Personal identification through the comparison of the impressions of sweat pores present on friction ridges of palmar and plantar surfaces is called as Poroscopy. The present study was conducted to find out the similarities in the pores in respect to the position (middle or periphery) and frequency (per unit length and per unit area) of the pores present on the friction ridges of the finger of an individual. The findings showed that there existed no relationship between the position and number of pores occurring of pores per unit length and per unit area. However, a significant correlation existed between the number of pores per unit length and per unit area of the two fingers i.e, Index and Ring finger. But there existed no correlation between the Thumb – Index and Thumb – Ring Finger.
