Deepfakes are realistic-looking videos or audio recordings that use artificial intelligence to create altered content. They can make it appear as if someone is saying or doing something they never actually did. This technology relies on deep learning algorithms to analyze and replicate facial expressions, voice patterns, and other characteristics. While deepfakes can be used for entertainment, such as in movies or parodies, they also raise concerns about misinformation and privacy. For instance, they can be misused to create fake news or manipulate public opinion, posing challenges for individuals and society in distinguishing between real and fabricated content.
