BIOMETRIC PROTECTION OF A PROTECTED OBJECT

摘要

Multiple biometric samples (180) of an authorized user are associated with protected material (170), and access (250) to protected material (170) is based on a comparison of a sample (210) of a biometric to these multiple protection- samples (180) of the biometric. The likelihood of wrongly- denying access to the material is controlled by the criteria used in the comparison (240) of the access-sample to each protection- sample. The likelihood of wrongly- allowing access to the material is controlled by the criteria used to grant access (370) based on the multiple comparisons. To further control the likelihood of wrongly-allowing access to the material, multiple biometric samples (210) are collected during the access-granting period, and these multiple access-samples (210) are compared to the multiple protection-samples (180).
