DESCRIPTION:Have you ever heard of the term "geofencing"? It’s a mechanis
 m that allows limiting various types of access to a specific area. It ofte
 n uses GPS or cellular information to decide whether a user should be gran
 ted access. Computers typically lack the necessary hardware to handle GPR 
 and cellular signals\; therefore\, geo-fencing is not applicable to statio
 nary computers and laptops. …but what if we could use only the hardware 
 that’s already built into the device\, and at the same time increase sec
 urity?\n\nEnter context-based authentication\, a technology that can autho
 rize you using just a built-in Wi-Fi chip. CBA uses CSI (Channel State Inf
 ormation) to create a virtual fingerprint of the nearby environment\, whic
 h can later be used for authentication. The solution offers greater securi
 ty than traditional geofencing\, and it’s much harder to spoof since it 
 relies on data from many surrounding devices.\n\nDuring this talk\, you’
 ll have a chance to see CBA in action and explore the interesting stack be
 hind it. We’ll also share some of the advancements we’ve made in the C
 rosscon project.
