  • Patent number: 10178116
    Abstract: Events related to an end-point connected with one or more devices are recorded and collected to observe end-point behavior and determine the risk of unfavorable conduct occurring on a network/system. The analysis may include a behavioral analysis that matches events to behaviors, and scores behaviors along factors or parameters of fraud including opportunity (O), pressure (P), and rationalization (R). Malicious behavior may be anticipated or identified prior to commission, allowing preventative measures to be taken or behavior intercepted within the early stages.

  • Patent number: 5892844
    Abstract: An image forming process system in which an original document which includes characters to be copies is scanned. A desired magnification ratio for magnifying the original document can also be input. Further, the characters in the original document are segmented for magnifying the characters by the desired magnification ratio. This magnification operation is performed such that only the characters in the segments are magnified so that the copied and magnified characters are centered at the segments, and such that a size of the copied document is the same as the size of the original document. An operation may further be provided in which the input desired magnification ratio is based on an operator inputting a minimum distance to be maintained between the characters after the magnifying operation, so that the input magnification ratio is calculated based on this minimum distance.

  • Patent number: 5729618
    Abstract: An image forming apparatus operable with digital image data and capable of outputting equivalents of words spelled in a foreign language. Characters are recognized out of image data optically read out of a document image by a scanner or image data received over a subscriber line. Words are separated from the sequences of recognized characters. The equivalent of each word is searched for and then outputted together with the matching word. Paragraphs are separated from the image data and provided with serial paragraph numbers. The paragraph numbers are added to the image data before the generation of an image.

  • Patent number: 5283664
    Abstract: An image recorder for converting input bilevel image data to multilevel data, executing various kinds of image processing with the mutlilevel data, and then recording the processed multilevel data. The image recorder converts input bilevel image data to M-level data (M being equal to or greater than 2), then requantized to N-level data, and then fed to a printer capable of recording data in three or more levels. The bilevel-to-multilevel conversion is effected in matching relation to the pattern of the input bilevel data. A plurality of bilevel-to-multilevel conversion means of different kinds are provided. The bilevel-to-multilevel conversion system is changed on the basis of the kind of input bilevel data. The M-level data is subjected to edge enhancement, magnification change, and gamma correction. Color image data produced by color separation are processed color by color and then fed to a printer.
