## AI 摘要

Google DeepMind 2023 年推出 SynthID 数字水印，已覆盖图像、视频、音频和文本，累计标记超 1000 亿图像视频及 6 万年音频。用户可在 Google 搜索、Chrome 内 Gemini 及 Gemini App 验证内容，使用超 5000 万次。同时采用 C2PA Content Credentials 标准，可查内容来源与修改历史。已开源文本水印技术，并与 OpenAI、NVIDIA、Apple 等合作推广。

As generative AI tools continue to evolve， we believe it's more important than ever to know what's AI-generated and what isn't. That's why @GoogleDeepMind launched SynthID in 2023-a technology that adds a hidden digital watermark to AI content.

Here's a summary of SynthID's journey and where the provenance technology （the documented history and origin of digital content） is today：

- SynthID watermarking was originally built for images， but now supports video， audio， and text.

- The technology has watermarked over 100 billion images and videos， alongside 60，000 years of audio.

- You can now verify content with SynthID directly in Google Search， Gemini in Chrome， and the @GeminiApp， where it has been utilized over 50 million times.

- We've also adopted C2PA Content Credentials across a growing number of our generative AI tools. This includes the images and videos created within the Gemini app. So now， in addition to the SynthID watermark， you can also see where an image or video originated and how it's been altered.

- We have open-sourced our text watermarking technology， and we are working with companies like @OpenAI， @NVIDIA， and @Apple to apply SynthID to generative media.

Let us know what you think of the tool so far！
