The honest watermark camera.
Verified when it matters, flexible when it doesn't.
From snapshot to verifiable credential in three steps.
Take a photo. Trustamp records the device timestamp, GPS, and a hash of the image — locally, in EXIF metadata. No upload needed.
One tap to "witness" the photo: a tiny hash + timestamp ping to our server (~200 bytes). The photo itself stays on your phone.
Need proof later? Get a share link to a public verification page showing the time, location, and the image's tamper-evident hash. (Full C2PA credential signing + PDF export — coming soon.)
Five things we do differently.
Our server is the clock. Even if your phone's time is wrong (or spoofed), the credential carries a timestamp you can't argue with.
Watermark mode — quick, flexible, no upload, no verification. Credential mode — server-witnessed for proof that holds up. You choose, per shot.
Country, city, and street come from your real GPS and can't be edited. The doorplate or unit number? You can refine that — and every refinement is transparently noted on the credential.
Multiple layers of obfuscation and integrity checks make it hard for anyone to forge a Trustamp credential by reverse-engineering the app.
Today: share a public verification URL
(trustampcamera.com/verify/<id>) for any audience —
it works even on platforms that strip EXIF.
Coming soon: full C2PA / Content Credentials
so you can also verify a photo in Adobe Verify, Chrome, or any C2PA tool —
the open standard backed by Adobe, Microsoft, Sony, Nikon and others.
Pay for verification, not for taking photos.
Just a watermark camera.
Witnessed at capture. Upgrade later.
Final price TBD before launch — early waitlist gets locked-in pricing.
Full credentials. PDF exports. Public verify URL.

Not everyone needs every shot to be proof. We don't either.

Property managers, HVAC techs, surveyors — document every site visit indisputably, with a PDF the client can't dispute.
Photos that hold up. C2PA-signed, server-witnessed, verifiable by any adjuster or lawyer using Adobe Verify.
Honest, head-to-head. We'd rather show you the difference than hide it.
Two big differences. (1) Trustamp is built for the open C2PA standard, so any tool — Adobe Photoshop, Chrome, third-party verifiers — will be able to independently verify your credential (C2PA verification is coming soon; today a public verify link already lets anyone check a photo without our site). Timemark uses a closed system where verification only happens on their website. (2) Trustamp lets you refine GPS at the doorplate level (country/city/street are locked), while Timemark doesn't allow GPS correction at all — a top complaint in their one-star reviews.
When you take a photo, Trustamp sends a small fingerprint (SHA-256 hash) of the image to our server — about 200 bytes, no upload of the image itself. Our server timestamps it. Months later, if you need to upgrade that photo to a full credential, you upload the original, we match the hash, and we can vouch that the photo existed on the original capture date. It's cheap, private, and makes "upgrading old photos to credentials" possible.
Yes — but only in Watermark mode, which gives you full creative control with no verification claim. In Credential mode, the image is content-locked from capture. You can still refine the address text (within the GPS-derived street boundary), and every refinement is transparently noted on the credential.
Layered. (1) A SHA-256 hash of the image is registered server-side at capture time. (2) The credential is signed with a server-held key — we can prove we generated it; you can't forge it. (3) Coming soon: the JPEG itself will carry a C2PA manifest, so even outside our platform any C2PA-aware tool (Adobe Verify, Chrome's Content Credentials) can independently confirm authenticity.
Yes. Photos and watermarks are generated entirely on-device. The "witness" step queues if offline and uploads when connectivity returns. The credential timestamp uses the time of the original capture (witnessed when you get back online), so off-grid shoots aren't penalized.
Honestly? Instagram, X, WeChat, and most social platforms strip EXIF metadata, so an embedded C2PA manifest is lost there. That's why we lead with the route that always works: a public verify.trustampcamera.com URL that holds up on any platform, even after compression and EXIF stripping. Coming soon, a second route — the C2PA manifest embedded in the original JPEG — will add tool-native verification (email, Dropbox, AirDrop, Adobe tools) on top.
C2PA manifests in the photo are coming soon. Once shipped, because Trustamp uses the open C2PA standard, the manifest in your JPEG will be readable by any C2PA-aware tool — without using Trustamp at all:
trustampcamera.com/verify/<id> — the public route, even after platforms strip EXIFImportant: V1 pre-launch trust tier. Trustamp's signing certificate is currently self-issued — our C2PA Trust List application is in progress. This means tools above will read the credentials fine, but mark the issuer as "untrusted" until our Trust List inclusion. Timemark photos, by contrast, can only be verified on timemark.com — there's no open standard, no cross-tool reading, no independent verification.
Free forever for the watermark camera. Around $2/mo for the Lite tier (witnessed timestamps with 1,000 witnesses included). Around $5–9/mo for Pro (full C2PA credentials + verify URL + PDF export). Final pricing locked before launch — early waitlist members get a permanent discount.
One email when Trustamp is live. Early signup gets locked-in pricing and Pro features at Lite price for 12 months.
