Visit website
SealZero lets you prove image and document authenticity using zero-knowledge proofs — fully client-side. You can selectively mask sensitive parts of a document, share the modified version, and provide a cryptographic proof that guarantees authenticity and integrity. No data ever leaves the browser. Proof size is under 11kB. Open-source and built for real-world use.

Hey PH 👋 SealZero started from reading the PETS 2025 paper “VIMz: Private Proofs of Image Manipulation using Folding-based zkSNARKs” by Stefan Dziembowski, Shahriar Ebrahimi, and Parisa Hassanizadeh. I was curious how these ideas could move from theory into something actually usable. Working daily with sensitive HR documents, I know how hard it is to share redacted files while still proving their authenticity. SealZero explores that gap: mask sensitive parts, share the result, and attach a verifiable cryptographic proof — generated fully client-side. Would love your feedback from privacy, security, and dev tooling folks! 🔐✨
