What information is regulated? “Personal data”
The DPD’s “personal data” definition is crucial. It’s the trigger for EU data protection law requirements to kick in.
Information qualifying as “personal data” is regulated under the DPD, and all DPD rules on “personal data” apply to it.
Information which is not “personal data” or which stops being such, e.g. through anonymisation, can be handled without any DPD issues. For instance, anonymous data may be transferred freely, to the USA or elsewhere, regardless of the DPD’s restrictions on exporting personal data outside the EEA. That data might be subject to other laws, such as on confidentiality, but not the DPD.
Conversely, if information is “personal data”, the person who “determines the means and purposes” of processing that data is the “controller” of the data. Controllers who have certain connections with the European Economic Area are subject to various obligations.
These include having to register with authorities, handle personal data in certain ways, etc. There are also requirements regarding any “processor” processing personal data “on behalf of” a controller. “Processing” includes storing, holding, operating on, transmitting, disclosing or accessing data.
The DPD takes a very binary, “all or nothing” approach to data. If information is “personal data”, all data protection rules apply to it (not just some); if it’s not, none do.
Personal data in cloud computing
Now consider three types of data often encountered in cloud computing:
anonymised data
encrypted data
fragmented data (shards or chunks)
Are these kinds of data “personal data”? It depends.
