GOOGLE'S SYNTHID WATERMARK IS HARD TO BREAK, BUT IT DOESN'T SOLVE AI DISINFORMATION

Summary from the TLDR Design newsletter

Google's SynthID watermark survived 300 rounds of simulated compression and resizing in testing, though cropping combined with heavy compression eventually defeated it. Even so, watermarking can't solve AI disinformation broadly, since fragmented detection systems, usage limits, and unlabeled open-source models leave huge gaps. Experts argue the better long-term strategy is authenticating genuine content via cryptographic metadata like C2PA rather than trying to flag every piece of synthetic media.
