Introduce fingerprints and lay the foundation for understanding their basics and applications in various identification contexts.
Trace the evolution of fingerprints, define fingerprint patterns, and the three types: loops, arches, whorls, while explaining Henry’s classification and early collection procedures.
Fingerprints are unique, enduring identifiers with characteristics that make identical prints virtually impossible; the lecture covers loop, whorl, and arch patterns, deltas, and cores.
Explore the single digit fingerprint classification by Baguley for rapid crime scene print identification and note Batley among the single digit methods preceding the ten-digit system.
Learn Henry's ten digit fingerprint classification system, covering primary numerical and non-numerical patterns, the numerator and denominator finger order, and the major, secondary, subsecondary, final, and e classifications.
Learn physical and chemical methods to detect latent fingerprints, including powder development, iodine fuming, and magnetic brush techniques on porous and non-porous surfaces.
Apply chemical methods to develop latent fingerprints, including silver nitrate producing silver chloride, ninhydrin for amino acids, osmium tetroxide, and cyanoacrylate fuming on various surfaces.
Explore automated fingerprint identification systems (AFIS) and FISA, detailing digital encoding of minutiae, high-speed matching, cross-system compatibility challenges, and examiner verification in modern life scan workflows.
Explore digital imaging techniques to enhance latent fingerprint images, including grayscale conversion, filtering, frequency analysis (ffe/ffp), color background removal, and the compare and zone tools to match ridge features.
INTRODUCTION
A fingerprint is an impression left by the friction ridges of a human finger. During this course, many aspects of the course are to be taken such as forensics, records, developmental techniques and computer aided techniques. People who have clever mind, take interest in day to day incidents and have an interest to go into the depth of the matter are good to go for this course.
COURSE DESCRIPTION
This course emphasizes the basic information of fingerprints, its principles and their role in investigations and how to analyze fingerprints of an individual through comparison and identification. The Henry's classification system is given emphasis in relation with the identification of individuals through fingerprints. Several methods of developing fingerprints are also explained thoroughly. Specifically, it focuses on fingerprint recording, developing of latent fingerprints and identification and classification of fingerprints for the purpose of presentation in the court of law. This course also includes an insight of AFIS and digital imaging enhancement technique for fingerprints.
COURSE OUTCOMES
After completing the course, the student must be able to:
relate the principles of fingerprint to personal identification and criminal investigation
explain about the history and evolution of fingerprints in forensics
acquire knowledge about the science of fingerprints and different types and patterns of fingerprints.
different classification systems
demonstrate competence in collecting known and unknown samples fingerprints as evidence using various developmental techniques and also identify the individual characteristics by comparing both the prints.
explain about recent advancement in the field of fingerprint identification system such as AFIS, Digital Imaging, etc.
