Butterflies May Prevent Forged Currency

According to a Daily Mail report, researchers at Cambridge University have discovered a way to duplicate some of the intricate optical signatures found in butterfly wings for use as an encryption method. This complex structure found in butterfly wings allows butterflies to appear one color to other butterflies, but a different color to their predators and other species. By recreating this technology, scientists have been able to produce optical signatures that change color based on how they are viewed.

One practical use of this new technology is to help deter the forgery of documents such as bank notes. Due to its high complexity and difficulty to reproduce, the use of this technology would make it much more challenging for counterfeiters to forge documents that utilize it as an anti-duplication measure.

Essentially, the optical signature would cause marking(s) on the document to change appearance when viewed under different lighting conditions.
