Facial recognition software use, advantages, disadvantages & How does facial recognition work?
Face recognition system identifies or confirms a person’s identity using his face, It works by identifying and measuring facial features in an image, It can identify human faces in images or videos, It is used in grocery stores, tagging friends on social media, or logging into our smartphones.
What is facial recognition?
The facial recognition system can match the human face from a digital image or a video frame against a database of faces, It can authenticate users through ID verification services, and it can pinpoint and measure facial features from a given image, Facial recognition systems are used in advanced human–computer interaction, video surveillance and automatic indexing of images.
Advantages of face recognition systems
Facial recognition system is a quick and efficient verification system, It is faster and more convenient compared to other biometric technologies like fingerprints or retina scans, It supports multifactor authentication for additional security verification, There are fewer touchpoints in facial recognition compared to entering passwords or PINs.
Facial recognition is a very accurate way to identify individuals than simply using a mobile number, email address, mailing address, or IP address, Face recognition system is compatible and integrates easily with most security software, and smartphones with front-facing cameras have built-in support for facial recognition algorithms or software code.
Facial recognition system is used to unlock devices, It can be used at airports, It can help us to improve our overall safety levels, It may be a good measure to avoid the spread of diseases, It helps to protect essential infrastructure, It can help to make processes more efficient, It helps to identify fake passports, It can prevent all kinds of fraud, but it is harder to hide for criminals, Machine learning & AI will help to improve and expand facial recognition.
Face recognition can be performed without a person even knowing, it is easy to use in any case, It is more user-friendly, It is convenient, It can help users to improve our overall safety levels, It is an inexpensive technique of identification, and it has social acceptability.
Facial recognition system may be a good measure to avoid the spread of diseases, It helps find missing people, It protects businesses against theft, It improves medical treatment, It strengthens security measures, and it makes shopping more efficient.
Disadvantages of face recognition systems
Facial recognition can take away freedom and fun from people, It can be misused by governments, It can lead to higher unemployment rates, Sensitive data may get stolen by hackers, there are rules and regulations against facial recognition in some regions, Storage of data can be problematic, and excessive reliance on facial recognition can be dangerous.
Face recognition systems can’t tell the difference between identical twins, It may be expensive, High false match range, and privacy concerns related to facial recognition, there is a problem with false rejection when people change their hairstyles, Lack of regulations in the AI in face recognition systems, Potential for primary abuse, and the general public may not accept this technology.
Facial recognition reduces the number of touchpoints, It improves photo organization, It violates personal rights, It has data vulnerabilities, Its misuse causes fraud and other crimes, Errors can implicate innocent people, and this technology can be manipulated.
Applications of face recognition systems
The companies use facial recognition to uniquely identify users creating a new account on an online platform, facial recognition is used to verify the actual person’s identity. It is used to gain access to patient records, It can streamline the patient registration process in the healthcare facility and autodetect pain and emotion in patients.
Companies can use facial recognition technology instead of passwords to strengthen cybersecurity measures, It is challenging to gain unauthorized access to facial recognition systems, as nothing can be changed about your face, Face recognition software is a convenient and highly accurate security tool for unlocking smartphones and other personal devices.
Biometric data such as passports at airports allows travellers to skip long lines and walk through an automated terminal to reach their gate faster, Face recognition system in the form of e-Passports can reduce wait times and improves security.
Individuals authenticate transactions by simply looking at their phone or computer instead of using one-time passwords or two-step verification, Facial recognition system is safer because there are no passwords for hackers to compromise, and some ATM cash withdrawals and checkout registers use facial recognition for approving payments.
How does facial recognition work?
The facial recognition system works in three steps: detection, analysis, and recognition, Detection is the process of finding the face in an image, Enabled by computer vision, facial recognition identifies individual faces from the image containing one or many people’s faces, It can detect facial data in both front and side face profiles.
Computer vision automates extraction, analysis, classification, and understanding of useful information from image data, The image data takes many forms, such as single images, video sequences, views from multiple cameras, and three-dimensional data.
Facial recognition analyzes the image of the face, It maps and reads face geometry and facial expressions, It identifies facial landmarks that are key to distinguishing a face from other objects, It looks for the distance between the eyes, distance from the forehead to the chin, the distance between the nose and mouth, and depth of the eye sockets.
Facial recognition converts the face recognition data into a string of numbers or points called a faceprint, Each person has a unique faceprint, similar to a fingerprint, Facial recognition system identifies the person by comparing the faces in two or more images and assessing the likelihood of a face match, it can verify that the face shown in a selfie taken by a mobile camera matches the face in an image of a government-issued ID like a driver’s license or passport.
Is facial recognition accurate?
Facial recognition algorithms have near-perfect accuracy in ideal conditions, There is a higher success rate in controlled settings but generally a lower performance rate in the real world, It is difficult to accurately predict the success rate of this technology, as no single measure provides a complete picture.
