What is a Biometric Passport or e-Passport?

Though it contains the same basic information as a standard passport, the biometric passport (or e-passport) goes much further, representing a more advanced form of identification.

Thanks to an integrated RFID chip, it can hold much more information while delivering optimal levels of security and privacy. Convenient and reliable, these newer-generation documents provide an efficient means of combatting fraud and identity theft, enhancing travel security, and offering a more streamlined experience for travelers.

What Is a Biometric Passport?

Definition and Key Features

Also called e-passport, a biometric passport is an official proof of identification document issued by a country’s government to its citizens. Recognized across borders, biometric passports – much like their standard counterparts – allow those who hold them to travel internationally.

Biometric passports can contain much more information than optical ones. The data is stored securely on an RFID passport chip embedded in the document. These biometric details facilitate ID verification for the passport’s bearer.

What is a biometric passport likely to improve? E-passports offer a concrete answer to the issues of document falsification and identity theft. They also streamline the check-in process for travelers who can go through airport security quickly and easily by scanning the document to verify their data. Human validation is no longer required.

How Does a Biometric Passport Work?

An electronic passport — or digital passport — features an embedded microchip that can be read by NFC terminals. This chip contains biometric information unique to the passport holder, including a digital image of the person’s face, date of birth, nationality, and other key data. When checking in at an electronic border control system (or e-border), the traveler looks into a camera while scanning their e-passport. The system cross-checks facial measurements against the biometric information stored in their digital passport chip to verify their identity.

The electronic passport works like a contactless credit card, relying on near-field communication (NFC) to communicate with a scanner and transfer information. The integrated chip uses digital signature technology to guarantee the authenticity of the data. It also integrates Public Key Infrastructure (PKI) technology to prevent any alteration, adding another layer of security through encryption.

The Advancements in Passport Security

What is a biometric passport compared to an optical document? An undeniable step forward!

From Optical to Biometric: A Security Evolution

Similar to their recent upgrades, optical passports contain encoded information. The data is stored in a database and linked to the document through optical characters that can be read by suitable border control software. The encoded information includes the traveler’s full name, date of birth, nationality, and passport number. When presented with the passport, a border control agent scans the document, checks it against the database, and confirms the person’s identity before allowing them to enter the country.

With a biometric passport, everything is handled automatically through a contactless microprocessor chip reader and face scanner. All key information is stored in the chip itself (making it much harder to falsify), and the passport data server relies on the system to check its validity. Once the passport holder is matched with the biometric data contained in the document, the barrier opens to let the traveler through. The entire process takes less than a minute, and there is no risk of human error.

Components of a Biometric Passport

What’s a biometric passport’s most compelling advantage? Undoubtedly the numerous security features it contains. E-passports may not be foolproof, but they are technologically complex and include several systems and mechanisms designed to keep the data protected, such as:

• Active Authentication to help prevent cloning
• Passive Authentication to detect any modifications made to the passport chip
• Basic Access Control to secure the communication channel between the passport chip and
  the e-passport reader
• Extended Access Control as an additional safeguard for fingerprint data and iris scans
• RF Blocking material around the cover of the booklet to prevent unauthorized scanning or
  “skimming”
• RUID Feature to prevent tracking by issuing a new random UID every time authorization
  to the data is granted.
  As for the biometric information itself, it depends on the country but usually includes:
• Full name
• Date of birth
• Biographical information (birthplace, etc.)
• Photograph, typically biometric, featuring a 3D map of the holder’s face to be read by
  facial recognition software
• Biometric information, such as fingerprints or iris scans
• Unique passport chip identification number
• Digital signature to protect the data from being altered

Global Adoption and Implementation

The First Biometric Passport

While they are gaining traction and being adopted globally, biometric passports haven’t been around for all that long. They were devised as a result of the International Civil Aviation Organization (ICAO)’s effort to enhance travel document security. In the early 2000s, ICAO implemented facial recognition technology as a standard biometric feature. The foundation for standardizing machine-readable travel documents was outlined in ICAO Document 9303.
Malaysia was the first country to issue a biometric passport using facial recognition data.

Worldwide Adoption

By 2006, the US and over 60 other nations had begun issuing biometric passports to bolster their national security measures and lessen occurrences of fraud and tampering with travel documents. Today, most countries have followed suit, no longer using the technology strictly for travel purposes. From banking to healthcare, biometric identification has become a crucial tool for individual privacy and public safety.

That said, while biometric passports must meet the criteria and standards set by the ICAO, not all countries offer the same level of security. E-passports issued by the United Arab Emirates are considered the most secure, followed (in no particular order) by Sweden, Finland, Germany, Luxembourg, the Netherlands, France, Spain, Italy, Switzerland, Austria, and South Korea. All these give holders access to visa-free travel.

In terms of the measures taken to produce ultra-secure documents, the UK, Thailand, and the USA, for instance, feature a tamper-proof polycarbonate data page. Next-generation e-passports will likely support read-and-write instead of read-only technology. That way, digital passports will be able to store travel information such as eVisas and entry/exit stamps.

The Advantages of Biometric Passports

What is a biometric passport? Above all, it’s a means to identify travelers securely and seamlessly. E-passports protect bearers against identity theft, ensuring optimal privacy.

Thanks to their cutting-edge features, these electronic documents are incredibly difficult to alter or replicate. The system also facilitates international cooperation in terms of passport security, all while minimizing potential delays travelers could encounter at borders.
