| Abstract: | Poroscopy is the specialized study of sweat pores found on the papillary ridges of the skin. However, the science of poroscopy is not being used to its full potential. The present study was conducted with the goal to assess the effect of immersing hand in water at various temperatures i.e., room temperature (20–30 °C), hot temperature (40–50 °C), and cold temperature (0–10 °C), for 1, 5 and 10 min, on the reproducibility of pore microfeatures namely, area, inter-distance, and angle, in an attempt to demonstrate their reliability in fingerprint matching. As far as the authors are aware, no prior research has attempted to evaluate the impact of immersing hand in water, at different temperatures, on the reproducibility of third level details. Statistical analysis of data revealed that pore inter-distance and angle were reproducible in nature thereby, highlighting their significance in fingerprint matching. |
