The User Journey
![Page 6: SDC Practice in the Secure Access of the UK Data Service](https://reader036.fdocuments.net/reader036/viewer/2022062323/56815f67550346895dce6415/html5/thumbnails/6.jpg)
Training
• Required for access• Face-to-face, small groups• E-Training due Spring 2013• 3 components:
• Using the SDS
• Safety and Responsibility
• Statistical Disclosure Control

Output checking Issues
• ESSnet Standards• Analytical outputs vs secondary datasets• Final vs Intermediate outputs• Manual checking• Cross-checking • Record keeping of all released outputs• Format vs Content in rejection rate• Context dependant output checking• Secondary disclosure in data structure• Transformation of unsafe outputs to safe

Context: when are data public?
Would this map be released if it showed
• bookshops on the ONS business register?
• majority non-white neighbourhoods?
• animal research laboratories on the business register?
• Some times we don’t know:• case-by-case basis

Challenges
• Joint collaboration with researcher• Hard and fast rules vs flexibility• Unpredictable results via complex techniques• How to get efficiency, transparency, security and
consistency?
