Management of access control in wireless networks known as smart spaces includes a framework that presents non-expert users with a consistent and intuitive interaction mechanism to manage access to devices they own in the smart space without exposing to them the complexity of the underlying security infrastructure. Access control of devices in a network can include providing an interface between a user-level tool on a first device connected to a network and security components associated with the network, communicating a passlet between the user-level tool and the interface, verifying access permission at a second device on the network where access permissions are based on the passlet, and providing a response to the first device based on the verification of the access permission in the passlet. The passlet provides access permissions based on a particular user rather than a particular device.

The disclosed embodiments relate to the design of a system that identifies a person.

An intelligent spatial reasoning method receives a plurality of object sets. A spatial mapping feature learning method uses the plurality of object sets to create at least one salient spatial mapping feature output. It performs spatial reasoning rule learning using the at least one spatial mapping feature to create at least one spatial reasoning rule output. The spatial mapping feature learning method performs a spatial mapping feature set generation step followed by a feature learning step. The spatial mapping feature set is generated by repeated application of spatial correlation between two object sets. The feature learning method consists of a feature selection step and a feature transformation step and the spatial reasoning rule learning method uses the supervised learning method.

The spatial reasoning approach of this invention automatically characterizes spatial relations of multiple sets of objects by comprehensive collections of spatial mapping features. Some of the features have clearly understandable physical, structural, or geometrical meanings.

A combination of these features, however, could characterize subtle physical, structural or geometrical conditions under practical situations. One key advantage of this invention is the ability to characterize subtle differences numerically using a comprehensive feature set.
