  • Patent number: 8340361
    Abstract: A biometric authentication system, authentication client terminal, and biometric authentication method are provided to reduce an expected value of the number of inputs of biometric data for authentication, while effectively preventing forgery. In a biometric authentication system, prior probabilities of enrolled users un and non-enrolled user u0 are previously set. 1:N matching is performed between feature data of a claimant v and matching feature data. The matching score is calculated for each enrolled user un. A ratio of the likelihood v=un to the likelihood v?un is calculated for each enrolled user un using the calculated matching scores. Posterior probabilities of the enrolled users un and non-enrolled user u0 are calculated, using the likelihood ratios, and the prior probabilities of both the enrolled users un and the non-enrolled user u0. Then, determination is made by comparing each posterior probability with a first threshold.

  • Patent number: 8340395
    Abstract: The invention relates to a defect inspection apparatus in which images of mutually corresponding areas in identically formed patterns on a sample are compared to detect mismatched portions of the images as defects. The defect inspection apparatus includes an image comparator that creates a feature space with the use of feature quantities calculated from pixels of images acquired under different optical conditions and detects outlier values in the feature space as defects. Thus, the defect inspection apparatus can detect various defects with high sensitivity even if there are luminance differences between images of identical patterns which are attributable to the difference in wafer pattern thickness.
