Abstract: A computer vision platform generates and maintains a digital representation of physical objects in a physical space, where the digital representation comprises objects corresponding to the physical objects and the objects comprise attributes. The attributes can include enhancer attributes, expression attributes, and state machine attributes that are specified by a user during a configuration process. In one embodiment, the computer vision platform comprises a video runtime module, a detector runtime module, an application runtime module, and an aggregation module. The video runtime module captures and processes video streams into video frames. The detector runtime module identifies and tracks physical objects and attributes in the video frames. The application runtime module builds a digital representation of objects corresponding to the physical objects, derives additional data from user-defined attributes, and builds relationships between disparate physical objects.

Abstract: In one embodiment, devices, systems, and methods provide authentication of a user using two-factor authentication to enhance security. In such embodiment, a user presents login information and a valid token, wherein the token may be generated by a portable authentication device that comprises a processor, a memory, and/or an activation interface.
