Another Move in the Deepfake Creation/Detection Arms Race
高质量深度伪造视频无意中保留了源视频的心跳模式,使传统基于皮肤颜色变化检测的方法失效。研究显示深度伪造不再缺乏生理信号如心率,需改进检测工具并转向分析面部血流分布以提高准确性。 2025-5-5 16:2:53 Author: www.schneier.com(查看原文) 阅读量:13 收藏

Deepfakes are now mimicking heartbeats

In a nutshell

  • Recent research reveals that high-quality deepfakes unintentionally retain the heartbeat patterns from their source videos, undermining traditional detection methods that relied on detecting subtle skin color changes linked to heartbeats.
  • The assumption that deepfakes lack physiological signals, such as heart rate, is no longer valid. This challenges many existing detection tools, which may need significant redesigns to keep up with the evolving technology.
  • To effectively identify high-quality deepfakes, researchers suggest shifting focus from just detecting heart rate signals to analyzing how blood flow is distributed across different facial regions, providing a more accurate detection strategy.

And the AI models will start mimicking that.
