Abstract: Objective To identify distinguishing characteristics between colored fingerprints produced by fingerprint stamps or silicone molds and those made by real fingers, and to provide a reference for accurate authentication of highly simulated forged fingerprints. Methods A combined approach incorporating morphological analysis, ninhydrin fuming, and electrostatic indentation was adopted to compare the features of colored fingerprints imprinted by fingerprint stamps, silicone molds, and real fingers under different development conditions. Results Significant characteristic differences were observed between forged fingerprints (from stamps or silicone molds) and genuine fingerprints across all three development methods: direct morphology, ninhydrin fuming, and indentation development. Conclusion Under certain conditions, the established method can effectively identify highly simulated fingerprints formed by fingerprint stamps, providing a practical technical solution for forensic institutions with limited resources. However, its effectiveness is limited in distinguishing fingerprints produced by silicone molds.
