The Content Authenticity Initiative (CAI) aims to increase the reliability and transparency of data existing online by developing industry-wide attribution standards that empower both creators and consumers. Is an Adobe-led community founded in 2019. It is a community created to counter problems such as false alarms and counterfeit information spreading on the Internet, and it is said that more than 750 people from industries such as technology, publishing, human rights activities, journalism belong to it.

In response, the Coalition for Content Provenance and Authenticity (C2PA: Content) is a coalition of organizations set up by major companies in the technology and publishing industries such as Adobe, Microsoft, Sony, and Twitter to develop open standards. (Union for Proof and Authenticity) ”, the Union has announced a specification called“ C2PA ”of the same name as a technical specification for proving media sources and editing history.

In late 2021, CAI will implement a specification called ' content credentials ' that can be used with software such as Photoshop and Stock for users of Creative Cloud, Adobe's paid subscription service. This allows content creators to attach important attribution data to images and present them to consumers.



Adobe has developed a tool to leave historical data using encryption technology, saying that content authentication information should be adopted not only for image data created in Photoshop but also for news, art, social media, etc. Is working on. It is said that Adobe's efforts have been supported by basic principles such as security, privacy, accessibility, interoperability, and openness, and it seems that the tools under development will also comply with these.

By adopting the technical specification that Adobe's tool for adding content authentication information to all media is adopted in a wide variety of fields called C2PA, 'in the near future, on websites, social media platforms, and even metaverses. Even with content credentials, you'll be able to see it, 'said Erin Finnegan, Adobe's community engineer.

The following three 'open source tools for implementing content authentication information' announced by Adobe this time.

1: JavaScript Software Development Kit (JS SDK)
The JS SDK uses content credentials to provide you with what you need to develop a rich browser-based experience. By using the JS SDK, it is possible to display the content credentials on the site or app, and it is also possible to create a link to the service- Verify to confirm the content credentials.

2: C2PA tool
The C2PA tool allows you to create, validate, and search content credentials from the command line. In addition to displaying the content credentials for your site or app, you can write and inspect the content credential data to a file.
