When I saw that DALL-E started adding a tag to its images so people could verify that it’s been generated, I assumed it had to be steganography and didn't read any further.
Nope, it’s just a metadata field in the file 🙃
"It can easily be removed either accidentally or intentionally. For example, most social media platforms today remove metadata from uploaded images, and actions like taking a screenshot can also remove it.”
Want to know when I post new content to my blog? It's a simple as registering for free to an RSS aggregator (Feedly, NewsBlur, Inoreader, …) and adding www.ff00aa.com to your feeds (or www.garoo.net if you want to subscribe to all my topics). We don't need newsletters, and we don't need Twitter; RSS still exists.
