Adobe has a new tool that makes it easier for creatives to be reliably credited for their work, even if somebody takes a screenshot of it and reposts it across the web. The Content Authenticity web app launching in public beta today allows invisible, tamper-resistant metadata to be embedded into images and photographs to help identify who owns them.
The Content Authenticity web app is “currently free” while in beta, according to Adobe, though the company hasn’t mentioned if this will change when it becomes generally available. All you need is an Adobe account (which doesn’t require you to have an active Creative Cloud subscription).
Any images you want to apply Content Credentials to don’t need to have been edited or created using one of Adobe’s other apps.
Only JPEG and PNG files are supported for now, but Adobe says that support for larger files and additional media, including video and audio, is “coming soon.”
