What is Facial Recognition? 

Facial Recognition is an identity verification technology that identifies or verifies a person by analysing and comparing patterns based on their facial features. This technology incorporates algorithms and machine learning (ML) to map facial landmarks, including the distance between the eyes, the shape of one’s cheekbones, and the contour of the lips, to create a unique digital template of an individual's face. These templates are then stored in databases and used to match against live images or video feeds to confirm identity. 

Facial Recognition systems can be deployed through various devices, including cameras, smartphones, and security systems, making it a versatile tool for numerous applications. The process involves capturing a facial image, extracting its unique features, and comparing it to a pre-existing database to find a match. The technology has advanced significantly, leveraging artificial intelligence (AI) and deep learning to improve accuracy and speed.
 

Why is Facial Recognition Important? 

Facial Recognition has become popular for its ability to enhance security measures. Companies use it to secure restricted areas, such as laboratories or rooms with valuable equipment, protecting assets and data from potential theft. 

In sectors like banking, government, and law enforcement, Facial Recognition is utilised for surveillance, border control, and crime prevention, aiding in the identification and apprehension of individuals involved in illicit activities. 

In healthcare, face detection is crucial for accurately identifying patients and accessing their medical records instantly. This capability allows healthcare providers to deliver personalised care and streamline administrative tasks. 

Additionally, Facial Recognition systems can assist in diagnosing certain medical conditions by analysing facial cues and expressions, potentially enabling earlier detection and treatment. 

How is Facial Recognition Used? 

Facial Recognition technology is employed in diverse fields, offering a range of applications that enhance security, convenience, and personalisation. Some of the common uses include: 

a) Finding Missing People: In law enforcement, Facial Recognition systems assist in locating missing individuals. Paired with street surveillance or traffic cameras, these systems can identify a single face in large crowds. The International Network of Associations of Disappeared Persons utilises volunteers equipped with Facial Recognition software on their smartphones to search for missing persons. 

b) Organising Photos by Face: Modern smartphones from Google and Apple can automatically sort photos in a user’s library by Facial Recognition. Google Photos offers a face grouping feature, while Apple’s Photos app includes a People & Pets feature for this purpose. 

c) Access to Transportation: The Transportation Security Administration (TSA) employs Facial Recognition to match travellers' images with their identification documents at airports, enhancing security and efficiency. 

d) Access to Personal Devices: Many Apple devices use the Face ID feature for Facial Recognition to unlock smartphones, allowing users to log in without a PIN or password. Apple claims there's less than a one-in-a-million chance of a random person unlocking another's iPhone with Face ID. 

e) Biometric Verification for Online Applications: Facial Recognition is used by various online platforms for user identification. For instance, DoorDash requires drivers to verify their identity with a selfie before delivering food. 

f) Medical Treatment: Facial Recognition aids in early illness detection. Applications like Face2Gene help doctors diagnose genetic disorders by using AI and deep learning to match facial features associated with these conditions. 

g) Filing Taxes: The IRS has previously used Facial Recognition to authenticate taxpayers' online accounts. However, they moved away from third-party Facial Recognition software due to privacy concerns. 

h) Keyless Guest Room Entry at Hotels: Facial Recognition is gaining popularity in the hotel industry for automated check-ins. The Vinpearl Nha Trang hotel chain uses Facial Recognition-powered check-in systems for a seamless guest experience. 

i) Targeted Marketing: Facial Recognition systems can personalise marketing by analysing consumers’ facial data. For example, Walgreens installed smart coolers with Facial Recognition cameras to detect shoppers' age and gender, displaying targeted ads based on this data. 

j) Social Media: Platforms like TikTok, Snapchat, and Instagram use Facial Recognition for face filters, allowing users to take augmented selfies. Additionally, these platforms can automatically suggest profiles to tag in photos. 

k) Accessibility: Facial Recognition enhances accessibility by describing photos to visually impaired users, including details about the people in the photos and their expressions. 

l) Contactless Building Entry: Facial Recognition provides contactless authentication for building entry, reducing touchpoints and ensuring adherence to health protocols, especially during the COVID-19 pandemic.
