摘要:
A method and a non-volatile memory apparatus for cloning prevention is provided. The non-volatile memory apparatus includes an Enhanced Media Identification (EMID) area, which is located in a specific area of the non-volatile memory, and stores an EMID for identifying the non-volatile memory; and an EMID encoder for modifying the EMID by a preset operation in conjunction with an arbitrary value.
摘要:
An information transmitting method comprising the steps of: transmitting identification information of a recording medium from at least one terminal section for reproducing a duplicate recording medium duplicated from the recording medium having recorded thereon first digital data related to an encrypted work and second digital data including at least identification information proper to the medium, to a host section via a communication channel; authenticating the transmitted identification information by the host section; requesting the terminal section for accounting; and transmitting data related to a key for decrypting the encryption of the first digital data to the terminal section when the accounting is carried out.
摘要:
A data outputting method for reproducing and outputting digital data including at least work data recorded on a data recording medium and identification information for carrying out identification proper to the data recording medium recorded on the data recording medium, the method comprising the step of data-converting the reproduced digital data using the identification information, and outputting the resultant data.
摘要:
A record medium on which data on a content which contain an information portion having a data length of one packet and including rewritable information, and another information portion including nonrewritable information, the two information portions each having an identifier for diating the rewritable information portion and the nonrewritable information portion, and which contains additional information including management information and buried dispersedly in a plurality of packets.
摘要:
A method of embedding sound field control factors (SFC factors) into a sound source. The method includes coding sound field factors and sound field information to obtain sound field control factors for the sound source in a binary data type, and the sound field factors represent an acoustic characteristic of the sound source and the sound field information represents an environment under which the sound source is recorded, and watermarking the sound field control factors into the sound source without compressing the sound source. In this method, the SFC factors that represent characteristics of the sound source are embedded into the sound source itself using a digital watermarking technology. Therefore, the SFC factors need not be manually set by a user. In addition, the SFC factors can be reliably transmitted, irrespective of header corruption caused by format conversion and transmission of a compressed sound source.
摘要:
A data recorded medium having a data recorded area where digital data including literary work data on literary works such as a music composition and an image is recorded, wherein identification information for identifying the recorded medium is recorded in an identification information recorded area and judging information representing presence/absence of identification information is recorded in a read-in area. The location of the digital data recorded on a recorded medium is managed by identification information for identifying the recorded medium and hence a wide variety of use such as copyings of literary work data is possible.

The source identification data (Finger Print) is injected into the active picture area of a video signal without disturbing the viewing of the video signal and the data is retrieved by a data reader, called a Fingerprint Reader. The data injection or 'fingerprinting' process consists of dynamically offsetting the video pedestal to carry information which can then be read back from any videotape made from the output of the data-injecting unit. In particular, the fingerprint carries the ID number of the unit used and the current date. The offset lasts for one entire field and has an amplitude of approxmately 0.5 IRE that is, a given field either has the nominal setup or a setup value differing from nominal by 0.5 IRE. The data is repeated every 128 fields in order to provide ample samples for the reader to detect and display the source identification data.
摘要:
A recording medium includes an area for recording data which has been subjected to error correction/coding by a first error correction code. In this area, data of a format decodable by a second error correction code which is different from the first error correction code is mixed/recorded. The data of the format decodable by the second error correction code constitutes at least a part of encryption key data.
