pros and cons of facial recognition
Advantages of Facial Recognition
  • Convenience of life
Facial recognition  door access entry is touted as something that makes our lives easier.Where once we had to enter a password before we could use our cell phones, when we went to the airport and had to show our ID cards and passports to prove our information when we had various packages in our hands, now our facial information is enough to prove who we are.. Four train stations in Osaka have implemented facial recognition systems that allow people to pass by simply scanning their faces, without the need for a ticket or ID card. A transportation official noted that they will "emphasize the advantage that passengers with large luggage can simply show their faces to pass through the gate without having to look for a ticket.
While the internal process of biometric authentication is technical, from the user's point of view, it is simple and fast. It is faster to place your finger on the scanner and unlock your account in seconds than to enter a long password containing multiple special characters. IBesides that, the matter of forgetting password is one of the most common situations in our life. Is it possible for you to forget your biometrics?0%!
  • Ensure security
facial recognition time clock with temperature  helps ensure security. Face detection improves surveillance and helps track criminals and terrorists. Personal security is also enhanced because hackers don't have anything to steal or change, such as passwords.
Biometrics are said to provide a higher level of assurance that the person trying to access a service or conduct a transaction is genuine. Those who favor the use of biometrics point out that passwords, PINs and other personally identifiable information can be compromised by a data breach, allowing fraudsters to access accounts that use traditional authentication methods. In contrast, it is more difficult for someone other than you to provide your fingerprints on the spot. In law enforcement, proponents of facial recognition argue that it can make it easier for police to track down suspects.
Law enforcement agencies use the technology to spot criminals or find missing children or elderly people. In New York, an alleged rapist was arrested using facial recognition technology within 24 hours of an incident in which he threatened a woman with a knife to commit rape.Facial recognition systems can be set up at company entrances to help businesses detect crime when the police are not available..
Security predicts that 97 percent of travelers will be using it by 2023. Installing facial recognition solutions in public or hidden places can be effective in reducing the discipline of crime because people know that the police are monitoring them
In an era of cyber attacks and advanced hacking tools, companies need a technology that is both secure and fast. Considering that facial recognition is almost instantaneous, it can verify a person quickly and effectively. In addition, it is difficult to spoof this technology, so this is another benefit.
Thieves and other criminals will think twice before engaging in illegal activities because they know that the chances of being arrested are greatly increased if proper facial recognition technology is used.
Therefore, if facial recognition is implemented, the incentive to commit a crime is much lower because people know that the risk of arrest and conviction is also much higher.
  • Seamless integration
This is probably one of the biggest benefits for the company. Facial recognition technology is easy to integrate, which makes it a perfect choice. Having one facial recognition device can solve most solutions such as palm + face, fingerprint + face, card + face, health code + face. 100% win-win with one machine and multiple solutions
  • Recognition Automation
Previously, security personnel had to manually identify a person, which took too long and was not very accurate. In the past, recognition was done manually by a person; it was inefficient and often inaccurate. Face detection allows for an automated recognition process that saves time and improves accuracy But today, facial recognition is completely independent of the recognition process and not only takes only a few seconds, but is very accurate.
The use of 3D face recognition technology and infrared cameras has greatly improved the accuracy of face recognition and made it very difficult to recognize faces.
One of the advantages of facial recognition is that it can be used to unlock our electronic devices.
Although it is not yet widely used, it will become commonplace to unlock our smartphones or computers with a simple glance at the camera.
Imagine no longer having to remember your PIN code, just look at your screen.
  • Can be used in airports
Facial recognition is also a very important tool when it comes to controlling people at airports.
Often, large numbers of people must be supervised at the same time, and by using intelligent technology such as facial recognition, machines can do many of the tasks that would otherwise require a large number of employees.
As a result, facial recognition also allows us to work in a more convenient way because cameras and computers can do more unpleasant tasks.

