摘要： Provided are a method and apparatus for controlling transmission of content data. In the method, a communication channel is initially established to transmit the content data, the content data is transmitted through the established communication channel, verification is performed a plurality of times to determine whether the content data is transmitted within an acceptable transmission range, and whether to continue the transmission of the content data is determined according to the verification result. Accordingly, when a client moves to a location outside a predetermined acceptable transmission range in a wireless environment, a server stops transmission of the content data. In addition, content data can be continuously transmitted regardless of interference caused by a temporary obstacle between a server and a client.

摘要： A watermarking apparatus for embedding a watermark in a digital image, an apparatus for extracting watermark information from a watermarked image using a public key having a plurality of secret keys, and an apparatus for identifying whether a watermarked image generated by embedding a watermark in each region using a unit secret key is a copy of contents. The watermarking apparatus includes: a watermark generating unit that divides the digital image into a plurality of regions, assigns predetermined secret keys to each of the divided regions, respectively, and generates a watermark for each of the divided regions using the corresponding secret key; and a watermark embedding unit that generates a watermarked image for the digital image by embedding the watermarks in the corresponding regions, respectively, and combines the watermark-embedded divided regions. Since different kinds of keys are used when watermarking and extracting watermarked information, the watermark can be protected from illegal attacks.

摘要： A digital rights management (DRM) conversion method and apparatus are provided. The DRM conversion method includes: (a) obtaining a first content key for the first content and a second content key for the second content through reciprocal authentication between a DRM conversion apparatus and a DRM conversion server, the DRM conversion apparatus converting the first content into the second content; and (b) converting the first content into the second content wherein the DRM conversion apparatus is disconnected from the DRM conversion server. Accordingly, it is possible to transmit content between devices using different DRM systems even offline with the use of a conversion manager (CM) that performs authentication and DRM conversion operations.

摘要： Provided is a method of preventing digital content from being used despite the presence of copy control information. In the method, a security apparatus capable of restricting use of contents generates a nonce with respect to a storage device and stores the nonce in the storage device and a memory separated from the storage device when content is stored in the storage device; updates the nonces stored in the memory and storage device when movement of the content occurs; and permits use of the content only when the nonce of the storage device, which is stored in the memory, is equal to the nonce stored in the storage device if the content is requested for use, thereby preventing a disk cloning attack.
