⭐ FEDIS: Forensic Evidence Declaration & Integrity Statement
FEDIS is Informatica in Azienda’s proprietary protocol that elevates ONE EXPRESS to professional forensic standards. We don’t just certify: we have created an internationally recognized methodology to confer maximum evidentiary value to your digital content.

⭐ ONE EXPRESS: Proof of priority, accessibility and validity over time
ONE EXPRESS doesn’t just sign a document. Through certified SHA-256 hash, RFC 3161 timestamp and FEDIS methodology, it allows you to prove that digital content already existed in a precise form at a certain date. This is the fundamental difference from traditional digital signatures: it creates proof of priority that holds up in court.
While a digital signature only certifies the moment of signing, ONE EXPRESS certifies the actual existence of the content, its integrity over time and the ability to verify it independently even after many years, without depending on proprietary software.
⚠️ Signing a file does NOT prove it existed before
Not even if you add a timestamp. In legal disputes, this difference can decide the outcome of a case.
Digital signature + timestamp
Certifies WHO signed and WHEN
ONE EXPRESS
Certifies THAT the file already existed
And this is where everything changes.
With digital signature + timestamp you can:
- ✏️ Write the file
- ✏️ Modify it
- ✏️ Immediately apply signature and timestamp
⚠️ The system only records the moment of signing. It doesn’t prove the content was already complete before.
With ONE EXPRESS instead:
🔒 The content is “frozen” forensically
It’s like pouring the file in concrete.
ONE EXPRESS doesn’t prove how long a file has existed. It proves that at that date it was already complete, identical and crystallized. From that moment, proof of priority that holds up in court is created.
💡 Practical example
• Digital signature + timestamp:
You can only prove that at 10:32 someone signed that file.
• ONE EXPRESS:
You can prove that at 10:32 that content already existed exactly in that form, because:
- ✓ A SHA-256 hash is calculated
- ✓ An eIDAS qualified timestamp is applied
- ✓ A FEDIS forensic integrity statement is produced
Tomorrow, in a year or in ten years, you recalculate the hash: if it matches, it’s the same file. Period.
This is the difference between a simple signature and true forensic certification.
Proof of Priority
You prove when the file already existed and that the current version is identical (verifiable SHA-256 hash). Not just a signature, but certified existence.
Immediate Accessibility
The file always remains openable with common tools (video, audio, images, documents). No proprietary format, no mandatory software for verification.
Validity Over Time
SHA-256 hash, RFC 3161 and TSR files are permanent global standards. The proof remains verifiable even in 10 or 20 years, without proprietary dependencies.
Qualified Third Party Authority
Timestamp issued by eIDAS qualified TSA (ETSI EN 319 421/422). The certification is objective, independent and automatically recognized in the EU.
With ONE EXPRESS you get:
- → Complete forensic certification
- → eIDAS qualified timestamp
- → SHA-256 cryptographic hash
- → Forensic integrity statement (FEDIS)
- → International legal value
📌 One file. One certification.
When you need to prove that a document, contract, communication or digital evidence already existed at a specific date, digital signature (even with timestamp) is not enough. You need forensic certification that truly holds up in court.
