As part of its activities, Austria Wirtschaftsservice GmbH (aws) signs documents digitally using a legally valid mobile phone signature. The signatures themselves are based on the respective certificates of the signatories and are embedded electronically into the document. In addition, a signature image is generally used for visualisation.
A positive check against an electronic document signed digitally by one or more aws employees acts as clear proof that:
- the document has not been changed after signature (integrity).
- the document originated from the person indicated in the document ("signatory") and was signed in a legally valid manner (authenticity).