  • Machine learning and artificial intelligence will help improve and extend facial recognition
In our current state of the world, we are very fortunate because machine learning and artificial intelligence can really make our lives easier in the future
These technologies will also help with facial recognition, as over time, cameras will be able to recognize people better through a self-learning process.
Therefore, facial recognition will also get better over time and can help us a lot in several aspects of our lives.
  • Facial recognition could be a good measure to avoid the spread of diseases
With facial recognition thermal scanner , we can also avoid the spread of diseases.
Facial recognition works only by looking at the camera and no longer requires us to physically touch the device.
As a result, the chances of catching the flu or other diseases can be reduced, which benefits not only ourselves, but also the economy as a whole, as GDP may increase as a result.
  • May help protect critical infrastructure
Facial recognition can also help us protect critical infrastructure from attacks.
For example, power plants and other critical equipment could be equipped with facial recognition technology, and the chances of criminals attacking such critical infrastructure and getting away with it would be much lower.
Power plants, financial institutions, telecommunication institutions, and other important buildings that need to be protected at all costs can be protected with facial recognition solutions.
  • Facial recognition helps improve process efficiency
Facial recognition is a technological, unemotional biometric technology, but it is the technology that makes our lives and work more fluid and efficient..
For example, if you are at an airport, you often have to wait a long time for your passport and other documents to be checked.
However, these processes can be greatly facilitated by the use of advanced facial recognition technology.
So, in the future, many processes may become more efficient thanks to facial recognition, which could save us a lot of time in the long run.
May help identify fake passports
If facial recognition technology becomes advanced enough in the future, it may also be able to detect fake passports.
Even in our current state of the world, there are people forging good quality passports, and many police and other officials looking at them won't even realize they're fake.
Thus, facial recognition could also help us solve the problem of fake passports, which is very common worldwide.
More difficult to hide for criminals
Another benefit of facial recognition technology is that once criminals are placed on a wanted list, they will be much harder to hide.
Even if they try to relocate to a remote country on our planet, sooner or later the cameras will capture their faces and if these photos are matched with international databases, the criminals are likely to be caught quickly and have nowhere to hide in the vicinity Thanks to this technology in the future
Fraud of all kinds could be prevented
Facial recognition may also help prevent many different types of fraud.
For example, if you will be able to make credit card payments using facial recognition technology, it may become more difficult for criminals to use your credit card information because they still don't have your face, so you may be able to prevent several types of fraud that will occur in the near future as a result of using facial recognition.
Help find missing persons and identify perpetrators
Law enforcement structures use facial information from facial systems to help us identify missing persons by comparing them with the database of reported missing persons.
They also use it to find missing children by combining facial recognition with aging software to predict what children will look like in a few years and find them even if they have been missing for years. When there is an unknown situation or person, the system sends an alert that is transmitted directly to the police system, and the police conduct real-time investigation and analysis based on surveillance

  • Protecting businesses from theft
temperature kiosk with facial recognition software can be an effective preventive measure against shoplifting. Supermarkets are now installing facial recognition surveillance, for one thing, if a theft is discovered information can be retrieved based on the surveillance, and the presence of facial recognition surveillance itself provides a certain deterrent
The software can also help identify and track thieves if the business is eventually burglarized. 
Enhanced security measures at banks and airports
  • Facial recognition can also help improve security at non-retail locations such as airports and banks. 
It has been a regular part of airport security screening for years. Similar to identifying criminals entering stores, the software helps identify criminals and potential threats to airlines and passengers.
U.S. Customs and Border Protection (CBP) has pledged to use facial recognition on 97 percent of international passengers by 2023. 
Another benefit is that it can perform border checks faster and more accurately than people.
Institutions like banks use the software in the same way to prevent fraud, identifying people previously charged with crimes and alerting banks so they know to pay special attention to that person's business at the bank. 
  • Making shopping more efficient
While identifying and locating missing persons and criminals are arguably the most important benefits of facial recognition, they go beyond security and extend to convenience as well. 
