Resilience of Biometric Authentication of Voice Assistants against Deepfakes Šandor, Oskar ; Firc, Anton (referee) ; Malinka, Kamil (advisor) S rozvojom technológie deepfake sa napodobňovanie hlasu cudzích ľudí stalo oveľa jednoduchším. Na napodobnenie hlasu osoby a prípadné oklamanie človeka alebo stroja už nie je potrebné mať profesionálneho imitátora. Útočníkom stačí niekoľko nahrávok hlasu osoby bez ohľadu na obsah, aby vytvorili klon hlasu za pomoci online nástrojov. V takom prípade dokáže útočník vytvoriť syntetické nahrávky s obsahom, ktorý daná osoba možno nikdy nepovedala. Tieto nahrávky sa dajú zneužiť napríklad na neoprávnené používanie hlasových asistentov. Cieľom tejto práce je zistiť, či hlasoví asistenti dokážu rozpoznať tieto nahrávky. Vykonané experimenty ukazujú, že deepfakes vytvorené v priebehu niekoľkých minút dokážu obísť schopnosť hlasových asistentov rozpoznať hovoriaceho a môžu byť použité na uskutočnenie viacerých útokov.
