您可以在自己的网络应用程序中运行自己的 reCaptcha 服务吗？
reCaptcha使用的后端是开源的吗？它是一个可以部署在给定容器中的简单 Web 应用程序吗？
谢谢， 莱斯
Is the backend used by reCaptcha open source? Is it a simple web app that can be deployed in a given container?
Thanks,
LES

这是一项网络服务。它由第三方提供。
您可以将其集成到您的应用程序中，但就源代码而言，不行。它的价值不在源代码中，而在提供的图像中。它们不是随机生成的，而是来自 OCR 系统无法处理的那些部分的书籍。因此，通过解决 reCaptcha，人们实际上是在帮助扫描书籍。有人负责扫描过程并提供源源不断的新挑战。很难被击败。
It's a web service. It is supplied by a third party.
You can integrate it into your application, but as far as the source code goes, no. Its value is not in the source code but in the images that are supplied. They're not randomly generated but come from books from those parts an OCR system failed to process. So by solving reCaptcha people are actually helping scan books. Somebody takes care of the scanning process and supplied a constant flow of new challenges. Hard to beat.
在您自己的服务器上运行 reCaptcha 会非常麻烦，因为它需要持续提供图像数据（扫描的书籍）才能工作。而且，这也违背了部分目的，即为了共同利益而将书籍数字化。此外，我认为它甚至不可用。
Running reCaptcha on your own server would be very cumbersome, as it requires a constant supply of image data (scanned books) to work. Also it would kind of beat a part of the purpose, that is digitizing books for the common good. Besides, I don't think it's even available.
