Abstract: A system using edge computing is enabled to efficiently acquire data of an acquisition target without fail. A data search server KSV includes an industry information table 221 which stores an edge ID of an edge server operated and managed by a company/body, the edge ID being correlated with an industry ID which identifies an industry, and an ID of the company/body belonging to the industry. When a data acquisition request designating the industry ID is received from a user terminal, edge servers correlated with the designated industry ID are searched from the industry information table 221, and sensing data is acquired from the searched edge servers and transmitted to the user terminal of the source of the request. Menu screen information is sent from the data search server KSV to the user terminal, and displayed, and a user is enabled to select an industry on the menu screen.

Abstract: According to one aspect of the present invention, a data management device creates a shared storage area accessible only by the first user and the second user. The data management device further generates a new data file as shared data of the first user and the second user by extracting, according to a shared use condition of data for the second user that is set by the first user, at least some data of at least one data file among one or more data files of the first user, said one or more data files being stored in a dedicated storage area isolated from the second user. Further, the data management device stores the generated shared data in the shared storage area.

Abstract: A communication control apparatus according to one aspect of the present invention determines whether a message to be transmitted from an information processing apparatus include at least one attached file, when the message is transmitted from the information processing apparatus to one or more destinations via a network. When the communication control apparatus has determined that the message to be transmitted includes said at least one attached file, the communication control apparatus acquires approval of transmission of said at least one attached file from an approver, and transmits the message including said at least one attached file to said one or more destinations, on condition that approval of transmission of said at least one attached file has been received from the approver.

Abstract: A communication control apparatus according to an aspect of the present invention downloads and acquires, from a center server on a cloud, an approval rule by an approver of upload in upload of a data file to the center server. The approval rule is stored in the center server. When any data file is uploaded to the center server, the communication control apparatus acquires approval of upload of the any data file from the approver in accordance with the acquired approval rule, and uploads the data file to the center server on condition that approval of upload of the data file has been acquired from the approver.

Abstract: The confidentiality of data is maintained in the case of outsourcing analysis of an operation state of a facility. Degree-of-relevance information indicating a degree of relevance in operation between a plurality of apparatuses included in a facility is stored. At the occurrence of a failure in a first apparatus included in the plurality of apparatuses, a second apparatus having a degree of relevance in operation to the first apparatus equal to or greater than a preset first threshold is selected from the plurality of apparatuses based on the degree-of-relevance information, and the log data relating to operation states of the first apparatus in which a failure has occurred and the selected second apparatus are selectively read from a first memory storage, and the read log data is transmitted to a data user via a network.

Abstract: The confidentiality of data is maintained in a case where analysis of an operation state of a facility is entrusted to the outside. Time difference information in operation between the manufacturing apparatuses (RB1), (RB2), . . . , arranged on the production line (LN) is stored for each of the apparatuses, in an inter-apparatus time difference information storage unit (33). At the occurrence of a failure in one of the manufacturing apparatuses (RB1), (RB2), . . . , the operation estimation unit (13) selects, from among the peripheral apparatuses on the upstream side and the downstream side with respect to the manufacturing apparatus concerned, one on the upstream side and one on the downstream side, estimates an operation period of each selected peripheral apparatus associated with the failure, reads log data corresponding to the estimated operation period from the operation history storage unit (31), and transmits the read piece to the external support center (SC).

Abstract: The confidentiality of data is maintained in a case where analysis of an operation state of a facility is entrusted to the outside. An embodiment of the present invention is configured to chronologically store log data in a first storage medium, and store attribute information indicating a relevance between a type of a failure expected to occur in a facility and each of a plurality of data users; The embodiment is further configured to select, at the occurrence of a failure in the facility, a data user who has a relevance to a type of the failure from among the plurality of data users based on the attribute information, selectively read log data relating to an operation state of the facility in which the failure has occurred, and transmits the read log data to the selected data user.

Abstract: In a system using edge computing, a technology for performing efficient storage management is provided. A storage management apparatus communicable with a plurality of edge servers each including a storage part storing data and access log information to the data is configured to acquire the access log information from each edge server; to decide, based on the acquired access log information, whether a state of access to the data stored in the storage part of each edge server meets a preset criterion; and to execute control to select, as a transfer target, data in the state of access which is decided as failing to meet the criterion, and to transfer the data to another storage part different from the storage part in which the data is stored.
