    摘要: One or more rights objects (RO) files may be used for storing RO's preferably in the protected area available only to authenticated users. A RO navigation file is stored preferably in an unprotected public area containing status bits, where each status bit identifies whether a location in a RO file contains a valid RO or not. Preferably, there is a one-to-one correspondence between the location for a RO in a RO file and a location in the RO navigation file for the status bit which identifies whether its corresponding location in the RO file contains a valid RO or not. Whether a particular location in a RO file contains a valid RO or not can be found by checking its corresponding status bit in the RO navigation file.

    摘要: A non-volatile memory interface device contains first, second, and third communication interfaces configured for first, second, and third protocols, respectively. The device also contains a memory controller that selectively communicates between the first and second communication interfaces, and between the first and third communication interfaces. The device also contains a receptacle that can receive a removable non-volatile memory card and electrically connect the card to the second and third communication interfaces. The first communication interface may be a Universal Serial Bus Interface and may be in communicatively coupled to a USB connector. The second communication interface may be an ISO 7816 interface. A communications adapter is an enclosure containing a receptacle that can receive a non-volatile memory card and a USB connector. The USB connector is communicatively coupled with the non-volatile memory card in the receptacle. The receptacle's second communication interface with the non-volatile memory card is disabled.

    摘要: A method of accessing content includes installing a file system filter for a secure removable memory device on a host device. A challenge is sent from the file system filter to a software entity on the host device, and a software entity response is received at the file system filter in response to the challenge. A file system filter response is calculated at the file system filter using the challenge, and access to first content on the secure removable memory device is provided if the software entity response matches the file system filter response.
