for legally valid electronic signatures and seals in Europe (eIDAS) and Switzerland (ZertES)
Easy-to-integrate remote signatures as a service – become a partner and accompany your customers into the digital future. The Signing Service is a cloud-based service enabling our partner applications to legally sign documents electronically and to provide them with a time stamp. As a core element of digitalisation, the electronic signature is the solution to conclude online business processes.
The Signing Service is the only European signature and sealing solution that covers the two legal areas EU/EEA and Switzerland with one interface, in accordance with the eIDAS regulation and ZertES Signature Act. Our support speaks your language: German, English, French and Italian.
We offer a complete package of signature, identification and expression of intent that you can easily integrate into your processes resp. applications. We also enable you to exchange individual components as you wish, for example if you want to integrate and use your own authentication or identification solution.
Use the advantages of our market-defining technologies in the backend and remain the face to your customers with your process resp. application as before. Our white labelling option makes it possible.
During the signing process, you only transmit a hash (compressed document data) so that we can not see your document content. Processing and identity verification takes place in secure computer centres with geo-redundancy in Switzerland. Auditors constantly check that we comply with all regulations according to Swiss and EU legislation.
1. Natural 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.
2. Identify once – sign multiple times.
In order to use the Signing Service, the natural 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.
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.
4. Request of a signature
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.
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.

Portfolio of Signing Service for our partners
You offer an application or use an existing solution of a contract system and want to extend it with electronic signatures?
The integration of the Signing Service, based on a simple REST or SOAP API, enables the fast transfer of document hash values into your application and thus generates short-lived “on-demand” or “one-shot” signature certificates including free qualified time stamps for personal signatures or company seals on contract documents. These signature certificates can be issued completely remotely for both qualified or advanced level according to the EU regulation eIDAS and Swiss federal law ZertES.
In the Signing Service portfolio included are:
Electronic personal signatures
The Signing Service offers qualified and advanced electronic signatures for natural persons. Electronic signatures are suitable for signing digital contracts that are provided to the signatory via an online signature portal or an application. The advantage over a handwritten signature is that electronic signatures can ensure the integrity, authenticity and timing of the signature by one person on the digital document.
For legal entities (e.g. organisational signatures), the Signing Service offers advanced and qualified seals. Electronic seals are suitable for mass mailing of documents and invoices. In addition, an electronic seal ensures integrity, the timing of the seal by a legal entity and authenticity on digital documents.
