How can the long-term authenticity of electronic documents be ensured?
The authenticity of the electronic signature is ensured by eIDAS compliance, time-stamping and certified technology.
eIDAS compliance
Electronic signatures comply with European Union regulations and are legally recognised.
Time stamp
The time stamp certifies the authentic date on which the document was signed, thereby enabling its legal effect to be verified.
Certified technology
Independent certification guarantees that the technology used complies with legal and technical requirements.
Due to the discontinuation of AVDH and the limited usability of the DÁP eSignature (available only to private individuals), qualified electronic signatures are becoming increasingly important for businesses.
Did you know?
A significant proportion of the time stamps issued by the Hungarian public administration are generated using Polysys® software.
