Photos and video you can verify later
Silicon Witness gives every photo and video you capture a digital fingerprint the instant it’s recorded, then keeps the original safe in the cloud. If anyone ever questions the file, you can check whether it has changed.
You probably won’t need it today. If you ever do, you’ll be glad the record exists.
Everyone has a camera. What’s hard is showing, months later, that the file you have is the one you took.
You photograph and film the apartment on move-out day. Every wall, every corner.
The deposit doesn’t come back. The landlord says the scuff in the hallway is new.
You send the photo. The reply: That was taken later. Or edited.
A camera roll can show what you saw. It can’t show the file is still the one you recorded.
Silicon Witness is built for that gap. It seals the file at the moment of capture, so the question “has this been changed?” has an answer you can check.
You do the first step. The app handles the next two. The last one is ready whenever someone asks.
Captured at 2:14:08 PM
Capture
Take a photo or video the way you normally would. Capturing in the app is what matters: the record starts at the moment of capture, not after the file has spent a week on your phone.
Seal
As the file is captured, patented hashing technology calculates a cryptographic fingerprint from the file itself. It’s a short code with one important property: change the file and the code changes too.
Store
The original file and its fingerprint are saved to secure cloud storage, so the record isn’t tied to one phone. Lose it, break it, upgrade it. Your records are still there.
Verify
Compare any copy of the file against the fingerprint on record. If they match, it’s the same file you captured. If they don’t, something about it is different.
This is the hallway photo from move-out day, sealed when it was captured. Edit it below and watch the fingerprint, recalculated from every pixel, live in your browser.

This file matches the original record. It’s identical to the photo sealed at capture.

This demo uses SHA-256, a standard cryptographic hash, to show the principle. Silicon Witness uses its own patented hashing technology.
The file you’re checking is identical, bit for bit, to the file recorded at capture. It hasn’t been edited, cropped, compressed or swapped for another version since it was sealed.
What happened outside the frame, what anyone meant, or whether a scene was arranged before you pressed the shutter. Silicon Witness keeps an honest record of the file. The story around it is still yours to tell.
Powered by patented technology designed to help preserve the integrity of your digital records.
As digital media gets easier to change, knowing whether a file matches the original matters more.
Silicon Witness doesn’t guess whether an image looks real. It tells you whether the file in front of you is the one that was recorded.
You don’t need to be suspicious of anyone. You just need the habit of making a record when the stakes are real.
And the rest: rentals, inventories, job sites, caregiving, handoffs. Anything you’d rather document than argue about.
Sealed and stored
Walk every room slowly. Narrate what you see, open closets and cabinets, and end at the front door with the keys on the counter.
The family’s around the table. The lawyer walks Joe through each page, the witnesses watch him sign, and his niece records the whole thing in Silicon Witness.
Years from now, if anyone questions what that afternoon looked like, the family can show the recording and check that it’s exactly the file captured that day. Not trimmed, not re-edited, not swapped.
A recording doesn’t make a will valid, and it doesn’t replace witnesses, notarization or legal advice. It’s a record of the event, kept beside the formalities that make it official.
Each capture becomes a record: the file, the fingerprint made from it, and the details you’ll want if anyone asks.
The photo or video exactly as it was captured. It’s the reference every later check is compared against.
When you pressed the shutter, recorded by the app at the moment of capture.
Where the record was made, if you’ve allowed location access.
The cryptographic fingerprint calculated from the file at capture. Same file, same fingerprint. Any change, a different one.
Where the original lives: your cloud vault, not just the phone that recorded it.
A running log of the record: when it was captured, stored and checked, and what each check found.
Phones get lost, dropped and traded in. Your records shouldn’t go with them. Silicon Witness keeps each original and its fingerprint in the cloud, organized and ready whenever you need them.
Including the legal ones, because you should know exactly what a record can and can’t do.
Silicon Witness is a camera app for moments that might matter later. Photos and videos you capture in the app get a cryptographic fingerprint the moment they’re recorded, and the original is stored in the cloud, so you can check later whether a file has changed.
When you capture a photo or video, Silicon Witness uses patented hashing technology to calculate a fingerprint from the file’s contents. The same file always produces the same fingerprint. Change the file, even slightly, and the fingerprint comes out different.
Yes. Checking a file compares its fingerprint with the one recorded at capture. A match means the file is identical to the original. No match means something about the file is different from what was recorded.
Any change produces a different fingerprint, including filters, crops and the compression some messaging apps apply when you send a video. That’s how changes are detected. To check a file, use the original from your vault or an exact copy of it.
The original file and its fingerprint are stored in the cloud, so your records aren’t tied to a single phone and you can retrieve them later.
No. Silicon Witness doesn’t judge whether content looks real. It answers a narrower question: is this file the same one that was captured and sealed? As editing and AI tools get better, that question becomes more useful.
Silicon Witness provides technology for documenting and verifying digital records. It does not provide legal advice and can’t guarantee that a particular recording will be admissible or persuasive in any legal proceeding. If you’re dealing with a legal matter, talk to a lawyer about how to use your records.
Yes, you can record a signing like any other moment. The recording documents the event. It doesn’t make a document legally valid, and it doesn’t replace witnesses, notarization or legal advice.
Yes. Records live in your cloud vault, where you can organize them and retrieve the original whenever you need it.
