 Encryption of data traveling over a public network (Internet) so that nobody can decipher its
contents.
 National coverage.

 Massive transfer of information.

2.2 ICT facilities: over the top, services, applications and contents

This section addresses the application and security layers illustrated in Figures 4 and 5, and contains
specifications for corresponding ICT facilities.

2.2.1 ICT integrated services capacity
The capacity of integration of services has a direct relationship with interoperability, which is
decisive. Every entity involved in the development SSC applications shall adopt open standards that
enable interoperability between information systems with the systems of other actors, public and
private, and for data captured through smart devices of citizens serve as basis for open and reuse
data and generate new services and platforms.

2.2.2 Data management
2.2.2.1 Data security

As stated in the European Commission Project SMARTIE (Secure and Smarter Cities Data
9
Management) : "A secure, trusted, but easy to use (…) system for a smart city will benefit the various
stakeholders of a smart city. This also holds true for SSC. The city administration will find it easier to
get information from their citizens while protecting their privacy. Furthermore, the services offered
will be more reliable if quality and trust of the underlying information is ensured".

There are numerous risks to be addressed involving all levels of data of the system itself, and
considering citizens' concerns about data intrusion, then security becomes a key concept in the
10
adoption and sustainability of a smart city, some of these risk are :
 Event‐driven agents to enable an intelligent/self‐aware behavior of networked devices.
 Authentication and data integrity.

 Models for decentralized authentication and trust.
 Security and trust for cloud computing.
 Data ownership, repository data management, privacy policies management and privacy
preserving technologies.
 Legal and liability issues (etc.).

2.2.2.2 Integration of heterogeneous data

The sensing of urban spaces and the participation of society in the generation of content and social
networks exponentially increases the volume of information available. There are three "V" of
interest in large data volumes (i) the Volume or the amount of processed information, (ii) the Variety
of the types of data that can be represented, and (iii) the Velocity (speed) at which are captured,
transferred and processed these data.
