Fingerprint identification is now the most reliable and widely used method of human identification. Earlier, anthropometric measurements were used to establish identity but that method lacked positiveness and was always suspect. Late in the 12th century, it was replaced by fingerprint identification of suspects, victims and innocent by-standers.
An identification through fingerprints is positive and cannot be questioned. It is the most commonly used forensic evidence all over the world. It has outperformed even DNA identification. The method has, over the years, established its superiority and continues to expand. Besides, fingerprints can be preserved. You may get to the perpetrator of a crime simply by matching fingerprints.
Crime apart, there are several other areas where personal identification could be required. Passports, certificates, testimonials, legal documents, cards etc. require positive identification and fingerprints often come into use.
A crime scene investigation could field a variety of fingerprints requiring identification. These can be matched with already available fingerprints. Technique is now available to lift fingerprints from all sorts of surfaces and impossible places. Dim fingerprints can be highlighted by using chemicals. Lifting, preserving and matching fingerprints requires forensic expertise. You can contact CSI for this service.
