Prior to the modification by the FBI, the Henry system consisted of 4 classifications system. The American Biology Teacher, a nationally recognized journal, offers articles on recent advances in biology and life science, instructional activities for the classroom and laboratory, and interdisciplinary programs. From the analysis, it is observed that the ridge count and the fingertip size of the fingerprints are more for male than female. In the proposed method, instead of considering counting only between the core and delta, an effort is taken to count the ridges of the entire fingertip. The low point on a ridge is called a col or saddle. A ridge count between any two points on the fingerprint is defined as the number of ridges running between the two points on the fingerprint. Apart from loop and whorl pattern, if there is any another the number assigned to it is 0. It is demonstrated that the males have a higher ridge breadth than females [1]. In whorl pattern, ridge tracing will be done. ridge counting or tracing performed for loops and whorls, respectively that are present on the index, middle, and ring fingers.
