我正在寻找一种方法，允许在php网页上使用Flash Player播放mp3文件，但隐藏并保护这些文件免于下载.

i'm looking for a way to allow mp3 files to be streamed using a flash player on a php web page, but to hide and protect these files from download.

将文件嵌入到swf中对于该项目是不可接受的，因为用户会上传许多mp3文件.

embedding the file into the swf is unacceptable for this project, since there will be many mp3 files, uploaded by users.

我已经在 http://www.realworldremixed.com/中实现了这种保护，当我试图弄清楚他们是如何做到的时，即使在IE上附加了嗅探器，我也看不到对mp3文件的引用.任何人都知道我可以实现这样的事情吗?

i have seen this kind of protection implemented in http://www.realworldremixed.com/ , when i tried to figure out how they did it, i didn't see a reference to the mp3 file even with a sniffer attached to IE. anyone knows how i can implement something like this?

推荐答案

请参见萨弗拉斯(Sarfraz)链接的问题以征求若干意见.

See the question Sarfraz linked for several opinions.

您可以通过流媒体来做到这一点，因为对于休闲用户而言，窃取"流媒体内容比下载内容更难.更难，但不难.

You can half do this with streaming, because it's harder for casual users to "steal" streamed content than downloaded content. Harder, but not hard.

您可以尝试使用DRM执行此操作.对于内容所有者而言，DRM是一个非常有吸引力的想法，但是最终，您必须权衡利弊.显然，对您的内容获得某种程度的保护是(对您而言)专业人士"，但同时也要考虑非常大的缺点":DRM对您的用户不方便.它需要基础架构的支持.这根本不是专业内容盗贼甚至是有动机的业余爱好者的全部障碍.您几乎可以轻松找到几乎所有内容的"DRM剥离"副本；一旦一个人遇到了麻烦，他们就会倾向于将其提供给其他人(免费或以一定价格购买).

You can try to do this with DRM. DRM is a very attractive idea to content owners, but ultimately, you have to weigh the pros and cons. Obviously getting some degree of protection for your content is (to you) a "pro," but consider the very large "cons" as well: DRM is inconvenient for your users. It requires infrastructure to support. It's not an impediment at all to professional content thieves or even motivated amateurs. You can pretty easily find "DRM-stripped" copies of nearly all content out there; once one person has gone to the trouble, they tend to make it available to others (either for free or for a price).

同时，您正在使用(浪费?)宝贵的开发时间来尝试防止当今世界无法避免的事情.

Meanwhile, you're using (wasting?) valuable development time trying to prevent something that's not preventable in today's world.

我会说:选择流媒体是因为它提高了门槛，然后接受您的内容 会在未经您同意的情况下被一定比例的用户使用.我断言您可以通过让用户在获得您的同意后 轻松便捷地获取内容来降低该百分比，而DRM与这样做完全相反.

I'd say: Go with streaming because it raises the bar, and then just accept that your content will get taken without your consent by some percentage of users. I assert you can lower that percentage by making it easy and convenient for users to acquire the content with your consent, which DRM is exactly the opposite of doing.
