Nie je to v\u00fdstri\u017eok z dystopick\u00e9ho rom\u00e1nu, ale s\u00fa\u010dasn\u00e1 realita.

Ako sa to stalo?<\/h3>\n

V\u010faka obrovsk\u00e9mu pokroku v oblasti generat\u00edvnej AI<\/a> sa deepfaky stali tak presn\u00fdmi, \u017ee sa stratili aj posledn\u00e9 vizu\u00e1lne \u201echyby\u201c, ktor\u00e9 ich kedysi prezr\u00e1dzali \u2013 neprirodzen\u00e9 pohyby o\u010d\u00ed, zle synchronizovan\u00fd hlas, slab\u00e1 mimika.<\/p>\n

Modern\u00e9 modely ako GANy (generative adversarial networks) \u010di diffusion-based algoritmy u\u017e generuj\u00fa vizu\u00e1lne v\u00fdstupy s takou presnos\u0165ou, \u017ee len minim\u00e1lne rozdiely v mikropohyboch tv\u00e1re \u010di o\u010d\u00ed \u2013 a to len niekedy \u2013 ich m\u00f4\u017eu prezradi\u0165. A ke\u010f je video komprimovan\u00e9 alebo zdie\u013ean\u00e9 cez soci\u00e1lne siete, aj tie mizn\u00fa.<\/p>\n

Ak\u00e9 to m\u00e1 d\u00f4sledky?<\/h3>\n

    Z\u00e1nik vizu\u00e1lnej d\u00f4very<\/strong> \u2013 ak u\u017e nevieme veri\u0165 tomu, \u010do vid\u00edme, \u010do zost\u00e1va? Doteraz bol vizu\u00e1lny d\u00f4kaz pova\u017eovan\u00fd za jeden z najsilnej\u0161\u00edch. Teraz m\u00f4\u017ee by\u0165 len v\u00fdsledkom p\u00e1r kliknut\u00ed.<\/p>\n<\/li>\n

    Masov\u00e9 dezinform\u00e1cie<\/strong> \u2013 deepfaky sa st\u00e1vaj\u00fa zbra\u0148ou: ovplyv\u0148uj\u00fa vo\u013eby, vytv\u00e1raj\u00fa falo\u0161n\u00e9 \u0161kand\u00e1ly, \u00fato\u010dia na reput\u00e1ciu jednotlivcov aj firiem.<\/p>\n<\/li>\n

    \u00c1no, ale len \u010diasto\u010dne. Vedci a v\u00fdvoj\u00e1ri vytv\u00e1raj\u00fa \u010doraz sofistikovanej\u0161ie n\u00e1stroje na odha\u013eovanie deepfakov. Sleduj\u00fa pohyb o\u010d\u00ed, deform\u00e1cie obrazu, mikroexpresie, alebo dokonca biometrick\u00e9 rytmy (napr. frekvenciu \u017emurkania). Vznikaj\u00fa aj hybridn\u00e9 pr\u00edstupy, ktor\u00e9 sp\u00e1jaj\u00fa AI a \u013eudsk\u00fd doh\u013ead.<\/p>\n

    No aj tieto n\u00e1stroje maj\u00fa slabiny. Funguj\u00fa dobre v kontrolovanom prostred\u00ed, no \u010dasto zlyh\u00e1vaj\u00fa pri be\u017enom pou\u017eit\u00ed \u2013 najm\u00e4 ak je obsah komprimovan\u00fd alebo upraven\u00fd.<\/p>\n

    \u010coraz viac sa zd\u00e1, \u017ee budeme musie\u0165 predefinova\u0165 pojem d\u00f4very<\/strong>. Nesta\u010d\u00ed u\u017e \u201evidie\u0165 na vlastn\u00e9 o\u010di\u201c.

    M\u00e9di\u00e1, \u0161koly a spolo\u010dnosti bud\u00fa musie\u0165 za\u010da\u0165 u\u010di\u0165 nov\u00fa formu gramotnosti \u2013 \u201evizu\u00e1lnu sebaobranu\u201c. Namiesto slepej d\u00f4very vo vizu\u00e1lny materi\u00e1l sa budeme musie\u0165 p\u00fdta\u0165: Odkia\u013e to je? Kto to vytvoril? Je to overen\u00e9?<\/p>\n

    Z\u00e1ver<\/h3>\n

    Vstupujeme do \u00e9ry, ke\u010f sa na\u0161e o\u010di m\u00f4\u017eu sta\u0165 na\u0161\u00edm najv\u00e4\u010d\u0161\u00edm omylom. Realita je u\u017e nie to, \u010do vid\u00edme, ale to, \u010do vieme a dok\u00e1\u017eeme overi\u0165.
