Evidence is only as strong as its integrity. A photo can be edited, a timestamp can be changed, and metadata can be stripped. PackProof evidence is sealed with SHA-512 cryptographic fingerprints — making any alteration immediately detectable.
A photograph or video is not evidence unless its integrity can be proven. Standard digital media fails this test in every way that matters.
Without cryptographic verification, any photo or video can be altered and presented as original. Standard media formats offer no way to detect whether a file has been modified.
EXIF timestamps, GPS data, and device information can be modified with free tools. The very data that should prove when and where a photo or video was taken is trivially changeable.
Opposing parties routinely question whether photos were taken when and where claimed. Without a verification mechanism, there is no way to answer these challenges definitively.
Informal photos increasingly fail to meet the documentation standards required in formal proceedings. A photo from a camera roll is not evidence — it is an assertion.
The problem is not the camera — it is the format. Standard photo formats were designed for sharing, not for proving.
Standard photo formats have no built-in way to prove a file has not been altered. There is no checksum, no signature, no seal.
Device timestamps can be changed before or after capture, making them unreliable as evidence. A timestamp that can be edited is not a timestamp — it is a claim.
Uploading a photo to Google Drive or Dropbox does not certify it or create a chain of custody. Cloud storage preserves files — it does not verify them.
Sharing photos via WhatsApp, email, or SMS often removes the very metadata that could support a claim. The act of sharing destroys the evidence.
Recipients of a standard photo have no way to independently verify its authenticity. They must take the sender's word — which is not verification.
PackProof does not just store your photos and videos — it certifies them. Every capture is cryptographically sealed, server-verified, and independently auditable.
Every capture is sealed with a unique digital fingerprint that changes if even a single pixel is altered. Tampering is not just difficult — it is mathematically detectable.
Capture time is verified by PackProof servers, not the device clock, making timestamps immutable and independently verifiable. No one can backdate evidence.
Every action on every piece of evidence is logged in a tamper-proof audit trail, from capture to retrieval. The complete history is preserved and verifiable.
A standalone document containing the fingerprint, timestamp, GPS, and verification status — shareable with any party. Recipients can verify independently without a PackProof account.
Four steps from capture to verifiable certificate. No special equipment required.
Staff photographs or records items using PackProof on any device. No special hardware or training required — open the app and capture photos or video.
A unique cryptographic hash is created at the moment of capture. This fingerprint is mathematically unique to the exact file contents.
Timestamp and geolocation are verified server-side, not by the device. This removes the device as a point of trust.
A downloadable verification certificate is generated, independently verifiable by any recipient. Share it with insurers, customers, or legal teams.
