Content Credentials: proving your photos are real
When anyone can generate a photo-realistic image in seconds, a photograph stops being proof of anything on its own. That is a real problem for a business that sells on trust: a jeweller's product shots, a builder's before-and-after pictures, a restaurant's dishes. Content Credentials are the industry's attempt at an answer, and they have just started arriving in ordinary phones.
What they are
Content Credentials are a tamper-evident record attached to an image or video: what device captured it, when, and what has been done to it since — cropped, colour-corrected, edited with AI. The record is cryptographically signed, so changing it without detection is impractical. People often call it a nutrition label for media.
The underlying standard, C2PA, comes from a coalition founded in 2021 that includes Adobe, Microsoft, the BBC, Intel and Arm, and has since grown to include Google, OpenAI and the major camera makers.
Why it is suddenly relevant
For years this lived in professional cameras and newsrooms. That changed in 2025, when Google's Pixel 10 began signing every photo taken with its camera app by default — not only AI-edited ones. Leica, Sony, Nikon and others have credential-capable cameras. Adobe's tools and OpenAI's image generator attach credentials to what they produce, and platforms including LinkedIn display them.
So we are moving into a world where a photo can carry evidence of where it came from. Not every photo will, for a long time. But the ones that do will increasingly be the ones people trust.
What they prove, and what they do not
- They prove history, not truth. A signed photo shows it came from a particular camera at a particular time. It does not prove the scene was not staged.
- A missing credential proves nothing. Most images online have none, because most tools and platforms still strip the data. “No credentials” means unknown, not fake.
- They are easily lost. Screenshots, some messaging apps, and many website image optimisers remove metadata. The chain is only as strong as its weakest step.
What it means for a business that sells with pictures
- Keep your originals. Straight off the camera or phone, untouched, somewhere safe. If a photo is ever disputed — a customer claims it misrepresented the product, or someone copies it — the signed original is your evidence.
- Check what your website does to images. Most sites compress and resize photos for speed, which is correct, and usually strips metadata along the way. If provenance matters in your trade, ask whether your platform can preserve it; some CDNs now can.
- Be open about AI imagery. If you use generated images for backgrounds or illustrations, say so, and never use them to depict the actual product. The credential will often say it anyway — and a customer who discovers it for themselves trusts you less than one you told.
- Real photographs are a competitive advantage. As generated images become common, genuine ones of your real work, premises and people become more persuasive, not less.
Good photography remains the cheapest way to earn trust online — product photography on a small budget shows how to get it without a studio. And if you sell jewellery, where the photo effectively is the product page, this guide goes further.
