Abstract: A data processing system (DPS) supports exchange of digital keys. The DPS comprises a communication module which, when executed by the DPS, is operable to receive, via multiple different network routes, multiple copies of a seed message from a second DPS, as part of a Diffie-Hellman key exchange process with the second DPS, wherein each copy of the seed message includes a seed value. The DPS also comprises a security module which, when executed by the DPS, is operable to perform operations comprising (a) determining a prevalent seed value, based on the multiple copies of the seed message; (b) computing a prevalence metric to indicate how many of the seed messages contained the prevalent seed value; and (c) determining whether a seed exchange portion of the Diffie-Hellman key exchange process has been successfully performed, based on the prevalence metric. Other embodiments are described and claimed.

Abstract: Systems and methods may provide for obtaining a seed value from a location on a beacon device, using the seed value to initiate generation of a pseudo random number (PRN) tree having time-dependent branches, and sending a beacon signal based on the PRN tree and a timing schedule that corresponds to the time-dependent branches. Additionally, a PRN may be received, via an out-of-band link, at an observation device, wherein the PRN is associated with a particular time period. In one example, the PRN may be used by the observation device to generate a subset of a PRN number tree that corresponds to the particular time period. The observation device may also conduct a proximity determination of whether a detected beacon signal corresponds to one or more time-dependent branches of the subset of the PRN tree.

Abstract: The invention relates to a method and apparatus for exposing (i.e. bridging) data and services offered by low power, low duty cycle transducers (e.g. sensors and actuators) in a standardized format over existing and established home networking technologies. A transducer access point is a functional component that serves as a proxy for health devices and sensors that are off/asleep the majority of the time to conserver power (e.g. battery life). The transducer access point may be implemented as a stand alone device or embedded within a computing device such as a home PC.

Abstract: Technologies for emotional modulation of natural language responses include a computing device that receives natural language requests from a user. The computing device identifies emotional features of the request and estimates an emotional state of the request by comparing the emotional features to a vocal pattern database. The computing device generates a natural language response and modulates the emotional content of the natural language response based on the emotional state of the request and the vocal pattern database. The computing device may modulate the natural language response to mimic the emotional state of the request, or to oppose the emotional state of the request. Possible emotional states include urgency, certainty, and dominance. Possible emotional features include acoustic, prosodic, and linguistic characteristics of the user request. The computing device may update the vocal pattern database based on the user request to adapt to the user. Other embodiments are described and claimed.
