Content Credentials
Digital media metadata specification for provenance and authenticity
From Wikipedia, the free encyclopedia
Content Credentials are cryptographically signed metadata structures, known as C2PA manifests, that provide a verifiable record of a digital asset's provenance and modification history. Defined by the C2PA specifications[1], this architecture establishes a core set of technical assertions, while supporting custom schemas to extend metadata regarding authorship, content intent, and machine-readable usage preferences.
The core C2PA specification is authored and maintained by the Coalition for Content Provenance and Authenticity (C2PA), an industry group composed of major technology firms and media companies. It operates as a project of the Joint Development Foundation (JDF), an affiliate of the Linux Foundation. Parallel promotional initiatives, including sponsored brand campaigns in media outlets,[2] educational outreach,[3] and legislative adoption efforts[4] for the standard, are led by the Content Authenticity Initiative (CAI), a cross-sector coalition established by Adobe.
Adoption
There are two main stakeholders who can implement Content Credentials: producers (softwares and hardwares that produce or modify digital media) and publishers (softwares that show digital media to users).
Producers
Adobe
Adobe is one of the first companies to implement the specification, announcing support in Photoshop in 2021.[5] Content Credentials can be enabled and a history of edits is kept.
Google announced support for Content Credentials on its Pixel 10 phones in August 2025. The Content Credentials are embedded on each picture taken from the Pixel Camera, and modifications done using Google Photos. Information include picture timestamp and a non-identifiable signature that proves it was taken from a Pixel 10. As for Google Photos, a list of AI and non-AI edits are kept.[6]
Nikon
Nikon announced in August 2025 a firmware update for the Z6III that enabled embedding Content Credentials directly into its photos.[7] But only a few days later, a vulnerability was discovered in the software of the camera that allowed a user to combine unauthentic images with authentic photos and still have the resulting image with a valid digital signature. Nikon revoked the certificates.[8]
Media organizations
CBC/Radio-Canada and the BBC both have tested attaching Content Credentials to media they produce or verify.[9][10]
OpenAI
OpenAI embeds Content Credentials on the images and videos it generates that includes that the media was created by AI using their platforms.[11][12]
Sony
In June 2025, Sony announced the release of its Camera Verify system for press photographers and news editors using C2PA digital signatures.[13] Initially, the system will be limited to still images, high‑end cameras, and selected news agencies. Registration with Sony Creators' Cloud is also required.[14]
Publishers
In 2024, LinkedIn started to display the signature issuer from content containing C2PA, and whether it was created by Generative AI.[15]
TikTok
TikTok announced in 2024 that an "AI-generated" label would be applied to videos containing Content Credentials if they were AI-generated[16].
YouTube
In 2024, YouTube started showing to users a label that reads "captured with a camera" on videos that show authentic, unedited videos taken by Content Credentials-compatible cameras.[17]
Licensing
The C2PA specifications[18] are released as an open standard under a royalty-free license.
