    摘要: A method and apparatus for protecting digital content stored in a universal serial bus (USB) mass storage (UMS) device from unlimited distribution are provided. According to the method and apparatus, a UMS device generates a random key according to a request from a user and shows the generated random key to the user, and then, by using the random key, registration data is encrypted. Accordingly, only a USB host that registers the UMS device after the user connects the USB host directly to the UMS device, can freely use digital content of the UMS device, and even if encrypted registration data of the UMS is leaked out, unauthorized devices cannot register the UMS device.

    摘要: A method of processing digital content performed by an apparatus for storing digital content. In the method, a hardware regional code extracted from a memory of a content storage device is compared with a firmware regional code extracted from firmware, and the digital content is selectively encrypted and stored according to a corresponding regional code only when the hardware regional code matches the firmware regional code.

    摘要: Provided are a transport stream structure of image data, a transmitting and receiving apparatus and method thereof. A transport stream structure of image data includes a header compressed by a lossless compression algorithm; an additional information field for additional information of image data, the additional information field being generated based on compressing the header by using the lossless compression algorithm; and a payload including the image data. The transport stream structure of the image data, the transmitting and receiving apparatus and method thereof enables inserting the additional information without changing the size of the related art transport stream structure of the image data.

    摘要: Provided is a method of preventing digital content stored in a universal serial bus (USB) mass storage (UMS) device from being distributed without restriction. In the method, registration data is encrypted in order to allow a UMS device to decrypt and use digital content using time information only within a predetermined term of validity. Accordingly, even if encrypted registration data of a UMS device is disclosed, it is possible to make it difficult for unauthorized devices to store the registration data, thereby preventing content of the UMS device from being distributed without restriction.

    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.
