    Why Timestamps and Metadata Matter for Evidence

    Timestamps matter because every legal, insurance, and HR dispute eventually asks when. Standard phone metadata can be edited in seconds. A verified timestamp from an independent authority, paired with GPS and a cryptographic fingerprint designed to detect later changes, turns your photo into independently verifiable evidence rather than a date anyone can dispute.

    Your phone's timestamp can be faked in 30 seconds. Here's what actually works.

    The Problem With Your Camera Roll

    Every photo your phone takes includes metadata — date, time, location, device. Most people think this proves when a photo was taken. It doesn't. Anyone with a free app can change photo metadata in seconds — it's one of the biggest evidence mistakes people make. Change the date, the location, whatever you want. Metadata alone is not evidence — it's data that can be manipulated.

    What Is a Verified Timestamp?

    A verified timestamp comes from an independent, trusted third party — not your phone. Organizations like DigiCert (the same company securing major banks and governments) issue RFC 3161 timestamps. This is a cryptographic proof that a specific file existed at a specific moment. It cannot be backdated. It cannot be altered. It's the digital equivalent of a notary stamp — and it's central to what courts accept as digital evidence.

    What Is a File Hash?

    When evidence is created, a unique digital fingerprint called a SHA-256 hash is generated. Think of it like DNA for your photo. If even one pixel changes — a crop, a filter, any edit — the hash changes completely. This proves the file you're presenting is exactly the same file originally captured.

    How They Work Together

    Verified timestamp + file hash = proof that THIS EXACT FILE existed at THIS EXACT MOMENT. No one can claim you took it later. No one can claim you edited it. The math proves it.

    What Gets Burned Onto Your Evidence

    When you capture with SnapProof, the following is permanently burned onto your photo or video:

    Verification code (your evidence ID)
    Date and time of capture
    GPS coordinates
    Street address
    Device information

    This information cannot be removed or altered. It's visible to anyone who looks at the image — no special tools needed.

    Why "Burned On" Matters

    Metadata sits invisibly inside a file and can be stripped or changed. Information burned directly onto the image is visible to anyone. A judge, a lawyer, an insurance adjuster — they can see the timestamp without any tools or trust in technology.

    FAQ

    Metadata can be presented, but it's easily challenged because it can be edited. Verified timestamps from independent authorities are significantly more credible.

    DigiCert is the world's leading certificate authority. They secure major banks, governments, and enterprises. Their RFC 3161 timestamps are internationally recognized.

    They could crop or edit the image — but doing so changes the file hash, proving it was tampered with. The original evidence remains protected.

    Don't hope they believe you. Prove it.
