Introduction

The purpose of the brief discussion-segment within the Panel is to identify and discuss the distinction between the well-established concept of a Privacy Impact Assessment (PIA) and the newly-defined notion of a Data Protection Impact Assessment (DPIA) under EU GDPR Art.35.

A Short Definition of a PIA

"A PIA is a systematic process, which identifies and evaluates from the perspectives of all stakeholders the potential effects on privacy of a project, initiative or proposed system or scheme and which includes a search for ways to avoid or mitigate negative privacy impacts" (Clarke 2011).

A More Comprehensive Definition of a PIA

Here's a long definition from Clarke (2009).

What I think are the key issues are highlighted with '**':

"A PIA is properly distinguished from other kinds of activities by the following characteristics:

Categories of Assessment Processes

At CDPD 2014, I distinguished a dozen 'assessment categories' on the basis of their focus (Clarke 2014).

The three that are relevant to this discussion are:

Criticisms of the EU DPIA

At CDPD 2014, my criticisms of the (then) GDPR Art.33 were (Clarke 2014):

My subsequent criticism of the (now) Art.35 were (Clarke 2016):

Conclusions

My personal conclusions are that the EU notion of a DPIA falls so far short of a PIA as to raise doubts about whether it has any value as a privacy-protective mechanism.

A DPIA is merely an assessment of compliance with existing law(s).

It is not an assessment of privacy impact, nor even of data privacy impact.

Organisations are already subject to the obligation to comply with data protection laws.

So they are also already subject to an obligation to assess their compliance in advance of implementing new initiatives.

In other words, the Art.35 DPIA provisions make almost no improvements to privacy protection. At best, there may be very modest progress as a result of Art.35.7 confirming some of the actions needed ("a systematic description", and assessment of "necessity and proportionality"):

Discussion Questions
(1) Visual Surveillance

CCTV, body-worn cameras and drone-borne cameras may record data. But they can also stream data to an observer without recording it. And they can also cause people concern just by being there without being switched on - and indeed the mere possibility that they may be around is upsetting to various individuals under various circumstances.

Where visual surveillance doesn't give rise to any recorded data:

(a) can a DPIA consider the impact on the privacy of personal behaviour of:

(i) the operation of cameras?

(ii) the existence of cameras?

(iii) the possibility of the existence of cameras?

(b) *must* a DPIA ... (etc.)?

(2) Collection and Analysis of Body Tissue and Body Fluids

Substance (ab)use testing and DNA testing are being imposed in a wide variety of circumstances, including in workplaces, on highways, and in the vicinity of crime scenes.

(a) Must a DPIA consider the data-creation and data-handling practices associated with such activities?

(b) Does it make any difference if the material is collected as a result of a 'request' rather than a 'demand' backed by legal authority?

(c) Can a DPIA consider the impact of the data collection process on:

(i) the privacy of the physical person?

(ii) the privacy of personal behaviour?

(d) *Must* a DPIA ... (etc.)?
