Gemini app 可直接验图：基于 SynthID 判断图片是否由 Google AI 生成或编辑，已累计水印 200 亿+ 内容

导读
Google 在内容透明度上的一步：从今天起，你可以在 Gemini app 里直接验证一张图是否由 Google AI 生成或编辑过，用的是 SynthID——这套数字水印技术会把不可感知的信号嵌进 AI 生成内容里。SynthID 于 2023 年推出，此后已有超过 200 亿条 AI 生成内容被打上水印。随着生成式媒体越来越普遍、保真度越来越高，官方把这作为帮助用户更容易判断内容来历的工具部署出来。
推荐理由
200 亿这个量级加上消费端可直接验，是水印路线少见的实质落地。

How we’re bringing AI image verification to the Gemini app
How we’re bringing AI image verification to the Gemini app
We are increasing content transparency by introducing the ability to verify if an image was generated or edited by Google AI right in the Gemini app.
At Google, we’ve long invested in ways to provide you with helpful context about information you see online. Now, as generative media becomes increasingly prevalent and high-fidelity, we are deploying tools to help you more easily determine whether the content you're interacting with was created or edited using AI.
Starting today, we’re making it easier for everyone to verify if an image was generated with or edited by Google AI right in the Gemini app, using SynthID, our digital watermarking technology that embeds imperceptible signals into AI-generated content.
We introduced SynthID in 2023. Since then, over 20 billion AI-generated pieces of content have been watermarked using SynthID, and we have been testing our SynthID Detector , a verification portal, with journalists and media professionals.
How it works
If you see an image and want to confirm it has been made by Google AI, upload it to the Gemini app and ask a question such as: "Was this created with Google AI?" or “Is this AI-generated?”
Gemini will check for the SynthID watermark and use its own reasoning to return a response that gives you more context about the content you encounter online.
What’s next
This launch builds on our history of providing context about images in Google Search and exploring new research innovations like Backstory from Google DeepMind. Looking ahead, we will continue to invest in more ways to empower you to determine the origin and history of content online. Soon, we’ll expand SynthID verification to support additional formats beyond images, such as video and audio, and bring these capabilities to more surfaces, such as Search.
In addition to our own tools, we are collaborating with industry partners to advance content transparency and authenticity standards across our product ecosystem — including YouTube, Search, Pixel and Photos — through our role on the steering committee of the Coalition for Content Provenance and Authenticity (C2PA) .
As part of this, rolling out this week, images generated by Nano Banana Pro (Gemini 3 Pro Image) in the Gemini app , Vertex AI and Google Ads will have C2PA metadata embedded, providing further transparency into how these images were created. We look forward to expanding this capability to more products and surfaces in the coming months.
Over time, we will also extend our verification approach to support C2PA content credentials, meaning you'll be able to check the original source of content created by models and products that exist outside of Google’s ecosystem.
This work is central to our commitment to bold and responsible AI. We look forward to further contributing to the future of AI transparency.
