Content Authenticity Initiative

The Content Authenticity Initiative (CAI) is an association founded in November 2019 by Adobe, The New York Times and Twitter.

[5][6][7][8] Together with Arm, BBC, Intel, Microsoft and Truepic, Adobe co-founded the Coalition for Content Provenance and Authenticity (C2PA) in February 2021.

[9] The procedures proposed by CAI and C2PA 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.

Securing metadata and the main content with certified signatures enables users to reliably identify the provenance of a file they are currently viewing.

In addition to the three founding members Adobe, the New York Times and Twitter, these include Arm, BBC, Microsoft, Nikon, Qualcomm and The Washington Post.
