Advanced Signature
YumiSign Advanced Signing relies on cryptographic metadata and unique handwritten user signatures; The user signs by hand on the mobile device and the signature is returned in a cryptographic form as part of the chain of digital data that the mobile sends back to YumiSign. A signature must be unique and any replay is refused by the back-end. The signature is graphically applied to the orginal document and cryptographically sealed with YumiSign HSM.
Qualified electronic signature
YumiSign supports Qualified Signatures with eIDAS-Certificed signing devices like European ID cards or LuxTrust dongles. Qualified electronic signatures are done on the mobile devices and require the YumiSign card reader in order to use your eIDAS signing device. Electronic signatures with YumiSign will appear as EUTL-trusted signatures in Acrobat Reader. Unlike other signature platforms, YumiSign Qualified signing works in a "Sign what you see" mode: The document to be signed is downloaded and displayed on the mobile. The eIDAS devices will also sign what is displayed to the user. This is important because with most other platforms, only a hash of the document is provided to the signing device via a Web connection and a set of middlewares. The user can never be 100% sure he is signing what is intended to be signed (ie. what he sees on the signing platform)...
When the document is signed in advanced or qualified mode, it is sealed by YumiSign sealing HSMs to provide the proof that it has not been altered. YumiSign also applies a timestamp using certified timestamping authorities like Entrust.
