Unlock the Future with Cutting-Edge Face Recognition Online

Wed Mar 29 2023

The use of face recognition online technology has grown significantly in recent years, with new devices and applications being developed and released every day. This fascinating and significant growth area, once the stuff of science fiction, is rapidly becoming a reality. The COVID-19 pandemic has also made it more urgent for many sectors to seize the opportunities that this technology offers. We can expect facial recognition to become more prevalent in all aspects of our daily lives, from buying a hamburger to boarding an airplane. Of course, many of us have become accustomed to using face recognition in our daily interactions. This technology is a common feature of modern smartphones, allowing users to unlock their devices quickly and without physical interaction. This article discusses how businesses are using facial recognition technologies.

What is Face Recognition?

what is face recognition

Face recognition is a technique for identifying or verifying the identity of a person based on his/her face. This system can recognize human faces in images or videos, judge whether a face appears in two images of the same person, or search for a face among many existing images. Facial recognition is a technique used by biometric security systems to more reliably identify users during the registration or login process. Facial analysis technology is also widely used in mobile and personal devices to ensure device security.

How does Face Recognition work?

In addition to unlocking phones, face recognition uses sophisticated cameras to compare the faces of passersby with images of people on a pre-defined list. The photos on the pre-defined lists can come from anywhere, including our social media accounts, and they can be of anyone, including those who aren't suspected of a crime. Although facial recognition systems can vary, they typically work as follows


Locating a face in a picture is the process of face recognition online. Computer vision makes face detection and identification from an image, including one or more people's faces, possible. Both front and side face profiles with facial data can be detected. Through computer vision, computers can now recognize individuals, locations, and objects in photos with accuracy comparable with or better than that of humans and at a considerably faster rate. Computer vision automates the extraction, analysis, classification, and understanding of useful information from image editing data using sophisticated artificial intelligence (AI) technology.


The face is then captured and evaluated in the next step. Most facial recognition technology uses 2D rather than 3D photos because matching a 2D image to existing data or public photos is faster. The computer analyzes the geometry of your face. The distance between your eyes, the depth of your eye sockets, the distance between your forehead and chin, the shape of your cheekbones, and the shape of your lips, ears, and chin are all important considerations. The goal is to identify the distinctive features that make your face unique.


Facial recognition can identify a person by comparing the faces in two or more photographs and determining the probability that two faces match. For example, it can confirm that the face in a selfie taken with a mobile device matches the face in an image of a government-issued ID, such as a driver's license or passport, and confirm that the face in the selfie does not match a face in a collection of previously photographed faces.

Advantages of Face Recognition Online

Sometimes we are asked what are the advantages of face recognition online. Facial recognition offers several benefits in the identity verification process for remote entry. The following are some advantages of this technology:

Increased security

Governments can use facial recognition technology to track down terrorists and other criminals. Home CCTV systems and personal electronics can both be secured using face recognition technology.

Improved accuracy

Using a mobile number, email address, mailing address, or IP address alone is less reliable than facial recognition when trying to identify someone. For instance, most exchange services, including those for stocks and cryptocurrencies, now rely on this system to safeguard clients' money.

Faster processing

Face recognition online is advantageous for businesses that utilize it because it simply requires a second to identify a face. Organizations require safe and efficient solutions in an era of sophisticated hacking tools and cyberattacks. Face recognition enables a quick and efficient verification process.

Easier integration

The majority of security software is consistent with and easily integrated with face recognition online technologies. For instance, smartphones with front-facing cameras already support face recognition algorithms or software code.

Disadvantages of Face Recognition Online

A cutting-edge technology called facial recognition online can potentially change our future. However, as with any invention, introducing this new technology into society has some dangers and implications. Some of the drawbacks or difficulties seem to be.


Some people are concerned that the widespread use of facial recognition technology, along with video cameras, artificial intelligence, and data analysis, raises the possibility of mass surveillance that would limit personal freedom. Governments can use this technology to track criminals, but they can also track ordinary people at any time.

