The National Commission for Data Processing and Liberties (CNIL), in its statement 98-005 of 27 January 1998, issued a favourable notice about the processing and diffusion of the DADS. Since early 2006, this authorisation is extended to the processing of all employees (and their employers). Since 2013, a decree specific to annual social data declarations (2013-506 of 14 June 2013) simplifies the situation and governs INSEE's access to DADS. The processing of personal data relating to the Nominative Social Declaration (DSN) was

initiated by Decree 2013-266 of 28 March 2013 relating to the nominative social declaration (Articles 3 et seq.). This decree is regularly updated with the latest developments in the DSN standard.

All employees database contents are "high protection"

classified, in accordance with the 28 June 2002 report about information systems security.

As far as public diffusion is concerned, any table intended for external diffusion must under no circumstances allow the direct or indirect identification of an employee, establishment or enterprise. This principle of statistical confidentiality is enshrined in french law (51-711 of 7 June 1951 Act) and european law ((EC) 223/2009 Regulation). It is specified in the European Statistics Code of Practice (principle 5).

For tables at place of residence, the criteria are as follows :

• No cell should have less than 5 employees ;

• No employee should account for more than 80 % of the payroll of the cell.

For tables at the workplace, the criteria are, in addition to the two previous criteria, the following :

• No cell should relate to less than 3 establishments (or companies) ;

• No single establishment (or company) should account for more than 85% of each surveyed quantity within the cell.

For example, a cell displaying job counts, labor hours and salaries can only be displayed if there are at least 3 enterprises, and no single enterprise accounts for more than 85% of the workforce, the aggregate labor hours or the payroll.

General audience may use a "reduced version", or "superanonymised" format, of the All employees database. These files only contain data relating to the current year. They must not allow the identification, even indirectly, of individuals or enterprises (as stated by the CNIL). To this end, some variables are only displayed by class (like salaries).

As of the 2002 vintage, the "superanonymised" files are :

• A national "Postes" (Jobs) filewith a sample size of 1/12th ;

• A national "Salariés" or "Poste principal" (Employees) filewith a sample size of 1/12th.
