Just as each type of biometric deployment can have a different impact on privacy, each biometric technology bears a different relation to privacy. Some technologies have almost no privacy impact, and could scarcely be used in any privacy-invasive fashion. Other technologies are much more likely to be associated with privacy-invasive usage, either due to their core operation or due to extrinsic factors.
BioPrivacy Technology Risk Ratings assesses the privacy risks of leading biometric technologies in four key areas:
Verification/identification. Technologies that are most capable of robust identification are rated higher; technologies that are only capable of verification are rated lower.
Overt/covert. Technologies that are capable of operating without user knowledge or consent are rated higher; technologies that only operate with user consent are rated lower.
For
organizations not yet prepared to execute a full Privacy ImpactAssessment
of a biometric deployment or technology, IBG has created areport,
"Biometrics
and Privacy: Assessing Deployment and Technology Risks,"
which provides a framework for understanding privacy issues inbiometric
technologies.
