SWIFT

As many news outlets report, the European Commision starts negotiations with the USA about sharing financial data from SWIFT transactions with the USA.

Once the data are in USA it will be quite hard to ensure that the data are only used as intended. The security of these data does not only depend on the present US government, but only on all future governments.

This underlines and old and wellknown rule of data security: Mimimize the amount of data given at any time. Applied to this case, give SWIFT as few as possible.
