Solution security has traditionally been associated with the security of personal data. In the IoT era, however, it has transformed into the security of privacy. Violations of user privacy such as remote surveillance via smart home cameras, multimedia or baby monitors; interference in the functioning of household devices; unexpected shutdowns and the failure of everyday services that are normally available – all of this is unacceptable to the end user. At the same time, the internet of things provides tremendous opportunities for device manufacturing (including hardware components and software), telecom services and the integration market. A lack of trust in IoT solutions among end users could block or significantly slow down the realization of these capabilities.
