Requirements for a guaranteed and recognised electronic signature
How do they differ and what do you need to use them?
Not all electronic signatures are created equal. We have compared two of them.
Guaranteed electronic signature
A guaranteed electronic signature can be understood as a higher form of electronic signature. The requirements of a guaranteed electronic signature are regulated primarily by Act No. 297/2016 Coll. on Electronic Signature, as amended. A guaranteed electronic signature is digital data that the signatory creates using his/her private key and ensures the integrity and undeniability of the origin of the signed data.
According to the law, a guaranteed electronic signature is an electronic signature that meets these requirements:
- it is uniquely associated with the signatory,
- it enables the identification of the signatory in relation to the data message,
- has been created and attached to the data message by means which the signatory can maintain under his or her exclusive control.
Recognised electronic signature
According to Act No. 297/2016 Coll., on Electronic Signature, a recognised electronic signature means:
- a guaranteed electronic signature based on a qualified certificate issued by an accredited certification service provider and containing data that enable unambiguous identification of the signatory,
- a guaranteed electronic signature based on a qualified certificate issued by a certification-service-provider established outside the territory of the Czech Republic, if the qualified certificate has been issued in the framework of a service listed in the list of trusted certification services as a service for the provision of which the certification-service-provider is accredited or as a service whose provision is supervised in accordance with a regulation of the European Union.
