What This Proves.

The precise evidentiary scope of a Digital Witness certificate — what the method establishes as objective fact, and what lies outside its intended purpose.

What this method proves.

A Digital Witness certificate establishes the following verifiable technical facts:

1. Existence. The digital content existed at a specific, provable point in time.

2. Integrity. The content has not been altered since that moment. Any change — even a single byte — invalidates verification.

3. Continuity. The content has maintained a continuous, unbroken integrity chain from capture to verification.

4. Control context. At the time of witnessing, the content was sealed under the control of a specific account or system context.

These facts are established using cryptographic hashing, digital signatures, and immutable recording mechanisms. They do not rely on trust in Witnium, system administrators, or any human actor.

What this method does not prove.

The Digital Witness method does not, on its own, determine:

×Legal ownership or title.
×Authorship or creative intent.
×Truthfulness, accuracy, or legality of the content's substance.
×Contractual meaning or interpretation.

This is intentional. In legal and compliance practice, integrity of evidence is treated as a foundational technical question — distinct from questions of intent, meaning, or rights, which are assessed separately.

Legal parallel.

Just as a notarised document does not prove what the document means — only that it existed in a certain form at a certain time — a Digital Witness certificate provides technical integrity assurance, not legal conclusions.

Court-facing summary.

A Digital Witness certificate establishes objective, technical facts regarding the existence and integrity of a specific digital file. At the moment of capture or upload, a cryptographic fingerprint of the file's exact contents is computed and permanently recorded as a witness. This fingerprint uniquely represents the file in that specific state at that specific time.

If the original file is later presented, its fingerprint can be independently recomputed and compared to the fingerprint recorded in the certificate. A match demonstrates that the file is byte-for-byte identical to the file that was witnessed. Any modification, substitution, or alteration would result in a different fingerprint and fail verification.

The method does not, on its own, determine legal ownership, authorship, intent, or substantive truthfulness. It provides technical proof of existence, integrity, and continuity — which may be evaluated together with other evidence in legal or regulatory proceedings.

These summaries describe the technical method used to establish digital integrity and continuity. They do not constitute legal advice and do not determine legal conclusions, which remain subject to judicial assessment.
