SynthID: A tool for watermarking and identifying AI-generated content

SynthID is a tool developed by Google DeepMind for watermarking and identifying AI-generated content. It generates imperceptible digital watermarks that can be applied to images, videos, audio, and text, with the ability to withstand common editing techniques and ensuring user enjoyment while promoting responsible creation and usage of generative AI.

The text discusses SynthID, a tool developed by Google DeepMind for watermarking and identifying AI-generated content. Watermarking has been used by humans for centuries to verify the origin of content, but one challenge is creating a mark that is hidden from viewers but visible to those seeking it. SynthID addresses this challenge by generating a digital watermark that is imperceptible to humans and can be applied across various Google products to tag AI-generated images, videos, audio, and text.

The key feature of SynthID’s watermark is its ability to withstand common editing techniques such as reordering, trimming, adding noise, compression, cropping, and filters. For images, the watermark can be embedded directly into the pixels, while for videos, it marks every frame. In the case of audio, SynthID converts the signal into a spectrogram, embeds the watermark, and then converts everything back into a waveform. When it comes to text, SynthID analyzes the words to be generated next and adjusts the probability for suitable word choices that do not impact the overall quality and utility of the text.

SynthID ensures that the watermarks are undetectable to users, allowing them to fully enjoy their creations without interruption. The technology is already being used across generative AI in Google consumer products, emphasizing the importance of building safety measures into AI tools from the start. SynthID is just one of the tools being employed to promote responsible creation and usage of generative AI, empowering individuals and organizations to use these tools with caution and accountability. Overall, SynthID serves as a valuable tool in the realm of AI-generated content by providing a robust and invisible watermarking solution.
