Could you build this?
Partial Client-side encrypted ephemeral file sharing is straightforward, but robust leak tracing via invisible steganographic watermarking across diverse file formats requires specialized forensic engineering.
What it would actually take: The app needs client-side Web Crypto API (AES-GCM) and ephemeral storage (like Cloudflare Workers with KV/R2). The difficult element is the forensic tracking engine: implementing robust digital watermarking (e.g., zero-width character manipulation for text, frequency-domain DCT/DWT steganography for images, and metadata manipulation for PDFs) that withstands re-encoding, screenshots, or copy-pasting to reliably identify the recipient.
