22 Social Connectivity among Things Based on social connectivity or relations with other things, Clock can interact with different things (e.g. flight schedule), for instance, to intelligently manage and adjust people s other activities (e.g. meetings). This will be heavily relied on the cognition that IoT systems can provide. Meetings Flight Schedule Train Station Taxi Coffee Maker I95 Road Condition Gas/Charging Station Weather 2014 InterDigital, Inc. All rights reserved. Creating the Living Network 22

23 IoT Security and Privacy Google and Nest have the potential to do great things together for users and consumers, but don t expect that to happen without users giving up some more of their precious data to the search giant. All that remains to be seen is how that will happen, and what people get in exchange for that access InterDigital, Inc. All rights reserved. Creating the Living Network 23
