Protect Content

Stake a public, tamper-evident claim that this piece of content existed at this moment, signed by your key — without ever uploading the content itself. Drop an image and Parable builds an Aegis Provenance Capsule on-device (SHA3-384 + PDQ + DINOv2 semantic descriptor + tiled Merkle fingerprints), signs it with your ML-DSA-65 chain key, and registers only the capsule on the Aegis fabric. Your image never leaves the device.

The capsule is one-way: it cannot be used to reconstitute the original image — that's mathematically not possible. It only lets anyone, anywhere, prove (or disprove) that a piece of content matches something you registered.

How Notes uses this: when you tick Protect with Aegis Provenance on a note, Parable builds a capsule of the note's contents (and attachments) before they are encrypted under your per-note key and stored on your Veritas chain. The encrypted note stays private. The public capsule lets the world verify authorship and timestamp. Anyone who suspects a misuse of your work — even without ever knowing your name — can drop the suspect copy into Detect and see, through any subterfuge, whether it matches your registered fingerprint.
