Provika - Evidence Dashcam

Provika captures photos and videos when the time, place, and integrity of the original matter.

WHAT IT DOES
Time, location, and device context are burned into the frame as you shoot, so they are readable without any special tool. When capture ends, Provika hashes the original, signs it with a key held in your device's secure hardware, and publishes an evidence package containing the original media, a canonical claim, and the signature envelope.

VERIFY WITHOUT A SERVICE
Verification runs on the device with no network. The package carries its own public key, so anyone can check it independently. Provika never uploads your captures — it has no backend to upload to.

HARDWARE-BACKED SIGNING
The signing key is created inside the Android Keystore, using StrongBox where the device supports it. On supported devices the package can also carry a certificate attesting that the key was created in real secure hardware. That certificate is a fact about the key, not about what was captured.

QUICK CAPTURE
Start without hunting for the app: a quick settings tile, a home screen widget, a launcher shortcut, and volume-key capture. Long recordings keep running behind a foreground notification.

BUILT FOR THE FIELD
A large record button, a separate photo button, and zoom presets you can tap — 0.6x, 1x, 2x, 5x. Drag the presets to fine-tune on a ruler. A pre-record buffer keeps the seconds before you pressed the button.

EXPORT AND SHARE
Export a verified package as a ZIP with a readable PDF report in English, Korean, Simplified Chinese, Traditional Chinese, or Japanese. Only packages that pass verification are exported.

WORKS WITH THE IPHONE EDITION
Provika for iPhone and Provika for Android share one evidence format. A package made on either platform is verified by the other.

WHAT PROVIKA DOES NOT CLAIM
Provika provides technical integrity information. A hash helps detect whether media changed after the package was created; time and location are observations reported by the device. Provika does not replace forensic analysis, does not determine legal admissibility, and does not guarantee acceptance by any organization. Follow local law and respect privacy when recording, exporting, or sharing.
