摘要： A system and method of protecting one or more objects rendered on a display device from being observed by an unwanted viewer. A primary object is rendered on the display device, and a privacy protection object is simultaneously rendered over at least a portion of the primary object. At least a portion of the privacy protection object is rendered with a color saturation value, a transparency value, and a phase delay relative to the primary object such that the portion of the primary object over which the privacy protection object is rendered is visibly obscured to a viewer that is located greater than a predetermined viewing distance from the display device and beyond a predetermined field of view of the display device.

摘要： Methods and apparatuses are provided for dynamic registration of privileged mode hooks in a device that can operate in a privileged mode and a non-privileged mode. A data structure is provided which maps between identifiers and functions. An available slot in the data structure is used to store a pointer associated with a function. The identifier can then be made accessible to non-privileged applications.

摘要： System for invoking a privileged function in a device. The system includes a method that allows an application to invoke a function on a device, wherein the device includes at least two operating modes comprising a privileged mode and a non-privileged mode, and the function executes in the privileged mode. The method includes receiving a request from the application to invoke the function and determining the operating mode of the application. The method also includes invoking the function using an interrupt, if the application is executing in the non-privileged mode, wherein the function is executed within the same task as the application. The method also includes invoking the function directly, if the application is executing in the privileged mode.

摘要： Methods, apparatus, systems, and computer program products for invoking remote process calls and facilitating inter-process communications in a protected memory system employ a kernel that supports remote invocation of objects by a system call. The system call may include an object identifier and a set of pointers to input and output buffers. The kernel locates the specified object in a separate server process domain and awakens a server thread within the server domain to invoke the object. Using provided memory pointers, the kernel can copy input and output data across the protection domains in a single step without the need for copying data into an intermediate buffer. This eliminates the overhead of multiple data copy steps that are required in conventional protected memory systems.
摘要翻译：用于调用远程过程调用和促进受保护存储器系统中的进程间通信的方法，装置，系统和计算机程序产品采用支持通过系统调用远程调用对象的内核。系统调用可以包括对象标识符和一组指向输入和输出缓冲器的指针。内核将指定的对象定位在单独的服务器进程域中，并唤醒服务器域中的服务器线程以调用该对象。使用提供的内存指针，内核可以在单个步骤中跨保护域复制输入和输出数据，而无需将数据复制到中间缓冲区。这消除了常规保护存储器系统中所需的多个数据复制步骤的开销。
