What is an electronic seal?

An electronic seal is technically the same as an electronic signature. The difference is that an electronic signature can be associated to both a natural person or legal person/entity, whereas a seal is associated only to a legal person/entity. The signing key must be under the sole control of the signatory and the seal key must be under control of the process creating the seal.

For electronic seals, like electronic signatures, the EU regulation on eIDs and trust services (eIDAS) describes similar requirements and legal implications for Advanced Electronic Seals, Qualified Electronic Seals and Qualified Electronic Seal Creation Devices.
