Confidentiality
The sensitivity of personal information about human subjects will be readily understood and cannot be overstated. In addition to the requirements of the Data Protection Act, it will also be subject to your own written consent forms and the institutional ethics codes that govern your research activity.
However, it is entirely feasible to anonymise such data so that it may be freely and safely shared with others without violating any of the above (for example, via a public use dataset)