Supermarket checkout has slowly upgraded from the initial cash payment, card payment, mobile payment to facial recognition payment. By simply tying your facial information to your account, the ability to swipe your face for a bill is now possible
The use of this technology has increased during the pandemic to provide convenience and security purposes and to help manage smaller employee-to-customer ratios, but retailers also see a future where the technology will be used to identify and advertise in and out to loyalty club members and clock employees. 
  • Reducing the number of touch points
facial recognition clock in system  will consume a little less human resources than some biometric technologies such as fingerprint recognition.. It also does not require physical contact or direct human interaction. Instead, it uses artificial intelligence to make it an automatic and seamless process. 
It also limits touch points when unlocking doors and smartphones, withdrawing money from ATMs or performing any other task that would normally require a PIN, password or key. 
  • Improved photo organization
Facial recognition also allows you to tag photos in your cloud storage via Apple or Google.Your photo is made public, so others can easily find your information.. It also plays a role in suggesting Facebook tags. 
  • Improving healthcare
Genetic diseases are generally difficult to detect at first, and only become apparent at the onset of the disease, but one particularly surprising feature of facial recognition technology is that it can detect such diseases.

Facial recognition can bring many benefits to society, from preventing crime and improving security to reducing unnecessary human interaction and labor. In some cases, it can even help support medical efforts. 
In some cases, by examining subtle facial features, facial recognition software can determine how specific genetic mutations lead to specific syndromes. The technology may be faster and cheaper than traditional genetic testing.
  • Easy to integrate.
Face detection and face recognition technologies are easy to integrate, and most solutions are compatible with most security software.

Disadvantages of facial recognition

As with any technology, the use of facial recognition has potential drawbacks, such as threats to privacy, violations of rights and personal freedoms, potential data theft and other crimes. There is also a risk of error due to technical flaws.
Most people believe that the biggest drawback of facial recognition technology is the threat to personal privacy. In fact, several cities have considered or will ban law enforcement, including real-time facial recognition surveillance using San Francisco, Cambridge, Massachusetts, and more. These municipalities believe the risks of using the technology outweigh the benefits. 
In its testing activities, the city wants to determine the accuracy of the system while grappling with how to deal with people who mask their identities to hide them and other issues. In addition, a democratic society must define the legal basis for facial recognition for the general population and when it makes sense to use the technology across the board.
The technology is not as effective as white males in identifying people of color and women. One reason for this is that the data sets that the algorithms are trained on are not as robust for people of color and women. Until this issue is corrected, there are concerns about the consequences of using the technique to misidentify people. 
There are also issues that need to be addressed that could cause the technology to fail when a person changes appearance or the camera angle is not quite right (although they are working on identifying a person by their earlobe alone). 
Another potential drawback is the storage of sensitive personal data and the challenges that come with it. Just last week, we had news that a database containing facial scans used by banks, police forces and defense companies had been compromised.
Will individuals be comfortable with the invasion of their private privacy, and will facial recognition technology continue to offer more and more convenient and secure methods?
Third, biometric data comes with its own security risks. Unlike passwords, biometric data cannot be changed. If my fingerprint data is compromised, it's not something I can "reset" like a password. Worse yet, your face can be scanned anywhere, anytime, without your consent. This means that your biometric data may actually be stored in a series of databases whose security measures may be inadequate.
facial recognition time and attendance is known to work relatively well on white and male faces, and has a high inaccuracy rate for people of color (especially women). This means that minority populations, who already have less access to services and amenities, will encounter additional barriers when authorities use facial recognition in these situations.
Not only does facial recognition discriminate against people of color, it disproportionately targets marginalized populations. In law enforcement settings, facial recognition is primarily used in communities that are already over-regulated. For example, in Italy, the police facial recognition software database contains 2 million images of Italians compared to 7 million images of refugees and immigrants. As a result, this technology is likely to be used in a way that perpetuates the way in which certain groups of people are already disproportionately targeted.
