Taxonomy of Threats to Ubiquitous Computing -- Cyber Crime and Their Restriction through Laws and Techniques for Protecting Security Issues and Privacy Threats -- Data Acquisition and Knowledge Management in IoT: Security Issues, Challenges and Road Map ahead -- Dynamic Access control Solution for Cross-tenancy in a Cloud Environment -- Game Theory Approach for Trust Management in the realm of IoT -- A Comparative Analysis of Machine and Deep Learning Algorithms for Intrusion Detection in WSN -- Sarcasm Detection in Online Social Network Myths, Realities and Issues -- Farmer assistive chatbot in Indian context using learning techniques.

This book extends the work from introduction of ubiquitous computing, to the Internet of things to security and to privacy aspects of ubiquitous computing. The uniqueness of this book is the combination of important fields like the Internet of things and ubiquitous computing. It assumes that the readers' goal is to achieve a complete understanding of IoT, smart computing, security issues, challenges and possible solutions. It is not oriented towards any specific use cases and security issues; privacy threats in ubiquitous computing problems are discussed across various domains. This book is motivating to address privacy threats in new inventions for a wide range of stakeholders like layman to educated users, villages to metros and national to global levels. This book contains numerous examples, case studies, technical descriptions, scenarios, procedures, algorithms and protocols. The main endeavour of this book is threat analysis and activity modelling of attacks in order to give an actual view of the ubiquitous computing applications. The unique approach will help readers for a better understanding.
