Google 向公众开放 SynthID 检测器，称已有 1800 亿图片和视频带水印
Google says 180 billion images and videos now carry SynthID watermarks as detector goes public
Google 将 SynthID Detector 开放给公众，任何人都可以检测图片、视频或音频是否由 Google 及其合作伙伴的 AI 生成，支持 JPG、PNG、MP4 和 MP3 格式。该工具只能识别带有 SynthID 水印的内容，并非通用 AI 检测器，其他检测系统通常也只验证自家水印。OpenAI、Nvidia 和 Kakao 也在媒体中使用 SynthID，Google 称 Apple 预计很快加入；SynthID 检测已内置于 Google 搜索、Gemini 应用和 Chrome，每天收到 100 万次验证请求，累计带水印图片和视频超过 1800 亿。

Anyone can now check whether an image, video, or audio file was created by Google's AI or its partners. Google has opened its SynthID Detector to the public. The tool spots invisible watermarks embedded in content from models like Gemini, Veo, or Lyria and supports JPG, PNG, MP4, and MP3. SynthID isn't a universal AI detector. It only flags content carrying a SynthID watermark. Other detection systems have the same limitation , typically only verifying their own provider's watermarks.
OpenAI, Nvidia, and Kakao also use SynthID for media. For text detection, OpenAI developed its own system . Apple is expected to join soon, according to Google. SynthID detection is also built into Google Search, the Gemini app, and Chrome, where Google says one million verification requests come in daily. The company claims more than 180 billion watermarked images and videos to date.
