    摘要: A method of creating a domain based on public key cryptography includes providing, by a content-providing server, a list of devices requesting content, and selecting, by a user, a device from the list; transmitting, by the server, discrimination information on revoked devices to the device; extracting, by the device having received the discrimination information, a secret value from the discrimination information, preparing a certificate using the extracted secret value, and transmitting device information and the certificate of the device to the server; verifying, by the server, the certificate and creating a domain ID and a domain key using the device information; encrypting, by the server, the domain ID and the domain key using a unique public key of the device and transmitting the encrypted domain ID and domain key to the device; and restoring, by the device, the domain key using a unique secret key of the device.

    摘要: Provided is a method of copying data stored in a first storage medium to a second storage medium. The method includes recording the encrypted data stored in the first storage medium on the second storage medium; reproducing a first content key, which is used to encrypt the encrypted data, using a first drive into which the first storage medium is loaded; encrypting the first content key; sending the encrypted first content key to a second drive into which the second storage medium is loaded; and recording the encrypted first content key on the second storage medium. In this method, encrypted data stored in a first storage medium is sent to a second storage medium via a host without decrypting the encrypted data, thereby preventing the data from being hacked or being accessed by unauthorized users and increasing a speed of copying the encrypted data.

    摘要: A method and apparatus for restricting the use of a disc are provided. In this method, first, lead-in data is read out from a loaded disc. Then, a user key is read out from a lead-in area of the disc. Thereafter, the user key undergoes authentication based on a user key received from a host. The authentication is performed by comparing a random number produced by a disc drive with a decrypted random number obtained by the disc drive decrypting a random number encrypted by the host. Accordingly, the use of the disc by an unauthorized third person is restricted, thus preventing a leakage of personal information and a protection of the copyrights of data.

    摘要: A data recording medium, a recording apparatus thereof, and an apparatus for providing contents having a function of securing personal anonymity similar to a prepaid card. The prepaid card type data recording medium includes a control information area on which is recorded coupon ID information for identifying the data recording medium and representing the authority for recording contents. In addition, marginal capacity information for indicating the maximum downloadable capacity of contents may further be recorded on the control information area. The apparatus for providing contents includes an authentication unit for authenticating personal identification information, and a contents upload unit for uploading predetermined contents to the data recording medium when the authentication is successful in the authentication unit. In addition, the apparatus for providing contents further includes an information DB unit which stores marginal capacity information indicating the marginal capacity of contents to be downloaded to the data recording medium according to the coupon ID information. The authentication unit determines whether to upload the predetermined contents by referring to the information DB. Blueray disc, the next generation DVD, can be used in a mobile phone or PDA as a prepaid card type data recording medium.

The method includes recording the encrypted data stored in the first storage medium on the second storage medium; reproducing a first content key, which is used to encrypt the encrypted data, using a first drive into which the first storage medium is loaded; encrypting the first content key; sending the encrypted first content key to a second drive into which the second storage medium is loaded; and recording the encrypted first content key on the second storage medium. In this method, encrypted data stored in a first storage medium is sent to a second storage medium via a host without decrypting the encrypted data, thereby preventing the data from being hacked or being accessed by unauthorized users and increasing a speed of copying the encrypted data.

    摘要: Provided are a method of recording/reproducing data under control of a domain management system. The method includes extracting, from the write command, domain management information regarding the predetermined domain and contents, and copy control information specifying an extent of copying the contents within the predetermined domain; recording the extracted domain management information on the storage medium; generating a domain-bound flag that is used to determine whether the recording apparatus which records the contents on a storage medium is present in the predetermined domain, based on the extracted copy control information; and recording the domain-bound flag and the contents on the storage medium. Accordingly, it is possible to record contents, recording of which is limited within a predetermined domain, on a storage medium outside a slave under control of a domain management system, while preventing the contents from being reproduced within other domains.

    摘要: Provided are an information storage medium from which a total number of times that data can be reproduced is limited, a method and apparatus for recording data on the information storage medium, and a method and apparatus for reproducing data from the information storage medium. The information storage medium includes a data zone storing user data, and a control information zone storing control information regarding controlling a number of times that the user data can be reproduced. Accordingly, a content provider who provides content such as a movie can create various types of business models by recording content on the aforementioned information storage medium, and selling it at a cheaper price. Further, control information is recorded on the information storage medium or a write once zone of the information storage medium before recording content or user data thereon, thereby preventing the control information from being changed or deleted.
