Brief

News from Google claims every Nano Banana image in Google Earth carries a SynthID digital watermark that users can verify via the Gemini app or Google Lens and that Google blocks harmful image generation and updates protections. Independent tests highlighted by @henkvaness (shared by @talhagin) found SynthID covered less than 25% of tested images, limiting whole-image verification.

Why it matters

NewsFromGoogle (tweet 2026-07-31) states every image created with Nano Banana in Google Earth includes a SynthID digital watermark and can be checked with the Gemini app or Google Lens; Google also says it prevents image creation on harmful topics and is updating protections.

Key details

  • Community testing highlighted by @henkvaness and shared by @talhagin found SynthID only watermarked the AI-generated portions in tested Nano Banana images—under 25% of the image—limiting full-image verification as AI-generated (digitaldigging.org report).

We take misinformation seriously – every image created with Nano Banana in Google Earth includes the SynthID digital watermark, so if someone is unsure about an image, they can ask the Gemini app or use Lens in Search to see if the image was AI-generated. In addition, we prevent image creation on harmful topics and are continually updating our protections → policies.google.com/terms/ge…
Community note: Google's SynthID only watermarks AI-generated portions of Nano Banana images in Google Earth (less than 25% in tested examples), not the entire image, limiting full verification as AI-generated. digitaldigging.org/p/googles-synt…
