Danaya vs Content Credentials (C2PA)

Compare media authentication platforms — see why Danaya is the only solution that combines cryptographic sealing and AI deepfake detection.

Content Credentials (C2PA): 内容溯源的开放元数据标准

The Key Difference

Unlike Content Credentials (C2PA), Danaya offers a complete hosted platform with both cryptographic sealing and AI detection — no integration required.

About Content Credentials (C2PA)

Content Credentials是由C2PA联盟(Adobe、Microsoft、Intel、BBC等)开发的开放技术标准。它定义了溯源元数据——如文件创建者、编辑内容以及是否涉及AI——如何通过加密签名直接嵌入图像和视频文件头中。

Content Credentials不是一个可以注册使用的产品。它是相机制造商、软件公司和平台实施的规范。Adobe Photoshop和Lightroom可以将Content Credentials附加到导出的文件中。一些徕卡和尼康相机在拍摄时嵌入它们。Verify网站(contentcredentials.org/verify)允许任何人检查元数据。但是,Content Credentials不包含AI深度伪造检测,不提供托管平台,且要求工作流程中的每个工具都支持该标准才能保持链条完整。

Content Credentials (C2PA): Strengths & Limitations

Strengths

  • 由主要科技公司(Adobe、Microsoft、BBC)支持的开放标准
  • 将溯源元数据直接嵌入文件头
  • 通过contentcredentials.org/verify免费验证
  • 在相机制造商(徕卡、尼康)和编辑工具中不断增长的采用率

Limitations

  • 不是产品——链条中的每个工具都必须实施该标准
  • 无AI深度伪造检测——无法分析媒体是否由AI生成
  • 无托管平台——没有兼容软件就无法上传和封印媒体
  • 在社交媒体或消息应用上分享文件时元数据可能被删除

When to Choose Danaya Over Content Credentials (C2PA)

摄影师从Adobe Lightroom导出附有Content Credentials的图像。元数据显示编辑历史和使用的相机。但当图像在WhatsApp上分享或上传到删除EXIF数据的网站时,Content Credentials就丢失了。没有托管验证页面可以作为后备。使用Danaya,摄影师可以用服务器端存储的SHA-256哈希封印图像。生成PDF证书和公开验证链接——任何人都可以验证真实性,即使文件已被重新压缩或重新分享。Danaya还可以检测传入媒体是否由AI生成或篡改。

What You Get with Danaya

Cryptographic Media Sealing

Capture photos and videos live from your phone camera. Danaya locks GPS coordinates, timestamp, and SHA-256 hash at the moment of capture. Download a PDF certificate of authenticity. Anyone can verify it later — no account needed.

AI Deepfake Detection

Upload any image, video, or audio file. Our AI models detect GAN artifacts, diffusion patterns, face-swaps, voice clones, and audio manipulations. Get a clear verdict with a confidence score — free.
