SynthID is an AI-generated image watermarking and recognition tool developed in collaboration by Google Cloud and Google DeepMind. The tool embeds digital watermarks into image pixels, making them invisible to the human eye but detectable for identification. SynthID can help users identify AI-generated images and prevent the spread of misinformation. It utilizes two deep learning models for watermarking and recognition, ensuring watermark detectability even under various image manipulations. While not perfect, SynthID empowers users to utilize AI-generated content responsibly.
