How does the use of facial recognition technology for security affect people's privacy and personal information?

Introduction 

Facial recognition technology is presently emerging as one of the most important technologies being used for security purposes in daily life. The technology works by identifying or confirming an individual based on certain characteristics of his or her face. The face of an individual can be captured using cameras, photos or video, after which the captured image can be analyzed using facial recognition technology. Today, facial recognition technology can be applied in various scenarios such as phone unlocking, confirmation of identity of someone, monitoring of particular areas, and identification by security personnel. 

One advantage of the use of facial recognition technology is that it helps to facilitate speed and ease in the matter of security. In this case, one does not have to go through all those pictures and hours of video oneself, but the facial recognition software will assist in doing it quicker. It would come in handy in cases when security officers need to find someone or investigate something. Moreover, facial recognition would be convenient in the sense that it would not require one to know his password or have some kind of identification with him. 

However, even though there are advantages in facial recognition technology, there are issues regarding individuals’ privacy and data. The issue is that one passes by a camera not aware that his/her face is scanned and processed. In this way, individuals may be asking themselves who gathers data about them and what purpose this data serves. Another question is related to storage time of faces and possible usage of data in other organizations. According to Andrejevic and Selwyn (2022), the emergence of the facial recognition is linked to the development of the wider surveillance technologies in society. With more and more areas using facial recognition, the amount of facial data collected from individuals grows. 

Additionally, the fact that facial data differs significantly from the password is another important issue. In case one loses the password, they are able to change it. However, a person is not able to change his/her face in case someone steals the facial data. Thus, organizations utilizing this technology have a responsibility to ensure that facial data is properly secured. Moreover, ethical and social issues emerge in regard to the need to inform users when facial recognition is employed and give people an opportunity to opt out of the facial scan. 

In general, facial recognition technology is beneficial for security purposes; however, there are several concerns related to the use of this technology. The increasing utilization of this technology requires finding a balance between utilizing the technology to enhance security and ensuring that the privacy of people is protected. This paper will discuss the functioning of facial recognition technology, potential benefits in terms of security, as well as legal, ethical, social, and security concerns associated with the use of facial recognition technology. Special attention will be paid to privacy issues. 

What is Facial Recognition Technology? 

Facial recognition technology identification is a way of identifying an individual based on their facial attributes. The technology can be used via surveillance cameras as well as via photos and video footage. According to Andrejevic & Selwyn (2022), the technology has increased to such a level that facial recognition is also viewed as being part of surveillance. As the technology continues to be adopted by different places, the number of faces being recorded will continue to increase. 

This process works due to analyzing various characteristics of a person's face and then using these characteristics to identify the person. Once the picture or video of a face is collected by the camera, this information can be analyzed and compared with previously stored information about this person. In case of matching, it becomes easier to identify who the person is. This technology may be helpful as computers have the ability to process a huge amount of information much faster than a person. 

There are various situations when this technology can be applied. It can be used for various purposes such as security or identification and gaining access to some devices and places. An example of such situation can be smartphones which allow you to open your phone just by showing your face and not using the password. Another way to apply this technology is in security systems where you can identify people through camera footage. 

Nevertheless, the increasing deployment of the technology also raises issues of privacy of the collected data. People may not necessarily know that their faces are being captured or analyzed. Furthermore, as the number of cameras and agencies employing facial recognition increases, the amount of stored facial data will grow even more. Hence, it is not only crucial to understand the basics of facial recognition itself, but also the methods of storage and protection of collected data. 

Facial Recognition and Security 

One more factor behind the growing popularity of facial recognition is the possibility of using it to increase the security of the surroundings. It may prove useful for identifying a person who is possibly engaging in some criminal behavior or helping security personnel analyze the recorded video faster. As Ludwig (2026) states, the police have started utilizing drones and other equipment that can record huge amounts of video footage. Facial recognition can help in analyzing the recorded data and finding out the identity of people. However, more surveillance may lead to an everyday monitoring of people who do not commit any crimes. 

Privacy and Personal Information 

Among the other concerns associated with facial recognition technology is the aspect of privacy. As mentioned by Leong (2019), the technology makes it possible for individuals to identify others using cameras. This raises concern because an individual’s facial features cannot be changed or altered. For example, if one forgets his or her password, another one can be created. However, this is not possible when it comes to one’s facial features. Moreover, there might be no way for one to be aware that his or her facial features have been captured. It brings up the issue of whether consent must be obtained for capturing one’s facial features. 

Ethical and Social Concerns 

There are also some social and ethical considerations regarding how facial recognition technology impacts individuals in public spaces. An individual might react in a different way to visiting a certain place if he/she knows that the visit will be monitored and their identity will be known. According to Kahn (2026), mask-wearing at protests is associated with protection of one's identity and can be linked to concerns related to the use of facial recognition. Furthermore, the issue of privacy in connection with technology that uses real photographs and videos is raised by Turner and Martin (2026). 

Current and Future Use 

With further advances in the field of artificial intelligence, it is possible that facial recognition technology may spread even more widely in the future. This can be illustrated by the increasing number of cameras and other devices that can be employed by both private companies and the government. According to Shakespeare (n.d.), there is talk about using AI facial recognition cameras and issues related to privacy in connection with it. Given that the technology has not been fully developed, regulating and protecting the data gathered by means of such technology will be necessary. 

The development of facial recognition technology may be further extended to other areas of human life. Business entities can employ this technology to strengthen their security systems, while governmental bodies can use this technology for the purposes of identification or when reviewing surveillance footage. In addition, this technology may be increasingly used on personal gadgets and where the identification of individuals is needed. All of these applications may speed up some processes, but may increase the amount of facial information available. 

One other issue that may arise in the future would be educating people about the presence of the technology. Individuals may use a security camera without ever knowing that the software would also be recognizing his or her face. The organization ought to provide reasons for the use of the technology and what kind of information it collects and how long it intends to hold such information. It is also necessary to restrict who has access to facial information to prevent misuse of it. 

Generally, the future of facial recognition technology depends on the control of such a technology as it keeps on evolving. The development of new technologies can enhance the effectiveness of facial recognition and increase its accuracy, while privacy of individuals would be taken care of. Clear guidelines in the collection, storage and use of facial information may allow society to enjoy some benefits of facial recognition without totally sacrificing privacy. 

Conclusion 

In general, facial recognition can be treated as technology, which is useful when it comes to enhancing security; however, it raises some questions in regard to the future of personal data. People might not even be aware of the fact that their recognition was performed by means of this technology. Furthermore, personal data can be saved for a very long period of time or used without the consent of the person himself or herself. The problem of protection of personal privacy with the help of this technology will become increasingly relevant over time. 

With the growing use of facial recognition, it is vital for organizations to be responsible for the information collected. It is necessary for people to get a better insight into when facial recognition takes place and how their information is further used. It is crucial for companies and governmental agencies to make sure that facial data is stored securely and is only used for the designated purpose. Stronger security and proper regulations could minimize the possibility of stealing and misuse of personal information. 

Also, there must be a balance between enhancing the security system and maintaining the privacy of people. The use of facial recognition will enhance speed in the identification of people and might help increase the security in some areas; however, security does not mean that people should lose complete control of their personal information. It should be considered if the use of facial recognition is really necessary. In all, the use of facial recognition will definitely increase in the future as time goes by and as technology advances.
