Professional party representatives and legal representatives, who act according to the legal regulations, have a special attribute in their professional certificate that identifies them electronically as the authorised representative. On the technical side, this attribute is realised as a certificate extension and is registered as a unique object with an object identifier (OID). The OID is an essential pat of authentication and identification in eGovernment since it represents a defined attribute of the signatory such as which professional group he or she belongs to. The object identifiers are noted directly in the signature certificate and can be automatically processed during authentication using the signature, e.g., from MOA ID. The application is then able to recognise that a user is allowed to submit forms on his or her own behalf or for a third party as a representative. Since issuing and revoking a certificate is carried out by the professional organisation, a valid certificate correctly represents the professional group it belongs to and the representation authority. Advantages for the public authority when using professional representatives are:
- a comprehensive service offering, since other business forms can be submitted
- new organisational processes with more intensive contact with citizens
- less involvement in the steps during the procedure, since the professional representative only needs to intervene when necessary
On a technical level, the same data structure is used in professional representation during the login process as is used for the electronic mandate. The online mandates service of the SourcePIN register authority enters the representative's data in the mandate structure and sends it back to the authentication component of the application. This allows the infrastructure for the electronic procedure (MOA ID) to be kept as simple as possible.
