BSI Biometrics Standards Presentation Presentation Transcript

  • 1. Biometric standards An overview of biometrics and identity management February 2010 Read more at BSI’s Biometrics website www.bsigroup.com/biometrics
  • 2. The need to identify
    • Every day we are required to identify ourselves
      • Using a bank card with a PIN at a cash machine
      • A password to log on to a computer
      • Using a key to open a door
      • Punching a code into a keypad to enter the workplace
      • Using passwords on the Internet
      • Providing a passport and driving licence as proof of identity
    • We need to be able to accurately IDENTIFY an individual to minimize current issues and threats
  • 3. Current attributes used to identify
    • Name
    • Address
    • Postcode
    • Date of Birth
    • Account no.
    • Passwords
    • PINs
    • Phone no.
    • Mother’s maiden name
    • Passport
    • Birth certificate
    • Driving licence
    • Credit cards
    • Utility bills
    • Membership cards
    • Salary slip
  • 4. Is biometrics the answer?
    • A biometric is part of the person and is not easily compromised through:
      • Theft
      • Collusion
      • Loss
    • Simplifies user management resulting in cost savings
    • Users do not need to remember passwords
    • Users do not need to remember PINs
    • User accounts cannot be shared
    • Easy to use
  • 5. Biometric definition
    • The automated recognition of individuals based on their behavioural and biological characteristics
      • The general meaning of biometrics encompasses counting, measuring and statistical analysis of any kind of data in the biological sciences including the relevant medical sciences
    • The term is derived from the Greek words “bios” meaning life and “metron” meaning measure
  • 6. Biological and behavioural
    • Biological
      • Fingerprint
      • Face (2D & 3D)
      • Iris
      • Vein pattern
      • Hand geometry
      • DNA
    • Behavioural
      • Signature
      • Gait
      • Voice
      • Keystroke dynamics
  • 7. Iris
    • Captures the pattern of flecks on the iris
    • Uses conventional cameras
    • Average 2 seconds for identification
    • No physical contact between user and reader
    Read more about BSI’s biometrics standards development at the Biometrics website www.bsigroup.com/biometrics
  • 8. Face
    • Based upon the geometric shape and position of features of the face
    • Resistant to changes in skin tone, facial hair, hair style, and eyeglasses
    • No active user involvement required in order to perform identification/verification
    • Limited success in practical applications
  • 9. Voice
    • Analyses voice patterns and characteristics of speech e.g. pitch, tone, etc.
    • High user acceptance – perceived as least intrusive biometric technology
    • Easy for end users to implement
    • Ideal for telephone systems/mobile environments
  • 10. Hand geometry
    • Measures the physical characteristics of the user’s hand and fingers
    • Low level infrared light and camera used to capture an image
    • Suited to applications where there is a large user base or users access the system infrequently
    • Systems are easy to use and robust
  • 11. Signature
    • Based on analysis of the dynamics of a handwritten signature e.g. shape, speed, stroke order, pen pressure
    • Generally use pressure sensitive tablets or wired pens
    • User friendly
    • Non intrusive – minimal public acceptance issues
    • Captured signature can be used for digitally signing documents
  • 12. Keystroke dynamics
    • Monitors rate of typing and intervals between letters
    • Verification based on typing rhythm – intruders may guess password but fail to key in with correct rhythm
    • Neither enrolment nor verification disturbs the regular flow of work
    • Low cost – only hardware required is keyboard
  • 13. Fingerprint
    • Variety of fingerprint devices available (silicon and optical)
    • Template constructed by analysing patterns that make the fingerprint (minutiae)
  • 14. DNA
    • Forensic genetics use deoxyribonucleic acid (DNA) profiling in a number of important human identity applications
    • 0.01% of a person's entire genome is unique to each individual
      • This represents 3 million base pairs of DNA
      • 95% of the human genome are non-coding sequences (called junk DNA)
    • Standard profiling systems only exploit the junk DNA to maintain the privacy and civil rights of the donor
  • 15. Multimodal
    • Combination of one or more biometrics
      • Algorithmic level
      • Results level
    • Multimodal is the fusion of results with logic applied
  • 16. Key multimodal facts
    • Can be used to:
    • Improve reliability
    • Make forgery more difficult
    • Make systems more flexible to user characteristics (decreases failure to enrol)
    • Make systems more complex
    • Promote inclusivity
    Input Device Matching Result Input Device Matching Result Fusion Fusion Fusion
  • 17. Verification versus Identification
    • “Are you who you say you are?”
    “ Who are you?” NOT
  • 18. Verification and Identification
    • Verification
      • Involves confirming or denying a person’s claimed identity – Are you who you claim to be?
      • Biometric sample captured and compared with the previously stored template for that user
      • One-to-one comparison
      • Are you who you say you are?
      • “ I am who I say I am”
    • Identification
      • Means establishing a person’s identity from an already established list – Who are you from this list?
      • Biometric sample presented to a system which searches the existing (enrolled) subjects
      • One-to-many comparison
      • Do I know you?
      • “ I am not known to you already”
  • 19. Identification before verification
    • To establish a ‘clean’ database of individuals each individual first needs to be identified
      • One-to-many match is performed against the central database to ensure the individual does not already exist under correct name or any other aliases
    • Once identity is established it can be sufficient to verify the individual as proof of identity only
      • One-to-one match is performed at the point of interface without the need to check back to the central database
  • 20. Key Consideration in a biometric system Current & Future Technology Risk & Requirement Analysis Research & Development User Perception Accuracy & Throughput Integration Performance Business Process Strategy
  • 21. Considerations of adding a biometric system
    • Not all biometrics technologies suit all people
    • In many cases additional hardware is required
    • User co-operation is usually necessary
    • Privacy concerns must be addressed
    • Cost of personal devices in large systems can be significant
    • User education is required
    • Biometric revocation must be considered as biometric data is not secret
  • 22. Capture the legal and political imperatives
    • Ask what additional considerations are there with a biometric application as opposed to any other IT deliverable
      • Privacy?
      • Data access considerations (who and why)?
      • Sensitivity of data?
      • Legislative limitations?
      • User acceptance?
      • Standards compliance?
  • 23. ISO/IEC JTC1 SC 37 Biometrics
    • Currently 25 participating countries and 7 observer countries
    • Liaisons with:
      • JTC 1/SC 17 Cards and Personal Identification.
      • JTC 1/SC 24 Computer Graphics and Imaging
      • JTC 1/SC 27 Information Technology Security Techniques.

  • 24. The benefits of standards for biometrics
    • They foster wide spread utilization of the technology
    • They are a sign of industry maturity
    • They reduce time-to-market
    • They facilitate interchange and/or interoperability
    • They reduce risk to integrators and end users
    • They reduce vendor “lock-in” effect
