Abstract - The work aims to find improved and extensive
ways to Boost, Broaden and Vest Forensic Science techniques
in all its branches by using current science & technologies and
also employing the new, latest and upcoming technologies,
such as Artificial Intelligence (AI). The paper converses the
present-day and probable forthcoming applications of AI in
Forensic Science. For example, AI can be employed in Blood
Pattern Recognition & Analysis, Crime Scene Reconstruction,
Digital Forensics, Image-processing and of course Satellite
Monitoring. AI has a vast variety of applications, with
preliminary being the investigation of crime scene till the
ultimate judgment is being delivered by the court of law, AI
show high potential in precision of result.
Key Words: Artificial Intelligence, Artificial Neural
Network, Forensics, Data Analysis and pattern
recognition.
1. INTRODUCTION
Forensic Science is the application of scientific principles,
methods and techniques for the purposes of justice. It
involves the use of effective scientific techniques and
methods to investigate the crime and serve justice to
involved parties. The word Forensic science has its roots
embedded in ancient Roman times, where when an
individual was charged with a crime, he/she was made to
present the case before a group of public individuals in the
forensic, meaning forum. The forensic was accountable for
delivering the final judgment, after hearing the case from
victim and from suspect.
1.1 Artificial Intelligence
Artificial Intelligence (AI) sometimes called as machine
intelligence, is machine’s ability to show intelligence which is
similar to the intelligence shown by humans and animals. Top
Artificial Intelligence textbooks define this field as the study
of "intelligent agents": any machine that senses it’s
environment to perceive information and then take action
according to the received data to maximize its chances of
successfully achieving its goals. In the language of ordinary or
familiar conversation, the term "Artificial Intelligence" is
often used to describe the machines which imitate the
"cognitive" functions of humans i.e. the intelligence functions
that the human mind performs, including but not limited to
"learning" and "problem-solving".[11]
1.2 Artificial Neural Networks
Artificial Neural Networks (ANN) are computing systems
like biological neural networks that form up animal brains.
These systems are not programmed to perform specific
tasks, that would take so many lines of code and won’t even
work for all the tasks.[10] ANN perform tasks by learning
from the given examples. For example, they may learn to
recognize photos that have dogs in them in image
recognition by examining example photos that have been
labeled as "dog" or "no dog" and using the findings to
recognize dogs in other pictures. For example, they do so
without any previous awareness about dogs, photos that
have dog-like features, four legs and body form. Instead, they
transfer pixel by pixel across the image pixel and produce
identifying characteristics from the examples given and
processed.
Simultaneously, in Forensic Science there are six principles
which are to be considered: First, Law of Individuality
Second, Locard’s Principle of Exchange, third, Principle of
Comparison, fourth, Principle of Analysis, Fifth, Principle of
Probability and lastly, Law of Progressive Change[13]. The
most basic principles of forensic science are the Locard’s
principle of exchange which states that “when two entities
come in contact with each other they leave a trace on each
other”. This principle is fundamentally responsible for the
basis of Forensic Science & Investigation, and also for AI in
the sense that even a pattern will be enough to identify the
suspect and will help us to perform our proceedings from
Crime Scene to Courtrooms.
Artificial Neural Network Applications in Forensic Science
ANN and Artificial Intelligence will be of great help, if
implemented properly in Forensic Science Fields. Some of its
applications will be able to define its vast extent in Forensic
World.
2. DEFINITIONS
2.1 Artificial Intelligence
It is not easy to describe Artificial Intelligence, there is no
well-established definition of Artificial Intelligence. Most of
the concepts that exist tend to describe Artificial Intelligence
in terms of "creating a computer process that acts
intelligently" (but what is intelligence?) or "creating a
computer process that can imitate human actions" (do people
always act intelligently, what happens if a machine usually
