Abstract: Provided is a technique for accurately estimating a scene even when the number of input signals increases. A scene estimation method includes: when S is the number of scenes and M is the number of input acoustic signals, an acoustic signal encoding step of generating, by a scene estimation device, an integrated acoustic feature amount from an m-th input acoustic signal (m=1, . . . , M) and a position where the m-th input acoustic signal is acquired (hereinafter referred to as an m-th input acoustic signal acquisition position) (m=1, . . . , M); and a scene selection step of selecting, by the scene estimation device, a scene from which M input acoustic signals are acquired from among S scenes, using the integrated acoustic feature amount.

Abstract: An input device for inputting a user operation includes a data-for-authentication holding unit that holds data for authentication regarding one or more registered users, a fingerprint sensor that accepts fingerprint information of a user, and a fingerprint authentication unit that checks the accepted fingerprint information against the data for authentication regarding the one or more registered users. When the fingerprint authentication unit 84 succeeds in biometric authentication, a communication unit transmits a network account of the user to an information processing device. The information processing device includes a user authentication unit that checks the received network account against network accounts of registered users held in a registered user information holding unit.

Abstract: A differencing generator generates difference data between a first data set and a second data set. An encryption unit encrypts data. An electronic signature generator generates the electronic signature of data. A transmission data generator generates transmission data. The encryption unit encrypts the difference data generated by the differencing generator so as to generate encrypted difference data. The transmission data generator generates transmission data containing both the encrypted difference data generated by the encryption unit and the electronic signature of the second data set as generated by the electronic signature generator.

Abstract: There is provided a program for making a computer perform a first procedure for verifying whether an platform guaranteeing that device identification data for identifying a communication device cannot be rewritten by the user is provided in the communication device, a second procedure for verifying whether the device identification data included in a registration request received from the communication device is not yet registered, and a third procedure for registering the device identification data included in the registration request and issuing user identification data to the user when the program determines in the first procedure that the platform is provided and determines in the second procedure that the device identification data is not yet registered.

Abstract: A computer system capable of executing a basic program for providing a program execution environment. The system has a storage device for storing data that is necessary to the basic program during startup, and, for each basic program, configuration data that indicates information relating to data necessary during startup. In the computer system, data relating to the basic program that is to be started is read from the storage device setting, data necessary during startup is acquired from the storage device on the basis of information written in the configuration data, the data necessary during startup is stored in memory space that is in the memory device and that can be accessed from the basic program that is to be started, and a process for starting the designated basic program is executed.
