In this work, we examine the impact of Treadmill Assisted Gait Spoofing (TAGS) on Wearable Sensor-based Authentication (WSGait). We consider more realistic implementation and deployment scenarios than previous study, which focused only accelerometer sensor a fixed set features. Specifically, situations in WSGait could be using one or sensors embedded into modern smartphones. Besides, it differe...

Social tagging is an emerging methodology that allows individual users to assign semantic keywords to content on the web. Popular web services allow the community of users to search for content based on these user-defined tags. Tags are typically attached to a whole entity such as a web page (e.g., del.icio.us), a video (e.g., YouTube), a product description (e.g., Amazon) or a photograph (e.g....

Radio frequency tags allow objects to become self-describing, communicating their identity to a close at hand RF reader. Our goal is to build a radio frequency identity and geometry (RFIG) transponder that can also communicate geometry, inter-tag location history or context-sensitive
