.DDD File Legal Custody Software
2026 Compliance Guide: Cryptographic security, cloud storage, and evidentiary validity of tachograph data for transport audits and GDPR.
Chapter 1: Beyond Simple Storage: Legal Custody
Many transport operators confuse "saving" with "custody." Saving .DDD files on a USB stick or an office hard drive represents a massive operational risk. In 2026, regulations require tachograph data to be kept for at least **one year**, made available to the administration, while guaranteeing its integrity, authenticity, and immediate availability.
Legal custody software does more than just store; it protects the chain of custody. If a file is altered, it loses its value as evidence in court. Legal custody ensures that, during a transport inspection, the company can prove the data is the original extracted from the vehicle, shielding operator liability.
Chapter 2: The Pillars of Secure Custody
Cryptographic Immutability
Every .DDD file uploaded to TachoTools is digitally sealed. Any subsequent attempt at modification would invalidate the digital signature, alerting the company to a potential security breach or internal manipulation.
24/7 Availability and Multi-site Access
Law requires the delivery of files within a very short timeframe following an official request. Cloud-based custody allows traffic managers, regardless of their location, to send data to the Inspectorate immediately.
Strict GDPR Compliance
Tachograph data constitutes sensitive personal information. Our software ensures that only authorized personnel can access driver information, strictly complying with Data Protection laws.
Chapter 3: What happens if your storage system fails?
Data loss due to a local hard drive failure does not exempt a company from sanctions. Below are the risks of not utilizing professional custody software:
| Situation | Risk Without TachoTools | Solution with TachoTools |
|---|---|---|
| Surprise Inspection | Chaos searching for USB sticks and keys | One-click centralized download |
| Virus / Ransomware | Total loss and Very Serious fine | Redundant encrypted cloud backup |
| Dismissal Lawsuit | Evidence challenged for manipulation | Inalterable integrity certificate |
| Reading Error | Corrupt, unusable file | Immediate diagnosis upon upload |
Chapter 4: From Storage to Preventive Analysis
Legal custody at TachoTools is not a static warehouse. While we safeguard the data, our .DDD file analysis engine scans every record for infringements. If a driver exceeds driving time, the system alerts you while saving the file, allowing you to correct the situation before the administration detects it.
This "early warning" system is vital for mitigating sanctions under the new 2026 sanctions scale, where recidivism is punished with the loss of good repute.