Room for error

Facial recognition data can contain errors that could lead to false accusations against innocent people. For example, a slight adjustment in camera position or a change in appearance, such as a new hairstyle, can lead to inaccuracies. According to a Newsweek investigation, 28 members of the U.S. Congress were misidentified by Amazon's facial recognition software in 2018.

Invasion of privacy

The most divisive issue is one of ethics and privacy. Governments have been known to store images of some people without their permission. The European Commission announced in 2020 that it is considering banning facial recognition technology in public areas for up to five years, to give time to develop a legal framework to prevent privacy and ethical breaches.

Massive data storage

Machine Learning as a Service is the foundation of facial recognition software, and in order for it to "learn" and produce reliable results, it requires massive amounts of data. These massive data sets require robust data storage. Small and medium-sized businesses may not have the tools to store the necessary data.

Applications and Use Cases of Face Recognition Online

Use Cases of Face Recognition

AI face recognition technology is used for various purposes, including fighting pandemics, improving usability assessments, and helping to secure and monitor a work environment. The most common uses for facial recognition are listed below.


Traditional security measures focus on monitoring recorded or live video feeds and manually notifying designated personnel of suspicious activity. This process is expensive, time-consuming, and unreliable. Face recognition online technology can be integrated into security systems to improve security and surveillance across industries and reduce costs. It can identify any user in the system's database and individuals directly in front of a camera and generate notifications for precise human intervention. But face recognition online can do so much more! By aiding in identifying and preventing crime, this technology offers a wealth of benefits to law enforcement. It could improve the safety of people around the world.

Access Control

Organizations such as schools, churches, and businesses need to monitor attendance carefully. This may be to monitor compliance with attendance policies or for statistical purposes. Traditional methods are inefficient, slow, and prone to error. Traditional time and attendance systems require employees to clock in and out using their physical identities, personal information, and even biometrics. Facial recognition software has expedited this element of the process by ensuring that attendance is reliably recorded without requiring any special action on the part of students, teachers, or other supervisors. Integrating it with programs that collect attendance data and look for trends can take this a step further.


Facial recognition software can be used to identify diseases that cause observable physical changes. For example, the National Human Genome Institute uses facial recognition to identify DiGeorge syndrome. This groundbreaking technology diagnosed the condition 96% of the time. As the algorithms become more sophisticated, they will become an important diagnostic tool for many diseases.


Banking is another sector where face recognition online software is on the rise. Passwords, PINs, and other seemingly traditional security measures are no longer necessary as some banks integrate this technology into their mobile banking systems. Some ATMs use facial recognition software as an additional layer of security. This can help confirm that the person withdrawing money is the account holder and identify any possible background manipulation. Today's banks often use facial recognition for a variety of functions. Special customers can be identified and assisted as they enter a facility, known criminals can be closely monitored, and employees can move about the facility without scanning their key cards every few feet.

How is Face Recognition Different from Facial Detection?

Face detection vs face recognition

As you can see, Face Recognition and Face Detection differ in some pretty important ways, but they are inextricably linked. The most important distinction-and the one you should be aware of if you're not sure which to use-is that a system is considered capable of face recognition. Face recognition online, on the other hand, advances this by recognizing and identifying the observed face based on a match recorded in a database.

The Saiwa Face recognition service

Saiwa's online face recognition service is based on its face recognition algorithms. Users can experiment with two face detectors in two ways:

  • Recognition using the Dlib face detector.
  • Recognition using the MTCNN face detector.

The two methods differ in detecting stage. For more details about both saiwa face detection online algorithms, please refer to here. After detecting faces and face landmarks with the HOG SVM face detector, the faces are rotated, scaled, and sheared so that the face landmarks are close to the frontal model. Face coding is done after face detection and fractalization. All reference images of known reference faces and unknown input faces must be encoded similarly. Finally, an SVM algorithm classifier, previously trained on all reference faces, is used to find the reference face that matches the unknown input.
