INTRODUCTION
The Internet of Things (IoT) technology is the third wave of information industry, following the
computer, communications network and the Internet. It provides the technology tools to build
an effective interactive IoT system connecting human users and the physical world, which
causes the changes in individual's daily life and also in the operations of human society. The
innovative ideas can be implemented in IoT systems creating new markets for technology-
based but user-friendly services. The technologies in the IoT systems will keep evolving with
improving the existing technology and also the insertion of new technologies.
The communications network focuses on connection and transmission, and it realizes
transmission service. The Internet focuses on information sharing, and provides services
related to information sharing. The IoT systems focus on the objective physical world,
realizing the basic sensing service and other services for the objects of interest (i.e. targets),
events, etc., in the physical world.
In order to realize the sensing of the complex physical world, an IoT system needs to have an
organized and coordinated sensing capability. For a specific target, this capability activates
relevant sensor nodes, and division of labour and cooperation strategies are applied, which is
similar to an enterprise that organizes people with required capabilities to form a project team
and completes the project with proper division of labour and cooperation. In this perspective,
therefore, it can be stated that the IoT system has socialized attributes as IoT nodes and
terminals establish an orderly socialized system.
This document comprises five main clauses. Clause 5 introduces the background and
motivations for the study of the socialized IoT system. Clause 6 discusses the essential
differences of the IoT systems compared to the communications network and the Internet.
This comparison is summarized with the key features of the socialized IoT system. Clause 7
further analyses the socialized network, socialized collaboration and socialized service, which
are designated as the three pillars of the IoT socialized attributes. Clause 8 addresses the
sensing security issue for IoT systems. Clause 9 discusses the application methods of the
socialized IoT attributes using a use case analysis, such as the intrusion prevention system or
infrastructure protection. This document provides readers with the knowledge of the socialized
characteristics and features of the IoT system, and inspires readers to adopt them in the
design of IoT systems and provision of IoT services.

5 Introduction to the socialized IoT systems
5.1 Three technological waves in ICT
Information acquisition, information transmission and information processing constitute the
three pillars of information technology. The impact of IoT technology on information
technology has caused significantly positive ripples on these pillars, which are denoted as
"three waves" as described below and also shown in Figure 1.
1) The first wave: The rise of the computer brings us to the digital world, which has changed
the way of processing data/information (D/I). The first wave is labelled as "digitalization".
2) The second wave: The rapid development of communications technology and the Internet
has created a world of inter-networking, which changes the way of transmitting D/I. The
second wave is marked as "networking".
3) The third wave: IoT technology is the third revolution in information technology, which has
changed the way of acquiring D/I. The third wave is designated as "socialization".
IoT technology has been moving forward to realize comprehensive information systems by
sensing the physical world and providing sensing services, which requires the IoT physical
and virtual entities to form an organized infrastructure in order to cooperate and collaborate
with each other to accomplish given purposes or tasks similar to the teamwork by organized
human teams. Therefore, an information system with such abilities can be characterized as a
"socialized" system resembling human social dynamics.

