Qualified e-Seal Β· Data Integrity Β· AI Act

Prove your data hasn't
been touched since the moment it was created.

WeVerify's qualified e-seal applies a cryptographic stamp to any document, dataset, video, or data stream, proving its origin and detecting any modification after the moment of sealing. Required for AI Act Article 13 data provenance, insurance-grade IoT records, and court-admissible document evidence.

What you can seal

Documents, data streams, video sessions, and AI content.

Documents & contracts

Legal agreements, invoices, certificates, reports, and regulatory filings. The seal proves the document existed in its current form at the moment of sealing.

AI training data

Prove the provenance and integrity of AI training datasets under EU AI Act Article 13. Required for high-risk AI systems that must demonstrate data lineage.

IoT sensor data

Seal telematics, environmental sensor readings, and device logs at the point of generation, making them usable as insurance evidence and regulatory compliance records.

Video sessions

Cryptographically seal recorded video sessions, notarial acts, identity-gated calls, and compliance recordings, producing a tamper-detectable court-admissible record.

Regulatory drivers

Sealing is becoming mandatory, not optional.

βš–οΈ
EU AI Act, Article 13: Data Provenance
High-risk AI systems must maintain records proving the provenance, integrity, and processing history of training data. WeVerify's e-Seal creates a cryptographic record at the point of data collection that satisfies Article 13 requirements and provides an auditable chain of custody for the data lifecycle.
πŸš—
Automotive & IoT, Insurance and Regulatory Evidence
Telematics data used for insurance pricing, maintenance warranty claims, and regulatory reporting must be verifiably unaltered. Without cryptographic sealing, the data chain is legally unreliable. WeVerify seals data at source, making it admissible evidence from the point of generation.

eIDAS 2.0, Qualified e-Seal
The qualified e-seal under eIDAS 2.0 carries the same legal standing as a qualified biometric signature for organisations. It proves that a legal entity has issued or approved a document, a stronger assurance than an advanced seal and legally recognised across all EU member states.

Prove your data is exactly as you left it.

Book a demo and we will seal a sample document live, then demonstrate tamper detection by modifying it and showing the verification failure.
