1. Natural & Legal Persons
A natural person, e.g. an employee in home office likes to sign electronically a contract or another digital document. A person signature is suitable for this purpose.
A legal person requires a large ammout of electronic signatures for different types of files such as invoices, contracts, etc. The seal is available for this purpose.
2. Identify once – sign multiple times.
In order to use the Signing Service, the natural or legal person must be identified once with an identification application. Our Smart Registration Service (SRS) carries out this identification by using, e.g. the free Registration Authority App (RA-App), SRS Video, SRS Bank or any other existing and approved (KYC) process. The RA-App offers everyone the opportunity to independently perform face-2-face identification of colleagues, customers or partners in a company as an RA agent. Registers are additionally used to check organisation entries in case of seals.
A declaration of intent is requested for each personal signature. This declaration of intent is carried out with the authentication method defined during identification process. As standard authentication methods for the qualified signature we offer Mobile ID, Mobile ID Authenticator App with Fingerprint/ Face Recognition or a combination of password/one-time password via SMS. For seals, access certificates created by the organisation are used as a means of authentication in order to permit mass signatures.
4. Request of a signature or seal
A signature application, e.g. one of our partner’s or a self-developed application, requests a signature from Swisscom. The application creates a document hash and transmits it to Swisscom.
After authentication and declaration of intent to sign, a one-time, short-term signature certificate is issued in the case of personal signatures. As a result, it is not necessary to provide a process for revocation of certificates. Only organisation seal certificates for seals are longterm certificates (e.g. 2 years).
5. Time Stamp
In addition to the signature, a time stamp is added. The time stamp serves to verify that a signature was valid at a particular point in time and allows long-term validation of the signature after end of validity of the (short-term) certificate.
6. Signature Application
You can either integrate the Signing Service to an obtainable on the market or in-house developed signature application.
If desired, we gladly refer you to a suitable signature application of our partners. Within the application, documents to be signed are displayed and prepared for signature. By sending compressed data of the document (known as “hash values”), Swisscon has no conclusion about the document content. After the signature process, the signed hash document is sent back to the signature application, which creates a signed document based on this signed hash. A lot of standard libraries on the market support the transformation document-hash-document.
