摘要: The memory device contains control structures that allow media content to be stored securely and distributed in a manner envisioned by the content owner, or service providers involved in the distribution. A wide variety of different avenues become available for distributing media content using such memory devices, such as where the devices contain one or more of the following: abridged preview media content, encrypted unabridged media content, prepaid content, rights and/or rules governing access to such content. The memory device has a type of control structures that enable a service provider (who can also be the content owner) to create a secure environment for media content distribution where end users and terminals register with the service provider, and gain access to the content in a manner controlled by the service provider. The various components to be loaded (e.g. abridged preview media content, encrypted unabridged media content, prepaid content, rights and/or rules governing access to such content) may be generated and loaded in a secure and efficient manner.

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.
摘要翻译: 访问内容的方法包括在主机设备上安装用于安全可移动存储设备的文件系统过滤器。 挑战从文件系统过滤器发送到主机设备上的软件实体,并且响应于挑战在文件系统过滤器处接收软件实体响应。 文件系统过滤器响应在文件系统过滤器中使用挑战计算,并且如果软件实体响应与文件系统过滤器响应匹配,则提供对安全可移动存储设备上的第一内容的访问。
