I created a digital watermark for nano banana images that anyone can upload and verify their details using the same image. this makes insurance claims machine readable and authentic because of non hackable nature with aes encryption. This project adds a secondary, tamper-resistant watermark to AI-generated images. The watermark encodes a unique identifier that pairs with existing GenAI watermarks, creating a reliable chain of authenticity. Any system—or chatbot—can decode these markers to verify image origin and integrity. The approach supports real-world use cases like insurance claim validation, fraud detection, and verifying the legitimacy of marketing creatives, without altering the visual quality of the images. It’s a lightweight way to bring trust and traceability to images with generative ai. Images without watermark woudl be useless. with images with watermark two things are validated - synthid (using nature paper code) and the custom watermark to make it work.
