CCTV Eyes Will Remain on Criminals, NCRB is Bringing Special Technology

The National Crime Records Bureau (NCRB) has started preparing for Automated Facial Recognition System (AFRS). With its help, people can be identified with photographs, videos in government databases. NCRB has sought tender from software and hardware-related companies related to facial recognition.

With the help of automated facial recognition system, criminals can be identified through photos. It will also help in finding people missing through photos and videos. However, the automated facial recognition system has also started questioning which and the number of agencies it will get access to. 

What is AFRS?

AFRS stands for Automatic facial recognition system, its a software which is used for identification of any person. In this technique first of all, identification of some nodal points on the face of any person is done. The nodal points are chosen in such a way that these points does not change with the age like distance between eyes, width of nose, depth below the eye, shape of bones and shape of jaw line. There are almost 80 nodal points in a face of any person. The record of these points are stored in the form of numbers or statistical codes. This process is completed in four phases:
  • Capture the digital image of any person in camera.
  • Checking of the image with different-different angles to check the different nodal points.
  • After it, the results are verified with the stored details in database.
  • If it matches with existing data then identification is completed. 
The algorithm that is used in this process is known as deep learning algorithm. 3D-technique is also used in AFRS system to identify accurately. With the help of 3D technique even in low light or in dark, identification is successful.

How it will be used?

Automatic Facial Recognition (AFRS) will be an internet connected system, which will be controlled from the data center of NCRB in New Delhi. It will also be accessed in all the police stations. For this, the Crime and Criminal Tracking Network and System (CCTNS) will be used. Blacklisted people will be able to identify their photo in the list of people and send an alert when the culprit is under CCTV. This system will also be able to upload photos in bulk. This system is able to match criminal photos through a passport, fingerprint sensor or any other identity in the database.

There are also questions about the misuse of facial recognition. Recently the use of facial recognition has been banned by police and security agencies in San Francisco City of San Francisco. There also questions about the security and accessibility of this database in India. Till now there is no privacy laws designed.

Other Options for Identification

  1. UID: uses Iris Scan  and fingerprints
  2. DNA Profiling: By making DNA data  bank
  3. Vein Pattern Scanning
  4. Identification of Body Odour: Using Chemical Pattern of body odour
  5. Heart Beat Detection
  6. Brain Wave Scan
