如何保护WebFonts [英] How to protect WebFonts

问题描述

我有一个客户想要在他自己的服务器上托管他的web字体。我有一个字体托管到现在的font.com帐户。我真的知道了 fonts.com协议（第18点）。他们说，你可以在自己的服务器上托管文件，但你必须尽可能保护它们。

我能想到的唯一方法就是通过限制请求在 .htaccess 中带有 HTTP_REFERER 的文件上。

我可以做更多保护这些字体吗？做更多是否有意义，你认为这是一个足够的保护？

我个人不相信技术版本的保护，你可以随时复制你可以看到的东西。但我不希望我的客户陷入法律纠纷。你有这方面的经验吗？

我也对法律方面感兴趣。如果有人可以下载字体并重新使用它，会发生什么？他们的意思是我必须保护字体只从热链接或下载以及？

解决方案

你会发现一些有趣的方法在文章中通过typekit：服务和保护网络上的字体

他们使用像HTTP Referrer检查，base64编码，分段的方法。然而，这些都没有提供完整的保护，一个人同意这篇文章中的声明：

lockquote

事实上，对于出现在浏览器，它必须在网上。如果它在网上，它不能完全保护....我们已经提出了我们自己的一些障碍。我们的目的只是为了防止偶然的滥用，并明确表示从Typekit中获取字体是明确的和有意的行为。

第二需要承担的是，被许可人总是可以不理睬这个协议，这就是为什么像Adobe这样生产出最优秀字体的公司在使用条款中明确规定了使用条款，包括在字体许可页面。

另请参阅字体许可问题在W3 CSS3 webfonts规范中讨论。

I have a client that wants to host his webfonts on his own server. I have a font.com account where the font was hosted until now. I went truth the fonts.com agreement (Point 18.) Where they say, that you can host files on your own server, but you have to protect them as good as possible.

The only way I can think of doing so, is by restricting the requests on those files with HTTP_REFERER in the .htaccess.

Can I do more to protect those fonts? Does it make any sense to make more and do you think that it is a sufficient protection?

I don't personally believe in technical copy protection, you can always copy what you can see somehow. But I don't want my client to get in to legal trouble. Do you have any experience with this?

edit

I'm interested in the legal aspect as well. What can happen, if someone can download the font and reuse it? Do they mean i have to protect the font only from hot-linking or from downloading as well?

解决方案

You will find some interesting methods in the article by typekit : "Serving and Protecting Fonts on the Web"

They use methods like HTTP Referrer checking, base64 encoding, segmenting. However none of these provide complete protection and one has concur with this statement from the article:

The fact is, for something to appear in a browser, it has to be on the web. If it’s on the web, it can’t be completely protected....We’ve put up a few hurdles of our own. Our intent is only to discourage casual misuse and to make it clear that taking fonts from Typekit is an explicit and intentional act.

The second thing to bear is that the licensee can always disregard the agreement, and that is why companies like Adobe which produces one the most excellent fonts states the usage terms including for the web in Font licensing page.
