ProofShot

ProofShot is a recording app that automatically records location information and a timeline before and after a photo is taken, linking the content of the photo to the actions taken before and after it to enhance the quality of evidence.

◆ Automatically Records GPS History Before and After Shooting
Not only can it record the GPS location at the moment the photo was taken, but it also records the location of the person before and after the photo was taken.
This allows you to demonstrate the continuity of actions and the fact that someone was present in a certain location in a chronological order, something that is difficult to prove with a simple photograph.

◆ Automatically Adds Location, Time, and Device Information
- Adds GPS location information to each photo
- Records highly accurate photo date and time
- Automatically generates signature data including device information
- SHA-256 hashing can also detect data tampering

◆ All data is stored exclusively on the device
ProofShot prioritizes privacy and does not send photo data or GPS history to external servers.
All data remains solely on the user's device.
