Toby -
Thanks for the draft.
I'll insert it in WD09 and post tonight.
The TC email list has seen several "Work In Progress" (WIP)
versions of WD09.
Thanks!

As we get ready for our first public review, we are still
lacking any material on privacy. A privacy section is required
for new OASIS specifications.
I have put together a first shot at this matter, almost
certainly too long, to start the conversation.
CTS and Privacy
The United Nations has defined privacy as “the presumption
that individuals should have an area of autonomous
development, interaction and liberty, a ‘private sphere’ with
or without interaction with others, free from state
intervention and excessive unsolicited intervention by other
uninvited individuals. The right to privacy is also the
ability of individuals to determine who holds information
about them and how that information is used” (UN General
Assembly 2013:15).
Electrical usage data inherently creates a privacy risk.
Published work has demonstrated that simple usage data can be
used to reveal the inner operations and decisions in a home.
Other research has demonstrated that anonymous electrical
usage data can be “de-anonymized” to identify an individual
electricity user. The more granular the data, the more
intimate the details that can be garnered from meter
telemetry.
In an amicus brief in a case on smart metering, the Electronic
Freedom Foundation testified that that aggregate smart meter
data collected from someone’s home in 15-minute intervals
could be used to infer, for example, whether they tend to cook
meals in the microwave or on the stove; whether they make
breakfast; whether and how often they use exercise equipment,
such as a treadmill; whether they have an in-home alarm
system; when they typically take a shower; if they have a
washer and dryer, and how often they use them; and whether
they switch on the
lights at odd hours, such as in the middle of the night. And
these inferences, in turn, can permit intimate deductions
about a person's lifestyle, including their occupation,
health, religion, sexuality, and financial circumstances.
These privacy concerns are linked to increased security risks
criminals may be able to access the data and use the
information to enable inferences about what people are doing
in their home or if they are away from home.
This specification describes how to share communications
beyond mere electrical usage telemetry. Communications reveal
what the user would like to buy, how much they would be
willing to spend, and future intents and plans.
System developers using this specification should consider
legal requirements under the Fair Practice Principles and the
European Union's General Data Protection Regulation. These
include:
(1)
The Collection Limitation
Principle. There should be limits to the collection of
personal data and any such data should be obtained by lawful
and fair means and, where appropriate, with the knowledge or
consent of the data subject.
(2)
The Data Quality Principle.
Personal data should be relevant to the purposes for which
they are to be used and, to the extent necessary for those
purposes, should be accurate, complete and kept up-to-date.
(3)
The Purpose Specification Principle.
The purposes for which personal data are collected should be
specified not later than at the time of data collection and
the subsequent use limited to the fulfillment of those
purposes or such others as are not incompatible with those
purposes and as are specified on each occasion of change of
purpose.
(4)
The Use Limitation Principle.
Personal data should not be disclosed, made available or
otherwise used for purposes other than those specified, except
a) with the consent of the data subject, or b) by the
authority of law.
(5)
The Security Safeguards Principle.
Personal data should be protected by reasonable security
safeguards against such risks as loss or unauthorized access,
destruction, use, modification or disclosure of data.
(6)
The Openness Principle. There should
be a general policy of openness about developments, practices
and policies with respect to personal data. Means should be
readily available of establishing the existence and nature of
personal data and the main purposes of their use, as well as
the identity and usual residence of the data controller.
(7)
The Individual Participation
Principle. An individual should have the right:
to obtain from a data controller, or otherwise,
confirmation of whether or not the data controller has data
relating to him;
to have data relating to him communicated to him, within a
reasonable time, at a charge, if any, that is not excessive;
in a reasonable manner, and in a form that is readily
intelligible to him;
to be given reasons if a request made under subparagraphs
(a) and (b) is denied and to be able to challenge such
denial; and
to challenge data relating to him and, if the challenge is
successful, to have the data erased, rectified, completed or
amended;
(8)
The Accountability Principle. A data
controller should be accountable for complying with measures
which give effect to the principles stated above.
In developing this specification, the Technical Committee has
kept in mind the need to support a developer wishing to
support privacy. Actors representing an up-stream electrical
serving entity, say a distribution system operator or
traditional utility, use the tame messages as anyone else—no
actor is inherently privileged. Messages to provide market
information or “ticker-tape” functions do not include party
IDs. General advertising of tenders, while necessary to draw
matching tenders quickly to market, may be anonymous.
The system developer should keep the privacy principals in
mind when making specific technology choices. For example,
messages between an actor and the market MAY be encrypted to
protect the privacy of people represented by individual
actors. While the transactive energy market must know both
buyers and sellers to support transaction contracts and
settlements, the developer should take steps to guard that
information. A developer may opt that each notice of contract
sent to an actor always has a counterparty of the market, so
as to protect the sources and uses of electricity.
It is beyond the scope of this specification to specify
security practices and system design form markets built using
this specification.
