Facial recognition advances globally, reigniting debate on privacy and surveillance
Found in airports, mobile phones, stadiums, and even payment systems, facial recognition promises enhanced security and convenience. At the same time, experts warn of risks regarding privacy, the storage of biometric data, and the use of this information by governments and companies.
Facial recognition has evolved from a futuristic technology into a part of daily life for millions of people. Today, it is found in smartphones, immigration control systems, payment platforms, security cameras, and sporting events. As governments and companies expand its adoption, the debate surrounding privacy, data protection, and the limits of mass surveillance is also growing.
Speaking on the program *Infobae en Vivo*, analyst Emmanuel Ferrario stated that the technology is already widely deployed and can offer significant gains in security and efficiency. However, he argued that its use must be accompanied by clear regulations, oversight, and mechanisms to prevent abuse.
According to Ferrario, approximately seven out of ten governments already use some form of facial recognition system in their operations.
The technology's presence extends far beyond public safety; it also appears in mobile phones, airports, supermarkets, and even payment solutions.
As an example, the analyst cited South Korea, where a system called FacePay allows consumers to make purchases using only their faces for authentication.
In practice, this type of solution uses biometric data to uniquely identify an individual, eliminating the need for cards, passwords, or cash.
Ferrario notes that the popularization of this feature began nearly a decade ago when Apple introduced Face ID on iPhones.
Initially, the technology was used to unlock the device. Over time, it expanded to authorize payments, access apps, and validate various digital transactions, making facial recognition a common tool for millions of users.
Supermarkets and companies are also adopting the system...The private sector has likewise been expanding its use of this technology. In the United Kingdom, for example, some supermarket chains use internal facial recognition systems to identify individuals involved in thefts previously recorded at other locations within the same company.
According to Ferrario, when a customer is identified by cameras during a theft, their biometric data may be stored in the chain's database to facilitate future identification.
This type of application illustrates how facial recognition has moved beyond exclusive government use to become part of loss prevention and corporate security strategies.
Benefits for public safety...In the security sector, Ferrario states that the technology offers significant advantages.
The systems can assist in identifying fugitives, missing persons, kidnapping victims, or vulnerable individuals.
Furthermore, facial recognition can accelerate investigations and provide biometric evidence for legal proceedings.
The analyst points out that eyewitnesses often make mistakes due to the stress or pressure experienced during a crime. In contrast, biometric identification tends to offer a higher level of accuracy when used correctly and combined with other investigative elements.
Another cited benefit is speed.
At airports and stadiums, for example, facial recognition can significantly reduce the time required to verify user identities. According to Ferrario, some systems can speed up access processes by up to 30%.
World Cup experience showed adoption still depends on user choice...Ferrario also commented on information released during the World Cup regarding the use of facial recognition for stadium entry.
He noted that although FIFA presented this option as an innovation available to fans, its use was not mandatory.
After speaking with people who attended tournament matches, the analyst concluded that many fans chose to use only the traditional QR code to enter the stadiums, opting against facial recognition.
This instance demonstrates that, in some cases, the technology still coexists with conventional authentication methods.

Facial recognition in residential complexes...Technology has made its way into residential complexes, and there is a curious case worth recounting here...A residential complex in a certain region of Brazil decided to adopt a type of magnetic key system; it was more convenient because residents simply had to hold the magnet embedded in their keys near the reader to open the door—but people kept losing these magnetic keys. After some time, the decision was made to switch to biometrics; this solution was certainly more suitable, practical, and secure. Yet, that still wasn't enough; now, the trend of the moment—facial recognition—has been adopted. The administration decided unilaterally (and dictatorially) that all residents must use facial recognition exclusively, or else face being unable to access their homes within the complex...The moral of the story? The resident is reduced to cattle in a pasture—devoid of autonomy and subservient to the complex's overseer—writes the *mundophone* portal.
Privacy remains the primary challenge...Despite the operational advantages, Ferrario believes the major debate centers on the fate of the collected biometric information.
Issues such as image retention periods, who manages these databases, which institutions can access them, and what mechanisms exist to prevent misuse still lack uniform answers in many countries.
These concerns are becoming increasingly relevant as governments and companies expand the use of the technology in public spaces and private services.
For this reason, experts argue that the expansion of facial recognition must be accompanied by specific legislation, independent audits, and transparent policies regarding the collection, storage, and sharing of biometric data.
There is a consensus among both proponents and critics that facial recognition will continue to advance in the coming years. The challenge will be to strike a balance between the benefits offered by the technology and the protection of fundamental rights regarding privacy and individual freedom.
