  1. 1. ROLE OF TECHNOLOGY IN CRIME PREVENTION
  2. 2. INTRODUCTION • 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.
  3. 3. 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.
  4. 4. In the past the only weapons were like arrows, shields and swords which were being used in the prevention of crime by law enforcement agencies. 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 enforcement agencies.

  6. 6.  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 offers.  The first was the realization that 7 out of the 19 hijackers in the September 11 attack were known to the authorities.
  7. 7.  The introduction of DNA analysis was perhaps the greatest advancement in terms of analyzing evidence.  DNA has been a powerful tool for crime solving.
  8. 8. IRIS  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 to tear. • Fast to scan and quick to retrieve.
  9. 9.  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 biometric benchmark.  That's because it's easy to deploy and implement. There is no physical interaction with the end-user.  Moreover, face detection and face match processes for verification/identification are speedy.
  10. 10.  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.
  11. 11.  Crime prevention and reduction is a top priority for many stakeholders including policymakers, police services and older adults.  In recent years, closed-circuit television (CCTV) surveillance has emerged as a popular crime prevention measure worldwide.  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.
  12. 12. SOCIAL MEDIAANDMASS MEDIA 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 etc.
  13. 13. THE ROLE OF GLOBAL POSITIONAL SYSTEMS (GPS) IN POLICING AND CRIME PREVENTION.
  14. 14. 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 information.  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 ground antenna. •User equipment — GPS receivers and transmitters including items like watches, smartphones and telematic devices.
  15. 15.  GPS was originally developed by the military to aid in navigation. GPS as a way to enhance customer service to track inventory and enhance security.  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 movement • Mapping – creating maps of the world • Timing – bringing precise timing to the world
  16. 16.  MOBILE TECHNOLOGY  HIDDEN WEAPON TECHNOLOGY
  17. 17.  Mobile technology has become a powerful crime-fighting tool.  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 moment.
  18. 18. HIDDEN WEAPON TECHNOLOGY
  19. 19. CONCLUSION  “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.
