EXIF timestamps embedded in photos can be altered in seconds. SHA-512 cryptographic sealing creates tamper-proof records that no amount of editing can fake.
Many businesses rely on photo metadata to prove when packing occurred or inspection was completed. But EXIF timestamps are embedded *inside* the image file — and can be changed without leaving a trace.
Any basic photo editor or metadata tool can change EXIF timestamps after the fact. An employee, third party, or claimant can alter the date/time recorded in a photo, and no one inspecting the image can tell it was modified. This makes timestamp evidence worthless in disputes.
EXIF data lives inside the image file itself. If the file is edited (cropped, brightened, objects removed), the timestamp often remains unchanged — or the entire EXIF block can be stripped and rewritten. You have no way to verify the photo hasn't been altered since capture.
In chargebacks, insurance claims, or customer disputes, opposing counsel immediately questions whether EXIF timestamps are genuine. Without cryptographic proof, you're arguing the timestamp is real — but your evidence is the timestamp itself. It's circular and legally weak.
When packing photos are taken in quick succession with identical timestamps or sequential ones, disputes handlers assume batch editing or backdating. Legitimate process photos should show natural time gaps, but this reasoning penalises legitimate fast workflows and fuels false disputes.
EXIF data is descriptive information stored *within* the image file. It tells you what a camera *claims* about timing, but it has no independent verification mechanism. Changing it requires no special knowledge and leaves no forensic trace — unlike cryptographic hashing.
A photo with EXIF metadata doesn't prove when that metadata was created. The photo file can be copied, edited, re-exported, or transferred between devices — each step risking timestamp loss or alteration. There's no sealed, immutable record of the timestamp's integrity.
Courts and insurers increasingly demand evidence that cannot be modified without detection. EXIF timestamps fail this standard because the file and its metadata are coupled — edit one, and both can change together. Judges and claims handlers know this, which is why EXIF-only evidence is rejected.
The timestamp in a photo depends on the device's internal clock. A user can set their phone or camera to any date and time before capture. EXIF timestamps therefore prove only what the device's clock said at the time of capture — not when capture actually occurred.
Modern photo editing software (Photoshop, mobile apps, online tools) can modify images and metadata with a single click. No visual indicator shows that EXIF data has been altered. This makes it impossible for dispute handlers or legal teams to distinguish genuine photos from edited ones after the fact.
PackProof seals photos and videos at the moment of capture with SHA-512 cryptographic hashing. Unlike EXIF timestamps, this hash is mathematically tamper-proof — any change to the image invalidates the hash, creating instant, auditable evidence of tampering.
SHA-512 hashing creates a unique digital fingerprint of each photo or video at the moment of sealing. If even one pixel changes, the hash becomes invalid. This gives you cryptographic proof the image is identical to what was captured — no timestamp guessing required.
PackProof timestamps are sealed *with* the SHA-512 hash and stored separately in the cloud. They cannot be changed without invalidating the hash. This breaks the coupling between image and metadata, creating independent proof of when sealing occurred.
When a chargeback, claim, or customer complaint arrives, you retrieve the sealed evidence immediately. The hash verification is instant — no forensic analysis required. Claimants cannot argue the photo was edited because the hash proves it wasn't. Photos and videos are equally sealed and equally verifiable.
Courts and insurers recognise SHA-512 certification as mathematically sound evidence of integrity. Unlike EXIF timestamps, which rely on device clocks and metadata standards, cryptographic hashing is universally accepted as tamper-proof. Your sealed photos and videos withstand legal scrutiny automatically.
Use PackProof's mobile app to photograph the packed items before sealing the box, or record video of the packing process. Capture inspection checklists, condition close-ups, sealed tape, or labels — PackProof handles both photo and video formats natively, and each is sealed with equal cryptographic protection.
The moment you capture a photo or video, PackProof computes its SHA-512 hash and stores it alongside an immutable timestamp. The seal is created at the source, before the file leaves your device. No editing, no processing, no delay — the image is cryptographically locked at the moment of capture.
Sealed photos and videos are uploaded to PackProof's secure cloud storage. The hash and timestamp are stored separately from the image itself, ensuring that neither can be altered without detection. Your team can access sealed evidence immediately, and role-based controls limit who can view sensitive images.
When a customer claims an item was damaged, missing, or wrong, retrieve the sealed photo or video evidence instantly. PackProof shows the hash validation status (green = unchanged, red = tampered). No guessing whether the evidence is genuine — cryptographic proof is automatic and admissible.
PackProof's SHA-512 certification eliminates timestamp disputes forever. Capture photos and videos knowing they're cryptographically locked the instant you press record. Try it free for 14 days — no credit card required.
