Google 推出改进版 SynthID 检测器并面向全球开放
Google rolls out improved SynthID AI content detector, now available globally
Google 宣布 SynthID 检测器现在支持所有合作方的水印，并上线 SynthID.com 网站供任何人使用。此前外部用户只能通过 Gemini 检测水印，且旧版检测器只识别 Google 自己的 SynthID；SynthID 是嵌入在图像、视频像素和音频波形中的隐形水印，仅 Gemini 就已集成超过 1800 亿张图片和视频以及 24 万年的音频。
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.
