Since civic engagement and exploitation of OSN are vital for SC shaping , particular attention should be paid to addressing privacy and security challenges related to OSN , with the aim of developing safe and ethical SC where people will feel protected , and cultivating smart people who will be actively involved in SC . Smart people KPIs and smart living KPIs , especially those related to education and training , openness and information security , are indicative of the level of privacy and security in a city . The achievement of high values of KPIs , which will lead to the enhancement of cities ' and people 's intelligence , requires : a ) identifying and understanding the factors that affect individuals ' behavior on OSN and SC ( Section 4 ) ; b ) the understanding of differences between privacy and security threats to identify vulnerabilities that facilitate the abuse of private data ; and c ) taking necessary measures ( e.g. , revision of privacy and security legislation , software tools , specialized training and education , etc . ) to prevent and deal with them .
