• As technology continues to progress and
provide further degree of convenience to
our life, the world of criminal justice is also
informed by the by-products of this new
and exciting era.
• The rapid availability of new technology in
the world of crime has not only provided
enforcement officials with a greater array of
tools and new methods to aid them in
present of criminal justice.
COMPARISION OF TECHNOLOGY FROM PAST
In the past 4 decades when the
technology was not so advanced
the trackers were called to collect
the footprints and specially
trained dogs were used against
criminals which was a long
period to investigate and also
not so reliable.
The CCTV and satellites
(GPS SYSTEM) replaced the
trained dogs and trackers
in the prevention of crime
which is more reliable and
expose criminals clearly
and quickly to investigate.
In the past the only
weapons were like
arrows, shields and
swords which were
being used in the
prevention of crime by
In the pas there were no
metal detectors and
biometric system that
can be used in
prevention of crime.
Now in the era of modern
technology we have latest
weapons like automatic
machine guns, snipers etc.
which can fire many rounds
in a very short time span.
Now when the technology
has revolutionized the
world we have metal
detectors and biometric
verification system that has
helped the law
The recovery of fingerprints from a crime scene is
an important method of forensic science.
IN CRIME PREVENTION it comes with so many
benefits that traditional security system cannot
The first was the realization that 7 out of the 19
hijackers in the September 11 attack were known to
The introduction of DNA analysis was perhaps the
greatest advancement in terms of analyzing
DNA has been a powerful tool for crime solving.
An iris scan takes a detailed image of the ridges in the colored
part of the eye, usually through infrared photography.
These genetically determined ridges
are complex and unique.
The IRIS scanning technology is -
• Detailed and accurate
• More sanitary
• Not going to change from wear
• Fast to scan and quick to
Facial recognition is the process of identifying or
verifying the identity of a person using their face.
It captures, analyzes, and compares patterns
based on the person's facial details.
In the case of facial biometrics, a 2D or 3D
sensor "captures" a face.
Facial biometrics continues to be the preferred
That's because it's easy to deploy and
implement. There is no physical interaction with
Moreover, face detection and face match
processes for verification/identification are
It is now possible to use body odor as a biometric identifier to nab a culprit.
'Nose-witnesses' could soon help to identify unseen criminals.
An international team of researchers has
found that humans are able to remember a
particular body odor following a stressful
event to pick out the criminal in a line-up.
Body odor identification has largely been a
task left up to sniffer dogs due to the
assumption that humans have an inferior
sense of smell.
Crime prevention and reduction is a top priority for many
stakeholders including policymakers, police services and
In recent years, closed-circuit television (CCTV) surveillance
has emerged as a popular crime prevention measure
It is estimated that 49% of police departments in the United States use
CCTV, with usage increasing to 87% for agencies serving jurisdictions with
populations of 250,000 or more.
The prevalence of surveillance cameras in public places has led to a normalization of this
technology, allowing it to exist with little scrutiny from the public and media.
The aim of this systematic review is to present an updated analysis of the crime
prevention effects of CCTV.
They helps to create—
Create awareness among people
about the crime.
Law enforcement agencies can use
all social media in mass media tools
e.g. TV channels to organize and
promote crime prevention activities
and events e.g. activities includes
celebrate safe communities, national
night outs, loyal community affairs
THE ROLE OF GLOBAL
(GPS) IN POLICING
AND CRIME PREVENTION.
WHAT IS GPS?
The Global Positioning System (GPS) is a
navigation system using satellites, a receiver and
algorithms to synchronize location, velocity and
time data for air, sea and land travel.
GPS is made up of three different components,
segments, that work together to provide location
The three segments of GPS are:
•Space (Satellites) — The satellites circling the Earth,
transmitting signals to users on geographical position and
time of day.
•Ground control — The Control Segment is made up of
Earth-based monitor stations, master control stations and
•User equipment — GPS receivers and transmitters
including items like watches, smartphones and telematic
GPS was originally developed by the military to
aid in navigation. GPS as a way to enhance
customer service to track inventory and enhance
Global Positioning System applications
generally fall into 5 major categories:
• Location – determining a position
• Navigation – getting from one location to another
• Tracking – monitoring object or personal
• Mapping – creating maps of the world
• Timing – bringing precise timing to the world
HIDDEN WEAPON TECHNOLOGY
Mobile technology has become a powerful
Smartphones and cell phones have become a regular part of
criminal investigations because they are now owned by most
people and provide information about a person’s
whereabouts and a person’s contacts, says Adam Pincus,
a Legal instructor at South University, Online Programs. This
helps to jumpstart a criminal investigation
Every time someone uses a cell phone, a signal is sent out
that pinpoints where the user is. Cell towers and the GPS
features in some smartphones track where a phone is at any
“There is nothing either good or bad but thinking
made it so.”~ WILLIAM SHAKESPEARE
Though technology is also used for crimes but there is
no way one can ignore and resist the adoption of new
technologies any longer since recent developments in
information technology have changed the attitudes
and perceptions of police forces as well as criminals.
