DNA genetic fingerprinting for

forensic science DNA profiling (also called DNA testing, DNA

typing, or genetic fingerprinting) is a

technique employed by forensic scientists toassist in the identification of individuals by

their respective DNA profiles.

CODIS

Combined DNA Index System(CODIS) is the generic term used todescribe the FBIs program of supportfor criminal justice DNA databases aswell as the software used to runthese databases. The National DNAIndex System or NDIS is consideredone part of CODIS, the national level,containing the DNA profilescontributed by federal, state, andlocal participating forensiclaboratories.It was developed in1980s

AUTOMATED BALLISTIC

IDENTIFICATION SYSTEM Automated Ballistic Identification Systems (ABIS) are

specialized computer hardware/software combinationsdesigned to capture, store and rapidly compare digital imagesof bullets and cartridge casings.

ABIS have four key components: The Ballistic Scanner, which captures the images of the bullets

and cartridges

The Signature Extraction Unit, which uses amathematical algorithm to extract unique signatures from the

images Data Storage Unit, which serves as the main storage,

The Correlation Server, which handles the actual comparison ofimages.
