Forensic STR profiling based smart barcode, a highly efficient and cost effective human identification system

Abstract

In forensic science, the human identification is the major goal in criminal cases and in paternity dispute, based on DNA profiling of individual. Analysis of short tandem repeat (STRs) markers used as a reliable technique for this purpose. In this study the main objective was to develop a human identification based on DNA fingerprinting using Human Identification Barcode System (HIBS). HIBS may be used to provide a unique molecular signature of human in the form of a barcode. DNA was isolated from blood by using PCR technique to detect bands to design human barcode using self-designed system. HIBS is a web based application that can be accessed via www.hibs.com.pk. HIBS can be accessed with internet access and may be introduced on security checkpoints to identify an individual based on his own DNA instead of conventional procedures of identification. The barcode generated through DNA fingerprinting will be stored in a HIBS, and may also be a part of CNIC. It may be successfully used against suicide bombers, target killers, etc., as even a single blood spot, a few skin cells, root of the hair etc., to identify such culprits. It may also be effectively used to relieve the individuals with false accusations.
