    • A digital rights management system permits an application owner to cause code to be injected into the application's run-time instruction stream so as to restrict execution of that application to specific hardware platforms. In a first phase, an authorizing entity (e.g., an application owner or platform manufacturer) authorizes one or more applications to execute on a given hardware platform. Later, during application run-time, code is injected that performs periodic checks to determine if the application continues to run on the previously authorized hardware platform. If a periodic check fails, at least part of the application's execution string is terminated—effectively rendering the application non-usable. The periodic check is transparent to the user and difficult to circumvent.
    • 数字版权管理系统允许应用所有者将代码注入到应用的运行时指令流中,以便将该应用的执行限制到特定的硬件平台。 在第一阶段,授权实体(例如,应用所有者或平台制造商)授权一个或多个应用在给定硬件平台上执行。 稍后,在应用程序运行期间,注入代码,执行定期检查以确定应用程序是否继续在先前授权的硬件平台上运行。 如果定期检查失败,至少部分应用程序的执行字符串将被终止 - 有效地使应用程序无法使用。 定期检查对用户是透明的,难以规避。
