deepfake
Meaning: A synthetic media file, typically a video or audio recording, in which a person's face, voice, or actions are convincingly replaced or fabricated using artificial intelligence and deep learning technology.
Deepfakes represent one of the most concerning developments in digital misinformation. The technology uses neural networks to map one person's face onto another's body in video, or to clone someone's voice convincingly. While there are legitimate creative uses (film special effects, accessibility), deepfakes pose serious threats to democracy, privacy, and trust. The UK has begun legislating against malicious deepfakes, particularly those involving non-consensual intimate imagery.
Examples
- The deepfake video of the politician appeared so realistic that it was shared thousands of times before being identified as fabricated. 那段政客的深度伪造视频逼真到被分享了数千次后才被识别为伪造。El vídeo deepfake del político parecía tan realista que fue compartido miles de veces antes de ser identificado como fabricado.その政治家のディープフェイク動画は非常にリアルに見え、偽造と判明するまでに何千回もシェアされました。그 정치인의 딥페이크 영상은 너무나 사실적으로 보여서, 위조로 밝혀지기 전에 수천 번이나 공유되었습니다.
- Researchers are developing tools to detect deepfakes by analysing subtle inconsistencies in lighting and facial movement. 研究人员正在开发通过分析光线和面部运动中的细微不一致来检测深度伪造的工具。Los investigadores están desarrollando herramientas para detectar deepfakes analizando inconsistencias sutiles en la iluminación y el movimiento facial.研究者たちは、照明や顔の動きの微妙な不整合を分析することでディープフェイクを検出するツールを開発しています。연구자들은 조명과 얼굴 움직임의 미세한 불일치를 분석하여 딥페이크를 탐지하는 도구를 개발하고 있습니다.
- The rise of deepfakes has raised urgent questions about how we verify the authenticity of digital media. 深度伪造的兴起引发了关于如何验证数字媒体真实性的紧迫问题。El auge de los deepfakes ha planteado preguntas urgentes sobre cómo verificar la autenticidad de los contenidos digitales.ディープフェイクの台頭は、デジタルメディアの信頼性をどのように検証するかという緊急の問題を提起しています。딥페이크의 등장은 디지털 미디어의 진위를 어떻게 검증할 것인가라는 시급한 문제를 제기하고 있습니다.
