Qualified Timestamping:
How does it work?
Timestamping is a process that cryptographically associates a real-time date and time with a document, event, or certain digitally performed operations such as sending an email or taking a photo. This association relies on a timestamping token, which acts as a digital seal, ensuring the integrity of the information by marking the exact moment of its creation or modification.
No matter the format of your data or the type of file you use, Evidency’s qualified timestamping adapts to all!
Don’t limit yourself: ensure the traceability and integrity of your information, whether in the form of text documents, images, videos, or others. With our solution, benefit from total flexibility to secure all your digital data, without exception.

FAQ
Timestamping
What is qualified timestamping?
Definition of qualified timestamping: A qualified timestamp is a digital proof mechanism that cryptographically associates an exact date and time with a document or digital event.
This process guarantees the document’s date and integrity, meaning it has not been altered since the timestamp was applied, and ensures its legal validity in accordance with the European eIDAS Regulation.
What are the requirements for an eIDAS qualified timestamp?
Under the eIDAS Regulation, a qualified timestamp must meet the following conditions:
- It must bind the date and time to the data in such a way as to exclude any possibility of undetectable modification, thereby guaranteeing data integrity.
- It must rely on an accurate time source based on Coordinated Universal Time (UTC).
- It must be electronically signed using an advanced electronic signature or sealed with an advanced electronic seal issued by a qualified trust service provider.
Why use a qualified timestamp?
A qualified timestamp makes it possible to:
- Guarantee the certified date of a document: providing proof of when it was created or when an event occurred.
- Guarantee the integrity of digital documents by proving that they have not been altered since their creation.
- Ensure the legal compliance of electronic documents, granting them probative value recognised across the European Union.
- Facilitate audits and inspections by providing a reliable and verifiable trace of digital events.
How does qualified timestamping work under the eIDAS Regulation?
First, a unique identifier is generated using a hashing function. This creates a digital fingerprint (hash), unique and reliable, representing the data.
This fingerprint is then transmitted to the qualified Time Stamping Authority (TSA), such as Evidency, which attaches the exact date and time based on Coordinated Universal Time (UTC). The combination of the fingerprint and time is secured by a timestamp token, a signed certificate containing:
- the digital fingerprint of the data
- the UTC date and time
- the seal of the timestamp token
The seal of the token identifies the electronic timestamp service provider that issued it and guarantees its link to the token. This seal is generated with the TSA’s private key and can be verified with the public key provided to the user via the electronic timestamp certificate, ensuring both data integrity and the legal validity of the timestamped document.
What is the difference between qualified and non-qualified timestamping?
A qualified timestamp provides maximum legal security, is issued by a qualified trust service provider, and enables data integrity to be proven before a court of law.
A simple or non-qualified timestamp only records a date and time, without any guaranteed legal value.
What are the benefits of qualified timestamping for businesses?
Qualified timestamping enables businesses to:
- Prove the date of issue of a document or event
- Protect the integrity of data and digital documents
- Strengthen the legal security of transactions and contracts
- Ensure regulatory compliance with eIDAS standards, required in certain sectors
- Optimise document management with application or enterprise-level certified timestamps, automatable via API
What types of documents can benefit from qualified timestamping?
Any digital document requiring legal proof or traceability can be timestamped, such as contracts, electronic invoices, financial documents, internal reports, legal correspondence, and more.
How to choose a qualified timestamp service provider?
Choosing a Qualified Trust Service Provider (QTSP) is essential to guarantee the legal validity of your electronic documents. Key criteria to consider include:
- eIDAS compliance: the provider must be certified under the European eIDAS Regulation, ensuring the legal recognition of qualified timestamps in all EU Member States.
- Smooth integration: opt for a solution offering a flexible, well-documented API that can easily integrate with existing systems (ERP, CRM, etc.) without disrupting business processes.
- Automation: the ability to automate timestamping via API is vital for handling large volumes of data, reducing human error and improving operational efficiency.
- Secure test environment: ensure the provider offers a dedicated sandbox environment to test the solution safely before deployment, ensuring a smooth roll-out.
- Comprehensive technical documentation: clear and detailed documentation facilitates integration and use of the solution, reducing deployment time and costs.
- Sector adaptability: the provider should offer solutions tailored to the specific needs of your industry, whether finance, healthcare, legal, construction, or others.
- Transparent pricing policy: clear and predictable pricing allows for accurate cost control and avoids unexpected charges.
By following these criteria, you can select a qualified timestamping provider that meets your technical, regulatory, and budgetary needs.
How does qualified timestamping support regulatory compliance for businesses?
Qualified timestamping is an essential tool for Legal Departments (CLOs) in the context of digital transformation. It enables organisations to meet regulatory compliance requirements, particularly in highly regulated sectors such as finance, healthcare, and construction.
It is an effective means of securing digital transactions, reducing legal risks, and reinforcing stakeholders’ trust in the company’s digitised processes.
