PROBLEM TO BE SOLVED: To provide a powerful rights management technique enabling future evolution of technical capabilities and business models. SOLUTION: The rights management arrangement for storage media provides adequate copy protection in an inexpensive mass-produceable, low-capability platform and also provides enhanced, more flexible security techniques and methods when the same media are used with platforms having higher security capabilities. Cryptographically strong security is provided by encrypting at least some of the information carried by the media and enabling decryption based on the control set and/or other limitations. A secure "software container" can be used to protectively encapsulate various digital property content and control object information. Cooperative rights management may also be provided, where plural networked rights management arrangements collectively control a rights management event on one or more of such arrangements.

PROBLEM TO BE SOLVED: To provide a method for driving a DVD device with respect to an information protection scheme using an encryption generation technique. SOLUTION: The method for driving the DVD device comprising a device for reading-out information from a removable DVD disk, includes: a step of supplying the removable DVD disk, wherein the removable DVD disk includes an encryption key block and information for the encryption, and the encryption key block includes a first key and second key; a step of accessing a third key for using it to decode at least part of the encryption key block; a step of using the first key for decoding a first part of the information for the encryption; a step of using at least part of the first part of the information for the encryption being decoded; a step of using the second key for decoding a second part of the information for the encryption; and a step of using at least part of the second part of the information for the encryption being decoded.

PROBLEM TO BE SOLVED: To provide a method including management of copies of managed information. SOLUTION: The method, apparatus and system provides a method including reading out of information whose use is managed from DVDs (optical digital video disks), obtaining of digital discrimination information from DVDs or another storage media, and also obtaining of control information for managing use of at least one of the managed information. It also provides a method including obtaining of at least a part of the control information from DVDs and obtaining of at least another part of the control information from a different storage medium through network connection, and managing of making of copy of the managed information using the control information, and also including that making of copies includes inserting at least a part of the digital discrimination information into at least one copy or associating them.

PROBLEM TO BE SOLVED: To provide a device including a means for managing at least one aspect of access and its use with respect to managed information read from a DVD. SOLUTION: The device is configured to include elements of processor or a controller, a device for reading information from a DVD, a means for carrying out selection between a first set of control information stored in the DVD and a second set of control information wherein the second set of control information is different from the first set of control information in at least one point, and the selection is based upon presence or absence of specified identification information in the device, and a means for using the selected set of control information for managing at least one aspect of access or its use with respect to the managed information read from the DVD.

摘要:
PROBLEM TO BE SOLVED: To provide a comprehensive control, rights management and/or identification solution that remains compatible, where possible, with existing industry standards for limited function copy protection and for encryption. SOLUTION: A method of operating a DVD device including an arrangement for reading information from a removable DVD and a communications port includes the steps of: supplying a removable DVD, the removable DVD including a first information portion, a second information portion and rights management information; using the DVD reading arrangement to read the first information portion from the DVD and output the information to an output device; the DVD device user's selecting an option for permitting the second, encrypted information portion to be read; the selection starting the use of the rights management information; an external device supplying information through the communications port; the rights management information using the supplied information in the process of decrypting the second information portion; and outputting the decrypted second information portion to the output device.

PROBLEM TO BE SOLVED: To provide a technique using cryptography for information protection using cryptography, more specifically, management of rights for information stored on a mobile medium which is an optical medium such as a DVD. SOLUTION: The technique includes: a stage of reading encoded managed contents out of DVD; and a stage of using information stored on the DVD to manage at least one mode among access to the managed contents or uses thereof, the stage partially including of deciding whether a computer device includes a function specified by the information stored on the DVD and allowing 1st use of the managed contents when the specified function is available or inhibiting the 1st use when not.
