  • Patent number: 9794608
    Abstract: A video transmission method for transmitting, to a video playback device, a video data file group that corresponds to a selected scene from among a plurality of scenes included in video data, the video transmission method includes causing a processor to execute a process including making a length of time corresponding to each data file in a predetermined number of data files shorter than a length of time corresponding to a data file to be transmitted next after the transmission of the predetermined number of video data files, in which the predetermined number of video data files include a video data file to be first transmitted and are sequentially transmitted when sequentially transmitting video data files to the video playback device.

  • Publication number: 20160213296
    Abstract: The system enables a subject himself to decide on a proper remedial measure, without obtaining particular instruction directly from a medical professional, by providing an advice corresponding to a decision criteria of a plurality of classifications (3x4=12) stored in the storage unit, based on a plurality of autonomic nerve function age ranks and a plurality of autonomic nerve function age ranks A screening system for fatigue and stress has a storage unit which, during screening for fatigue and stress, stores master data composed of reference values for each age, a decision unit which decides by comparing a measurement data obtained by electrocardiogram and pulse wave measurement of the subject with the reference value, and outputs a result of decision classified into the plurality of classifications, and a computing unit which receives the decision results, and calculates autonomic nerve function age ranks, wherein the decision means has an autonomic nerve decision unit which decides autonomic nerve strengt

  • Publication number: 20160211002
    Abstract: A video data file generation method for analyzing video data and for generating a video data file group for video data of a specific scene that corresponds to a portion of the video data includes causing a processor to execute a process of generating a video data file corresponding to a beginning portion of the specific scene as a video data file corresponding to a shorter length of time with respect to a video data file corresponding to a portion that is posterior to the beginning portion, and causing the processor to execute a process of storing the generated video data file group in a storage.

  • Patent number: 8266117
    Abstract: In an information system, a web server records web access logs of a client outside of a LAN. A mail server records transmission/reception logs of e-mails. A DB server records access right operation logs. A task application server records DB access log. An administrative server collects logs recorded in the web server, the mail server, the DB server, and the task application server, and operation logs of the client terminals to trace a person and an operation related to information leakage using the collected logs.

  • Publication number: 20040250082
    Abstract: A terminal of a user as an issuer of electronic information calculates a Digest value for a content and sends this Digest value and a key ID of the issuer user to an authentication center server device. The authentication center server device searches a key storage for a secret key corresponding to this key ID, generates a signature value by encrypting the Digest value with this secret key and responds the signature value to the user terminal. The user terminal forms an undersigned content by attaching the received signature value and key ID to signature object electronic information, and issues this content to a recipient. The terminal of the recipient user calculates a Digest value for the content in the undersigned content, and sends this Digest value, the signature value and the attachment key ID to the authentication center server device.
