  • Patent number: 10880330
    Abstract: System and method for detecting an infected website are disclosed. A semantic finder receives top-level domains and identifies keywords of the top-level domains representing a predetermined semantics. The keywords are compared with irrelevant bad terms to find at least one irrelevant term. An inconsistency searcher searches the top-level domains and detects at least one fully-qualified domain name carrying the at least one irrelevant term. A context analyzer evaluates context information associated with the irrelevant term, identifies at least one frequently-used term identified in the context information, and determines whether the at least one frequently-used term is unrelated to a generic content of the at least one fully-qualified domain name An irrelevant bad term collector extracts the at least one frequently-used term unrelated to the generic content and adds the extracted frequently-used term to an irrelevant bad term list for detecting the infected website.

  • Patent number: 10796190
    Abstract: A sensor may measure light reflecting from a multi-layered object at different times. A digital time-domain signal may encode the measurements. Peaks in the signal may be identified. Each identified peak may correspond to a layer in the object. For each identified peak, a short time window may be selected, such that the time window includes a time at which the identified peak occurs. A discrete Fourier transform of that window of the signal may be computed. A frequency frame may be computed for each frequency in a set of frequencies in the transform. Kurtosis for each frequency frame may be computed. A set of high kurtosis frequency frames may be averaged, on a pixel-by-pixel basis, to produce a frequency image. Text characters that are printed on a layer of the object may be recognized in the frequency image, even though the layer is occluded.
