Google 升級 SynthID AI 內容檢測器並向全球開放使用
Google rolls out improved SynthID AI content detector, now available globally
Google 升級 SynthID 檢測器，現已支援所有合作夥伴的水印，並透過 SynthID.com 開放全球用戶檢查 AI 內容。SynthID 是嵌入 AI 生成圖像和影片像素、以及 AI 音訊波形中的隱形信號；用戶現在可直接在網站查驗，毋須再透過 Gemini。
Every piece of AI content from Google's Gemini models has a hidden SynthID label, which makes it very difficult to pass the content off as authentic. SynthID has also gotten buy-in from other major AI players, but actually checking for those invisible watermarks has been a convoluted process. It's going to be a little easier going forward, though. Google has announced that its SynthID detector now supports watermarks from all its partners, and it's available for anyone to use on a new dedicated website.
SynthID is an invisible signal encoded in the pixels of AI-generated images and videos, and in the waveform of AI audio. Google says Gemini alone has integrated SynthID with over 180 billion images and videos, plus 240,000 years of audio. Until now, the only way for those outside of Google's trusted tester program to check for SynthID was to ask Gemini. This is rather clunky, and the model's output could sometimes be confusing when you just wanted a simple "yes" or "no."
Now you can cut Gemini out of the loop. Starting today, you can go to the new SynthID.com website to check a piece of content for an AI watermark. A major limitation of Google's previous detector was that it only checked for Google's version of SynthID. Even though ChatGPT images, for example, have SynthID, they wouldn't be flagged in Google's detector. That's no longer a problem.
