The complete chain of trust from camera to certificate
VeriSources certifies who took it, when it was taken, where it was captured, and that it has not been altered — backed by blockchain, C2PA standards, and cryptographic proof.
Visual truth needs a verifiable chain
In an era of synthetic media and AI-generated imagery, the question is no longer just "does this look real?" — it is "can you prove it is real?" VeriSources answers that question with a complete, auditable chain of trust.
We connect a verified human identity, a confirmed phone number, an administrator-approved account, a hash-locked file record, and an optionally blockchain-anchored certificate into a single verifiable proof — publicly checkable by anyone with a certificate code.
On premium plans, C2PA manifests embed that proof directly into the image file, and OpenTimestamps anchors each certificate hash to the Bitcoin blockchain — creating a permanent, independently verifiable record that survives even if VeriSources itself is unavailable.
What VeriSources provides
Every plan includes the core trust infrastructure. Premium add-ons layer additional proof on top.
Identity-backed certificates
Every certificate is tied to a verified uploader account with confirmed phone ownership and manual admin approval — not just a file upload.
Dual hash fingerprinting
SHA-256 hashes of both the original and trusted derivative are recorded and locked at issuance. Any tampering is detectable via the public verify page.
Certificate PDF export
Every certified asset produces a branded certificate PDF with QR code, certificate code, hash values, and uploader metadata — ready for publishing.
Video certification
Video assets receive the same trust chain as images — uploader verification, hash locking, certificate issuance, and public verification by certificate code.
Public verification page
Anyone can verify a certificate by code without an account. The verification page shows the certificate details and supports file-hash comparison for the trusted file.
Mobile camera upload
Upload directly from your smartphone camera on any plan — no app download needed. iOS and Android both supported via the mobile-optimised upload workflow.
Premium trust add-ons
Available on selected paid plans. Each add-on is rated by the strength of proof it provides and explained in full below — including exactly how it is embedded into the image or certificate.
The Coalition for Content Provenance and Authenticity (C2PA) is the open industry standard for provenance metadata, backed by Adobe, Microsoft, Intel, the BBC, and over 300 organisations. When enabled, VeriSources embeds a signed C2PA manifest directly into the trusted image file at certification time — meaning provenance data travels with the file.
Tools like Adobe Content Credentials, Microsoft's Content Integrity feature, and AI detection platforms can read the embedded proof without ever contacting VeriSources. This is the recognised standard for newsrooms and publishing workflows.
c2pa: namespace fields declare the claim generator, manifest URL, and provenance assertion type so any C2PA-aware tool recognises it immediately.
- C2PA 1.x manifest embedded in JPEG/PNG
- Signed provenance assertion in XMP
- Readable by Adobe, Microsoft & others
- Proof travels with the certified file
- AI-detection platform compatible
- Newsroom-ready provenance signal
At the exact moment of certificate issuance, VeriSources records the precise timestamp, GPS coordinates (if the device permits), and a device integrity hash. These values are cryptographically signed and sealed into the certificate record using HMAC-SHA256 — they cannot be altered after issuance without detection.
This makes the when and where of an image independently auditable. Combined with the uploader's verified identity, this is the same kind of chain-of-custody evidence used in professional photojournalism and legal documentation workflows.
- Cryptographically signed timestamp
- GPS coordinates sealed at upload
- Device integrity hash included
- Tamper-evident after issuance
- Chain-of-custody ready
- Legal documentation compatible
When this add-on is active, every certificate issuance submits the certified file's SHA-256 hash to the OpenTimestamps public calendar. The hash is aggregated into a Merkle tree alongside thousands of other hashes and anchored to the Bitcoin blockchain in a single transaction — creating a permanent, tamper-evident proof that this exact hash existed at this exact time.
OpenTimestamps is an open standard created by Bitcoin core contributor Peter Todd, used by major institutions including IETF and academic publishers. It requires zero fees, zero accounts, and zero credentials. The proof survives independently of VeriSources — it is anchored in the most widely audited public ledger on earth.
.ots file directly from the public verify page and verifiable offline using ots verify or by uploading it to opentimestamps.org. No VeriSources account or server is needed for verification — only the Bitcoin blockchain, which is publicly accessible worldwide.
.ots file and the Bitcoin blockchain — no login, no trust in VeriSources required. Bitcoin confirmation takes ~10 - 20 minutes after issuance; the receipt is valid immediately.
- Bitcoin-anchored, permanently verifiable
- No account or API key required
- Receipt stored & downloadable from verify page
- Verify at opentimestamps.org or via CLI
- Open standard, not vendor-locked
Mobile Camera Certification — No App Required
VeriSources is a mobile-first web platform. The upload workflow uses standard browser file capture APIs to open the device's native camera directly — no third-party app, no QR code scanner, no extra download needed. Works on iOS Safari and Android Chrome out of the box.
When combined with the Timestamp & Location add-on, images captured directly through the browser workflow carry the GPS coordinates and capture time from the device — creating an unbroken chain from the physical moment of capture to the issued certificate.
- Works on iOS Safari & Android Chrome
- No app download required
- Native camera API integration
- GPS & timestamp captured at shoot
- Pairs with Timestamp add-on for full proof
- Secure upload over HTTPS
