Abstract: A traceability information management server includes: a transaction reception part that receives transaction data from a user client, the transaction data containing information on a completed process in distribution of a product and a concerned party in the completed process; an access right information generation part that generates access right information, the access right information being information on a relation between the completed process, the concerned party in the completed process, and a predetermined access right of the concerned party; an access right determination part that identifies, based on the access right information, information on a process in the distribution to which a sender of the received information provision request from the user client has an access right; and an information transmission part that transmits the identified information on the process to the user client that has sent the information provision request.

Abstract: An application executed at a user terminal with a touch screen displays, on the touch screen, a UI in which a user-side UI for accepting a touch operation by a user and a store-side UI for accepting a touch operation by a staff member of a store are placed, as a settlement UI for settlement of a currency amount of a digital local currency. The application judges whether time during which the touch operation on the user-side UI and the touch operation on the store-side UI are simultaneously continued has reached a specified period of time or not. If the judgment result is true, the application displays a settlement completion notice on the touch screen.

Abstract: A machine system includes a physical machine, a memory pool, and a memory pool management machine. The memory pool management machine manages, with respect to a memory region of the memory pool, an allocated region, a cleared region, and an uncleared region. When generating a virtual machine, a hypervisor in the physical machine sends a memory allocation request to the memory pool management machine. When a response, to the request, received from the memory pool management machine includes an address range belonging to the uncleared region, the hypervisor clears the memory region of the address range belonging to the uncleared region and then generates the virtual machine.
