Anonymisation of personal data _ Best practice


Hi KoBos,
we are working with KoBoCollect and looking for an option to anonymise personal data before (or after submission). The target is to exclude the possibility to identify a household. As we work with refugee data, even an important security reason.
Examples are: Names of head of household and household members, gps coordinates of household. This data are needed during the interview, even referenced in some qustion labels, like: What is the age of ${person}?
(The question is partly related to a former topic, where we found out that we cannot set KoBo variables, see Setting values for KoBoCollect internal variables. )
We know about the KoBo option of encrypting the whole data, but this will still show the personal data in briefcase, and creates disadvantges for data validation online (on server).
Kind regards
