Fundamental right to data protection

The fundamental right to data protection (§ 1 Data Protection Act 2000) implies the right to personal data privacy, e.g. the guarantee that reliable data on to a person's identity will neither be disclosed nor communicated to third parties.

Data protection and data security are issues of increasing importance in the information society. In addition to the comprehensive range of services and prompt service provision, users can be absolutely sure that any data they have communicated to the City of Vienna will be treated with adequate care and confidentiality.

Privacy Principles

  • The Vienna City Administration recognises and respects the right of all citizens to self-determination over their personal data.
  • The City Administration only collects and processes personal data that are indispensable for administrative purposes in the best interest of the citizens, and does not retain them for any longer than necessary.
  • The City Administration makes all reasonable efforts to ensure that the data processed according to the above principles are accurate and correct.
  • The City Administration makes all reasonable efforts to ensure that the data stored and processed according to the above principles are only accessible to case officers, e.g. public officials responsible for matters regarding the respective citizens, and that case officers can only access the information in performance of their official duties.
  • The use of the data must be transparent and subject to checks.

Data Processing Register

In accordance with § 4/4 of the Data Protection Act 2000, the Vienna City Administration is registered as DVR 0000191 in the Data Processing Register maintained by the Data Protection Commission.

As the Data Processing Register is generally accessible, users simply need to enter the register number DVR 0000191 to view a complete list of data applications operated and registered by the Vienna City Administration.

What kind of Information is collected, and why?

Personal data are only processed by the Vienna City Administration if they are within its competence as defined by law.

However, there are certain services for which we inevitably require some personal details, e.g. if you would like to apply for an exemption sticker allowing you to park your car in a restricted parking zone, or when you order information material.

Please note that, as a rule, we do not use the data thus obtained for any other purposes: data collected are only passed on to third parties or used for other purposes

  • if we have a legal duty to do so (for example in the case of judicial investigations into a criminal offence),
  • if this is necessary in order to provide the service requested (for example in the case of data queries for e-government services or other official tasks you want to perform online rather than taking your documents to the administrative office in the "conventional" way), or
  • if we have obtained your permission to do so.

This permission can be revoked in writing at any time. Whenever data are collected, you will be informed of this fact, and detailed information - such as the processing number of the data application - will be displayed on the respective web page. All services are available via an SSL-encrypted connection, which ensures that data cannot be viewed by third parties. When using SSL an URL starting with "https://" will be displayed in your browser's address line.

We do not actively gather or search for personal information. However, we would like to point out that our computing centre automatically retains the IP addresses and domain names of users accessing our web pages so it can it can trace any errors that may occur. This information needs to be processed as part of the system's internal administration in order to maintain safety of operation. The data retained are essential for the functioning of our firewall, which protects our system and thus also the data of all users from unauthorised access. In fact, Section 14 of the Austrian Data Protection Act (Datenschutzgesetz 2000/DSG 2000, Austrian Federal Law Gazette part I No. 165/1999) stipulates that every controller must take adequate precautions.

The information retained is also used for purely statistical evaluations to assess the quality of our web pages, which enable us to improve our web-based service to you.
