What Lanveris Proves, and What It Does Not
Lanveris preserves verifiable facts: which byte sequence was registered, before which trusted time, with which metadata, and whether later bytes still match. It does not replace contracts, copyright registration, or legal judgment.

Definition
Lanveris provides trusted timestamp evidence and fingerprint verification. Product copy may call this proof, but technically it is not a legal authority granting rights.
What it can prove
Under practical SHA-256 security assumptions, a file fingerprint was registered no later than the trusted timestamp.
A record can include description, agent label, claimed account information, and batch information. These are registration metadata, not automatic proof of real-world identity or ownership.
If the file bytes change later, recalculating the fingerprint will not match the original record.
What it cannot prove
It does not prove originality, copyright ownership, legal compliance, or that infringing content became lawful because it was registered.
It does not prove a photo or video was genuinely captured, was not staged, or was not AI-generated. It also does not verify the prompt, model, runtime, or full creation process.
It does not replace contracts, copyright registration, forensic analysis, C2PA, device signatures, or evidence cameras. Those can complement Lanveris evidence.
When it is useful
Lanveris is useful when the question is: did this exact content exist before a trusted time, and does it still match the registered bytes?
It fits delivery records, agent output archives, material handoff, pre-publication evidence packages, and later licensing or issuance preparation.
FAQ
Why call it proof?
It is product language for a timestamped evidence trail. Strictly, Lanveris provides trusted timestamp evidence and fingerprint verification, not legal confirmation of ownership.
What if someone registers another person's content?
Lanveris can show that this content was registered before a trusted time. It cannot make the registrant the lawful owner. Disputes still depend on facts, contracts, and law.
How is online verification different from offline credentials?
Online verification calculates a fingerprint locally and checks public records. Offline verification uses the .lanveris credential to verify the Merkle path and TSA timestamp evidence.
