4.1 1         Data Confidentiality Committee

The Data Confidentiality Committee deals with the problems of data confidentiality at SORS and was established as an advisory body of the Director-General of SORS.

The Data Confidentiality Committee has the following tasks:

To
  • to take care of the implementation of the Rules on
the Procedures and Measures for the Confidentiality
  • Protection of Data
Collected Under
  • collected by the
Program of Statistical Surveys by SORSTo
  • program of statistical surveys on SORS;
  • to deal with various matters and to give advice to the Director-General of SORS regarding issues that cannot be solved by general rules from the field of data confidentiality;
To
  • to report to the Director-General of SORS and the Statistical Council of the Republic of Slovenia regarding the situation in the field of data protection at SORS.

With reference to its tasks, the Data Confidentiality Committee adopts findings, positions and opinions and forwards them to the Director-General of SORS. Members of the Data Confidentiality Committee are experts from SORS and authorised authorized producers of national statistics as well as external data protection experts. Committee members are appointed by the Director-General of SORS.

4.2 2         The system of rules and procedures regarding the release of microdata to eligible users

4.2.1 1    Organizational rules and procedures

All requests received by SORS for the release of microdata are On its website SORS publishes forms of request for obtaining microdata, examples of contract provisions and declarations of data protections, which researchers need to sign.

Every researcher needs to fulfill a request for obtaining microdata. This request contains information on the research proposal (purpose of the statistical analysis, brief description of the statistical analysis, data source-statistical survey, variables from individual sources, what software will be used for statistical data analysis) and information about the researcher (name and surname, researcher’s registration number, researcher’s professional references).

A request received is then transmitted to the Data Confidentiality Committee, which prepares the opinion about the possibility of releasing the requested microdata and forwards it to the Director-General of SORS for approval. The Data Confidentiality Committee takes into account all aspects of a research proposal: the proposal itself, the sensitivity of variables requested and a mode of microdata release.

Microdata may be released only after signing the contract and the declaration of data protection by a researcher.

In preparing the data, subject matter specialists specialist must take into account the »need to know« principleknow principle«.

4.2.2 2    Rules for the release of non-anonymised microdata

 a. Release of microdata within the system of national statistics

Good practice: for implementing the Annual Program of Statistical Surveys, it is possible to exchange microdata between SORS and authorised authorized producers of the program of statistical surveys.

b. Release of microdata collected with combined questionnaires to partner institutions

In some cases SORS sends together with one of the government institutions to the reporting units a combined questionnaire, thus decreasing the burden of reporting the same or similar microdata twice to government institutions.

Good practice: SORS collects microdata with a combined questionnaire together with a partner institution only if SORS and the partner institution have a legal basis to do this and if SORS's SORS’s interest is not threatened by this method of microdata collection.

The legal basis for microdata collection by SORS and a partner institution must be printed on the questionnaire and the information letter must explain the purpose of microdata collection for the partner institutions.

c. Release of microdata to observation observations units requesting own microdata

In some cases observation observations units ask SORS for their own microdata that they sent to SORS in the past.

Good practice: if SORS has these microdata, it transmits them to the observation unit within its technical and financial capacity. For the 2002 Population Census, SORS transmits prints of scanned census questionnairesEach observation unit needs to prove its identity.

d. Release of microdata about their members to commercial and interest associations

To rationalise rationalize microdata collection and decrease the burden of reporting units, some commercial and interest associations do not collect microdata for various analyses themselves but ask SORS to transmit these microdata to them.

Good practice: SORS transmits individual microdata on a member of an association only after obtaining written consent from the member concerned.

e. Release of microdata for the purpose of interviewing

For the purpose of interviewing , SORS may transmit to registered scientific research organizations and registered individual researchers only the following personal microdata: name and family name, address, year of birth, sex and occupation (see Article 41, Para. 2 of National Statistics Act).

4.2.3 3    Rules for the release of anonymised microdata

a. Release of microdata to scientific research institutions and individual researchers

Good practice: microdata for scientific research and analytical purposes (secondary data analysis) are transmitted only to scientific research institutions and registered researchers that can prove their registration.

b. Release of microdata to researchers in government bodies

Government bodies are statistical microdata users that have great and specific needs for microdata, so SORS facilitates their work regarding policymaking by enabling them to use microdata.

Good practice: microdata are transmitted to the government body if the purpose of microdata use is research or analysis.

The request is denied if the purpose of microdata use is to determine administrative advantages or disadvantages for business entities or natural personspurposes.

c. Release of microdata to researchers of Bank of Slovenia

Good practice: microdata for analytical purposes only are transmitted to researcher in Bank of Slovenia.

d. Release of microdata to social science data archives

By transmitting microdata to data archives, SORS enables analytical and research work.

Good practice: microdata transmitted to various social science data archives have the highest level of confidentiality based on the contract between SORS and the data archive.
