Overview Of Technological Advancement In Criminal Investigation System
Explain technological advancement in criminal investigation system
Technology is present everywhere in the life and it became part of our life. Jobs related to criminal justice today involves GPS, advance camera, robots etc. all these technologies improve investigation system and made it easier. Some details about technologies are given below.
Database & Information Exchange
The computer database system is important technology for criminal investigation system. There are many database systems that deal with profiling of criminal. They can also deal with DNA testing, hot-spot analysis etc. these database can be transferred much faster between states and countries. There are advance matching technologies are also available. Also, there are many biometric tools that analyze fingerprints with more detail.
Digital video recording
The cameras that use this technologies are in the practice already. These technologies are very practical and affordable. The video captured by this digital camera serve as important proof in investigation system. These cameras are light weighted and don’t require more space and allow police officer to carry with uniform or their car.
3D imaging of crime scene
This technology look like a part of science fiction. These devices take 3D scan of crime scene, switching a lot of photos. This way crime scene can by shown to detail. By these method crime scene can be visualize and some missing proof can be found out. This technology makes investigation system easier and fast compared to old system.
Crime pattern analysis system
The CPAC provides digital maps which display all or specific crime that occur in a specific area. This system analyze the data and prepare colored graphical map to show density of specific crime. It also have feature, using statics it extrapolates total crime figure for a many days and also predict where crime will occur tomorrow.
Regional crime analysis project
This project was started by university of Virginia along with their local police department. ReCAP uses a GIS with machine learning and statistical analysis to examine a corporate database. This systems effectiveness is still good.
Ottawa Police Service
The Ottawa police service, Canada began development of an expert system to investigate crime.
Eight initial functionality goals were set:
- Provide support for recording and gathering case data
- Generate suspect characteristics from case
- Provide the easy access to the investigators
- Identify the motive of suspects and cleared the cases
- Generate the list of possible suspects
- Identify patterns in the area
- Generate reports in appropriate format
- Provide a graphic display capability
This system is used by many Canadian police departments and its marketed by a private software company.
Investigation Management Software
Case management software is a web based solution to manage investigations. Dashboard reporting and custom report writing ability gives you data on case status and crime trends. These software can be used for investigation of fraud, employee relationship, privacy, security and health and safety. It maintain complete case histories with instant access to all related information. Ex. i-sight, logikcull, formdocs etc.
Thus many new technologies help crime investigation system. Some technologies are still under development like drones, robots etc. this technologies also helps criminal to do crime effectively so investigation systems have to be one step ahead.
