Forensics
FORENSICS
Forensics, by and large, is the application of science to the legal process. It is an emerging research domain in India. There are many different types of forensic sciences baring their vital presence possibly in every field of human endeavor. Of these, let us now discuss about the computational, cyber and the DNA forensics.
COMPUTATIONAL FORENSICS:
The development of computational methods or mathematical and software techniques to solve forensic issues is called computational forensics. These methods analyze the evidence beyond human cognitive ability. They scrutinize a large volume of data, which is at any case impossible for a human mind to figure out. In spite of this, we can’t say that these techniques alone would serve our purpose because computational forensics is a field which needs huge collaboration between recognition and reasoning abilities of humans combined with comprehension and analytic abilities of the tool or a machine, which is most of the times, a computer.
Computational forensics aids us to model the uncertain. At the crime scenes, we usually get incomplete or broken evidences. These evidences are later on modeled by the computational forensic tool which gives us first clues from its largest biometric database (fingerprints, criminal histories, mug-shots, scar and tattoo, physical characteristics like height, weight, hair and eye color and aliases), which is a collection of significant information regarding the criminals, their criminal history and the nature of crimes committed. It gives possible hints and suggests possible matches of who the suspect is.
Computational forensics is not as easy as it seems. It is an intrinsic process whose central themes are accuracy and precision. For example, during finger – print analysis, as finger – prints are invisible to the naked eye, a computational forensic scientist lifts evidences carefully using either powder or ultraviolet illumination, avoiding the possibility of misinterpretation
