Open-source dual-layer document sealing protocol. Maps a 512-bit DSTU 4145-2002 / SHA-256 digest into 24-bit micro-coordinate perturbations across 54 triple intersections of the Sri Yantra, paired with PAdES-B-LTA & RFC 3161 TSP archival signatures.

Could you build this?
Partial Hashing, PDF signing, and timestamping can be assembled from existing libraries, but a credible implementation of a custom watermarking scheme and PAdES-B-LTA/QES compliance needs cryptography and legal-standards expertise to verify correctness and security.
What it would actually take: Implement the pipeline in a language with mature PDF and crypto libraries, combining DSTU 4145 signatures, SHA-256 hashing, a PAdES-B-LTA signer with RFC 3161 timestamp authority integration, and a deterministic mapping from the digest into coordinate perturbations on the document. The novel part is the watermark embedding and its robustness to re-rendering, plus any claim of legal validity, which needs qualified trust service provider integration. This requires a cryptographer for security review and standards expertise for PAdES and eIDAS compliance.
