Electronic signature healthcare sector: GDPR & HDS

Introduction: digital transformation of healthcare establishments

The healthcare sector is one of the most demanding environments in terms of data security and regulatory compliance. In 2026, more than 73 % of French healthcare establishments report having begun their document digitalisation (source: ANS report 2025). However, electronic signature in the healthcare sector remains underutilised, hindered by legitimate questions about GDPR compliance, health data hosting (HDS) and the requirements of the eIDAS regulation. This article provides you with a comprehensive framework for understanding the challenges, choosing the right signature level and deploying a sovereign solution adapted to the specificities of healthcare.

1. Why electronic signature has become essential in healthcare

1.1 Massive and constraining document volume

A French university hospital produces on average 4 to 6 million documents per year: prescriptions, informed consents, employment contracts, inter-establishment agreements, admission forms, medical expertise reports. Manuscript signatures generate average delays of 5 to 12 working days for documents requiring several successive validations.

Healthcare electronic signature reduces these delays to a few hours, whilst offering superior legal traceability compared to paper. For territorial hospital groupings (GHT), multi-site signature flows make digitalisation no longer optional but strategic.

1.2 Priority documents affected

Priority use cases in the healthcare sector cover:

• Patient informed consent: mandatory before any invasive procedure (article L.1111-4 of the French Public Health Code), it must be dated, named and kept on file.

• Contracts and amendments for healthcare professionals: independent doctors, nurses, temporary workers; signature delays directly impact schedules.

• Partnership agreements and clinical research protocols: subject to multi-layer validation requirements (sponsor, investigator, CNIL, CPP).

• Electronic prescriptions and orders (digital prescription): governed by the Mon Espace Santé programme and ANS reference frameworks.

• Hospital public procurement: governed by the Public Procurement Code and qualified signature requirements.

2. GDPR and health data: specific obligations to master

2.1 Health data as a special category under GDPR

The General Data Protection Regulation (GDPR, n°2016/679) classifies health data as sensitive data (article 9). Their processing is in principle prohibited, except for explicit exceptions: explicit consent from the data subject, necessity for medical care, or public interest in the healthcare field.

In the context of electronic signature, any solution that collects, transmits or stores data enabling identification of a patient or healthcare professional in a medical context processes health data in the broad sense. This entails:

• The appointment of a Data Protection Officer (DPO) mandatory for healthcare establishments (article 37 GDPR).

• Conducting a Data Protection Impact Assessment (DPIA) where processing is likely to pose a high risk.

• Compliance with the data minimisation principle: collect only information strictly necessary for the signature act.

• Implementation of appropriate technical and organisational measures: end-to-end encryption, pseudonymisation, access controls.

2.2 Data location: a sovereignty issue

Article 44 of the GDPR strictly governs data transfers outside the European Union. For healthcare establishments, choosing an electronic signature solution hosted in the United States or in a third country without an adequacy decision poses major legal risks: CNIL penalties reaching 4 % of global turnover or 20 million euros.

The CNIL explicitly recommends using service providers hosting their infrastructure within the European Union, ideally in France for the most sensitive health data.

2.3 Health Data Hosting (HDS): mandatory certification

Since the law of 26 January 2016 modernising the healthcare system (codified in article L.1111-8 of the French Public Health Code), health data hosting must be entrusted to a hosting provider certified HDS (Health Data Hosting Provider) by the ANS (Health Digitisation Agency).

This certification, based on the ISO 27001 standard extended to HDS specificities, covers six activities including infrastructure provision, managed services and information systems hosting. An electronic signature solution used in a medical context must therefore be hosted on HDS-certified infrastructure or rely on a certified sub-processor.

Certyneo hosts all its data on cloud infrastructure certified HDS and ISO 27001 located in France, in compliance with ANS requirements. Consult our dedicated page on electronic signature in healthcare to discover our technical architecture.

