  • Publication number: 20210365431
    Abstract: In an SNS server (103) corresponding to a false submission filter device, an event specifying unit (604) analyzes contents of a submission informing of an occurrence of an event and specifies a location (721) of occurrence of the event. A query destination specifying unit (605) searches a query destination database (613) and specifies a query destination corresponding to the location (721) specified by the event specifying unit (604). A query unit (606) transmits a request for checking the presence or absence of occurrence of the event from the observation result of one or more machines to the query destination specified by the query destination specifying unit (605). The query unit (606) receives a response to the request. A result reflecting unit (607) determines whether the contents of the submission are true or false from a check result indicated by the response received by the query unit (606).

  • Patent number: 9773562
    Abstract: A storage apparatus includes a flash memory that includes multiple blocks; and a control portion that reads data written in the block and writes the data into the block. The flash memory includes one block set having n pieces of the blocks including BR1 to BRn. A write data and a write flag are capable of being written into each of blocks BRi, the write data being written in accordance with a request, the write flag indicating that the write data has been written into a target block BRj. In accordance with a write request, the control portion performs an erasure process, a first write process, and a second write process. The erasure process erases the data including the write data and the write flag. The first write process writes the new write data into the block BRl. The second write process writes the write flag into a block BRm.
