    • An improvement relating to the security of an operating system for either a stand alone computer system or for a networked computer system. The operating system provides improved security for programs available on the computer system having different security protocols. The operating system unifies these security protocols for each user based on unique user credentials. The system operates, upon request to start a program procedure by the user, to authenticate the identity of the user based on information unique to that user. Following which, the system generates a user handle associated with the user. The system then notifies each of the security protocols of the user handle associated with the user. The system then generates new user credentials for each of the security protocols. These user credentials are associated with the user handle and then the user handle is mapped to the unique user's credentials for each program procedure. Once this is accomplished, the system invokes an alternate process and tags the process with the user handle. Once a request from the alternate process for access to an object accessed through the server is requested, the system then grants access to the object based on the new user credentials associated with the user handle. The new user credentials are typically based on an association of the user identifier, the user handle, and the unique user credentials from before.
    • 关于独立计算机系统或联网计算机系统的操作系统的安全性的改进。 操作系统为具有不同安全协议的计算机系统上可用的程序提供改进的安全性。 操作系统基于唯一的用户凭据统一了每个用户的这些安全协议。 根据用户启动程序程序的要求,系统根据该用户唯一的信息对用户的身份进行认证。 之后,系统生成与用户相关联的用户句柄。 系统然后通知与用户相关联的用户句柄的每个安全协议。 然后,系统为每个安全协议生成新的用户凭据。 这些用户凭据与用户句柄相关联,然后将用户句柄映射到每个程序过程的唯一用户凭据。 一旦完成,系统将调用一个替代过程,并使用用户句柄标记该过程。 一旦请求来自替代进程的访问通过服务器访问的对象被请求,则系统基于与用户句柄相关联的新的用户凭证来授予对对象的访问。 新的用户凭证通常基于用户标识符,用户句柄和来自之前的唯一用户凭证的关联。

    • In a signal processing environment, voice messages are stored into and read out of a buffer in real time. Since voice messages are being stored and read from the buffer, different sizes and rates of information are being stored therein. Small packets of digitized voice are input to the buffer at a very high rate, while larger packets of data are output from the buffer at a lower rate and can be stored into permanent memory. The buffering of this digitized voice data occurs in real time using a ringed buffer. The transfer of data into and out of the buffer is under the control of a software application running on a host processing system. The producer of the digitized voice data is a signal processing system which converts an input analog voice signal into a compressed digitized signal. The consumer of the buffered digitized voice data is a software application program which removes blocks of multiple data records from the buffer for program execution.
    • 在信号处理环境中,语音消息被实时地存储到缓冲器中并从其中读出。 由于语音消息正在从缓冲器存储和读取,所以存储不同大小和信息速率。 数字化语音的小包以非常高的速率输入到缓冲器,而较大的数据包以较低的速率从缓冲器输出,并且可以被存储到永久存储器中。 该数字化语音数据的缓冲使用振铃缓冲器实时发生。 数据传入和传出缓冲区是在主机处理系统上运行的软件应用程序的控制下进行的。 数字化语音数据的生成器是将输入的模拟语音信号转换为压缩数字化信号的信号处理系统。 缓冲数字化语音数据的消费者是从缓冲器中移除多个数据记录块以用于程序执行的软件应用程序。
