#Vernissage now supports uploads with #C2PA Content Credentials and displays certificate and provenance details. The attachments show the panel for a camera photo and an AI-generated image. Explore the first example: https://vernissage.photos/statuses/7704370278968592687 Here’s hoping this standard becomes more widespread - knowing where an image comes from matters!

Add Content Credentials support (C2PA) by dansup · Pull Request #7943 · pixelfed/pixelfed

Cameras, phones and image generators increasingly embed C2PA Content Credentials in the files they produce. A credential is a signed manifest that records how a file was made, including whether it ...

Once again, a grant application to support #Vernissage has been rejected. This time, #NLnet declined funding for #C2PA photo provenance. I’m genuinely sad and disappointed. #C2PA is an open standard, unlike Apple’s proprietary Reference Image solution. I’ll implement it in Vernissage anyway, but on a much smaller scale than I had hoped. 😔

You've seen the little "cr" badge start showing up on images. Do you know what it actually proves — and what it doesn't? It's not a vibe check. It's a COSE-signed certificate chain sitting inside a JUMBF box in a JPEG's APP11 segment (or a PNG caBX chunk). The signature proves two things and only two: which tool or camera signed the manifest, and that the pixel data hasn't changed since. That's the entire guarantee. The digitalSourceType field inside that manifest is what tells LinkedIn's badge to say "AI-generated" instead of "camera capture" — trainedAlgorithmicMedia vs digitalCapture. LinkedIn reads it. X is rolling out the same read. Where it stops: no manifest, no proof either way. The chain says nothing about who the human behind the tool is, and most images in circulation still carry no manifest at all — that's normal, not suspicious. snapWONDERS validates the full chain on every upload — signature, hash binding, source type — and feeds it into the authenticity score.

Think Twice Before Claiming AI Work as Your Own — What C2PA Content Credentials Prove — Kenneth B. Springer

AI tools increasingly sign what they create, and editing the file rarely erases it. How C2PA content credentials work, who's using them, and where LinkedIn fits in.

Variety | YouTube Will Start Automatically Tagging Videos That Make ‘Significant’ Use of AI, and It’s Making Labels for AI-Generated Content More Prominent by Todd Spangler AI generated summary, Read the full article for complete information. YouTube announced that it will begin automatically labeling videos that make “significant photorealistic” use of AI, moving the AI‑generated‑content tags to a more visible spot—directly beneath the player for long‑form videos and as an overlay on Shorts—while still requiring creators to manually disclose realistic AI use when they wish. The new internal detection system will apply the label if it detects substantial AI‑generated imagery, and the label will remain permanent for content created with YouTube’s own AI tools or that contains C2PA metadata, though creators can adjust their disclosure status in YouTube Studio if they believe a video was flagged incorrectly. YouTube says the labels are purely for viewer transparency and will not affect recommendations or monetization, and they complement the platform’s expanded likeness‑detection program that lets creators manage unauthorized synthetic uses of their appearance.

YouTube is making AI-generated content labels more prominent, and it's going to start automatically applying the labels if it detects that a video includes 'significant photorealistic AI use.'
