Qualified Electronic Seals (QSeals).
Summary
IDnow QSeals enable legal entities (e.g., banks, insurers, enterprises) to cryptographically protect the integrity and prove the origin of electronic documents at a qualified level under eIDAS. A qualified electronic seal is created by a qualified electronic seal creation device and based on a qualified seal certificate.
Service Description
Organizations often need a tamper-evident way to issue and distribute documents (contracts, statements, evidences, reports) at scale. QSeals address this by applying a qualified electronic seal using a certificate issued to a legal person, providing integrity and origin assurances. QSealing is typically performed in automated processes and can cover large batches of documents in one session.
Key Capabilities include:
- Qualified sealing of customer documents (API-first), where a customer applies a customer-specific or an IDnow Qseal to a customer-uploaded PDF;
- Combined flows of QSeal plus signer signatures, where documents need QES by the signer and QSeal by the organization (for example: all individuals sign first, then the organization seals), with flexible sequencing (QSeal before or after QES).
Credential and Onboarding Model (Operational Overview)
QSeal issuance requires that a long-term qualified certificate exists for the customer entity and that IDnow can apply the seal on behalf of the customer without requiring customer interaction at runtime.
Operationally, QSeal credential creation is initiated via offline onboarding (KYB) and an internal request process, followed by automated credential creation triggers and strict configurable customer linking for dedicated seal application. The process is designed for high-volume sealing scenarios, thus the supported document format is PDF.
Compliance Summary
- QSeals are the organizational counterpart of signatures: seals are created using certificates issued to legal persons to ensure integrity and origin.
- A QSeal specifically requires a qualified certificate and a qualified seal creation device.
