Facial Recognition ToolsThe criminal defense departments are relying upon facial recognition technologies to get hold of serial killers

Facial recognition can help verify a person's identity. A facial recognition system uses biometrics to map facial features from a photograph or video. Face recognition technology capable of matching faces from the digital image, videos, or any audiovisual element of her/his face. Facial recognition helps law enforcement find missing children, fight human trafficking, find dangerous criminals and bring sexual predators to justice. Facial recognition technology has a whole range of applications across a wide array of market sectors, from retail and business to travel and education.

Here mentioned some facial recognition cases:

Narcotics Trafficking Investigation: The State-wide Network of Agency Photos Unit in Michigan received a request from an out-of-state law enforcement agency to help identify an unknown subject believed to be from Michigan who was part of a drug trafficking ring in their state. A facial recognition search was conducted, and a viable candidate returned. The investigative lead was provided to investigators who later confirmed this was the subject they were attempting to identify. This subject was involved in numerous drug trafficking investigations in Michigan and West Virginia.

Surveillance sunglasses: Chinese police have started to use sunglasses equipped with facial recognition technology to identify suspected criminals. The wirelessly-enabled glasses are linked to a database of suspects, allowing police officers to scan crowds and identify criminals much faster than they could do on their own. This technology has already helped police catch several suspects in Zhengzhou. The system itself works by this technology to compare photos taken by patrolling police officers to a blacklist of known offenders.

Finding an Alleged Rapist: In New York City in 2019, a man raped and killed a woman. Investigators used facial recognition technology to compare images from surveillance video at a nearby food store with a mugshot database. Along with additional investigative work, this allowed them to identify a suspect and make an arrest within 24 hours.

Facial recognition in airport boarding: In 2009, the adenosine Triphosphate group introduced PARAFE fingerprint recognition technology to speed up the process. But, only 4% of people could use it. Later in 2017, the airport authorities decided to upgrade PARAFE with facial recognition systems provided by Gemalto. Almost half of the travelers have passports compatible with facial biometrics. Since 2018, many more airlines have started to use this technology. In the US alone, more than 15 airports have set up face matching systems to help board passengers faster and more safely.

Finding criminals: This technology improves response times and ultimately helps prevent or mitigate harm from terror attacks and save lives. New York City Police Department detectives used facial recognition technology to identify a man who sparked terror by leaving a pair of rice cookers in the Fulton Street subway station

Saving a sex trafficking: This technology helps investigators find underage sex trafficking victims in online ads.  Spotlight has reportedly been used in 40,000 cases in North America, helping rescue 15,000 children and identify 17,000 traffickers.

Helps in missing persons: In India, this technology has helped police find 3,000 missing children in only four days. In March 2018, local and federal law enforcement officers were trying to recover a child missing for four months. Law enforcement officers initiated surveillance on the subject which revealed the missing child hiding in the rear seat of the subject’s vehicle.
