Foreword
ISO (the International Organization for Standardization) and IEC (the International Electrotechnical
Commission) form the specialized system for worldwide standardization. National bodies that
are members of ISO or IEC participate in the development of International Standards through
technical committees established by the respective organization to deal with particular fields of
technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other
international organizations, governmental and non-governmental, in liaison with ISO and IEC, also
take part in the work.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for
the different types of document should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject
of patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent
rights. Details of any patent rights identified during the development of the document will be in the
Introduction and/or on the ISO list of patent declarations received (see www .iso .org/patents) or the IEC
list of patent declarations received (see http: //patents .iec .ch).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to the
World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see www .iso

Introduction
There are many business and technical aspects relating to the processing of multi-sourced data, but
trust between cloud service users, cloud service customers and the cloud service provider(s) is a
significant market issue.
Cloud processing of multi-sourced data is in its early stages of development in the industry, and it is
anticipated that specific customer requirements will differ and will evolve over time. Industry clouds
have begun to form, and in some cases, their primary purpose is to bring multi-sourced data together
from participants in specific industry or community sectors to achieve common objectives. Trust may
be required in these scenarios because of regulations, agreements or policies attached to the data.
Processing of multi-sourced data will be essential to artificial intelligence applications along with
machine learning on financial, transportation, energy, manufacturing, agricultural and government
data. Trust in the data, in the cloud service provider(s), in the processing functions, in the outcomes and
among the parties is essential to the success of these projects.
The elements of trust described in this report pertain to Personally Identifiable Information (PII),
Organizational Confidential Data (OCD) or any other kind of data that can be a part of multi-sourced data.

5 Scenarios
5.1 Using multi-sourced data to reduce traffic deaths and injuries
Worldwide, 1,25 million people die each year from traffic-related accidents and between 20 million
and 50 million people suffer injuries. Data sets include accident data, roadway attributes, land use,
demographics, commuting patterns, parking violations and existing safety improvements. One of the
key outcomes is an "exposure model" that predicts the number of cars in a given location at a given
time. Actual measurements of traffic are very expensive while predictions using machine learning are
relatively inexpensive.
For example, In the US, where 34,000 people die annually in traffic-related accidents, a non-profit
1)
organization, called DataKind® is using data and machine learning to develop models to predict traffic
accident patterns. These patterns can then be used to determine where to focus street improvements
and predict the effect on accident rates for specific improvements. Street improvements have included
traffic signals and controls, bicycle lanes, road design and treatments.
2)
DataKind® held a DATADIVE® to bring data scientists together to transform the available data and
develop the model.
