Most discussion of electronic trust focuses on signatures — but signatures belong to people. When an organisation itself needs to vouch for a document, the right instrument is the electronic seal. Seals let a legal entity, rather than an individual, prove that a document came from it and has not been altered — and they do it at a scale no human signer could match.
Seals versus signatures
An electronic signature is created by a natural person and expresses their intent. An electronic seal is created by a legal person — a company, authority or institution — and guarantees the origin and integrity of a document. A signature says "I, this individual, agree"; a seal says "this organisation issued this, and it is genuine." The distinction matters legally and operationally.
What makes a seal qualified
Like signatures, seals come in tiers under eIDAS, up to the qualified electronic seal. A qualified seal is backed by a qualified certificate issued to the organisation and created with a qualified seal creation device. It carries a strong legal presumption of integrity and of correct origin — the organisational equivalent of a qualified signature's evidentiary power.
Where organisations use seals
- Invoices and financial documents: proving authenticity and integrity for compliance and automated processing.
- Certificates and official records: diplomas, attestations and credentials issued at volume.
- Automated and bulk issuance: sealing thousands of documents programmatically, with no human in the loop.
- Statements and reports: confirming that a document genuinely originates from the issuing body.
Integrity and origin at scale
Because a seal represents the organisation rather than an individual, it is ideally suited to automation. A back-office system can apply a qualified seal to every outgoing invoice or certificate via an API, embedding tamper-evidence and verifiable origin into high-volume document flows. Recipients — and auditors — can verify in seconds that a document is authentic and unaltered.
