Secure Cloud: Mobile Signature as Digital Proof of Identity

The Austrian Citizen Card with Mobile Signature prevents identity theft. The new partnership laid the digital foundations for the current most secure Cloud computing solution. By doing so, Fabasoft, as leading software manufacturer and Cloud operator, took on a European-wide pioneering role. A further step on the way to secure digital business processes and services.

The booming usage of the internet poses new challenges for IT security.

A step in the direction of the best possible security and reliability for Cloud services was taken by the Austrian Federal Chancellery together with A-Trust, the only accredited provider of qualified certificates in Austria, and the European Cloud provider Fabasoft. Using the Citizen Card on a mobile phone (mobile signature) as standardized “Digital ID”, the secure and authentic use of Cloud services was able to be implemented.

Fabasoft is the first Austrian company to recognize the advantages of the digital signature in overcoming security challenges. By using “Digital ID”, users benefit from the current most secure method of identification in the internet. Simultaneously, the new application possibility in Folio Cloud represents a further milestone in the mobile signature success story.

The aim of the Austrian Federal Chancellery is to enable the integration of the practical applications of mobile signature already in use in the eGov sector into everyday business. The new cooperation delivers the basis for this. The partners are convinced that similar to the public sector, more offers will come in the future for the private sector. In particular Cloud services.

The Austria-wide unique Cloud access with „Digital ID“ requires the activation of the Austrian Citizen Card with Mobile Signature (more information under and The activation takes place in the account settings of a Folio Cloud allegro user. The Folio Cloud account is paired with the Austrian Citizen Card with Mobile Signature.

The Cloud login requires the entry of the signature password for the registered mobile number. A signature TAN is then sent via the Citizen Card security infrastructure to the registered mobile number. Only after this signature TAN has been entered does the user gain access to the Cloud (two factor authentication).

After login with mobile signature the user is marked as a trustworthy person in Folio Cloud. This gives business partners the assurance that a genuine identity is behind the Cloud account.

Decisive advantages of this system alongside the guaranteed digital identity: No additional card reader is required and the secure login also works on smartphones and tablets.

A further Cloud highlight: If you set the security level “Digital ID” in a team room, only Cloud users who are also logged in with “Digital ID” have access.

This means the highest degree of protection for Cloud access – state-guaranteed digital identity for the collaboration with business partners and the perfect security for Cloud data.
