When Deepfakes Beat Our Eyes: Physical Layer Forensics Takes Center Stage

Deepfakes have evolved beyond human detection capabilities, making visual and auditory judgment unreliable for authenticity verification. Physical layer forensics addresses this by analyzing minute deviations from natural physics in digital media—from skin blood flow inconsistencies to synthetic voice tremors—that AI systems can identify. This technological shift could reshape digital trust infrastructure and become critical for combating misinformation in the coming years.
