Abstract: A reader configured to perform dual-factor authentication is provided. The reader is configured to analyze credential data as well as event-based user inputs. The event-based user inputs are received in response to the reader presenting one or more events to a user and monitoring the user's reaction thereto. Utilization of an event-based user input enables the reader to perform dual-factor authentication without necessarily being provided with a keyboard or other advanced user input device.

Abstract: Authentication systems and methods for a population of devices each associated with an RFID tag are described. For each device, a secret key is combined cryptographically with a publicly-readable unique identifier (UID) of an RFID tag to obtain a unique authorization signature. The RFID tag is prepared utilizing the unique authorization signature as memory-access and/or tag-operation password(s). The systems and methods may safeguard against attacks whereby compromise of a single tag will not compromise the entire population of devices and may reduce or eliminate the use of inappropriate surgical devices during a surgical procedure.

Abstract: A local area network includes a number of IP capable phones which send and receive packets of audio or other information to each other over the network. Some of the phones can be wired to the network and some of the phones can be wirelessly connected to the network. The network also includes one or more access points that serve as the interface between the network and the wireless phones and the network can include some sort of switching device, such as a router. In the event that one of the phones sends a packet of audio information to another phone and the packet is marked with an incorrect timestamp value, the phone receiving the incorrectly timestamped packet is able to correct the timestamp value so that the phone can process the packet of audio information.
