Face Recognition for Passengers:
1. Why is face recognition necessary in airport recently?
Modern airport ID verification is increasingly integrated with facial biometric technology, enabling automated identity authentication at various stages such as check-in, baggage drop, security, and boarding. A prime example is the U.S. Customs and Border Protection’s deployment of its Biometric Facial Comparison system across 238 airports, streamlining passenger ID verification with advanced face-matching tools.
Security professionals are highly vigilant about the growing risks posed by deepfakes and presentation attacks, where individuals may attempt to deceive biometric systems using high-resolution photos, recorded videos, or lifelike masks. These sophisticated spoofing methods challenge the reliability of facial recognition technologies, prompting the need for advanced anti-spoofing and liveness detection measures.
Despite airports being regarded as highly controlled and secure environments, biometric systems must be robust enough to detect and prevent sophisticated spoofing attempts to truly ensure safety. Without accounting for these potential threats, even the most advanced ID verification technologies cannot be deemed fully reliable or trustworthy.
ID verification technologies such as KBY-AI Face SDK combat these security challenges by utilizing advanced liveness detection algorithms designed to confirm that the subject being scanned is a real, physically present individual rather than a fraudulent replica. This critical layer of defense enhances the integrity of biometric systems by actively detecting and rejecting spoofing attempts.
These ID verification systems empower facial recognition kiosks to conduct detailed assessments by monitoring subtle micro-expressions such as blinking, leveraging 3D depth-sensing technology, and analyzing surface texture patterns to accurately differentiate a genuine face from a static photograph. Such multi-faceted verification techniques significantly enhance the robustness of identity authentication processes.
2. Who is true pioneer in this field?
Singapore’s Changi Airport stands as a global leader in aviation innovation, seamlessly integrating cutting-edge ID verification technologies to enhance passenger experiences and operational efficiency. From pioneering biometric systems for passport-free travel to implementing AI-driven ID verification security screening and introducing autonomous cleaning robots, Changi exemplifies the future of air travel.
The airport’s commitment to sustainability is evident in its development of Terminal 5, which will feature one of Singapore’s largest rooftop solar installations, aiming to generate sufficient energy to power the terminal’s operations.
In 2024, Singapore’s Changi Airport became the world’s first to implement nationwide passport-free immigration clearance, utilizing advanced biometric systems for both arrival and departure processes. This initiative, part of the Immigration & Checkpoints Authority’s New Clearance Concept, allows eligible travelers—including Singapore residents and foreign visitors—to clear immigration using facial and iris recognition, significantly reducing clearance times and enhancing travel efficiency.
Passengers, including foreign visitors who register their biometric data at dedicated kiosks in advance, can now complete immigration procedures using only fingerprint or facial recognition—eliminating the need to present a physical passport. This streamlined ID verification process greatly simplifies traveler throughput while maintaining high security standards.
By the end of 2024, the biometric clearance system was fully operational across all four terminals, reducing the average immigration processing time from 25 seconds down to approximately 10 seconds. This efficiency boost reflects a major step forward in speeding up passenger flow without compromising security.
The Immigration & Checkpoints Authority (ICA) of Singapore has announced plans to automate immigration clearance for 95% of travelers by early 2026. This initiative is part of the New Clearance Concept (NCC), which aims to streamline and enhance the efficiency of border processing through advanced automation technologies.
This achievement results from a combination of ID verification technologies, including facial recognition cameras, automated gate barriers, and seamless integration with national databases, all working together to facilitate smooth and secure traveler processing. These interconnected systems enable efficient identity verification and border control with minimal manual interventionBi.
Biometric Document Authentication(ID verification OCR Solution):
More and more immigration checkpoints and airline check-in desks are now outfitted with biometric document readers capable of scanning not just the machine-readable zone (MRZ) and barcodes, but also extracting data from embedded RFID chips. This enhanced capability improves the accuracy and speed of ID verification during travel processing.
For instance, the KBY-AI’s Document Reader SDK can authenticate an identity document in roughly three seconds by capturing all essential information—including data stored on the RFID chip—and conducting automated fraud detection checks. This rapid and thorough validation enhances both security and efficiency in ID verification processes.
Digital Travel Credentials (DTCs) are playing an increasingly important role in modernizing traveler identification and simplifying the ID verification process. Their adoption is accelerating as they offer a secure, convenient alternative to traditional physical documents in the evolving landscape of digital travel.
A Digital Travel Credential (DTC) serves as an electronic equivalent of a traveler’s passport information, securely stored on a mobile device or in the cloud, allowing it to be presented in place of the traditional physical document. This innovation aims to streamline ID verification by offering a more flexible and accessible alternative for travelers.
