scope:

This Recommendation provides definitions for crowdsourced and crowdsensing systems. It also outlines the requirements and general characteristics of IoT-related crowdsourced systems for the support of IoT applications and services. It identifies the risks and challenges that a crowdsourced system should take into consideration, its reference model as well as considerations regarding security, privacy and trust.

In particular, this Recommendation covers:

- the concept of the IoT-related crowdsourced system and corresponding definitions;

- the requirements for the IoT-related crowdsourced system;

- the reference model of the IoT-related crowdsourced system;

- considerations regarding security, privacy and trust of the IoT-related crowdsourced system;

- use cases related to IoT-related crowdsourced systems;

In this Recommendation crowdsourcing in IoT-related crowdsourced systems refers not to harvesting information or knowledge from the public but to hardware or services.
