Signing is a part of the Signicat product Signicat Signature. Electronic signing through an integration with Signicat is flexible regarding the choice of signing method, the desired features as well as the signing process as examples. The signing process can differ, as the process can be composed to either show the documents(s) first or require the signer to authenticate first. Both of the alternatives are described here. Either way, the pending document(s) for signing is presented in the Document presenter, an responsive presenter supporting all modern browsers and that is cross device supported. The signing results in a PAdES, an PDF consisting of all the gathered information through the signing process. More about the signing result can be found here.
Through integration with Signicat electronic signing of documents can be achieved in two ways; Authentication based signing or third-party signing. Authentication based signing will be the underlying signing alternative for the signing documentation.
Authentication based signing
The first alternative, authentication based signing, is Signicat’s own signing solution and supports the use of any type of authentication method provided by Signicat, where the authentication result is used for signing. It will ensure a unified output format in accordance with EU specifications as well as a scalable, responsive signflow supporting about any modern device standards and window sizes available for consumers today. Authentication based signing enables you to sign one or more digital documents electronically by first consenting to the contents of the documents and subsequently authenticate yourself using one of a number of supported methods of authentication, including eID providers.
As the product relies on authentication, the eID providers does not need to support signing themselves. The service gathers proof of the signer’s actions, i.e. viewing the documents, consenting to the content and most importantly the authentication itself. The series of proofs is combined with each of the original documents. The result – the XAdES (XML Advanced Electronic Signatures) – is digitally signed by Signicat. Each original document result in one digitally XAdES document for each signer. Further the documents signed can be merged into a final PAdES (PDF Advanced Electronic Signatures) document using Packaging service.
Signicat also supports signing performed by the third party methods and their own signing support (for the eID methods with a signing solution embedded). This alternative do not follow the same output formats, cannot be guaranteed to support responsive signflows and will not necessarily support all of the signing functionalities.
Third-party signing can be provided with the following methods: Norwegian BankID, Norwegian Buypass ID, Norwegian Commfides, Swedish BankID, Swedish Telia E-legitimation, Danish NemID, Estonian Estonian ID (EstEID) and Spanish DNIe.
