  • Patent number: 9836602
    Abstract: To prepare computing devices (e.g., running Windows NT-based operating systems) for offline scanning, without the need for removable media, such as CDs and USB devices, and for users to modify the BIOS settings, parameters regarding a protected-mode operating system and the computing device are collected and verified while the protected-mode operating system is running on the computing device. A kernel of an alternate operating system (e.g., a Linux operating system) can be mapped to the memory of the device, shutdown of the protected-mode operating system can be initiated, a system environment for the alternate operating system kernel can be prepared, and control of the computing device can be transferred or passed to the alternate operating system kernel.

  • Patent number: 9813873
    Abstract: A mobile device tracking prevention method and system includes monitoring a mobile device for movement, determining whether an operating state of a wireless module of the mobile device should be adjusted when movement of the mobile device is detected, and controlling the operating state of the wireless module based on the determination. One or more of the actual geographic location of the mobile device, network IDs broadcasted by nearby network access points, and signal strengths of the access points as detected by the mobile device can be monitored to detect movement of the mobile device. Changes to any of these may be indicative of movement of the mobile device, which may serve as the basis for enabling or disabling the wireless module to prevent tracking of the mobile device without sacrificing user productivity.

  • Patent number: 9798802
    Abstract: In a system for extracting policy information from text, a processor analyzes if the text is relevant to a top-level category, and then determines if at least a portion of the text is relevant to categories and subcategories within a taxonomy of categories and subcategories related to the top-level category. If at least a portion of the text is determined to be relevant to the category/subcategory, a classifier extracts policy information associated with the category/subcategory. Using text that includes a known policy the classifiers can be trained to correctly recognize categories/subcategories, and the values associated therewith.