The International Civil Aviation Organization (ICAO) has developed three types of Digital Travel Credentials (DTCs), each offering varying levels of digital integration and physical documentation requirements:
-
Type 1 – eMRTD Bound DTC: This type involves a digital representation of the traveler’s identity derived from an existing electronic Machine Readable Travel Document (eMRTD), such as an ePassport. The DTC-VC (Virtual Component) is stored on a device, while the physical eMRTD serves as the authenticating document. Travelers must carry the physical passport during travel.
-
Type 2 – eMRTD-PC Bound DTC: In this model, the DTC-VC is derived from an existing eMRTD and is digitally signed by the issuing authority. The DTC-VC can be stored on a device or in a remote system. The physical component (DTC-PC) is created on a physical device, which may be supplied.
Digital IDs for Trip on Air
Several countries and states are rolling out Mobile Driver’s Licenses (mDLs) and national IDs in smartphone wallet apps, which can serve as identity proof for domestic air travel. In the United States, the Transportation Security Administration (TSA) has approved the use of mDLs from select states at airport security checkpoints. Travelers with an Apple Wallet or Google Wallet digital ID can tap their phone at the Credential Authentication Technology (CAT) reader; the device pulls encrypted identity information and displays it to the officer for verification.
For instance, California’s DMV Wallet app allows residents to store their mDLs on smartphones, which can be used at participating airports for TSA PreCheck. Similarly, other states like Arizona, Colorado, Maryland, and Utah have implemented or are piloting digital ID programs compatible with mobile wallets.
Internationally, the UK government plans to launch a digital ID mobile app, GOV.UK Wallet, by 2025, enabling citizens to store government-issued documents, including driver’s licenses, on their phones securely using features like facial recognition.
These advancements aim to enhance convenience and security in identity verification processes, particularly in the context of air travel.
The Transportation Security Administration in the U.S. has started recognizing mobile driver’s licenses issued by certain states for airport security checks. This new acceptance aims to streamline the verification process for travelers using digital identification methods.
Travelers carrying a digital ID stored in Apple Wallet or Google Wallet can simply tap their phone on the CAT reader, which securely retrieves encrypted identity data. This information is then presented to the officer to confirm the passenger’s identity.
The system is built to reveal only essential details such as name, date of birth, and ID expiration, ensuring privacy during verification. In certain situations, this information is paired with a live photo to verify that the individual presenting the phone is indeed the authorized ID holder.
In 2024, Swissport’s subsidiary Checkport Switzerland launched the MatchBox mobile app for airline check-in, which integrates KBY-AI Document Reader SDK.
With the app, travelers can scan their passports with a smartphone camera and get an immediate confirmation if their documents are acceptable. The SDK scans the RFID chip embedded in the ID, verifies its built-in security elements, and conducts a liveness check to confirm the document’s authenticity. This ensures that the identity document is both genuine and tamper-free.
In just six months, nearly 1.5 million identity documents were checked, with 86% handled entirely by automation—significantly reducing the occurrence of inadmissible passenger cases. This high level of efficiency highlights the system’s capability to streamline border and travel security operations.
Advanced Fraud Detection Tools On-Premise
Even as digital IDs gain popularity, traditional physical identity documents are expected to remain in use for many years and will likely continue attracting fraudulent attempts. Their enduring presence underscores the ongoing need for robust security measures against document-related crimes.
To combat identity fraud effectively, airports have established dedicated document verification stations equipped with advanced tools like large-scale spectral comparators. With this level of scrutiny and technology, attempts at document forgery become nearly impossible to succeed.
In late 2024, Wattay International Airport in Laos enhanced its border security by deploying KBY-AI Video Spectral Comparators. These advanced devices empower officers to more effectively identify counterfeit passports and other forged documents.
This technology enables border officials to inspect travel documents using multiple light wavelengths, revealing hidden modifications or forgeries that standard lighting would miss. Such detailed analysis is crucial for detecting subtle signs of tampering or identity substitution.
Standard IDV Solution in Activation
Let’s now explore the key regulatory standards that currently influence ID verification in aviation. These guidelines play a vital role in shaping how digital and physical ID verifications are conducted across the industry.
IATA One ID
The International Air Transport Association (IATA) promotes the One ID initiative, aiming to create a seamless travel experience where passengers are identified through biometrics just once. This approach eliminates the need for paper documents or personal devices throughout the journey.
In the past few years, the One ID concept has transitioned from an idea to reality through several real-world pilot implementations. These trials are actively demonstrating how biometric-based travel can streamline and secure passenger movement.
In one pilot program between Hong Kong and Tokyo Narita with Cathay Pacific, travelers used a digital ID wallet on their phones carrying their travel details. At the airport, facial recognition technology verified their identities, eliminating the need for physical documents.
