Hardsight

Durable proof of capture for photos and videos. Tamper-evident seals, public verification, vault-stored originals. Reality, sealed.

Hardsight seals your photos and videos with cryptographic proof so anyone can verify they are authentic and haven't been altered.

Every capture becomes a Proof Pack: a tamper-evident bundle signed with digital signatures and secured by cryptographic hashing. From the moment you press the shutter, Hardsight locks in what was capture, when, and where and makes it independently verifiable by anyone with a web browser.

How it works: open Hardsight and choose a capture profile, Quick, Standard, or Extended. Capture photos and/or video. Hardsight records timestamps from both your device and a network time source, and optionally confirms your location and identity with biometrics.

Hardsight seals your Proof Pack on our server, applying a digital signature that binds every file to a single cryptographic hash. Any change to any file, even a single pixel, breaks the seal.

Share a verification link. Anyone can open it in a browser to independently confirm your evidence is authentic and unmodified. You can also share badged photos, photos with verification cards attached and PDF proof bundles for professional applications.

Five layers of trust, built in: Hardsight doesn't ask anyone to take your word for it. Every Proof Pack carries up to five core independently verifiable trust signals: server attestation, device/app attestation, device signature, biometric confirmation (optional) in addition to GPS data (optional) and clock trust (multi-variable time verification). The public verification page shows exactly which layers are present and whether they align with the proof pack being authentic.

Free: 5 active Proof Packs, 14-day retention Personal: 100 packs, 6-month retention Pro: 1,000 packs, 1-year retention Archival add-ons available for long-term preservation (1, 3, 6, or 9 years)

Your proof, independently verifiable: every Proof Pack has a public verification link at hardsight.io. No account needed to verify, just open the link. Hardsight captures directly from the camera, no photo library imports, no uploads from other apps. What you see is what was there at the time of capture.
