  • Patent number: 10416970
    Abstract: A program analysis unit of a browser emulator manager exhaustively searches a code by performing syntax analysis of a code included in web content to search a transfer code to another site or a content acquisition code, and specifies at least any of an object and a function and a property of the object used in the code found as a result of the search. Further, the program analysis unit extracts a code having a dependence relationship with the transfer code or the content acquisition code based on at least any of the object and the function and the property of the object thus specified.

  • Publication number: 20190267597
    Abstract: An electrode-separator assembly is provided that can drastically facilitate assembly of a LDH separator-equipped nickel-zinc battery without work, structure, or component for complete separation of a positive-electrode chamber from a negative-electrode chamber. The electrode-separator assembly includes a positive-electrode plate; a negative-electrode plate; a layered double hydroxide (LDH) separator for separation of the positive-electrode plate from the negative-electrode plate; and a resin frame having an opening to which the LDH separator and the positive-electrode plate are fitted or joined. The positive-electrode plate has a smaller face than the negative-electrode plate. The negative-electrode plate has a clearance area that does not overlap with the positive-electrode plate over a predetermined width from the outer peripheral edge of the negative-electrode plate.

  • Patent number: 10391787
    Abstract: An inkjet printer ejects a first ink of a plurality of colors and a second ink. An extractor extracts an underlying layer dot group from ink dots of the first ink of each of the plurality of colors. Such underlying layer dot groups and ink dots of the second ink form a first printing layer. An image dot group including at least the ink dots, of the first ink, other than the underlying dot groups forms at least one additional printing layer. The underlying dot groups are each extracted from the ink dots of the first ink of the corresponding color based on a predetermined extraction ratio.

  • Patent number: 10366236
    Abstract: In accordance with codes of applications, it is determined whether the applications access predetermined privacy information due to permission, a first label is assigned to an application that is determined to make an access, and a second label to an application that is determined not to make an access. The score of each word is calculated such that a high score is set to a word that is included in the text of the description of the application, to which the first label is assigned, more often than in the text of the description of the application, to which the second label is assigned, and a predetermined number of words at the top with regard to the score is extracted. The application whose text of the description includes the extracted word is classified as an application that refers to the permission.

  • Patent number: 10277613
    Abstract: A URL matching apparatus generates partial character string information storing therein, as keys of an associative array, partial character strings obtained by connecting stepwise in order from a character string of an upper layer of a hierarchical structure of one or more reference URLs. The URL matching apparatus generates partial character strings obtained by connecting stepwise in order from a character string of an upper layer of a hierarchical structure, also for a URL to be matched, and for each of these partial character strings of the URL to be matched, searches the partial character string information with that partial character string being a key. Thereby, even if a URL is partially changed, matching is able to be performed at high speed.

  • Patent number: 10242191
    Abstract: A dynamically-loaded code analysis device includes a memory unit, an extraction unit, and a specification unit. The memory unit memorizes dynamically-loaded code information indicating a class structure of a dynamically-loaded code and call method information in which tag information added to user information is associated with a class structure of a code performed for the user information, for each of the dynamically-loaded codes acquired via a network. The extraction unit detects transmission of user information to another device and specifies tag information that matches the tag information added to the user information from the call method information memorized in the memory unit, to extract a class structure associated with the tag information. The specification unit searches the memory unit for dynamically-loaded code information indicating the class structure, to specify a dynamically-loaded code corresponding to the dynamically-loaded code information.

  • Publication number: 20190007439
    Abstract: A network standpoint feature value creating unit classifies access data collected at observation points into each detection target access source and creates network standpoint feature values for each of the detection target access sources. An access source detection unit detects, based on the network standpoint feature value, an access source performs a predetermined continuous access. A point standpoint feature value creating unit creates detection target standpoint feature values that are feature values for each access data collected at an observation point and training standpoint feature values that are feature values for each access data of the access source detected by the access source detection unit. An access detection unit detects access data in which the similarity between the detection target standpoint feature value and the training standpoint feature value is not less than a predetermined value as access data by the predetermined continuous access.

  • Publication number: 20180316696
    Abstract: A browser emulator manager causes a browser emulator(s) to access a website. The browser emulator traces content interpretation and script execution on a browser that have occurred by access to the website. When detecting transfer, the browser emulator records, in transfer information, a transfer method, a transfer source URL, and a transfer destination URL thereof. When detecting the script execution, the browser emulator records, in the transfer information, an execution method and an execution source script thereof. A graph construction unit constructs a directed graph on the basis of the transfer information. Thereafter, a graph analysis unit specifies places of content and a script causing the transfer by tracing the directed graph.