3. eIDAS, signature levels and strategic choice for healthcare

3.1 Three levels of electronic signature under eIDAS

The European regulation eIDAS (n°910/2014) and its evolution eIDAS 2.0 (EU Regulation 2024/1183) define three levels of electronic signature, the choice of which determines probative value and technical requirements:

| Level | Description | Typical medical use | |---|---|---| | SES (Simple) | Electronic data attached to other data | Acknowledgements of receipt, internal forms | | SEA (Advanced) | Linked to the signatory, detects any modification | Consents, HR contracts, agreements | | SEQ (Qualified) | Highest level, qualified creation device, qualified trust service provider | Public procurement, notarial acts, clinical research |

For the majority of common medical acts (informed consents, employment contracts, digital prescriptions), advanced electronic signature (SEA) offers the best balance between security level and ease of use. Hospital procurement and certain clinical research protocols require qualified signature (SEQ).

For further information on regulatory levels, consult our comprehensive guide on the eIDAS regulation.

3.2 Digital identity of healthcare professionals: CPS and Pro Santé Connect

In France, healthcare professionals have the Health Professional Card (CPS), issued by the ANS, which constitutes a recognised means of electronic identification. The Pro Santé Connect solution, the healthcare equivalent of FranceConnect, allows strong authentication of professionals.

An electronic signature solution intended for the healthcare sector should ideally be compatible with these sectoral digital identity devices to achieve the level of advanced or even qualified signature required by certain document flows.

3.3 ETSI compliance and qualified trust service providers

Qualified trust service providers (QTSP) listed on the European Trust List (TSL) guarantee that their services comply with ETSI standards EN 319 132 (XAdES), EN 319 122 (CAdES) and EN 319 162 (ASiC). In France, the ANSSI publishes and maintains this national trust list.

For healthcare establishments, relying on a SaaS editor that itself relies on a QTSP referenced by ANSSI is an essential guarantee of the legal value of signed documents.

4. Deploying electronic signature in a healthcare establishment: practical guide

4.1 Map document flows and identify priorities

Before any deployment, a mapping of document flows is essential. It must identify for each document type: the number of signatories, the required signature level, data sensitivity and time constraints.

A medium-sized GHT will prioritise patient consents (high volume, immediate gains), followed by HR contracts (impact on attractiveness), and finally inter-establishment agreements (multi-signatory complexity).

4.2 Integration into the hospital information system (HIS)

Healthcare electronic signature is only effective if it is natively integrated into existing tools: EHR (Electronic Health Record), HR scheduling software, document management tools (DMS). Modern solutions offer REST APIs and native connectors for the main HIS on the market (Mediboard, Hopital Manager, etc.).

Certyneo offers documented APIs enabling integration in less than 48 hours in most hospital environments. You can estimate the return on investment of this deployment using our dedicated ROI calculator.

4.3 Training teams and supporting change

The human factor is often the main obstacle to digitalisation in healthcare. Healthcare professionals have extreme time constraints and low tolerance for technological friction. A signature solution must therefore be:

• Accessible on mobile (signing on the move, between consultations)

• Intuitive in fewer than 3 clicks for the signatory

• Compatible with existing approval workflows (department head validation, management)

A short training programme (maximum 2 hours) combined with video tutorials integrated into the tool enables adoption rates exceeding 85 % within the first 30 days.

Conclusion: HDS-GDPR compliance, an investment, not a constraint

Electronic signature in the healthcare sector is no longer an optional subject. Between increasing regulatory obligations (GDPR, HDS, eIDAS 2.0, Mon Espace Santé programme), pressure on administrative timescales and cybersecurity challenges (healthcare is the most targeted sector by cyberattacks in France in 2025 according to ANSSI), establishments that have not yet deployed a sovereign and certified solution are taking major legal and operational risks.

Certyneo offers the most comprehensive solution on the French market to simultaneously meet HDS-GDPR-eIDAS compliance requirements and the operational needs of medical and administrative teams.

