  • Patent number: 7356511
    Abstract: One embodiment of the present invention provides a system that facilitates marking content during distribution of the content to a client. The system starts by receiving a request for the content from the client at the server and then obtaining a content identifier for the content. Next, the server generates a version identifier that uniquely identifies the version of the content that is sent to the client. Once the version identifier has been generated, the server stores the version identifier in a database along with information to facilitate identification of the requesting client. Finally, the server creates the version of the content by marking the content with the version identifier and delivers the version to the client. Note that the markings on the content facilitate subsequent identification of the client by examining the version of the content.

    Abstract: A configuration for preventing information leakage in content use involving data transfer between different devices and illegal content processing is provided. In a content reproduction or recording process involving data transfer between different devices, such as a drive and a host, a media ID (disc ID) used for a content encryption or decryption process is read from a medium. The drive verifies whether the media ID has been recorded in such a manner as to correspond to a header code set on a correct valid medium. When the medium is confirmed to be a valid medium by the verification, on the drive side, the media ID is encrypted and output to the host. With this configuration outside leakage of the media ID, and a content reproduction or recording process using an invalid medium can be prevented.

  • Patent number: 7334129
    Abstract: There are two different methods of embedding supplemental data, e.g. for watermarking into an encoded signal. I. For an encoder, which needs auxiliary information for encoding (=probability information in this special case), the auxiliary information to encode the supplemental data is derived from data used otherwise in the encoding process. The advantage is that the derived auxiliary data does not have to be stored, so that embedding the supplemental data is economical with respect to the total amount of bits used. II. In the encoding process used for super Audio CD, a set of parameters (e.g. filter coefficients) is used by the encoder, whereby these parameters have to be stored, as they are needed for decoding. To embed supplemental data, at least one of the chosen parameters (e.g. the LSB of the first coefficient) is set to a dedicated value in response to the value of the supplemental data to be embedded. The advantage is that the bit rate will not be affected at all.

  • Patent number: 7324974
    Abstract: A digital data file encryption apparatus and method, where a digital data server identifies the user and supplies an encrypted digital data file to the user in accordance with the identified result. A personal computer decrypts the encrypted digital data file supplied from the digital data server and reproduces the decrypted digital data file or re-encrypts it using an encryption key. The encryption key is generated on the basis of an identification number of a data storage medium or digital data playing device. A digital data playing device stores the re-encrypted digital data file downloaded from the personal computer in the data storage medium and decrypts the stored digital data file using the encryption key to reproduce it. A first internal key is added to the identification number to convert the identification number into the encryption key, which is then encrypted according to an encryption algorithm based on a second internal key.

  • Patent number: 7315621
    Abstract: A characteristic amount is retained and calculated from an entered video signal. Embedment intensity is retained and calculated from the retained characteristic amount. Embedment information is embedded as digital watermarks into the entered video signal in accordance with the retained embedment intensity of the previous frame or field that is located at a position earlier in time than a target image subject to digital watermark embedment. As a result, an output signal of video having the digital watermarks embedded therein is produced. The digital watermarks are embedded into the target image with reference to another image located at a position earlier in time than the target image. Such digital watermark embedment suppresses a delay in output of an output image with reference to an input image.

  • Patent number: 7260219
    Abstract: The invention relates to a method of storing data on a rewritable data storage medium, to a corresponding storage medium, to a corresponding recording apparatus and to a corresponding playback apparatus. Copy-protective measures require that on rewritable storage media some data must be stored which shall not be modifiable or erasable by consumer end products. A practical problem is the storage of large quantities of such data in a fixed data area. Typically the capacity is limited to a few bits. Meanwhile the amount of copy protection data that needs to be stored may well exceed the storage capacity available in the read-only fixed data area. The invention therefore proposes to write the copy protection data as system data in the recordable data area (4), e.g. as part of the formatting of the medium (1).