This approach led to a 40% decrease in processing times at major security checkpoints. Such efficiency improvements highlight the potential of biometric and digital ID technologies to transform passenger flow.
Notably, the trial employed a decentralized framework, testing two separate digital ID verification wallet solutions where most passenger data remained on their personal devices. This approach aligned closely with privacy standards, ensuring users retained control over their information.
IATA is now calling for faster implementation of digital identity solutions in travel, emphasizing that technological challenges have largely been overcome. They advocate for the widespread adoption of these systems to enhance security and passenger convenience.
In April 2025, IATA launched the Contactless Travel Directory, a resource designed to assist airlines in connecting with multiple biometric and digital identity service providers. This guide aims to simplify the integration process and accelerate adoption of contactless travel technologies.
The objective is to avoid fragmented biometric systems across airlines and airports by promoting interoperability and mutual acceptance of digital credentials. This unified approach aims to streamline identity verification while enhancing traveler convenience and security.
ICAO standards and the Digital Travel Credential
The International Civil Aviation Organization (ICAO) has established global standards governing passports and travel documents, ensuring consistency in features like RFID chips, biometric data formats, and security protocols. These guidelines form the foundation for modern e-passports used worldwide.
ICAO is currently concentrating on developing next-generation Digital Travel Credentials (DTC), with ongoing trials for Types 1, 2, and 3. These efforts aim to modernize air travel identity verification by introducing more secure and flexible digital alternatives.
Despite ongoing trials, mixed outcomes indicate that fully eliminating physical passports for air travel remains unlikely within the next few years. The transition to completely passportless journeys still faces significant challenges before becoming a reality.
ICAO is also shaping the way biometrics are integrated with travel documents, particularly for verifying the identities of airline crew and airport staff. This development enhances security and streamlines personnel access control within aviation environments.
Recently, ICAO revised parts of its Aviation Security Manual to recommend that member countries adopt biometric identification for airport workers and pilot license holders. This move aims to reduce the risk of credential fraud within the aviation sector.
Though not legally mandatory, these guidelines establish a global expectation that biometrics will augment traditional ID cards and licenses in sensitive areas such as cockpit entry and restricted airport zones. This approach promotes enhanced security through layered identity verification.
Government Regulatory Frameworks
Regulations play a crucial role in shaping the deployment of identity verification technologies. Within the European Union, the General Data Protection Regulation (GDPR) designates biometric data for identification as a “special category” of personal information, imposing strict controls on its processing and use.

In 2024, the issue gained prominence when the French data protection agency sought guidance from the European Data Protection Board (EDPB) regarding the use of facial recognition technology in airports. This request highlighted concerns about privacy and regulatory compliance in biometric applications.
The EDPB’s Opinion 11/2024 emphasized that storing passengers’ facial biometric data centrally by airports or airlines generally conflicts with GDPR’s privacy-by-design principles unless robust safeguards are implemented. This stance reinforces the need for privacy-focused system designs in biometric identification.
The guidance supported system designs that keep passengers in control of their biometric data, such as storing biometric templates locally on their devices or using encryption keys held solely by the user. This approach prevents airports from accessing or decrypting sensitive information without consent.
Another important regulation is the EU Entry/Exit System (EES), which mandates that all non-EU visitors provide four fingerprints and a facial photo upon their initial entry into the Schengen zone. Every subsequent crossing is then tracked against this biometric record to enhance border security.
Initially planned for launch in 2022 and then postponed to 2024, the Entry/Exit System (EES) implementation has now been rescheduled to October 2025 due to various technical and coordination difficulties. These delays reflect the complexity involved in deploying large-scale biometric border systems.
Once activated, the system will drive the installation of numerous biometric kiosks throughout European airports, requiring advanced infrastructure to safely handle the personal data of millions of passengers. This rollout demands strong security measures to protect traveler information at scale.
In the U.S., identity verification regulations are currently fragmented across different states and agencies but continue to develop rapidly. This evolving landscape reflects ongoing efforts to balance security needs with privacy and innovation.
The Transportation Security Administration (TSA) functions within the framework of federal privacy regulations and has issued comprehensive guidelines governing its biometric initiatives. These policies aim to ensure both security and the protection of traveler privacy.
Essential policies require that biometric identification remains voluntary, with collected data used exclusively for verifying identity. Additionally, strict cybersecurity protocols are mandated to safeguard this information during both transmission and storage.
Recently, U.S. legislators have raised concerns over the TSA’s growing use of ID verification technology as face recognition, questioning its necessity given the effectiveness of CAT scanners in detecting counterfeit IDs. At the same time, the federal REAL ID Act fully came into force on May 7, 2025, requiring passengers on domestic flights to show a compliant license or passport, compelling states to issue IDs with strict identity verification and anti-fraud protections.
