20120155658 | CONTENT REPRODUCTION DEVICE AND METHOD, AND PROGRAM - A content reproduction device including: a microphone that collects noise in the surroundings of a casing; a feature amount extractor that extracts a plurality of feature amounts; a distance calculator that calculates an intervector distance between the extracted feature amount vector and a feature amount vector with the same dimensions which is set in advance as a feature amount of a waveform of a music signal; a determinator that determines whether or not music is included in the sounds collected by the microphone; a processor that processes the signal of the sounds collected by the microphone to change the volume or frequency characteristics of the sounds collected by the microphone; and an adder that adds and outputs the signal of the sounds collected by the microphone and the signal of sounds of reproduced content. | 06-21-2012 |
20140318348 | SOUND PROCESSING DEVICE, SOUND PROCESSING METHOD, PROGRAM, RECORDING MEDIUM, SERVER DEVICE, SOUND REPRODUCING DEVICE, AND SOUND PROCESSING SYSTEM - To preferably identify a piece of music corresponding to an input sound signal. Continuous input sound signals are converted into a predetermined characteristic amount sequence. A checking process of the characteristic amount sequence against music information is sequentially executed when a predetermined quantity of the characteristic amount sequence is accumulated and a piece of music having a matching degree greater than a threshold value is conclusively identified. In this case, since the conversion of the continuous input sound signals into a predetermined characteristic amount sequence and the execution of the checking process of the characteristic amount sequence against music information are executed in parallel, a music identification having a great real-time ability can be performed. | 10-30-2014 |
20140337019 | MUSIC SIGNAL PROCESSING APPARATUS AND METHOD, AND PROGRAM - A music signal processing apparatus includes a frequency spectrum transform unit, a filter, a frequency feature amount generation unit, and a melody feature amount sequence acquisition unit. The frequency spectrum transform unit is configured to transform a music signal into a frequency spectrum, the music signal being a signal of a musical piece containing a part with a melody. The filter is configured to remove a steep peak of the frequency spectrum. The frequency feature amount generation unit is configured to generate, from a signal output from the filter, a frequency feature amount in which a fundamental frequency component of the part is emphasized. The melody feature amount sequence acquisition unit is configured to acquire, based on the frequency feature amount, a melody feature amount sequence that specifies a fundamental frequency of the part at each time. | 11-13-2014 |

20110289589 | UNAUTHORIZED OPERATION DETECTION SYSTEM AND UNAUTHORIZED OPERATION DETECTION METHOD - The content of operations is identified and an alert is generated to an operation having a high risk of information leakage. | 11-24-2011 |
20110320508 | COMPUTER SYSTEM MANAGEMENT METHOD AND CLIENT COMPUTER - The present invention efficiently displays in a tree structure form a file operation history. A file storage identifier, an operation identifier, and a count are stored as additional meta-information in an alternate data stream with respect to each file stored in a client terminal file system. The operation identifier manages a number of operations (operation generations). The count manages copy frequencies. This meta-information is also sent to a management apparatus, and used for displaying the file operation history in a tree structure form. | 12-29-2011 |
20110321170 | FRAUDULENT MANIPULATION DETECTION METHOD AND COMPUTER FOR DETECTING FRAUDULENT MANIPULATION - A client computer detects a user operation for transmitting data to a server or a storage device, determines whether the detected user operation is a fraudulent manipulation, and, if the determination is a positive result, performs security processing which is processing related to security of data to be transmitted. If the data is data within a group to which the user belongs and a destination of the data is a server or a storage device outside the group, the determination is a positive result. | 12-29-2011 |
20120215908 | METHOD AND SYSTEM FOR DETECTING IMPROPER OPERATION AND COMPUTER-READABLE NON-TRANSITORY STORAGE MEDIUM - An embodiment of this invention detects an improper operation to a file in a computer of a monitoring target in a computer system including a plurality of computers connected via a network. The monitoring target computer receives a file. The computer receives acquisition source information on the file transmitted from a different computer. The computer refers to information on improper operation requirements to determine whether transmission of the file meets the improper operation requirements or not, based on a combination of the acquisition source of the file indicated by the acquisition source information and a transmission destination of the file and if the improper operation requirements are met, it determines that the transmission of the file is an improper operation. | 08-23-2012 |
