A human face is one of the most important biometric features and creating a reliable computer system for Facial Recognition is a complex undertaking.
What Is Facial Recognition?
Facial recognition is a type of biometric security that uses a person’s face to verify their identification. The technology gathers a set of specific biometric information about each individual related to their face and facial expression. It is capable of recognizing people through photos, videos or any audiovisual element.
The identification typically functions like a face scanner and is used to access a program, system or service. The biometric identification technique uses the bodily measurements of the subject, like the face and head to confirm the subject’s identity using their facial biometric pattern and data.
Facial recognition technology can also recognize voices, fingerprints and the retina or iris of the eye. It is mostly used for security and law enforcement. Recognition and authentication are the two basic purposes of Facial Recognition Software.
Face recognition technology (FRT) confirms a specific person’s existence in digital capture.
Face authentication software (FAS) gives a specific person access to anything physically or digitally.
Face authentication indicates that the user has provided permission for the collection and storage of their faceprint information. They also know what the data is used for and have the option to opt out of the system whenever they choose.
As opposed to traditional physical credential systems, one of the major advantages of employing face authentication for physical access control is that it offers a higher level of security. It also improves user experience by relieving users of the burden of creating and updating strong, unique passwords.
How Does Facial Recognition Software Work?
FaceID, the authentication feature used by iPhones, is a popular way for many people to become familiar with face recognition technology. Facial recognition usually identifies and recognizes one person as the single owner of the device, limiting access to others, rather than relying on a large database of images to determine an individual’s identification.
Facial recognition technology goes beyond phone unlocking and works by comparing the faces of persons passing by special cameras to pictures of people on a watch list. Although facial technology systems can differ, they usually function as follows:
1. Face detection
The camera can recognize faces whether alone or among a group of people. The subject can be shown facing directly ahead or in profile.
2. Face evaluation
In the next step, the face is photographed and examined. The majority of facial recognition technology uses 2D rather than 3D photographs as it is easier to match a 2D image with existing data or with public photos. The software reads the features of the subject’s face.
Some of the key features of the face that are all important considerations include the distance between the eyes, the depth of the eye sockets, the space between the forehead and chin, the form of the cheekbones and the shape of the lips, ears and chin. The objective is to recognize the distinctive facial features that make the subject’s face unique.
3. Processing the image into data
Based on the subject’s facial traits, the face capture procedure converts physical information (a face) into a collection of digital information (data). The analysis of the face is converted to a mathematical formula which is called a faceprint. Every person has a faceprint, just like every thumbprint is different.
4. Locating a match
In the final step, the faceprint is matched to a database of recognized faces. A decision is made if the subject’s faceprint matches a picture in a facial recognition database. Facial recognition is regarded as the most realistic biometric assessment. According to figures, facial recognition technology regularly interacts with more than half of the world’s population.
Furthermore, advances in machine learning (ML) and artificial intelligence (AI) allow reference samples to be updated continuously in real-time. This has the advantage of making this kind of system easier to operate over time, in addition to enhancing accuracy.
Facial Recognition Software in Border Control Systems
The testing and application of facial recognition technology by Customs and Border Protection (CBP) at land, sea and airports around the nation are progressing. As an organization, CBP is largely in charge of managing and controlling borders. It is rapidly being implemented in several ports and border crossings to boost security and efficiency.
The CBP uses this technology to scan travelers at seaports, airports and border crossings. Other responsibilities include dealing with issues relating to customs and immigration and necessary identity checks for visitors entering and leaving the United States.
The International Civil Aviation Organization (ICAO) selected three biometric modalities for inclusion in machine-readable travel documents, with facial recognition being one of them. In the age of digitization, images are not only printed on passports but are also kept as files in the chips of electronic passports.
Facial recognition can help automate border crossing. Here, the computer matches the facial image read from the electronic passport with the facial image captured by a camera at the border crossing point. Similar to other biometric systems, the performance of the system is greatly influenced by the quality of the reference biometric data.
The specification includes prerequisites for posture, emotion, backgrounds, shadows and eyewear. Some of the benefits of using facial recognition for border control are:
- It’s practical and cost-effective to utilize facial recognition technology for traveler identification since it allows travelers to scan their passports. This will boost convenience and cut down on needless processing time.
- It provides high degrees of human identification accuracy thus enhancing border security.
- The danger of human error in the processing of immigration is eliminated by facial recognition biometrics.
- It helps the border patrol agents automate passport inspections, freeing up immigration personnel to focus on more crucial tasks like removing terrorist risks at the border.
- It is frequently preferred over other biometric identifying methods like fingerprinting due to its passive nature.
- It is used when providing identity documents to prevent identity fraud and identity theft.
