Patent number: 7636439Abstract: Data to be encrypted is effectively encrypted by a data delivery system for encrypting the data to be encrypted with a transmitting apparatus and decrypting a cipher thereof with a receiving apparatus. In a configuration for encrypting and decrypting the data to be encrypted by using a random number sequence generated by a random number generating portion for generating the random number sequence uniquely decided from an input parameter, the transmitting apparatus generates the input parameter to perform encryption based on metadata of the data to be encrypted while the receiving apparatus generates the input parameter to perform cipher decryption based on the metadata embedded in the data to be encrypted.Type: GrantFiled: September 9, 2005Date of Patent: December 22, 2009Assignee: Hitachi Kokusai Electric, Inc.Inventors: Sumie Nakabayashi, Kazuhito Yaegashi, Munemitsu Kuwabara, Hirotake Usami

Patent number: 7451473Abstract: A video distribution method and a video distribution system connected to a transmission path such as the Internet. The system has a video signal input unit, an encoder for converting the video signal into a digitally compressed image data, an image accumulation and distribution unit for accumulating and distributing the digitally compressed image data, a notification unit for reading the accumulated images and detecting an image change, an image browsing data converter for reducing the accumulated image, and an information terminal for accessing the images of the image accumulation and distribution unit and the image browsing data converter. The notification unit, upon detection of an image change, records the image change occurrence time. The information terminal acquires the image from the image accumulation and distribution unit or the video browsing data converter based on the change occurrence time information stored in the notification unit.Type: GrantFiled: April 8, 2004Date of Patent: November 11, 2008Assignee: Hitachi Kokusai Electric Inc.Inventors: Tsuyoshi Kawabe, Hirotada Ueda, Kazuhito Yaegashi
