摘要： One of a plurality of users purchases a PC card in which software is included from a distributor of communication software or a seller of PC cards. This purchaser informs a non-purchaser through a safe channel such as off-line of a key for encryption, a URL of the site from which to download the software and a retrieval induction code. The non-purchaser accesses the distributor of communication software, etc., via a network using the URL, key and retrieval induction code, downloads the software corresponding to the software that the purchaser owns, and executes cipher communications or a competition game with the purchaser. The distributor of software or the seller of PC cards pays the purchaser who satisfies certain conditions based upon the contents registered in the user management database.

摘要： The present invention relates to a contrivance for inserting watermark information into a moving image. The watermark information indicative of the ownership of the copyright of the moving image is inserted into the frames of the moving image at irregular intervals, the frames being of such a number that the watermark information is visually unperceivable in the moving image. In addition, the insertion positions of the watermark information in the frames are determined on the basis of random number values. Besides, restrictive information for the copying of the moving image is inserted together with the watermark information. When the moving image has been brought to a standstill into a static image, the watermark information can be visually perceived with ease, so that illegality such as piracy can be readily exposed. Thus, the present invention can provide a simple and inexpensive scheme for the copyright protection of the moving image.
摘要翻译：本发明涉及将水印信息插入到运动图像中的设计。指示运动图像的版权所有权的水印信息以不规则的间隔被插入到运动图像的帧中，这些帧的数量是水印信息在运动图像中在视觉上不可察觉的数字。此外，水印信息在帧中的插入位置是基于随机数值确定的。此外，用于复制运动图像的限制信息与水印信息一起插入。当运动图像静止成静态图像时，可以容易地视觉上感知水印信息，从而可以容易地暴露盗版等非法性。因此，本发明可以提供用于运动图像的版权保护的简单和便宜的方案。

摘要： A key management unit of a service provider system generates an individual key corresponding to a portable module connected to a service client making an access request and informs an authenticating unit of this individual key. The individual key is stored beforehand also in the portable module. A random-number generator generates a random number, transmits this random number to the portable module and informs the authenticating unit of it. The portable module encrypts the random number with the individual key and sends it back to the service provider system. An encrypting portion of the authenticating unit encrypts the random number with the individual key. A comparator of the authenticating unit compares data encrypted by the encrypting portion with encrypted data transmitted from the portable module and, if the two items of data are coincident with each other, confirms an access request from the portable module.

摘要： An encryption communication system including: a communication center having at least a key information generating unit for generating key generating information used for encryption communication; and a plurality of user computers, each interconnected by a plurality of paths through the communication center, and each having at least an encryption key generating unit and an encryption processing unit. The communication center generates the key generating information Z based on predetermined modulo arithmetic formula. The user computer sends a password PW to the communication center, receives the key generating information therefrom, and generates an encryption key K used between the user computer and another party's computer based on predetermined modulo arithmetic formula. Further, the communication center provides a plurality of modulus numbers to share prime numbers assigned to at least two paths between the user computer and the other party's computer, and between the user computer and another party's computer, so that is possible to reduce the number of prime numbers.

摘要： Disclosed is a voice band splitting scrambler. To simplify the hardware thereof, the apparatus comprises a band splitting unit (11) for splitting an input voice signal into a plurality of band channels, and a scrambled voice signal generating unit (13) for carrying out spectrum-inverting and band-relocating operations on the respective channels to generate a scrambled voice signal. The scrambled voice signal generating unit (13) includes a modulating unit (15) for band-relocating the respective channels by noninverting carriers of inverting carriers set in different bands respectively; and an adding unit (17) for adding the signals of the noninverting channels and the signals of the inverted channels to each other.
