Researchers have developed a new method for detecting fake fingerprints acquired without physical contact, utilizing paired flash and non-flash imaging. This technique enhances the visibility of material and structural properties, such as subsurface scattering and surface oils, which are crucial for distinguishing real fingerprints from various types of spoofed ones. The study also explores the limitations of this approach, including its sensitivity to imaging settings and the emergence of sophisticated fake fingerprints. AI
