**Summary:**

A recent study has found that the wrinkle patterns that form on fingertips after prolonged exposure to water are unique to each individual, similar to fingerprints. Researchers immersed hands in warm water, mapping the resulting wrinkles. The patterns remained consistent for each individual across multiple trials, suggesting a potential new biometric identifier. The uniqueness likely stems from the unique distribution of blood vessels beneath the skin of each person. This discovery could be particularly useful for identifying individuals, especially in situations where fingerprints are compromised, such as identifying bodies recovered from water.

**Unique Finger Wrinkle Patterns Could Be New Biometric Identifier**

**Bengaluru, India – May 27, 2025** – Forget fingerprints; the key to unlocking your identity might lie in the wrinkles that form on your fingertips after a long bath. A new study published in the *Journal of the Mechanical Behavior of Biomedical Materials* has revealed that these wrinkle patterns are surprisingly unique to each individual, opening up possibilities for a new form of biometric identification.

Researchers at Binghamton University, led by associate professor Guy German and graduate student Rachel Laytin, discovered that the patterns created by water-induced wrinkles are consistent for each person, even when retested. The team immersed participants’ hands in 40º C water for 30 minutes and mapped the resulting wrinkles. The patterns formed proved to be near consistent.

“We found that the pattern is the same for an individual regardless of how many times it is forced to wrinkle,” said German.

The science behind the wrinkling involves nerve signals causing blood vessels in the fingertips to constrict, leading to the skin contracting. The uniqueness of the wrinkle pattern likely stems from the unique distribution and size of blood vessels beneath the skin for each individual.

“The size and distribution of blood vessels is well known to vary across individuals,” German explained.

This discovery could have significant implications for law enforcement and disaster relief. According to the article, the unique wrinkle pattern could prove especially beneficial when attempting to identify bodies recovered from water, where fingerprints may be unusable.
The discovery also has benefits in being accessible to use in victims from floods and tsunamis.

“If the wrinkles can be used to identify people, it could be used in place of fingerprints, too, especially when law enforcement officials have to identify cadavers found in water, and to quickly identify victims following water-based disasters like floods and tsunamis.”

While a direct correlation between wrinkle patterns and fingerprints has yet to be established, researchers suggest that wrinkle mapping could be an additional layer of biometric data collected by government agencies. This could lead to better security, with fingerprint and finger wrinkle mapping being a new level of security.
