PRAMA is a cryptographic alibi engine that mathematically proves where you were, when you were there, producing court-admissible evidence that survives hostile legal scrutiny.
The forensic stack we inherited assumes you can spot fakes after the fact. That contract is broken. Three independent failures push the legal and social burden back onto the subject of the lie.
C2PA's signature scope explicitly excludes GPS and timestamps so files can be re-encoded. An attacker can rewrite where and when a verified image was captured while the cryptographic signature stays valid.
Software GPS emulators cost the price of a coffee. Carrier ping logs are subpoena-friendly. Today's defense, "my phone says I was here," collapses the moment opposing counsel reproduces the same coordinates on a Raspberry Pi.
Generative models re-train on every detector. Pixel-level forensics is an arms race with diminishing returns. The only durable answer is to invert the proof: stop arguing about the fake, prove the reality.
PRAMA runs as an invisible background protocol on your phone. Each layer adds a different proof: that the data came from real silicon, from your body, and from a moment in time that can never be rewritten.
A quiet record running in the background
Your phone takes a snapshot whenever something changes. You unlock the screen, your cell tower swaps, your watch logs a heartbeat. No prompts, no timers, just a passive ledger of where you actually were.

Tied to you, on your real device
Each snapshot is signed by Face ID and a private key that only your phone holds, then certified by Apple App Attest or Google Play Integrity. The frame is provably yours, from a real device, signed by you.

Encrypted on device, by you
Your raw data is encrypted on your phone using a key only you hold. The server only ever sees a sealed blob and a unique fingerprint. The key stays with you, always.

Permanent, public, verifiable
Every few hours your fingerprint is published to a public ledger with a verified timestamp. From that instant the snapshot is mathematically frozen. Anyone with the receipt can verify it independently, years later.

GPS lies. A single radio is forgeable. A ring of independent radios, glued together by a biometrically signed Merkle root, is physically expensive to fake, and trivially cheap to verify.

Court-admissible by construction
Six real people, on the record, across six different attacks: a school deepfake, a wrongful indictment, a staged crash, a falsely accused taxi driver, a livelihood deactivated overnight, a family scammed by an AI-cloned voice. Every card has two faces. The voice. And the receipt that would have changed the outcome.
I hear my daughter screaming upstairs, 'Mom, mom.' I run up the stairs. I say 'What's going on?' She said 'Somebody in school made naked videos of me.' And my heart dropped.
If you're going to take something to trial, wouldn't you have to have something better than what they presented? You really ruined my life for that. Lost everything I had for that.
I just proceeded to treat it like an accident. I asked them if they were okay. I watched the video multiple times and that's when it hit me. Oh my God, this is probably a setup.
She really has turned my life upside down and I truly wish I can go back to how I used to be, but life is hard at the moment.
I'm the only one with income. It has turned my life upside down.
There is nobody that could convince me that it wasn't her. I know my daughter's cry.
Six different attacks. Six different industries. Same missing piece: proof that what they say happened, actually happened.
PRAMA is that proof, captured before the attack.Five exhibits. Nineteen questions. The same answers PRAMA gives any judge, lawyer, or opposing party who walks into the room.
No. Your location data is encrypted on your device before it ever leaves your phone. Our servers store only encrypted data that we mathematically cannot read. Not now. Not ever.
The first wave is invite-only and capped at 500 devices. Tell us who you are and where you operate. We route invites jurisdictionally based on legal-admissibility maturity.
