Anthropic 上线 Claude 生成文件检测工具

拖放文件，或点击以添加文件。

支持的格式：JPG、PNG、GIF、WEBP、TIFF、HEIC、AVIF、SVG、DNG、JXL、MP4、MOV、AVI、WAV、MP3、M4A、FLAC · 最大 100 MB

Claude 会以两种方式标记它生成的内容：

此工具仅识别内容凭证，它会告诉你 Claude 是否参与了生成该文件。它无法判断 Claude 是否参与了内容创作，也不包含任何用户的身份信息。

当 Claude 生成受支持的文件类型（例如 .png、.jpg 或 .svg）时，它会在文件的元数据中附加一个内容凭证，形式为一条经过加密签名的小注释，说明该文件是使用 Claude 制作或处理的。

这是一个开放的行业标准，称为 C2PA——同样标准被相机制造商和照片编辑软件用来记录图像来源。任何支持 C2PA 的工具都可以读取它。

如果我们找到指向 Claude 的凭证，我们会在这里告诉你。

其他模型提供商也提供类似工具（OpenAI：https://openai.com/research/verify/，Google DeepMind：https://deepmind.google/models/synthid/，Gemini：https://support.google.com/gemini/answer/16722517?hl=en&co=GENIE.Platform%3DAndroid）。

为了检测嵌入文本的水印，我们有一个检测 API，目前根据欧盟法律要求仅向符合条件的组织提供私人预览。

Claude marks content it makes in two ways:

This tool identifies only the content credential, which tells you whether Claude was involved in producing the file. It can't tell whether Claude was involved in creating the content, and it does not include any identifying information about the user.

When Claude produces a supported file type (such as a .png, .jpg, or .svg), it will attach a content credential in the form of a small, cryptographically signed note in the file’s metadata, saying that the file was made or processed with Claude.

This is an open industry standard called C2PA—the same used by camera manufacturers and in photo-editing software to record where an image came from. Any C2PA-aware tool can read it

If we find one that points to Claude, we'll tell you here.

Similar tools are available from other model providers (OpenAI：https://openai.com/research/verify/, Google DeepMind：https://deepmind.google/models/synthid/, Gemini：https://support.google.com/gemini/answer/16722517?hl=en&co=GENIE.Platform%3DAndroid).

To detect watermarks embedded in text we have a Detection API which is currently in private preview to eligible organizations as required under EU law.
