摘要

The method involves signing a document using a handwritten signing apparatus (1) i.e. writing apparatus, and producing a supplementary electronic validation (2) of a respective signature. A digital signature of a signed document is produced and stored according to finishing and signing for a signed document if all signatures are determined to be valid (AV). Digital signatures are stored on the apparatus, and a stored electronic certificate is retrieved and compared with a set of valid certificates, and a signature for the signed document is created when all comparisons are positive. An independent claim is also included for a device for increasing safety with the signing of documents.
