Since the dawn of photography,
00:00:07
image manipulation has existed,
00:00:09
but the advent of the digital
00:00:11
era has opened the way for
00:00:14
more advanced manipulations,
00:00:15
sometimes challenging our
00:00:16
perception of reality.
00:00:18
Among these innovations,
00:00:19
the deep fake stands out.
00:00:21
Particularly this term,
00:00:22
a fusion of deep learning and
00:00:25
fake refers to videos or images
00:00:28
generated by AI algorithms.
00:00:29
These creations are so convincing
00:00:31
that they can easily be
00:00:33
mistaken for genuine recordings.
00:00:36
The potential of deep fakes is vast.
00:00:38
Think of cinema icons like Marilyn
00:00:41
Monroe or James Dean who come
00:00:43
back to life to act in new films
00:00:46
or imagine world leaders giving
00:00:48
speeches they never actually made.
00:00:51
The possibilities,
00:00:52
whether creative or malicious,
00:00:53
are almost endless.
00:00:54
However,
00:00:55
these technological advances
00:00:56
raise serious ethical questions.
00:00:58
In an era where seeing was believing,
00:01:01
How can we still trust our eyes when
00:01:03
algorithms can perfectly reproduce reality?
00:01:06
The line between true and
00:01:08
false becomes blurred,
00:01:09
eroding
00:01:09
our trust in visual content.
00:01:11
The implications for privacy
00:01:13
are equally worrying.
00:01:14
Videos can be fabricated to
00:01:15
show people in situations
00:01:17
they have never experienced,
00:01:19
ruining reputations in an instant.
00:01:20
In the world of
00:01:22
media, where truth is crucial,
00:01:24
deep fakes can be used to create false
00:01:27
news, manipulate public opinion,
00:01:28
and even influence the course of elections.
00:01:31
Fortunately, the technology
00:01:32
itself offers a glimmer of hope.
00:01:34
Researchers and companies are working
00:01:36
on tools to detect deep fakes.
00:01:38
These solutions use AI to
00:01:40
analyze videos and spot anomalies
00:01:42
that betray manipulation.
00:01:44
In this evolving landscape,
00:01:45
one thing remains constant the need
00:01:48
to stay vigilant and informed.

Desde os primórdios da fotografia,
00:00:07
a manipulação de imagem existiu,
00:00:09
mas o advento do digital
00:00:11
O EEI abriu caminho para
00:00:14
manipulações mais avançadas,
00:00:15
por vezes desafiando o nosso
00:00:16
perceção da realidade.
00:00:18
Entre essas inovações,
00:00:19
o deep fake se destaca.
00:00:21
Particularmente este termo,
00:00:22
uma fusão de aprendizagem profunda e
00:00:25
fake refere-se a vídeos ou imagens
00:00:28
gerados por algoritmos de IA.
00:00:29
Estas criações são tão convincentes
00:00:31
que podem ser facilmente
00:00:33
confundido com gravações genuínas.
00:00:36
O potencial das deep fakes é vasto.
00:00:38
Pense em ícones do cinema como Marilyn
00:00:41
Monroe ou James Dean que vêm
00:00:43
De volta à vida para atuar em novos filmes
00:00:46
ou imagine líderes mundiais dando
00:00:48
discursos que nunca fizeram.
00:00:51
As possibilidades,
00:00:52
sejam eles criativos ou maliciosos,
00:00:53
são quase infinitas.
00:00:54
No entanto,
00:00:55
estes avanços tecnológicos
00:00:56
levantam sérias questões éticas.
00:00:58
Numa época em que ver era acreditar,
00:01:01
Como podemos ainda confiar nos nossos olhos quando
00:01:03
Os algoritmos podem reproduzir perfeitamente a realidade?
00:01:06
A linha entre verdadeiro e verdadeiro
00:01:08
false torna-se desfocado,
00:01:09
erosão
00:01:09
a nossa confiança no conteúdo visual.
00:01:11
As implicações para a privacidade
00:01:13
são igualmente preocupantes.
00:01:14
Os vídeos podem ser fabricados para
00:01:15
mostrar pessoas em situações
00:01:17
nunca experimentaram,
00:01:19
arruinando reputações num instante.
00:01:20
No mundo da
00:01:22
meios de comunicação social, onde a verdade é crucial,
00:01:24
Deep fakes podem ser usados para criar falsos
00:01:27
notícias, manipular a opinião pública,
00:01:28
e até influenciar o desenrolar das eleições.
00:01:31
Felizmente, a tecnologia
00:01:32
ela própria oferece um vislumbre de esperança.
00:01:34
Investigadores e empresas estão a trabalhar
00:01:36
em ferramentas para detetar deep fakes.
00:01:38
Essas soluções usam IA para
00:01:40
analisar vídeos e detetar anomalias
00:01:42
que traem a manipulação.
00:01:44
Neste cenário em evolução,
00:01:45
Uma coisa permanece constante: a necessidade
00:01:48
manter-se vigilante e informado.