  • Threat to personal and social privacy
The threat to personal privacy is a major drawback of facial recognition technology. People have an aversion to having their information recorded and collected and uploaded.
Privacy has been an ongoing social concern since the beginning of time, and some areas have blacklisted facial recognition technology, such as San Francisco, California. In these cases, police officers can use video recordings from personally owned security video devices, but they cannot use real-time facial recognition software. 
  • Imposing personal freedom
It is always painful to feel that once my facial information is recorded and scanned, others can monitor and judge our daily lives at any time.
In addition to this, the police will also use facial recognition technology to pull out the face information from the database and conduct a virtual scenario of a crime, so that each of us can become a "suspect".
  • Creating data vulnerabilities
There are also concerns about the storage of facial recognition data, as these databases can potentially be breached. 
During the previous hacking spree, hackers broke into banks, police stations, and defense companies. From these institutions, they obtained facial information from people recognition scans
Providing opportunities for fraud and other crimes
At HFSecurity, we are always working on new ways to get employees back to work and customers safely back on premises. Contact our team to learn more about the following technology solutions that help with security identification and people management for businesses, venues and public institutions.
Lawbreakers can also use facial recognition technology to commit crimes against innocent victims. They can collect personal information from images, videos from facial recognition scanning technology and use this personal information to commit identity fraud
With this information, thieves can take out credit cards and other debts or open bank accounts in the victim's name, or even use the victim's identity to build a criminal record.
In addition to fraud, bad actors can use facial recognition technology to harass or stalk victims.

For example, a stalker could collect photos taken in public places and perform a reverse image search based on the photos to collect personal information about the victim.
In addition, because technology crimes are moving faster than the law, people may become victims before the activity is considered a crime. 
  • Imperfect technology
Facial recognition is not perfect. For example, it is not as effective as white males in identifying women and people of color. Facial recognition technology works relatively well on white and male faces, while it has a high inaccuracy rate for people of color (especially women) This means that minority populations, who already have less access to services and amenities, will encounter additional barriers when authorities use facial recognition in these situations.
The technology relies on algorithms to perform facial matching. These algorithms are more robust to white males than other groups because the database contains more data on white males than females and people of color. This can create unintentional bias in the algorithms.
There is an inherent danger of false positives. Facial recognition software can incorrectly identify someone as a criminal, which can lead to an arrest. 
This issue is inflamed when you add that there is a struggle between the technology and people of color, which increases the likelihood of racial profiling charges. 
  • Technology can be fooled
Some external factors such as camera angle, lighting level, image and video quality can affect the ability of facial recognition technology to recognize faces.. People who disguise or slightly alter their appearance can also get away with facial recognition technology. 
  • Technology is evolving
As facial recognition technology advances, its challenges will diminish. Other technologies may affect its effectiveness, including identifying body parts or the way a person walks. 
For now, however, the technology's shortcomings and people's reliance on it mean that there is room for facial recognition to evolve and improve.
Massive data storage burden. The ML techniques used in face detection require robust data storage, which is not available to all users.
Detection is fragile. While face detection provides more accurate results than manual recognition processes, it is also more likely to be discarded by changes in appearance or camera angles.
Potential privacy breaches. The ability of face detection to help the government track criminals creates tremendous benefits; however, the same surveillance can allow the government to observe ordinary citizens. Strict regulations must be put in place to ensure fair use of the technology and compliance with human privacy rights.
  • Privacy Issues Associated with Facial Recognition
In addition to the various advantages of facial recognition, there are some problems with this technology.
One of the disadvantages of facial recognition is that this technology also raises serious privacy concerns.
We must collect, process and store our data in a certain way in order to perform facial recognition as efficiently as possible.
However, this also means that personal data is collected from people, and no one can see what it will be used for.
