About ContentLens C2PA Validator
Verify the authenticity of content you are browsing on the internet!
With this extension, you can inspect images, audio clips & videos online to detect content that has content credentials (C2PA metadata) which are either embedded and/or added via imperceptible watermarks and verify the validity of their provenance.
Key Features:
- Detect AI-generated content, Deepfakes, voice clones etc.
- Retrace original watermarked content from manipulated versions of the content
- View details of content ownership
- View details of content creation process (base images or audio clips used, tools used, edits made etc.)
- View details of content usage rights (AI training, commercialization, editing etc.)
Please see the attached videos and images for more details. The above features provide you with sufficient data points to determine whether the content you are engaging with is safe , trustworthy, and permissible for consumption to make decisions, train AI models etc.
How-to-use :
You can check for manifests attached to images/audio/video by right-clicking and selecting the Verify Content Credentials option. If a manifest or watermark is present, the extension will validate it and display the results via the Content Credentials "CR" pin icon.
Currently, the extension works on :
- Content that has content credentials with embedded manifests (hard-binding)
- Content with cloud manifests added via ContentLens’ soft-binding technology (imperceptible watermarking)
- In Videos, we currently verify the audio component (only) using ContentLens soft-binding
In future releases, we will support :
- Verification of content without content credentials
- Verification of content with cloud manifests added via C2PA approved soft-binding algorithms
- Video verification (audio + video)
