Biometric ID To Become Part Of Passports

Facial recognition was selected as the globally interoperable biometric for machine-assisted identity confirmation with MRTDs. In a comprehensive analysis of various available biometrics, the face rated highest in terms of compatibility with key operational considerations, followed by fingers and eyes. The face has long been used by border-control authorities and airport staff to confirm identity through photo IDs. Facial-recognition technology automates this process, using a camera to capture the image of the face, while a computer validates facial characteristics.

ICAO has selected high-capacity, contactless integrated circuit (IC) chips to store identification information in MRTDs. Compressed images of one or more biometrics would require more data-storage capacity than is now available on bar codes.

The ICAO blueprint, set out in technical reports and specifications, will assist all 188 member states to implement a worldwide, standardized system of identity confirmation. Members will have the option of using one or two secondary biometrics to supplement facial recognition for personal identification.

A modified public-key infrastructure scheme will protect data stored in the IC chip against unauthorized alteration or access.
