Abstract: A system for predicting variability of travel time for a trip at a particular time may utilize a machine learning model including latent variables that are associated with the trip. The machine learning model may be trained from historical trip data that is based on location-based measurements reported from mobile devices. Once trained, the machine learning model may be utilized for predicting variability of travel time. A process may include receiving an origin, a destination, and a start time associated with a trip, obtaining candidate routes that run from the origin to the destination, and predicting, based at least in part on the machine learning model, a probability distribution of travel time for individual ones of the candidate routes. One or more routes may be recommended based on the predicted probability distribution, and a measure of travel time for the recommended route(s) may be provided.

Abstract: Techniques to derive or predict location context for a user of a mobile device include receiving signal data that indicates a set of one or more distinct signal sources from which signals are received at the mobile device for each of multiple different times.

Abstract: A system for the exchange of cryptographic keys includes a first peer source and a second peer system. The first peer source is capable of displaying a cryptographic key adapted to at least one of encrypt and decrypt electronic information. In turn, the second peer system capable of capturing the cryptographic key. Advantageously, the second peer system is capable of capturing the cryptographic key such that a user of the second peer system is capable of visually confirming receipt of the cryptographic key from the first peer source. For example, the user can visually confirm receipt of the cryptographic key by situating the first peer source and second peer source within a field of view of a user of the second peer system as the second peer system captures the cryptographic key.
