Seal patient records, clinical protocols, and medical research data with ZertES and eIDAS-certified cryptographic timestamps. GDPR Article 32 compliant. Tamper-proof evidence for audits, courts, and regulatory inspections.
Healthcare organisations handle some of the most sensitive data in existence: patient records, clinical trial results, surgical notes, prescription histories, and medical research. The integrity of these documents is not merely a regulatory concern — it directly affects patient safety, litigation outcomes, and institutional liability. When a record is altered, whether through deliberate falsification or a system error, the consequences can be catastrophic.
GDPR Article 32 requires data controllers and processors to implement 'appropriate technical and organisational measures' to ensure data security — including the ability to ensure ongoing integrity and confidentiality of processing systems. Cryptographic sealing directly addresses this requirement by creating an immutable audit trail for every document.
Swiss Trust Layer applies qualified electronic seals under ZertES SR 943.03 and the European eIDAS Regulation. Each sealed document receives a cryptographic hash and timestamp that is mathematically impossible to alter retroactively. If a record is modified after sealing, the cryptographic signature immediately invalidates — providing instant tamper detection. This creates the kind of audit trail that satisfies regulators, courts, and insurers.
Switzerland's healthcare regulatory framework — including the Federal Health Insurance Act (KVG/LAMal) and the Medical Professions Act (MedBG) — places specific obligations on document integrity that align directly with cryptographic sealing capabilities. Swiss Trust Layer bridges the gap between technical capability and regulatory compliance.

Data Integrity Standard
Every division of a modern healthcare organisation generates documents that require integrity guarantees. Swiss Trust Layer protects the full document lifecycle — from initial creation to long-term archival.
Seal discharge summaries, consultation notes, and diagnostic reports at the point of creation. Cryptographic timestamps prove when records were generated and detect any subsequent alteration — critical for malpractice litigation and insurance claims.
GCP (Good Clinical Practice) requires complete, accurate, and verifiable trial records. Seal protocol amendments, informed consent forms, adverse event reports, and data lock notifications with court-admissible timestamps that satisfy EMA and FDA inspection standards.
Demonstrate GDPR Article 32 compliance with a verifiable audit trail. Sealed documents provide regulators with cryptographic proof that records were not modified after their creation — reducing the risk of enforcement actions and fines.
Research institutions face the same IP challenges as technology companies: who developed what, and when? Seal research datasets, laboratory notebooks, and grant applications to establish priority and protect against disputes over publication rights.
Swiss providers operating under KVG/LAMal and MedBG face specific document retention and integrity obligations. Swiss Trust Layer seals, issued under ZertES SR 943.03, are designed to meet Swiss federal standards and are recognised by Swiss courts and cantonal health authorities.
Integration into existing healthcare workflows requires no specialist IT knowledge. Documents can be sealed individually or in batches.
Upload patient records, clinical protocols, research data, or any healthcare document to Swiss Trust Layer. Supported formats include PDF, DOCX, XLSX, DICOM metadata files, and all standard healthcare document formats up to 500 MB.
Swiss Trust Layer applies a qualified electronic seal under ZertES SR 943.03. A cryptographic hash and qualified timestamp are permanently bound to the document. Any subsequent alteration — even a single character change — is instantly detectable.
A sealing certificate is generated containing the timestamp, document hash, and cryptographic signature proof. This certificate is publicly verifiable without login and can be provided to regulators, auditors, insurers, or courts as evidence of document integrity.
Sealed in under 60 seconds — audit-ready immediately
Document sealing completes in under 60 seconds. Certificates are immediately available for download and can be stored alongside the original document in your existing records management system. No changes to existing clinical workflows are required.
Swiss Trust Layer seals satisfy multiple overlapping regulatory requirements across European and Swiss healthcare law.
GDPR Article 32 requires controllers and processors to implement technical measures ensuring 'the ongoing confidentiality, integrity, availability and resilience of processing systems and services.' Cryptographic sealing directly implements the integrity requirement by making document tampering immediately detectable. For healthcare organisations processing special category data under Art. 9, this technical measure provides documented evidence of compliance during supervisory authority inspections. Compliance →
Under eIDAS Art. 35, a qualified electronic seal enjoys a presumption of integrity and accuracy of its origin. Seals issued through Swiss Trust Layer (via Swisscom Trust Services as accredited QTSP) satisfy this standard, meaning sealed healthcare documents carry a legal presumption of integrity in all 27 EU member states. This is directly relevant to cross-border data transfers and clinical trials involving multiple EU jurisdictions. eIDAS →
Switzerland's Federal Health Insurance Act (KVG, SR 832.10) and Medical Professions Act (MedBG, SR 811.11) require healthcare providers to maintain accurate, tamper-evident records for specified retention periods. Swiss Trust Layer seals are issued under ZertES SR 943.03, the Swiss federal standard for qualified electronic signatures, and are accepted by Swiss courts, cantonal health authorities, and the Swiss Federal Office of Public Health (FOPH/BAG).
