Outline

• Current state of establishment of RA to statistical microdata in ESS, ongoing projects and available RA services

• propose a model for development of RA to statistical microdata in Croatia

• integrating the Croatian system for RA in the currently developing ESS’s infrastructure

Introduction

• National Statistical Offices - lots of microdata• Microdata - researchers’ secondary analyses,

empirical studies• growing need for researchers’ easy access to

publicly funded data• Contacts with academic institutions – strategic

resource for development of official statistics

Data throughout statistical surveys

Microdata Confidentiality

• data about individual statistical units• definitions of confidential microdata depend on

national legislation, the design of the survey (sample size, included variables) and the means of access (e.g. Remote Access, Safe Centre, Download)

• classifying recordset as confidential

Solutions for access to microdata

• No access• „on-site” access for „guest researcher”• Remote execution and advanced remote

execution solutions also called “Job Submission Systems” (24/7)

• Modern Remote Access systems

Why RA for researchers?

• Benefits for society ...• Cost/benefit• researcher’s needs.• need for Remote Access (RA) systems• high demand for confidential microdata• limited resources inside the NSIs

Available RA Centres in Europe

• Denmark, France, Slovenia, the Netherlands, Sweden and United Kingdom, offer researchers RA service

• Safe Centre - Eurostat in Luxemburg

Common RA areas

• Data does not leave RDC (outbox)• Accreditation before entering (pass, IP, OTP, biometrics,

hardware components),• Sofisticated user account management (Microsoft active

directory)• Internet ot private government network with encryption

for communication (SSTP, SSl-VPN, Cisco-tunnel, RDP (Microsoft) and ICA Basic encryption (Citrix))

• Surveillance (monitoring sessions, logs, log-on and log-off information etc)

ESS projects for RA to Microdata

• ESSnet’s DARA project – connecting Safe Centers in countries with servers in Luxemburg

• Eurostat’s VIP-SICON project – based on Citrix• Data Without Boundaries (CESSDA + ESS)

• European Commission, Digital Agenda 2020,• e-certificates

Proposal of model for RA in Croatia

• CBS, closely working with Eurostat, EU member since July 2013; Croatia is not a member of CESSDA (DwB)

• Need for beter cooperation chanels between researchers and official statistics in Croatia

• Croatian government has signed Open Government Partnership agreement in August 2011; projects: NIAS – based on OIB, e-Citizen

• CARNet, AAI

Conclusion

• Connect research community members to safely protected statistical microdata, benefits

• Progress in some European countries• Proposal for development of RA Safe Centre for

statistical microdata in Croatia• Legal restrictions, privacy and open data issues,

complex user management• Integrate Croatian System to ESS’s system for RA

to stat- microdata
