摘要： Methods and systems for enhancing the security of data during input and output on a client computer system are provided to prevent attempts by unauthorized code to access, intercept, and/or modify data. Example embodiments provide a plurality of obfuscation techniques and security enhanced drivers that use these obfuscation techniques to prohibit unauthorized viewing/receiving of valid data. When the drivers are used together with the various obfuscation techniques, the security enhanced drivers provide mechanisms for “scheduling” the content of the storage areas used to store the data so that valid data is not available to unauthorized recipients. When unauthorized recipients attempt to access the “data,” they perceive or receive obfuscated data. The obfuscation techniques described include “copy-in,” “replace and restore,” and “in-place replacement” de-obfuscation/re-obfuscation techniques. In one embodiment, a security enhanced display driver, a security enhanced mouse driver, a security enhanced keyboard driver, and a security enhanced audio driver are provided. To complement the security enhancements, the methods and systems also provide for a watchdog mechanism to ensure that the driver is functioning as it should be and various user interface techniques for denoting security on a display device.

摘要： Methods and systems for enhancing the storage and display of video data and other digital content in a set-top box or other television environment so that such data is securely stored and displayed are provided. Example embodiments provide an enhanced display controller (EDC) that executes in an electronic device, such as a set-top box, to provide secure storage and playback of streamed digital content. The EDC creates or identifies a secure storage location and stores the data stream in that secure location in a secure manner, thereby minimizing unauthorized access. In addition, the EDC supports the secure display of the data stream using standard (or proprietary) encryption techniques, and/or obfuscation techniques. The EDC also optionally supports various requirements for complying with the usage limitations typically associated with DRM data content. In one embodiment, the enhanced display controller is a modified set-top display (device) driver that includes a VBI decoder, mechanisms (e.g., code) for securely storing and retrieving digital content, a display obfuscation/encryption mechanism, and a secure data repository. Methods and systems for displaying dynamic, floating graphics using an EDC are also provided. These graphics may be used to as interfaces to invoke the secure storage and playback mechanisms of the EDC and to navigate through display spaces presented on the television display.
摘要翻译：提供了用于增强在机顶盒或其他电视环境中的视频数据和其他数字内容的存储和显示的方法和系统，使得这些数据被安全地存储和显示。示例性实施例提供了在电子设备（例如机顶盒）中执行的增强型显示控制器（EDC），以提供流式数字内容的安全存储和回放。 EDC创建或识别安全存储位置，并以安全的方式将数据流存储在该安全位置，从而最小化未经授权的访问。此外，EDC使用标准（或专有）加密技术和/或混淆技术来支持数据流的安全显示。 EDC还可以选择性地支持符合通常与DRM数据内容相关联的使用限制的各种要求。在一个实施例中，增强型显示控制器是修改的机顶显示器（device）驱动器，其包括VBI解码器，用于安全地存储和检索数字内容的机制（例如代码），显示混淆/加密机制和安全数据存储库还提供了使用EDC显示动态，浮动图形的方法和系统。这些图形可以用作接口以调用EDC的安全存储和回放机制，并且通过在电视显示器上呈现的显示空间进行导航。

摘要： A computer display controller arbitrates between multiple environments in a computer system to apportion display space between the multiple environments. The display controller may be implemented in hardware, firmware, or software, and determines display space allocation based on requests or requirements of each of the environments. If only one environment is active, the display controller may allocate the entire display space to the first environment. When a second environment is activated, display parameters may be dynamically provided to the display controller or previously provided to the display controller for storage and subsequent use. The display controller apportions the total displayable area to accommodate both environments and if necessary alters the display parameters of the first environment to accommodate the display needs of the second environment The process may be extended to additional environments and may operate satisfactorily with computer systems having multiple displays. The display controller may allocate the entire display space to a particular environment, or only a portion of the display space for a particular environment on a single or multiple display device system.
