Summary

The Content Authenticity Initiative (CAI) is an industry consortium founded in 2019 by Adobe, The New York Times, and Twitter to promote cryptographically secured provenance metadata standards for digital content. The related Coalition for Content Provenance and Authenticity (C2PA) develops the open technical standard (Content Credentials) that embeds verifiable information about a file's origin, editing history, and publisher to help combat disinformation and synthetic media manipulation.

Key Points

  • •CAI was founded in 2019 by Adobe, NYT, and Twitter to promote content provenance standards as a counter to disinformation and AI-generated media.
  • •The C2PA (co-founded 2021 with ARM, BBC, Intel, Microsoft) develops the royalty-free technical standard for provenance metadata embedded in digital files.
  • •Content Credentials metadata can include publisher identity, recording device, location, timestamps, and editing steps, secured via cryptographic hash functions.
  • •The standard applies to photos, videos, audio, and text files, providing a verifiable 'chain of custody' for digital content.
  • •This infrastructure is increasingly relevant to AI safety as a mechanism for labeling AI-generated content and maintaining trust in information ecosystems.

 Community that promotes the Content Credentials (C2PA) standard 
 The Content Authenticity Initiative ( CAI ) is an association founded in November 2019 by Adobe , The New York Times and Twitter . [ 1 ] [ 2 ] [ 3 ] The CAI promotes an industry standard for provenance metadata (known as Content Credentials [ 4 ] ) defined by the Coalition for Content Provenance and Authenticity ( C2PA ). The CAI cites curbing disinformation as one motivation for its activities. [ 5 ] [ 6 ] [ 7 ] [ 8 ] 

 
 Coalition for Content Provenance and Authenticity

 [ edit ] 
 Together with Arm , BBC , Intel , Microsoft and Truepic, Adobe co-founded the non-profit Coalition for Content Provenance and Authenticity ( C2PA ) in February 2021. The C2PA is tasked with the formulation of an open, royalty-free technical standard that serves as a basis for the C2PA member's efforts against disinformation. While the C2PA's work applies to the technical aspects of implementing a provenance metadata standard, the CAI sees its task as the dissemination and promotion of the standard. [ 9 ] 

 Provenance of information

 The structure of C2PA metadata in a file with multiple Manifests generated when the picture was recorded, edited and published 
 The procedures proposed by CAI and C2PA aim to address the widespread occurrence of disinformation [ 10 ] [ 11 ] with a set of additional data (metadata) containing details about the provenance of information displayed on a digital device. Such information can be, for example, a photo, video, sound or text file . The C2PA metadata for this information can include, among other things, the publisher of the information, the device used to record the information, the location and time of the recording or editing steps that altered the information. To mitigate risks that the C2PA metadata might be changed unnoticed, it is secured with hashcodes and certified digital signatures . The same applies to the main information content, such as a picture or a text. A hash code of that data is stored in the C2PA metadata section and then, as part of that metadata, secured with the digital signature. [ 12 ] 

 Securing metadata and the main content with certified signatures helps users to identify the provenance of a file they are currently viewing. If the C2PA metadata names, for example, a certain TV station as the publisher of a file, it is supposed to be very unlikely that the file originated from another source.

 Files with C2PA-compliant metadata that are copied from a publisher's website and then published unaltered on social media (or elsewhere) still retain the provenance information. Users seein