5.2 Resemblances between comprehensive IoT systems and human social dynamics
There exist many similarities between the comprehensive IoT system and human social
dynamics, which can be illustrated by the three hierarchical levels described below.
1) Various types of sensors – bio-mimetic sensors, electronic sensors, chemical sensors,
etc. – act as an extension of our sensory organs such as eyes, nose, ears, etc., to enable
us to explore the physical world.
2) After the D/I are received from sensors, they are transmitted via sensor networks and/or
data communication networks to D/I processing unit(s) for extracting and generating
hidden information, situational information, predictive information, decision-aiding
information, etc., by D/I aggregation, integration, fusion, mining, analytics, etc. This is
analogous to the D/I collected by the human sensor organs which are transmitted to the
brain through the human neural system for further processing.
3) In order to realize a comprehensive sensing and understanding of the physical world, the
cooperation and collaboration of the D/I processing units from various types of sensor
networks is required, which takes after human individuals in teams collaborating with each
other and sharing their information and knowledge to make better decisions with available
D/I.
From the observations made in the three hierarchical levels, resemblances, i.e. social
characteristics, between comprehensive IoT systems and human social dynamics do exist;
thus, comprehensive IoT systems built on socialized capability are called "socialized IoT
systems".
6 Key features of socialized IoT systems
The emergence and advancement of communications network and the Internet have greatly
transformed how human society operates. An IoT system is inextricably linked with the
communications network and Internet, and plays an irreplaceable role in realizing the
integration of "Operational Technology (OT)" and "Information Technology (IT)". In essence,
the key features of IoT are illustrated by comparing IoT with communications network and
Internet in terms of purpose, provided services and the connecting ways.
1) The communications network is a network which focuses on data transmission. It focuses
on the transmission of data itself and provides data delivery services.
The Internet focuses on the information sharing and provides the services related to
information sharing. The Internet takes information sharing as the core and promotes big
data services. The big data services involve analytics and data mining of a large number
of historical data and estimate or predict future trends.
---------------------- Page: 10 ----------------------
ISO/IEC TR 30174:2021 ISO/IEC 2021 – 9 –
An IoT system is a comprehensive information system with the purpose of sensing the
external physical world, and one of its major services is the sensing service. An IoT
system focuses on events occurring in the physical world that are both predictable and
unpredictable. It encapsulates data related to events (such as target, task, environment,
etc.), and it triggers decision-making process to manage the events. Thus, the IoT system
transforms "big data service" to "big event service".
2) The communications network connects people. For example, people make phone calls
and send messages through the mobile networks. As long as the network transmits voice
or text messages from one mobile phone to another, the communication between people
is completed. Communications network is concerned with the transmission of information
and network coverage. Therefore, the communications network is an information
transmission network connecting people.
The Internet connects computers. The Internet provides people with rich and constantly
updated information. People can get a plenty of electronic information by browsing news,
downloading materials and using various online multimedia services.
An IoT system connects things that exist in the complex and changing physical world. It
aims at sensing the external physical world and provides sensing services. Therefore, an
IoT system is a system providing a platform for interactions between human beings and
the objects in the physical world.
From the comparisons between the communications network and the Internet, the IoT
systems exhibit the following key features.
a) The IoT system focuses on the external physical world.
The application scenarios concerned by the IoT system come from the external physical
world. Massive sensor nodes acquire data from the physical world, and sensing nodes
form a network for the needs of information transmission and processing. In order to
achieve an effective management of the massive sensing nodes, an efficient network
organizational structure is necessary.
b) There are uncertainties for sensing targets in the IoT systems.
For the IoT system, there are many uncertainties in the temporal and spatial distributions
in target sensing. Because it is difficult for a single sensing node to achieve the all-around
coverage and continuous sensing in all-weather conditions, it is necessary to place
sensing nodes in different spatial locations, and carry out continuous real-time sensing.
Thus, the division of labour and coordination between different sensing nodes in time and
space is necessary.
Different targets have different external shapes and characteristics, and the environment
around the targets in different locations is also significantly different. A single sensing
node has limitations in functional capability and sensing ability. It is necessary to utilize a
variety of sensing nodes to realize a comprehensive sensing of the targets in order to
eliminate the negative impact of the uncertainties so that an accurate sensing of the
targets can be achieved. It facilitates the division of labour and collaboration in function
types and processing capabilities between multiple sensing nodes.
Further, changes brought by the updated information about targets, events and
environments need to be fully explored based on historical information. The prediction or
estimation of the target's future states (e.g. position, location, status, trajectory, and/or
behaviour) can be learned based on the historical trends. Therefore, a single sensing
node needs to have self-learning ability and the organized learning mechanism needs to
be established among different sensing nodes.
c) IoT system is both demand- and service-driven.
The IoT system is not driven by data, but driven by external demands. The emergence of
external targets or tasks, or changes in the environment will trigger the IoT system to
respond. The sensing approach and network topology need to be adjusted based on the
targets' current and future predicted states.

7 Socialized attributes of IoT system
7.1 General
From the above analysis on the key features of IoT systems, the challenges faced by the IoT
systems are clearly shown, and effort is being made to find reasonable and effective solutions.
The solutions for the key points of the requirements can be summarized as follows.
1) For sensing of the real physical world better, a large number of sensing nodes are needed
and IoT system needs to be built with an effective and efficient organizational structure.
2) To minimize or remove the uncertainties associated with the target being sensed by the
IoT systems, the sensing nodes in the IoT system are facilitated to form the effective
division of labour and cooperation among them. In order to improve the capability of
sensing, the IoT system should have the ability to learn and establish a learning
mechanism.
3) Driven by the goals and tasks, the sensing mode and networking topology of the IoT
systems need to be adjusted and updated in order to provide better IoT services.
Through comparative analysis, it is not difficult to find the characteristics of the system's
reasonable organizational structure, division of labour and cooperation, and service
orientation are unique to social groups. These three characteristics, i.e. socialized network,
socialized collaboration and socialized service, reflect the sensing behaviour of the IoT
system and are the bases of the socialized attributes; therefore, these are designated as the
three pillars of IoT system socialized attributes.
7.2 Socialized network
