Confirm it with an e-seal

Electronic Seal is a new solution incorporated in the eIDAS EU Regulation. Using the Electronic Seal to secure evidence of electronic transactions can facilitate the implementation of electronic services for individuals, reducing the need for them to use the electronic signature.
Electronic Seal is designed to ensure the integrity and authenticity of documents sealed with it. The Seal certificate contains information, which defines what exactly does “the authenticity” of the document imply. Authenticity of an electronic document may mean that the sealed document has been created or processed in accordance with rules regulated by certificate or certification policy.
