Facial recognition has become a cause for concern in western democracies. The European Commission is considering imposing a five-year moratorium on the use of facial recognition technologies in the European Union (EU).In the United States (US), municipalities have passed, or are considering passing prohibitions, India, however, is rushing to adopt public facial recognition.Facial recognition systems have been active at several major Indian airports, including the Delhi airport.These systems at airports have been installed under the DigiYatra initiative.Telangana’s election commission piloted a facial recognition app in its civic elections on January 22, and claimed that it could address the issue of voter impersonation. Facial recognition is a biometric technology that uses distinctive features on the face to identify and distinguish an individual. From the first cameras that could recognise faces in the mid-1960s up to now, facial recognition has evolved in many ways like from looking at 3D contours of a face to recognising skin patterns. With machine learning, the technology has become capable of sorting out types of faces.

Facial Recognition Technology(FRT) is a biometric technology for identifying a person by analysing the characteristics of a person’s face images taken with a digital camera.
Working: The mathematical algorithms of FRT follow following stages of image processing:

• Capture: The first step is to capture the image by using cameras or by scanning existing images.
• Extraction: Unique facial data is then extracted from the sample.
• Comparison: The data is then compared with the database.
• Matching: The software then decides whether the sample matches any picture in the database or not.

Application and benefits: It greatly improves security measures.It is already being used for examination, investigation,and monitoring by Governments all over the world to identify potential and current threats.There is even a progressive adaptation of FRT in medical applications.

Privacy Concerns: FRT can be used to unearth other personal data associated with an individual.

In this video we get to know the overall impact and challenges in dealing with this technology in New Global order.
