密码保护的wmv [英] Password protected wmv
问题描述
我们有一个受密码保护的程序，附带一组.wmv视频教程。在应用程序中，通过调用System :: Diagnostics :: Process :: Start（filename） 来播放wmv文件，默认查看器将播放文件。
We have a password protected program that ships with a set of .wmv video tutorials. From within the app the wmv files are played by making a call to System::Diagnostics::Process::Start(filename) and the default viewer will play the file.
为了保护专有信息，我们需要防止在没有安装我们软件的计算机上复制和播放.wmv文件。保护.wmv文件的密码可以解决问题，但是wmv文件不支持密码
保护。
In order to protect proprietary information, we need to prevent the .wmv files from being copied and played on computers that do not have our software installed. Password protecting the .wmv files would solve the problem, but wmv files do not support password protection.
我正在寻找解决此问题的想法和建议。
I am looking for ideas and suggestions to solve this issue.
