The SynthID watermark from Google DeepMind can detect AI-generated images - The Verge (www.theverge.com)

Google has developed a tool called SynthID that can watermark AI-generated images in a way that is imperceptible to humans but detectable by AI. The watermark is embedded in pixel values without noticeably changing the image. SynthID is being launched for use with Google Cloud's image generator to verify original photos. While aimed initially at detecting deepfakes, the tool could also help businesses check AI-generated images used for tasks like product descriptions. Google hopes SynthID may become a web-wide standard but recognizes others are working on detection methods too. The launch marks the start of an arms race as hackers will try to circumvent the system, requiring it to continuously improve. Overall, SynthID is a first step toward greater transparency around AI-generated content online.

How well will the watermark survive resizing and compression? What about sharpening or blurring the image?

If the watermark is robust, then it would be nice if web browsers could flag any AI generated images so long as the watermark detection can be done 100% client side.
