Identity wallet · Truth proofs
A private identity wallet with verified-human messaging and truth-proof challenges — ask anyone to prove a person, a car, or a place is real. No AI. The real thing.
Features
Selfie + government document via NFC chip read. Notarised by Prson with a cryptographic signature scanners can verify offline — no platform calls home.
Spin up anonymous, personal, or organization identities under a single private wallet. Switch contexts freely — no third party can correlate them.
MLS-based group key agreement. The server moves bytes; it never reads them. Forward secrecy on every conversation.
Each verified value (name, birthdate, email, …) is signed atomically by the company key. Disclose what you want — by default the QR carries only hashes.
Send a signed photo or video request to any wallet. The capture is bound to the prover's identity — perfect for "prove this car, house, or person is real" before you commit. See how →
Identity cards verify locally without a network. Lite mode fits in one scan; full mode carries the complete signature chain.
Truth proofs · Challenges
The web is full of strangers, listings, and generated images that may or may not exist. Prson lets you send a challenge to another wallet — a request for a signed photo or video, captured live in our camera, bound to the prover's identity. No AI photos. No AI videos. No camera roll uploads. You get to see the real thing.
Know who is on the other side of the internet.
Use before meeting someone from a dating app, marketplace, or DM. A live signed video proves a real human — not a stolen selfie, not a deepfake, not an AI-generated avatar.
Buying a used car remotely? Send the challenge before you wire a deposit. The seller can't pull the footage off a listing site — it has to be filmed by them, on their phone, right now.
Rental scams die quickly when the "landlord" is asked for a signed walkthrough video. Either you get a real apartment — or you save the deposit.
Marketplace listings, freelancer hardware claims, insurance checks — anything you'd want to confirm "this specific item, in your hands, right now" works as a challenge.
When a challenge arrives, the camera opens with the challenger's prompt pinned at the top. No camera-roll picker, no upload-from-files button — just the live viewfinder.
As the recording stops, we hash the bytes, sign the hash with the prover's identity key, and embed the challenger's prompt and timestamp into the signature payload. The proof is permanently bound to who filmed it and what they were asked.
Cryptography
Verified properties, truth-proof captures, identity handshakes — every artefact Prson hands out is hashed, signed, and verifiable without our servers. Your phone is the trust root; we just relay opaque bytes.

before it ever leaves the device.
Selective disclosure
Because every verified property is signed atomically, you can reveal a single fact about yourself without handing over the underlying document. Pick a question, send the proof, keep the rest private.
Your full birthdate hash and its signature live in your wallet. The app derives "18+: yes" on-device and signs that answer, so a bartender, gym, or website sees a single signed claim — never your actual date of birth.
Once your passport is read via NFC, the country code lives in your wallet as a signed property. Disclose just the country — not the passport number, expiry, photo, or document image.
The "verified human" signature confirms a real person stood in front of a camera and matched a government document. The selfie itself never leaves your phone — only the verification level travels with the proof.
A display name like "Ana" can be verified as a fragment of your signed legal name, with no other fragment exposed. The app checks that every token in the displayed name maps to a signed name property — nothing more.
Country-of-residence is signed independently of your street address. A landlord or service that just needs "EU resident, yes" gets exactly that — never the full address line.
A verified-email hash proves you once controlled an inbox — enough for "this account is the same as that one" linking, without revealing the address itself.
How it works
A 12-word recovery phrase derives every key. The wallet lives on your device, in hardware-backed secure storage.
Anonymous for sensitive chats, personal for friends, an organization to sign members. Each one has its own public address and stays cryptographically separate.
Scan a passport via NFC, prove an email, send a truth-proof challenge to a stranger. Prson signs the proof — you decide who sees it.
Trust model
Every signature, every hash, every key — generated and stored on your device. The server holds only opaque ciphertext and the public-key fingerprints required to route a message.
Scanners verify Prson's company signature against a published public key — no network round-trip needed to confirm "this identity was notarised at this level on this date."
Hashes by default, raw values only with an explicit toggle. Your wallet id (the cross-identity correlation key) is opt-in too — nobody learns it until you let them.
