  • Constraint-based multiuse certificates
    Patent number: 10798129
    Abstract: Multiuse certificates (e.g., wildcard certificates) can be associated with policies that specify one or more computational constraints, e.g., limited processor power, limited access time, limited access to file system usage, or limited memory access. An application associated with a multiuse certificate can be monitored to ensure that the specified computational constraints are not violated. Upon the computational constraints being violated, the multiuse certificate can be invalidated and/or authentication requests rejected.
    Type: Grant
    Filed: September 11, 2017
    Date of Patent: October 6, 2020
    Assignee: EBAY INC.

  • Water activity determination using near-infrared spectroscopy
    Publication number: 20060043300
    Abstract: A method and apparatus for determining water activity levels of samples by spectral analysis. The method and apparatus facilitate much faster water activity level measurement than prior methods and apparatus. The method may include calibrating a spectral analyzer by correlating samples of known water activity to certain spectral features. A calibrated apparatus according to principles of the present invention may very quickly correlate spectral features of a sample of interest with a water activity level to a high degree of accuracy.
