Foreword
This Technical Report (TR) has been produced by ETSI Technical Committee Smart Machine-to-Machine
communications (SmartM2M).
Modal verbs terminology
In the present document "should", "should not", "may", "need not", "will", "will not", "can" and "cannot" are to be
interpreted as described in clause 3.2 of the ETSI Drafting Rules (Verbal forms for the expression of provisions).
"must" and "must not" are NOT allowed in ETSI deliverables except when used in direct citation.
Introduction
The present document focuses on privacy, which is particularly relevant within the IoT environment due to a series of
emerging challenges resulting from hyper-connectivity. The approach adopted builds on the fundamental assumption
that even though it is generally considered that privacy and security are separate concepts, they are actually
interconnected, and they should therefore be treated in practice in a coordinated manner. Security constitutes a
prerequisite for the effective protection of privacy, as it has also been confirmed by the General Data Protection
Regulation (GDPR).
NOTE: See also the Preamble of the Regulation (EU) 2016/679 [i.16] on the protection of natural persons with
regard to the processing of personal data and on the free movement of such data and repealing
Directive 95/46/EC (General Data Protection Regulation) [i.23].

1 Scope
1.1 Context of the present document
In order to provide a global and coherent view of all the topics addressed, a common approach has been outlined across
the Technical Reports concerned (see below) with the objective to ensure that the particularities of the IoT systems are
properly addressed and that the overall results are coherent and complementary.
In this context, the present document has been built with this common approach also applied in all of the other
documents listed below:
• ETSI TR 103 533 [i.2]
• ETSI TR 103 534 (part 1 and 2) [i.28]
• ETSI TR 103 535 [i.33]
• ETSI TR 103 536 [i.34]
• ETSI TR 103 537 [i.35]
• ETSI TR 103 591 (the present document)
1.2 Scope of the present document
The present document elaborates on how to ensure effective protection of individuals' privacy in the IoT environment. It
acknowledges the challenges for privacy and data protection and stresses the necessity for a human centred approach.
To this end, the present document will:
• highlight the role of social values in the design of IoT systems;
• discuss the role of standards under the GDPR and the proposed ePrivacy Regulation;
• outline the role of the individual, also, through a set of use cases drawn from an ongoing EU project and
further adapted for the needs of the present document;
• produce an overview of the main privacy and data protection challenges emerging in the IoT environment;
• review the privacy standardization gaps identified in ETSI TR 103 376 [i.1] and how some of these gaps have
been resolved since the completion of the work if at all;
• illustrate current best practices across industrial and other organizations in the processing of personal
information to meet, and in some cases exceed, the minimum requirements for compliance in view of
maximizing the protection of personal information;
• point at the fundamental shifts taking place in relation to privacy under EU Law, including the shift from rule-
based frameworks to principle-based frameworks, the necessity to go beyond mere compliance to meaningful
accountability and the implementation of impact-based measures.
For reasons explained below under clause 7.3, the development of new standards falls outside the scope and the
objectives of the present document.
Notably, the present document is addressed to the entire set of stakeholders with a role in the IoT environment and it
complements ETSI TR 103 533 [i.2].

10 ETSI TR 103 591 V1.1.1 (2019-10)
data concerning health: personal data related to the physical or mental health of a natural person, including the
provision of health care services, which reveal information about his or her health status [i.16]
data protection: protection of data relating to an identified or identifiable natural person. In the context of the present
report, data protection refers to personal data protection. Notably, it is largely technically feasible that non-personal
data become personal data
genetic data: personal data relating to the inherited or acquired genetic characteristics of a natural person which give
unique information about the physiology or the health of that natural person and which result, in particular, from an
analysis of a biological sample from the natural person in question
The following terms are taken from [i.3] and [i.4]:
authentication: verification of the claimed identity of an entity
availability: property of being accessible and usable upon demand by an authorized entity
data: data of any form, nature or structure, that can be created, uploaded, inserted in, collected or derived from or with
cloud services and/or cloud computing, including without limitation proprietary and non-proprietary data, confidential
and non-confidential data, non-personal and personal data, as well as other human readable or machine-readable data
data controller: natural or legal person, public authority, agency or any other body which alone or jointly with others
determines the purposes and means of the processing of personal data
data integrity: property of protecting the accuracy and completeness of assets
data portability: ability to easily transfer data from one system to another without being required to re-enter data
data processor: natural or legal person, public authority, agency or any other body which processes personal data on
behalf of the data controller
data retention period: length of time which the cloud service provider will retain backup copies of the cloud service
customer data during the termination process (in case of problems with the retrieval process or for legal purposes); this
period may be subject to legal or regulatory requirements, which can place lower or upper bounds on the length of time
that the provider can retain copies of cloud service customer data
data subject: identified or identifiable natural person, being an identifiable person is one who can be identified, directly
or indirectly, in particular by reference to an identification number or to one or more factors specific to his physical,
physiological, mental, economic, cultural or social identity
information security: preservation of confidentiality, integrity and availability of information
personal data: any information relating to an identified or identifiable natural person ('data subject'); an identifiable
natural person is one who can be identified, directly or indirectly, in particular by reference to an identifier such as a
name, an identification number, location data, an online identifier or to one or more factors specific to the physical,
physiological, genetic, mental, economic, cultural or social identity of that natural person
privacy: ability of an individual to be left alone, out of public view, and in control of information about oneself
NOTE: One can distinguish the ability to prevent intrusion in one's physical space ("physical privacy", for
example with regard to the protection of the private home) and the ability to control the collection and
sharing of information about oneself ("informational privacy"). The concept of privacy therefore
overlaps, but does not coincide, with the concept of data protection. The right to privacy is enshrined in
the Universal Declaration of Human rights (Article 12) as well as in the European Convention of Human
Rights (Article 8). (Also, see the definition in [i.4]). The concept of privacy within the context of data
protection entails that personal data is entrusted to the data controller and/or data processor. The d
