Abstract:
An intermediation method used in an intermediation system that includes an intermediation device determining a permission for application services requiring user authentication on a network, where in response to a user request, a first account used for a first service and a second account used for a second service, and a registration request for using the linking service linking the first application service and the second application service are associated with each other, when the two accounts are valid, as accounts usable in a linking service, an association between the first and second services is stored in the intermediation device, and when the user makes a request to use the linked services, that use is controlled by a query to the intermediation device regarding whether the account is associated as able to use the linking service.
Abstract:
A smart meter includes: a power supply control unit which causes stoppage of a supply of power passing through the smart meter to an television and so on, when an RD command to stop the supply is received; a first communication unit which performs a first communication through which the RD command is received; a second communication unit which performs a second communication; and a communication control unit which: causes the performance of the first communication before the RD command is received; and prohibit the performance of the first communication and cause only the performance of the second communication, after the RD command is received.

Abstract:
A content reproduction system includes an information processing terminal (102) and a secure device (103). The information processing terminal (102) receives a copyright protection application program (315) from an application distribution server (113). The copyright protection application program includes a first program having a first execution format executable in the information processing terminal (102) and a second program having a second execution format different from the first execution format and executable in the secure device (103). The second program is encrypted with a program key (515) held in the secure device (103). By extracting and executing the first program, the information processing terminal (102) extracts the second program and transmits the second program to the secure device (103). The secure device (103) receives the second program from the information processing terminal (102), decrypts the second program using a program key stored in a key storing unit (520), and executes the second program.
