ISO/IEC 19944-1:2020(E)
Introduction
This document provides a description of the ecosystem of devices and cloud services and the related
flows of data between cloud services, cloud service customers, cloud service users and their devices.
These are necessary to provide guidance about how data are used on the devices in the context of the
cloud computing ecosystem and the associated location and identity issues that emerge from such use.
This document proposes a scheme for the structure of data use statements that can be used by cloud
service providers to help cloud service customers understand and protect the privacy and confidentiality
of their data and their users’ data through increased transparency of policies and practices.
This document may be used in several ways including, but not limited to:
a) by cloud service providers and application developers to guide them in describing what they intend to
do with data in their designs, so as to simplify privacy and data use reviews and to communicate this
information to non-technical departments such as internal compliance, marketing and legal teams;
b) by organisations drawing up data use statements as part of drafting cloud service agreements
and application contracts, privacy statements, etc., which could apply to documents internal to an
organisation, in addition to public or legal documents;
c) by government regulators and agencies to advise on suitable ways of describing data flow and use;
d) by those preparing information on data flow and data use for communication to the press and
the public.
This document cannot be used for compliance directly. Instead, it provides a set of concepts and
definitions, including a data taxonomy and data use statement structure, that can be used for
transparency about how data are used in an ecosystem of devices and cloud services.
This document also aims to improve the understanding of the data flows that take place in an ecosystem
consisting of devices accessing cloud services. It does this through an extended cloud computing
reference architecture (CCRA) (based on the architecture described in ISO/IEC 17789) that describes
the impact of devices on cloud service ecosystems and the impact of cloud services on devices. It also
describes the data flows that take place within the extended reference architecture.
To maintain a relationship of trust between the stakeholders of the ecosystem of devices and cloud
services and also to meet the demands of laws and regulations, it is necessary for the device platform
providers and the cloud service providers to be transparent about how they make use of the various
data types that flow within the ecosystem.
There is a particular need to provide simple and clear statements to end users about what is done
with data that relates to them. The data may be personally identifiable information (PII) and may be
sensitive, in other words, this can be a privacy issue. Cloud service customers are likely to be concerned
about how their data are used, even when the customer is an organization rather than an individual.
The cloud service customer may be a data controller, holding personal data about their employees or
their customers; in such a role, the cloud service customer has obligations relating to the processing of
that data.
To assist cloud service providers and device platform providers in being transparent about their use of
data, this document defines a simple language for making statements about data use, which can be used
to create clear notification to end users and other interested parties.
This version of ISO/IEC 19944 contains additional material which principally deals with organizational
data and the need to treat some organizational data in particular ways in order to ensure confidentiality,
integrity and so on.
To assist with this, the new concept of data facets is introduced and data facets are used to extend
the expressiveness of data use statements, including adding the concept of which individuals or
organizations have control over data.

This document provides a description of the ecosystem of devices and cloud services and the related
flows of data between cloud services, cloud service customers, cloud service users and their devices.
These are necessary to provide guidance about how data is used on the devices in the context of the
cloud computing ecosystem and the associated location and identity issues that emerge from such use.
This document proposes a scheme for the structure of data use statements that can be used by cloud
service providers to help cloud service customers understand and protect the privacy and confidentiality
of their data and their users’ data through increased transparency of policies and practices.
This document can be used in several ways including, but not limited to, the following:
a) by cloud service providers and application developers to guide them in describing what they intend to

information to non-technical departments such as internal compliance, marketing and legal teams;
b) by organizations drawing up data use statements as part of drafting cloud service agreements

c) by government regulators and agencies to advise on suitable ways of describing data flow and use;
d) by those preparing information on data flow and data use for communication to the press and
the public.
This document is descriptive and not prescriptive. It cannot be used for compliance directly. Instead, it
provides a set of concepts and definitions, including a data taxonomy and data use statement structure,
that can be used for transparency about how data is used in an ecosystem of devices and cloud services.
Providing a clear description of data flows
This document aims to improve the understanding of the data flows that take place in an ecosystem
consisting of devices accessing cloud services. It does this through an extended cloud computing
reference architecture (CCRA) (based on the architecture described in ISO/IEC 17789) that describes
the impact of devices on cloud service ecosystems and the impact of cloud services on devices. It also
describes the data flows that take place within the extended reference architecture.
Providing transparency to all stakeholders
To maintain a relationship of trust between the stakeholders of the ecosystem of devices and cloud
services and also to meet the demands of laws and regulations, it is necessary for the device platform
providers and the cloud service providers to be transparent about how they make use of the various
data types that flow within the ecosystem.
There is a particular need to provide simple and clear statements to end users about what is done with

in other words, this can be a privacy issue. Cloud service customers are likely to be concerned about how
their data is used, even when the customer is an organization rather than an individual. The cloud service
customer may be a data controller, holding personal data about their employees or their customers; in
such a role, the cloud service customer has obligations relating to the processing of that data.
To assist cloud service providers and device platform providers in being transparent about their use of
data, this document defines a simple language for making statements about data use, which can be used
to create clear notification to end users and other interested parties.
This revision of ISO/IEC 19944 contains additional material which principally deals with organizational

1 Scope
This document
— extends the existing cloud computing vocabulary and reference architecture in ISO/IEC 17788 and
ISO/IEC 17789 to describe an ecosystem involving devices using cloud services,
— describes the various types of data flowing within the devices and cloud computing ecosystem,
— describes the impact of connected devices on the data that flow within the cloud computing

— provides foundational concepts, including a data taxonomy, and
— identifies the categories of data that flow across the cloud service customer devices and cloud
