Certification turns a photo or video into legally defensible proof. Here’s the technical process that makes packing evidence tamper-proof and verifiable.
Photos and videos are only useful as evidence if you can prove they haven’t been modified. Without certification, recordings are just files—and files can be edited.
EXIF data on photos—timestamps, GPS coordinates, device information—can be changed with free software in seconds. Dispute reviewers know this and treat uncertified metadata as unreliable.
Without a cryptographic timestamp, there is no way to verify when a recording was actually made. A photo could have been taken before, during, or after a disputed event.
The moment a file leaves the capture device—copied to a laptop, uploaded to cloud storage, emailed to a colleague—the chain of custody is broken unless the file is sealed at source.
Payment processors, insurers, and marketplace dispute teams increasingly require evidence that can be independently verified. Unsecured photos are routinely dismissed.
Certification is a specific technical process, not a label. It involves three layers that together make a recording independently verifiable.
A SHA-512 hash is a unique 128-character fingerprint generated from the file’s binary content. If even a single byte changes, the hash changes completely—making any alteration detectable.
The exact date and time of capture is recorded and locked at the moment of sealing. This timestamp cannot be backdated or modified after the fact.
The certification links the recording to a specific user, device, and location. Every access and download is logged, creating an auditable trail from capture to dispute submission.
Anyone with the verification certificate can recalculate the SHA-512 hash against the original file and confirm it matches. No trust in the certifying party is required—the maths speaks for itself.
Certified packing photos and videos shift the burden of proof. Instead of defending your word, you present independently verifiable documentation.
Any modification to the original recording produces a different hash. A dispute reviewer can verify authenticity in seconds by comparing the certificate hash to the file.
SHA-512 is a NIST-standardised algorithm used in government, finance, and legal contexts. Certified recordings carry the same cryptographic weight as digitally signed documents.
When evidence is pre-certified, there’s no back-and-forth about authenticity. Dispute teams can evaluate the content immediately rather than questioning the documentation itself.
Each verification certificate bundles the visual evidence, SHA-512 hash, timestamp, packer identity, and GPS coordinates into a single downloadable PDF.
Photograph or record the packing process on any camera-equipped device. The photo or video captures item condition, quantity, and packaging.
PackProof processes the file through the SHA-512 algorithm the moment the photo or video is saved. The resulting 128-character hash becomes the evidence’s unique fingerprint.
The capture time, GPS coordinates, device identifier, and packer identity are locked alongside the hash. All metadata is sealed against modification.
Retrieve the certificate by order number when needed. The PDF includes the hash, timestamp, and visual evidence—ready for submission to any dispute process.
Every photo and video sealed with SHA-512, timestamped, and ready for disputes. Free 14-day trial — no credit card required.
