Atpresent,deepfakesareoneofthemostadvancedformsofsyntheticallygeneratedmediaanditispredictedthattheycouldaccountforupto90%oftheonlineavailablecontentintheupcomingyears.3

Oneofthefirsttechnologiesthatproduceddeepfake-likeresultswastheVideoRewriteProgramin1997,4whichautomatedfacialreanimationinvideos.Basedonasimilarconcept,theGenerativeAdversarialNetwork5(“GAN”)wasintroducedin2014,whichwasfurtherimprovisedbyNvidia6in2017toproducegoodqualityforgedimages.

WiththeGANalgorithmsslowlycatchingtraction,laterin2017,theterm“deepfakes”wascoinedwhenanunidentifieduseronthesocialmediaplatformReddithaddevelopedanalgorithm,7thattheuserusedtotransposecelebrityfacesontopornographiccontent.8Thelikenessofthecelebritieswassuperimposedinthepornographiccontenttotheextentthatitappearedtobetrue.Owingtothenatureofthecontentbeingshared,itinstantlybecameviralandwidespread.Theunidentifieduserusedtogowiththeusernamedeepfakes,andhence,thetechnologycametobecommonlyreferredtoasdeepfaketechnology.

Essentially,deepfakesreferto“fake”contentthatiscreatedusing“deeplearning”technology.9Apartfromthisoversimplifiedmeaningofdeepfakes,ithasalsobeendefinedbytheOxfordUniversityPress10as:“avideoofapersoninwhichtheirfaceorbodyhasbeendigitallyalteredsothattheyappeartobesomeoneelse,typicallyusedmaliciouslyortospreadfalseinformation.”WiththeadvancesinAI-synthesizedtechniques,deepfakesarenowalsocapableofcreatinghighlyrealisticallysoundedvoices.11

A.Meaning

Deepfakesaretypicallyunderstoodtobemanipulatedmedia.1However,tojustsaythatdeepfakesaresynthesizedmediacreatedbyusingidentity-swappingalgorithmswouldnotdojusticetothedepthofthisconcept.Inaworldwhereeveryimageorvideoontheinternetmaybealteredtosomedegreeusingdeeplearning,itbecomesdifficulttoagreeonacommondefinitionofdeepfakessincethelinewhereapictureorvideobecomes“manipulated”or“fake”isblurred.

Nevertheless,theusageofdeeplearningtechnologytoproducefakecontentcontributedtowardstheportmanteau–Deepfakes.2Eventhoughthereisnogloballyagreedupondefinitionfordeepfakes,theycametobe

understoodconventionallyas“fakeimagescreatedbyanadvancedimageediting,deeplearningsoftware.”3
