摘要:
A data providing system for distributing content data from a data providing apparatus to a data processing apparatus and managing said data providing apparatus and said processing apparatus by a management apparatus. In the system, the management apparatus is configured to provide a key file in which is stored content key data and usage control policy data indicating a content of rights, including permission conditions of the content data. At least a part of said key file is encrypted. The data providing apparatus is configured to provide the content data encrypted by using the content key data stored in the key file. The data processing apparatus is configured to decrypt the key file to obtain the content key data from the key file and determine handling of the content data based on the usage control policy data stored in the key file.
摘要:
A content provider 101 distributes a secure container 104 storing content data encrypted using content key data, content key data encrypted using distribution key data, and encrypted usage control policy data indicating the handling of the content data to a SAM 1051 of a user home network 103 etc. The SAM 1051, etc. decrypts the content data and usage control policy data stored in the secure container 104 and determines the purchase mode and usage mode and other handling of the content data based on said decrypted usage control policy data.
摘要:
A SAM receives a secure container in which content data encrypted with content key data, the encrypted content key data, and UCP data designating a handling policy of the content data are stored, and determines at least one of the purchase mode and the usage mode of the content data based on the UCP data. The SAM serves as a slave for a host CPU, and is also provided with a common memory shared with the host CPU.

摘要:
A contents provider stores contents data in a container in a format which can only be decoded with a key distributed from an EMD service center, and transmits the container to a service provider. The service provider adds pricing information and the like and distributes this to a user home network. The user home network pays charges to the EMD service center based on the pricing information, receives the key, and decodes the contents data. Information regarding the number of times which copying is permitted is contained in the secure container, and the number of times permitted is increased each time charges are paid, thereby enabling copying to other media and the like. It is impossible to make copies from a container simply copied, or in cases where in the number of permitted times of copies has been used up. Thus, contents data can be distributed in a format wherein copying of contents data can be controlled including the number of copies made.

To provide a data providing system able to protect the interests of interested parties of a data providing apparatus. The content provider 101 distributes a secure container 104 storing content data encrypted using content key data, content key data encrypted using distribution key data, and encrypted usage control policy data showing handling of the content data to a SAM 1051 of a user home network 103. The SAM 1051 etc. decrypts the content key data and usage control policy data stored in the secure container 104 and determines the handling such as the purchase form and usage form of the content data based on the decrypted usage control policy data.
