Documents signed by real people.
Not just email clicks.
Proveium Sign uses biometric identity verification so every signature is backed by an auditable identity record — not a checkbox.
Signature integrity by architecture
A name in a box is not a signature. Proveium Sign bonds the signature to a verified identity.
Biometric signatures
Every signature is backed by a biometric verification event — not just a name typed into a box.
Defensible evidence
Verified identity at the point of signing creates an auditable record built for legal review.
Audit trail
If a signature is ever disputed, you have a complete chain of custody ready for legal review — timestamped and identity-bound.
Qualified-signature pathway
Designed to support advanced and qualified signing workflows with verified identity evidence.
Identity-bound signing
The signatory's verified identity is cryptographically bound to the signature — not just their email address.
Tamper-evident documents
Any change to the document after signing invalidates the signature. The integrity is mathematical, not procedural.
Multi-jurisdiction
Supports legal validity of electronic signatures in the UK and EU — jurisdiction-appropriate signing levels apply automatically. Legal admissibility of any specific agreement depends on your jurisdiction and use case.
Verifiable without calling us
Signatures are verifiable credentials — authorised reviewers can verify independently of Proveium.
An email click is not a signature.
Most e-signature platforms verify nothing. Anyone with access to an email inbox can sign. When a dispute lands, you must prove who signed — and without biometric evidence, that is nearly impossible.
Identity is never checked
Clicking a link proves email access. It does not prove the person is who they claim to be. Signers are unverified strangers.
Proving identity falls on you
If a signature is disputed, you must evidence the signer's identity. Without biometric evidence on record, that case is harder to support.
IDV is a hidden add-on cost
Most platforms charge £1.35–1.85 per identity check on top of the licence fee. A 20-sig/user/month team pays £27–37 extra per user before any dispute costs.
How it works
Two paths. One verification standard.
Every document you send carries cryptographic proof of who signed and when — not just a timestamp.
Where Proveium Sign applies
Every document type where an email click creates legal or compliance exposure.
