Social structures influence human behavior, including movement patterns. This research develops a "colocation" network to differentiate the mobility patterns of an individual's social ties from those of non-socially connected individuals who visit the same location at similar times. Using entropic measures, the study analyzes and bounds the predictive information of an individual's mobility pattern and its flow to both social and non-social ties. While social ties generally provide more information, a significant amount of predictive information is also present in the aggregate of non-social colocators. This information flow raises privacy concerns regarding data sharing through mobile applications.
