如何阻止图像版权盗窃？
图像防盗有办法吗？我指的不是网站，我想要的是如果 JPEG 被盗，它不能被小偷操纵，只能由所有者使用。
Is there s a way for anti theft images? I'm not referring to web sites, what I want is if a JPEG is stolen it cannot be manipulated by the thief, only can be used by the owner.

这是不可能的，因为 jpeg 无法采用数字版权管理。您可以保护文件本身，但是一旦其他人拥有该文件，他就可以随心所欲地处理它。
This is not possible as jpeg doesn't have a mean to employ digital rights management. You could protect the file itself, but once somebody else has that file, he can do with it as he likes.
如果您在网站上托管图像，那么您可能会遇到有人可以下载并保存它、复制它并分发它的可能性。
有些网站使用水印来标记样本图像，然后知道他们将全尺寸图像出售给谁。如果图像开始分发，这可能会让他们获得一些法律追索权。
但实际上，这几乎是不可能防范的。
希望有帮助！
If you host an image on a website then you're stuck with the possibility that someone can download and save it, duplicate it and distribute it.
Some sites use watermarks to mark sample images and then know who they sell the full size images to. This might allow them some legal recourse if the image starts getting distributed.
In practice though this is almost impossible to protect against.
Hope that helps!
即使您可以对文件本身提出保护方案，如果用户可以显示它，他们只需点击打印屏幕即可获取他们可以使用的文件的副本。除非您完全控制用于查看文件的计算机，否则这是不可能的。
Even if you could come up with a protection scheme on the file itself, if the user can display it they only have to hit print screen to get a copy of the file they can work with. Unless you control the computer used to view the file completely it's not possible.
对于您在可访问的网络服务器上自由发布的内容，实际上没有任何好的方法可以防止“盗窃”或免费重新分发。
There's not really any good ways of preventing "theft" or free redistribution of content which you post freely on an accessible web-server.
