Deepfakes are now replicating heartbeats

To summarize

• Recent studies indicate that high-fidelity deepfakes inadvertently preserve the heartbeat patterns from their original videos, compromising conventional detection techniques that depended on identifying subtle changes in skin color associated with heartbeats.
• The belief that deepfakes do not exhibit physiological cues, such as heart rate, is no longer accurate. This poses a challenge to numerous current detection systems, which may require substantial overhauls to adapt to the advancing technology.
• To successfully pinpoint high-quality deepfakes, scientists propose shifting the emphasis from merely identifying heart rate signals to examining how blood circulation is distributed across various facial areas, offering a more precise detection methodology.

Consequently, the AI models will start to replicate that.
