Abstract: An information processing device includes: a display means for indicating an image; a display control means for making the display means display an input screen for inputting a sense of use; an operation means for accepting operation from a user; and a memory means for accumulating, taking the user having inputted a sense of use to the operation means in a state that the input screen is being indicated as a trigger, the sense of use having been inputted and environmental information indicating an information processing environment at the time of inputting the user's sense of use.

Abstract: An imaging device includes an imaging unit that is provided at a case body and images an object; an operation input unit utilized to input an imaging operation; a first instruction unit that instructs the imaging unit to execute the imaging when the imaging operation is input; a second instruction unit that instructs, based on a trigger other than the imaging operation, the imaging unit to execute the imaging; and a control unit that performs, based on a state of the case body, a control to invalidate any one of the instruction by the first instruction unit and the instruction by the second instruction unit.

Abstract: Setting of security for communication is automatically changed for each application that is started up. An electronic device includes a communication unit which communicates with another electronic device, a storage unit which stores setting information of security for communication corresponding to each application, an execution control unit which starts up and executes one application among a plurality of applications used to communicate with the other electronic device and recruit a participant of a community, and a security control unit which reads the setting information corresponding to the application which has been started up from the storage unit and controls security for communication using the communication unit based on the read setting information when the execution control unit starts up the application.

Abstract: An authenticator (11) of a mobile terminal (1) determines whether or not network identification information acquired from a PC terminal (4) matches network specifying information stored in a memory (13). If it is determined that these are matched, a selector (12) selects a client appliance that reproduces or executes the content stored in the memory (13). A communicator (14) transmits the content to the selected client appliance. An authenticator (41) of the PC terminal (4) determines whether or not the server identification information acquired from the mobile terminal (1) matches server specifying information stored in a memory (43). If it is determined that these are matched, an acquirer (42) acquires content that is transmitted to the PC terminal. A player (44) reproduces the content and outputs to a display (45). In a similar manner, an audio instrument (5) and a television (6) also acquire and reproduce the content that is transmitted to the audio instrument (5) and television (6).
