The Canadian system allows individuals to demand access within 30 days to any files, data, records etc etc which have been formed regarding yourself.
You may demand to know who has shared them and for what purposes they were shared. Someone in every company that keeps such records has to have a person on staff to accommodate your access to it all. (some exclusions for national security etc.)
I tried to access my records from Canada bethel using the approach above and was refused access (by letter) -the reason given for non compliance was that religions are not for-profit organizations (although they can and do generate enormous profits).
Europe may be forward thinking enough to include religions in their desire to protect an individuals access to his/her own information.
The WT is turning its new legal responsibility (to provide open access) into a data bonus for themselves by coercing members to quickly sign away their personal control of their own data to the Borg, thus giving the individual less not more rights to privacy and protection....seems pretty devious