  • Patent number: 7260848
    Abstract: A method for hardening an extensible firmware framework and system in which the framework is implemented. In accordance with the method, a resource access policy that defines rules to allow or disallow access to designated system resources, such as memory and I/O, is defined. During execution of firmware-based event handlers, event handler code may seek to access a designated system resource. In response thereto, access to the system resource may be determined based on a security status of a firmware-based event handler in consideration of any applicable rules defined by the resource access policy. For example, a resource access policy may allow only secure event handlers to access selected portions of memory, while preventing non-secure event handlers from accessing the same. In this manner, errant and malicious event handlers are prevented from damaging critical resources.

  • Patent number: 7251825
    Abstract: Example embodiments relate to exchanging data between several computers or multimedia units through a public network while guaranteeing at the same time the confidentiality of these data. Specifically, the creation and use of a virtual private network (VPN) is disclosed. The virtual private network (VPN) may have a plurality of units connected to a public network, each unit having a security device which may have a unique number UA1. The method may include generating a right Dn associated to the unique number UAn, by the security device of a unit Un, transferring the right Dn to the security device of at least one second unit Um, encrypting the data sent by unit Un and the description of the Dn right by a encryption data key KS, and receiving the encrypted data by the second unit Um, wherein the encrypted data is presented to the security device of the second unit Um to verify if the right Dn is present, and if the right Dn is present, then decrypting the data by the encryption data key KS.

  • Patent number: 7249106
    Abstract: A contents database 114 memorizes the discriminating information for discriminating contents and the temporal information as to the time of content duplication associated with the discriminating information. A recording program 113 acquires the discriminating information of contents to be duplicated and duplicates the contents in association with the acquired discriminating information and with the temporal information memorized in the contents database 114. This substantially prohibits duplication in large quantities without significantly impairing the interests of a user.

  • Patent number: 7240217
    Abstract: A reprogrammable subscriber terminal of a subscription television service which can have the control program code of its control processor modified by downloading new program code from the headend. The control processor stores a boot program in an internal read only memory. Upon start up and resets, the boot program determines whether the control program should be changed from a command sent from the headend. The command, termed a parameters transactions, includes the number of expected download program code transactions required to complete the control code modification, the memory space areas where the code is to be loaded, and the channel over which the download program code transactions are to be transmitted. The channel is tuned and when the boot program receives all the download program code transactions accurately and stores them, the boot program will cause the control program to be restarted at a selected address of the new or modified control program code which has been downloaded.

  • Patent number: 7236958
    Abstract: An anti-piracy software licensing system associates a license file with a particular software product, so that the license file cannot be used with a separate product. The license is associated with one and only one product by associating an Installer Identifier (IID) with the license file. At installation, a set-up or installation program can be executed to install the software product. The set-up program will generate an IID based on a characteristic of the media and will check the generated IID against the IID stored in a license file on the same media. A match will verify that the license file on the media (i.e., the media license file) was not tampered with prior to installation and that the license file was intended to be used with the software product on the media. However, if there is not a match, then the installation will be terminated. At run-time the locally stored license file will be checked. If the license file is present, execution of the software product will be enabled.

  • Patent number: 7225167
    Abstract: Techniques are disclosed for writing data directly onto a product to record each ownership transfer. As a result, the product itself now carries a traceable, auditable, non-forgeable, non-repudiable proof of ownership (and, optionally, ownership history) that can be used in a variety of ways. This recorded ownership transfer information provides an electronic receipt, which may be used by the present owner to prove his or her ownership. (Optionally, other types of transfers may be recorded in addition to, or instead of, ownership transfers.) A transfer agent or registrar creates a unique transaction identifier to represent the transfer, and preferably creates a cryptographic signature over fields representing the transfer. This information is then recorded in a repository that is external from the product.

  • Patent number: 7224798
    Abstract: The present invention is directed towards providing a partial dual-encrypted stream in a conditional access overlay system. The headend equipment includes an aligner, identifier, and remapper (AIR) device (615) that receives a clear stream and one or two encrypted streams, where the two encrypted streams have been encrypted by two different encryption schemes. The AIR device (615) identifies critical packets associated with the clear stream and subsequently allows two encrypted streams to pass and drops the critical packets of the clear stream. A multiplexer (640) then combines a percentage of the non-critical packets of the clear stream and the critical packets of the two encrypted streams to provide the partial dual-encrypted stream.
