantu bayaqashwa ukuze benze uphenyo.
Yize udaba lwezokuphepha lubalulekile, kubalulekile futhi ukuthi "singathengi" noma "sithenge" noma yiziphi izindaba esizibonayo. Ngalesi sizathu, uChema Alonso nethimba lakhe le-Ideas Locas bakhe i-a i-plugin ye-chrome (futhi iyahambisana, kithina esingayithandi iGoogle kakhulu) eyenza uphenyo lwesayensi ezine ukuthola i-DeepFakes:
- I-FaceForensics ++: okwenziwa yilokhu kuhlaziywa ngokuyisisekelo yilokho esikubonayo kumamuvi, kepha esikhundleni sokuqhathanisa ubuso noma izinyawo, kuqhathanisa i-DeepFakes ngokuya ngemodeli eqeqeshwe ku-database yayo.
- Ukudalula Amavidiyo e-DeepFake Ngokuthola Izinto Zobuso Ezisongelayo Zobuso: Lokhu kuzosebenzisa iphuzu elibuthakathaka le-DeepFakes yamanje, njengokulungiswa okuphansi kwezithombe, ukuthola izinkomba ezidingekayo.
- Ukudalula ama-Fake ajulile Kusetshenziswa Okungahambisani Nekhanda: Angiyona i-AI noma yini enjengaleyo, kepha kwesinye isikhathi ngibeka ubuso ngaphezulu kobuso. Kunzima, futhi amaphutha afanayo enziwa ngabantu enziwa yimishini. Amaphutha abantu atholwa ngabantu, kanti lawo enziwa yimishini atholwa yimishini. Ngokuyisisekelo, okubonwa "ngumshini omuhle" ukuthi ubuso abuphelele emzimbeni wakhe omusha, ikakhulukazi ekuhambeni ngezilinganiso ezintathu.
- Izithombe ezikhiqizwe yi-CNN kulula ukuzibona kalula… okwamanje- Izithombe ezenziwe ngamamodeli we-generator ahlukile we-CNN ayi-11 anezici ezikhetheke kakhulu, ngakho-ke ukwahlukanisa kungenza kahle kwezinye izakhiwo. Izithombe zamanje ezikhiqizwe yi-CNN zinamaphutha ahlelekile, ngakho-ke azikho ngokoqobo.
"Okwamanje" kusho ukuthi kuzoba nezinkinga ngokuzayo
Ephuzwini lokugcina lokuthi i-plugin yenzani (noma izokwenzani) ichaza nokuthi yini uChema akuchaze kamuva: i-DeepFakes isivele iphakathi kwethu futhi kufanele sikulungele okungenzeka kwenzeke. Futhi okuzokwenzeka ngokuqinisekile yilokho izinhlelo zokwenziwa kokuqukethwe okungamanga zizothuthuka, futhi okuningi uma sibheka ukuthi kuzosetshenziswa ubuhlakani bokufunda nokufunda okujulile, ngakho-ke kufanele ugoqe imikhono yakho futhi usebenze ukuze ube kulo msebenzi. I-X video ingaba wuhlupho kumuntu odumile kuphela, futhi esikwenzayo ngomakhalekhukhwini akunangozi ngokuphelele, kepha ukubeka ubuso bethu kumuntu owenza icala, ngokwesibonelo, lokho kuhluke ngokuphelele.
Ngokuqondene ne i-plugin eshiwo ngu-Alonso, kusazodingeka silinde ukukwazi ukuyisebenzisa, kepha ngicabanga ukuthi kuzoba "okumele ube nakho" kulabo abafuna ukwaziswa futhi bangakholelwa kukho konke.
Futhi yize lokhu bekuthakazelisa kakhulu kulo mcimbi, kungenxa yokuthi ubuchwepheshe obusha sha, obuyingxenye yezimpilo zethu futhi sisebenzela ukuwuthuthukisa, ohlangothini lwabadali nalabo abafuna ukwambula lo mbumbulu. Kepha i-OpenExpo 2021 nayo ikhulume nge I-GovTech, okungukuthi, ubuchwepheshe obusetshenziswa ohulumeni, ubuchwepheshe obuhlobene nemfundo noma i-EdTech, obubalulekile ngaso sonke isikhathi futhi ngaphezulu ngezikhathi lapho ukushiya ikhaya akuwona umqondo omuhle, ukusimama, imvelo, ibhizinisi lomculo kanye nokwenza ikhompiyutha kanye nokufinyeleleka. I-OpenExpo ingu umcimbi ngokuphelele, futhi uma uphuthelwe eyodwa kule nyanga, ngonyaka ozayo bazobuya nokuningi, sethemba ukuthi sebephila vele.
