There are numerous mechanisms in place to ensure the privacy, security, quality and integrity of data in all impDAT studies.
Through the use of standardised, centrally administered tables, impDAT does not allow the entry of invalid or unknown values, it is ensured that only valid
data can be entered and later evaluated.
Privacy is ensured by only exporting anonymised data for the study, patient numbers are changed and patient names and addresses, doctors' details and
comment fields etc. are not exported.
When data is exported for a study, the exported data includes unique identifiers for the study and for each participant, thereby avoiding the possibility of
one source contributing several times to the same study, which would distort results.
The exported data is compressed (to minimise transmission time to the internet), encrypted and guarded with multiple checksums to guarantee that only
valid, untampered data can be submitted to the study. These mechanisms make it virtually impossible for unauthorised access to or manipulation of the exported
data in any way.
Evaluation of study data is controlled by password when accessing the internet or by a special encrypted protocol when the evaluation is initiated
from within impDAT itself, ensuring that no unauthorised party can gain access to any data.
