MapSafe: A complete tool for achieving geospatial data sovereignty

on YouTube ↗21m

" summary

MapSafe is a browser-only tool that obfuscates point data with donut masking, or aggregates it with H3 hex-binning, then applies a multi-level client-side encryption scheme that yields one encrypted volume distributable with different passphrase-use limits (examples given: 15x, 10x, 5x). Performance: masking ≈1,000 points/s (spiral privacy check adds time), encryption ≈6 s per MB, decryption ≈0.8 s. Final step notarizes the encrypted-file hash on Ethereum notarization; limits: points only, <100 MB.