As a result, opponents of facial recognition often claim that the technology is unreasonable from a general privacy perspective because we don't know what will happen to our data.

  • Facial recognition can be expensive
The cost of implementing facial recognition technology on a large scale can also be high.
In fact, not only can the cameras be quite expensive, but a large number of computers and servers must be used, and personnel are needed to maintain these servers and further develop the facial recognition technology.
Thus, this technology also implies huge costs that must be borne by taxpayers.
  • Can take away people's freedom and pleasure
Another problem with facial recognition is that it also deprives people of a large degree of freedom.
f you are in public, you are always worried that a camera is now watching you, and this feeling of being watched can take away a lot of people's fun.
  • Potential for government abuse
While facial recognition technology can be used for many meaningful purposes, it can also be seriously misused by governments around the world.
For example, suppose you live in a country ruled by a dictator.
In this case, the dictator would happily use facial recognition technology to control the country and identify undesirable people who could be sent to prison.
Thus, facial recognition can be a powerful tool that does more harm than good if it falls into the wrong hands.
  • Sensitive data can be stolen by hackers
Another problem with facial recognition is the potential for sensitive data to be stolen by hackers.
We often hear in the media about servers being hacked and millions of users' data being stolen.
his data often contains sensitive information, and if it falls into the wrong hands, nothing good is likely to happen.


  • The technology is not yet mature
While there have been significant advances in the last decade, facial recognition has not matured, so it may take years or even decades before the technology behind facial recognition is fully optimized.
As a result, there may be other technologies that could work better before facial recognition is fully available.
  • Regulations related to facial recognition in some areas
People in many states have also sued the governments that use facial recognition technology.
In many cases, people have been successful and facial recognition is no longer allowed in these areas.
As a result, the expansion of facial recognition technology could also be slowed considerably by lawsuits, so it could take quite a while for this technology to really advance humanity.
At HFSecurity, we are always working on new ways to get employees back to work and customers safely back on premises. Contact our team to learn more about the following technology solutions that help with security identification and people management for businesses, venues and public institutions.
  • Data storage may be problematic
In addition, the storage of our personal data can be highly problematic.
There are many different regulations regarding the proper storage and processing of data.
These regulations vary from country to country/region to region and it may not be possible to create global databases because they will not comply with all global regulations.
Therefore, even if facial recognition is theoretically possible, there are still many practical data-driven issues associated with this concept.
  • Over-reliance on facial recognition can be dangerous
Relying solely on facial recognition as the primary technology for ensuring our security can also become very dangerous.
Yes, it is a promising technology, but we should have some backup plans in place in case facial recognition is not successful for various reasons and possible future problems.
  • The general public may not embrace this technology
The public is also usually skeptical of facial technology.
People usually just don't want to be observed by cameras in public.
As a result, the local population may also not accept facial recognition and may protest the abandonment of this technology.
  • Facial recognition may lead to higher unemployment rates
Because facial recognition can help automate processes and make them more efficient, less manual work may be required in the future, so many people will lose their jobs in the long run.
In turn, unemployment could increase significantly due to the implementation of facial recognition systems.
  • Invasion of privacy
With this technology, the government can track criminals. But at the same time, it can actually track people like you anywhere, anytime.
The ethical and privacy issues are the most critical ones. The U.S. government is known to store a certain number of photos of citizens without their consent, and we don't yet know all of the circumstances.
So even if facial recognition does offer benefits, there is still a lot of work to be done to make the technology 100% fair to use and consistent with privacy.
Recognition Vulnerabilities
  • Facial recognition technology is indeed very accurate, no one can doubt that.
At the same time, subtle changes in camera angles and even changes in appearance inevitably lead to errors. bam - your new haircut makes you invisible to the camera.
So this is a very serious flaw. You can't guarantee that a person will stand still and face the camera, so the results aren't always correct. And if the person has changed their appearance, it's almost impossible to recognize them.