Legal framework applicable to healthcare electronic signature

Civil Code and probative value

Article 1366 of the French Civil Code establishes the principle of equivalence between electronic signature and manuscript signature: "An electronic document has the same probative force as a document on paper support, provided that the person from whom it emanates can be duly identified and it is established and preserved in conditions such as to guarantee its integrity." Article 1367 specifies that "the reliability of this process is presumed, unless proven otherwise, where the electronic signature is created, the signatory's identity ensured and the document's integrity guaranteed, under conditions laid down by decree by the Council of State." This decree (n°2017-1416 of 28 September 2017) explicitly refers to the requirements of the eIDAS regulation for qualified signatures.

eIDAS Regulation and eIDAS 2.0

The EU Regulation n°910/2014 (eIDAS), supplemented by EU Regulation 2024/1183 (eIDAS 2.0) which entered into progressive application from March 2024, establishes the European legal framework for trust services. It distinguishes three signature levels (simple, advanced, qualified) whose technical requirements are specified in ETSI EN 319 132 (XAdES), ETSI EN 319 122 (CAdES) and ETSI EN 319 401 (general requirements for TSP) standards. Qualified signatures have equivalent value to a manuscript signature in all member states.

GDPR and health data

The EU Regulation n°2016/679 (GDPR), articles 9, 35, 37 and 44, impose specific obligations for processing health data: explicit consent or alternative legal basis, mandatory DPIA completion for high-risk processing, DPO appointment, and prohibition of transfer to third countries without adequate safeguards. Violations may expose the establishment to fines up to 20 million euros or 4 % of total annual global turnover.

Health Data Hosting (HDS)

Article L.1111-8 of the French Public Health Code, derived from law n°2016-41 of 26 January 2016, requires HDS certification for any host of personal health data. The HDS certification reference framework, published by the ANS and based on ISO 27001:2022, covers six hosting activities. Any electronic signature solution editor used in a medical context must either hold HDS certification itself or subcontract hosting to a certified provider with a DPA (Data Processing Agreement) compliant with article 28 of the GDPR.

NIS2 and healthcare establishment cybersecurity

The NIS2 Directive (EU 2022/2555), transposed into French law by law n°2024-449, classifies hospitals and healthcare establishments as essential entities (EE), subjecting them to the most stringent obligations regarding cybersecurity risk management, incident notification (72 hours) and regular auditing. The electronic signature solution is an integral part of the security scope to be audited.

Concrete use cases: healthcare electronic signature in action

Use case 1: CHU Aliénor – Digitalisation of informed consents

CHU Aliénor (3,200 beds, 6 sites), facing a rate of lost or incomplete informed consent forms of 8 %, deployed Certyneo to digitalise 100 % of its informed consents in surgery and oncology. The patient receives an SMS or email link before admission, signs from their smartphone in less than 2 minutes, and the certified document is automatically entered into their medical file on the EHR.

Results after 6 months: Incomplete consent rate reduced from 8 % to 0.3 %, average collection time reduced from 48 hours to 4 hours, saving of 127,000 A4 sheets per year, GDPR compliance assured with qualified timestamping and audit trail retained 10 years.

Use case 2: MEDIPRIVÉ Group – Contracts for independent practitioners

MEDIPRIVÉ, a group of 14 private clinics in the PACA region, managed its collaboration contracts and amendments with its 340 independent practitioners via paper exchanges and PDF by email, without certified probative value. The average time to sign an amendment reached 9 working days, hindering operating schedules.

Following Certyneo deployment with API integration into their HR software, amendments are now signed in advanced signature in less than 6 hours on average. The time saving represents the equivalent of 1.8 FTE administrative staff per year, reallocated to value-added tasks. The group also eliminated any risk related to data transfers outside the EU (the former service provider hosted in Ireland with subcontracting to the United States).

Use case 3: BIOPHARMA NORD Research Institute – Clinical research protocols

BIOPHARMA NORD Institute annually manages 23 clinical research protocols requiring signature of at least 6 parties (sponsor, principal investigator, co-investigators, CPP, ANSM, establishment). Each signature had to reach qualified level (SEQ) to meet ICH E6 requirements and ANSM recommendations.

Certyneo was deployed with integration of qualified certificates via an ANSSI-referenced QTSP, enabling sequential or parallel signature workflows depending on document type. The average time to obtain all signatures for a protocol fell from 34 days to 8 days, significantly accelerating trial initiation. Enhanced traceability also facilitated audits by competent authorities.
