    摘要: The present invention was made in order to provide a technology capable of safely ciphering compressed and encoded image data irrespective of lines or media and carrying out a correct decoding operation without any shifts in the frames of ciphered moving pictures. Further, so as to prevent giving any means of encoding from comparison of image ciphered data and so as to generate totally different ciphered image data from the same data compressed images, a processing is executed not on an ECB mode but on such modes as CBC, CFB, OFB or the like. Moreover, as an initial vector, information different for frames included in a header, that is, time information from the start of an image or a frame sequential number, is used. In this way, even if compressed images within adjacent frames are accidentally the same, totally different ciphered data can be obtained.

    摘要: A file protection system for protecting a file which is stored in a storage unit includes a storage position deciding unit for deciding a positional-information corresponding to an area in which information of the file is stored in the storage unit and an encryption unit for encrypting the information of the file in accordance with a predetermined algorithm using at least a part of the positional-information decided by the storage position deciding unit. Information obtained by the encryption unit is stored in the area identified by the positional-information in the storage unit. A file protection system is operable when information of a file which was encrypted as described above is read out from a storage unit. The file protection system includes a decryption unit for decrypting the encrypted information of the file which is read out from an area in the storage unit using information corresponding the area, an extracting unit for extracting the positional-information from information obtained by the decryption unit, and a determination unit for determining whether or not the positional-information extracted by the extracting unit is equal to corresponding positional-information which is at least a part of the information corresponding to the area from which the encrypted information of the file is read out. When the determination unit determines that two pieces of positional-information are not equal to each other, it is determined that the information obtained by the decryption unit does not include correct information of the file.

    摘要: Method for making delivery of products more efficient, and having deliveries made that are convenient for delivery recipients. When a user (delivery recipient 3) purchases a product from a vendor and applies for delivery, a management server 4 accepts a delivery application from a vendor client 1. The management server 4 notifies the delivery recipient client 3 of the application for delivery, and prompts the user to designate delivery terms. For example, a delivery terms designation form is provided on a web page, and the URL for that web page is provided in the application for delivery notification. The delivery recipient client 3 accesses the web page and refers to a list of products to be delivered to him or herself. Moreover, the delivery recipient designates delivery terms when he or she is certain of his or her schedule. A delivery business is notified of these delivery terms.

    摘要: To notify users, in real time, of information that matches a search preference. Preference database 12, register 11, preference setting unit 1, recording unit 13, preferential search unit 14, notification unit 15 and channel display section 2 are provided. Preference database 12 stores, associated with the user, one or more search preferences to search for a channel. Register 11 registers search preferences in preference database 12. Preference setting unit 1 receives the input of search preferences, and sends them to register 11, associated with the user. Recording unit 13 stores the state of each channel. Preferential search unit 14 judges, based on the state of each channel, whether each channel satisfies any search preference. Based on the judgment of preferential search unit 14, notification unit 15 notifies the corresponding user terminal of the channel that meets any search preference of the user. Channel display section 2 outputs the reported contents.
