Abstract
A method for a security system includes receiving a first location and a first time period, retrieving an access control tree having nodes associated with locations and edges coupling nodes, wherein a first node represents the first location and a second node represents a building entry, traversing the access control tree from the second node to the first node to determine an ordered list of nodes and associated time periods, storing the ordered list of nodes and an identifier associated with a user, providing to a smart device a token associated with a requested access control point, when a requested node is within the first ordered list of nodes, and authorizing with the requested access control point a physical action visible to the user in response to the requested token.
