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： Technology for replacing a first storage unit operatively coupled to a device is provided. Content of the first storage unit is sent to a new storage unit that serves as the replacement of the first storage unit. In one embodiment, the content is first sent to a trusted third-party server and then transferred from the server to the new storage unit. A portion of the content on the new storage unit is adjusted in one embodiment to maintain content security features that were implemented in the first storage unit. The upgrading can be performed under the control of a software entity that is installed on the device. In various embodiments, the first storage unit may be bound to a third storage unit prior to the upgrade process. In such cases, the process can include measures to bind the new storage unit to the third storage unit.

摘要： In order to write data to a storage system accessible with a first and second file system, a manager receives a data write request associated with a file. The manager determines if a function supported by the second file system is needed to complete the write request. If so, the file is opened and extended with the first file system. The file is then opened and written to by the second file system. The file is truncated by the first file system, and closed by both file systems. If the second file system function is not needed, the file is opened, written, and closed by the first file system. In order to read data from a storage system using a function supported by the second file system, the second file system's cached storage system index is updated, and then the file is opened, read, and closed by the second file system.

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： A software entity on a host device attempting to access protected content in a secure memory device must be authenticated using a challenge/response authentication mechanism before the secure file system can be accessed. A file system filter determines whether requested content is protected. If the content is protected, the file system filter provides a challenge to the software entity and generates a file system filter response using the same challenge. The software entity must then send a software entity response using the challenge to the file system filter. If the file system filter determines that the software entity response matches the file system filter response, the software entity is allowed to access the protected content through a secure file system installed on the host device for the memory device.

摘要翻译： 在安全文件系统可访问之前，尝试访问安全存储设备中受保护内容的主机设备上的软件实体必须使用挑战/响应认证机制进行身份验证。 文件系统过滤器确定所请求的内容是否被保护。 如果内容受到保护，则文件系统过滤器会向软件实体提供挑战，并使用相同的挑战生成文件系统过滤器响应。 然后，软件实体必须使用挑战向文件系统过滤器发送软件实体响应。 如果文件系统过滤器确定软件实体响应与文件系统过滤器响应匹配，则允许软件实体通过安装在存储设备的主机设备上的安全文件系统来访问受保护的内容。

摘要： A system and process for improving the appearance of improperly colored and/or improperly exposed images is presented. This involves the use of two novel techniques—namely an automatic color correction technique and an automatic exposure correction technique. The automatic color correction technique takes information from within an image to determine true color characteristics, and improves the color in improperly colored pixels. The automatic exposure correction technique measures the average intensity of all of the pixels and adjusts the entire image pixel by pixel to compensate for over or under exposure. These techniques are stand alone in that each can be applied to an image exclusive of the other, or they can both be applied in any order desired.

摘要翻译： 提出了一种用于改善不正确着色和/或曝光不正确的图像外观的系统和过程。 这涉及使用两种新颖的技术 - 即自动色彩校正技术和自动曝光校正技术。 自动色彩校正技术从图像中获取信息以确定真实的颜色特性，并改善不正确的彩色像素中的颜色。 自动曝光校正技术测量所有像素的平均强度，并逐像素地调整整个图像以补偿曝光或曝光过度。 这些技术是独立的，因为每个可以应用于不同于另一个的图像，或者它们都可以以任何所需的顺序应用。
