• Why standards?
• The standards process
• Example of biometric standards
• Report on privacy, health and safety and accessibility
• Accessibility
  • draft taxonomy of issues and design principles
    

Slide 3
Why develop standards?

• For the operator
  • Independence from reliance on a single supplier
  • Simplification of design
  • Improved likelihood of interoperability
• For the supplier
  • Industry-agreed interfaces
  • Informed route to market
• For the end user
  • Best practices in applying new technologies

Slide 4
Types of standard

• Technology
  • Interfaces and protocols
• Processes and quality
  • BS7799
• Managing design
  • BS7000
• Technical Report
  • Review of knowledge and best practice
  • Precursor to work leading to a standard
    

Slide 5
Biometric Standards - origins

• Industry consortia
  • BioAPI Consortium
  • Biometric Working Group (Testing)
• Sector needs
  • ICAO -> ISO -> new committee SC37
• European standards
  • CEN/ISSS Focus Group
  • European Biometrics Forum Special Interest Group
• National standards bodies
  • ANSI (USA), standard for biometrics in finance
• Suppliers
  • Image standards for: finger spectral pattern, hand geometry

Slide 8
Biometrics standards in summary

• SC37
  • WG1: what we mean
  • WG2: transfer of biometric data in a system
  • WG3: encoding biometric data in an interoperable way
  • WG4: selecting the right options in the standards for a specific application, e.g. access control, Seafarer's ID
  • WG5: testing that systems will perform
  • WG6: taking care of the legal and societal aspects
• SC27
  • Ensuring that systems are secure
• TC68
  • Management of biometric systems in financial applications

Slide 9
Appearing this summer …

• 19784-1 BioAPI specification
• 19785-1 CBEFF exchange format specification
• 19785-2 CBEFF - operation of Registration Authority
• Data interchange formats
  19794-2: Finger Minutiae
  19794-4: Finger Image
  19794-5: Face Image
  19794-6: Iris image

Slide 10
Accessibility

• Technical Report WD of 24714
  • 'Cross-Jurisdictional and Societal Aspects of Implementations of Biometric Technologies'
  • Privacy, Health and Safety, Accessibility
  • Commercial applications
• Testing
• ? Image standards, CBEFF, BioAPI

Slide 10
Taxonomy of accessibility issues

• Absent physical body parts or behavioural features
• Unusable physical body parts or behavioural features
• Insufficiently consistent presentation of biometric feature
• Accelerated drift in physical or behavioural features

• Difficulty in access to biometric reader

• Inability to understand or follow the instructions
• Psychological conditions preventing correct operation

• Conditions resulting in disproportionate use of resources

Slide 12
Design principles

• Maximise usage, minimise discomfort.
• Needs of disabled subjects to be considered from the start of design
• Thoroughly test before deployment

• Wherever practicable and feasible,
  offer a choice of biometric systems, not disadvantaging the disabled
  offer an alternative which does not result in an inferior level of service
  offer to repeat registration if problems recur

• Adequate training for subjects with a disability
• Staff trained to work with disabled subjects

• System should not store details of a subject's disabilities without consent
• The rights to privacy of a disabled subject should be respected
