  • Patent number: 11422971
    Abstract: In an SDN environment, data is migrated after checking whether the data conforms to a legal system of a migration destination. A control device changes a communication setting between first and second servers based on migration destination information and migration source information received from the first server and SDN setting data on a communication setting of the SDN stored in advance. The first server receives data on the legal system and determines whether the data conforms to the legal system to thereby determine whether the data can be migrated, or not. The control device executes a change in the communication setting when it is determined that the migration is enabled from the first server. The first server transmits data stored in a first storage unit to the second server according to the changed communication setting and the data is stored in a second storage unit.

  • Patent number: 10476733
    Abstract: Even if a user ID of a target user is not stored in a cooperation destination Web site, it is possible to access the cooperation destination Web site by use of a user ID of a cooperation source Web site. According to a typical embodiment, a cooperation source application calls up a log-in API of a cooperation destination Web server, based on information including the user ID. The log-in API records the information including the user ID as redirect information, creates a redirect token, and adds the redirect token to a URL of a guide application to send the URL. Based on the sent URL, the cooperation source application redirects access to the guide application. When the redirect information identified by the redirect token included in the URL is recorded, the guide application creates a log-in cookie based on the user ID included in the redirect information, and redirects the access to a cooperation destination application.
