Abstract
High profile breaches of data security in government and other organizations are becoming an increasing concern amongst members of the public. Academic researchers have rarely discussed data security issues as they affect research, and this is especially the case for qualitative social researchers, who are sometimes disinclined to technical solutions. This paper describes 14 guidelines developed to help qualitative researchers improve the security of their digitally-created and stored data. We developed these procedures after the theft of a laptop computer containing highly sensitive data from the home of a fieldworker. This paper introduces the ‘principle of proliferation’: digitally-created and stored files (like voice recordings of interviews and text files of their transcriptions) tend to proliferate during the course of a research project by virtue of fact that they can and are copied and shared as research progresses from data collection through to analysis and archive. Our guidelines were designed as concrete strategies that researchers embarking on a project can employ, particularly researchers working in teams, to accommodate this proliferation and reduce it where possible.
