In this deck from the Global Tech Jam 2018, Hiroaki Nishi presents: Smart City Community Services in Saitama City. "Smart communities, smart cities, smart towns, and similar smart terminologies are trending recently, along with the Internet of Things (IoT) and the Cloud, as popular new information and communication technologies (ICTs). This paper proposes a synergistic solution to urbanization problems from a technological perspective that is beneficial both to residents and to local government. Case studies of a smart community implementation in Saitama city are also provided, from the viewpoint of integrated smart infrastructure services."

Smart Community Data Privacy/Security
Cloud
 Share appropriately anonymized
data only
 Private data is encapsulated in
local areas
 Locally provide private services
and globally provide common
services
 Cyber attack cost becomes high

Authorized Stream Contents Analysis
ASCA (Authorized Stream Contents Analysis) for analyzing reconstructed TCP streams
 Authorized applications on gateway, switch, or router share SSL key with Cloud
 ASCA achieves SSL, gzip, chunk decode of +2 million TCP streams in parallel

12. Applications
 Protect IoT devices from intrusions by using devices located in the middle
of the Internet
 Surveillance of suspicious-looking accesses for providing proactive security
 Find and remove phishing attacks by checking routes

13. Applications
 Provide new services using user behaviors
 Solve the problem of privacy revealing and enhances the service
availability by removing privacy information
 Provide time-critical privacy-critical services at low latency by
encapsulating local data and services
