Digital Signature

A digital signature is an electronic signature that may be used in various situations, for instance when it is essential to know who you are communicating with electronically.

A digital signature enhances the scope for communication between citizens and the public sector. Citizens are able to use public services all the 24 hours, and users of a digital signature may eventually replace physical documents with electronic ones. By establishing digital services and using digital signatures, the public sector will be able to offer better services to citizens and businesses, while at the same time improving efficiency in the administration.

Public Certificates for Electronic Services

In connection with our work to promote e-government, a key area is the establishment of digital signatures, also known as OCES (Offentlige Certifikater til Elektroniske Services) (Public Certificates for Electronic Services). A digital signature is based on PKI (Public Key Infrastructure). This is an infrastructure which enables authentication and confidentiality in electronic communication between two parties.

NemID

NemID is the new digital signature. You can use your NemID as secure login regardless of where you use it - whether you are accessing your online banking service, e-Boks or the local public authorities’ self-service or whether you are checking your insurance or retrieving your tax return form from the Danish tax authorities, SKAT.

NemID is comprised of two components: your password, which only you know; and a code card with one time codes, which you have in your possession. Therefore, NemID offers strong protection against intruders and hackers.
