A team of researchers from the Weizmann Institute of Science in Israel has discovered that a person’s breath can serve as a unique identifier, achieving an impressive 96.8% accuracy in recognizing individuals through a "respiratory fingerprint." Published on June 14, 2025, the study highlights a novel approach to biometric identification based on breathing patterns.
The experiment involved 97 volunteers who used sensors to analyze 24 distinct breathing parameters. Initial results showed a 43% accuracy rate in identifying users within one hour, a figure that surged to nearly 97% over a 24-hour period. This remarkable improvement demonstrates the potential of long-term data collection in refining the technology.
The study also revealed that breathing characteristics are closely linked to physiological and psychological factors, such as body mass index and anxiety levels. These findings suggest that respiratory patterns could offer insights beyond identification, potentially aiding in health assessments.

Researchers believe this breakthrough could revolutionize respiratory therapies and open new avenues in disease diagnosis and treatment. “We can explore how specific breathing patterns might predict various diseases and whether altering those patterns could help treat conditions,” said a lead scientist. This innovative research promises to enhance both security applications and medical advancements in the near future.
