Abstract

In one arrangement, a first device presents a display that is based on context data, derived from one or more of its sensors. This display is imaged by a camera in a second device. The second device uses context data from its own sensors to assess the information in the captured imagery, and makes a determination about the first device. In another arrangement, social network friend requests are automatically issued, or accepted, based on contextual similarity. In yet another arrangement, delivery of a message is triggered by a contextual circumstance other than (or in addition to) location. In still another arrangement, two or more devices automatically establish an ad hoc network (e.g., Bluetooth pairing) based on contextual parallels. In still another arrangement, historical context information is archived and used in transactions with other devices, e.g., in challenge-response authentication. A great number of other features and arrangements—many involving head-mounted displays—are also detailed.

Claims20

Dependent claims

A method for authenticating a transaction between first and second devices to increase security, one of said devices being a consumer's mobile device, the other of said devices comprising a transaction terminal, the second device being equipped with a microphone to sense audio emitted by the first device, the method being performed by the first device and comprising the acts:

using a sensor in the first device, obtaining one or more context parameters of the first device selected from the list:
information based on visual stimulus recently sensed by the first device;
sensed radio transmissions;
sensed RFID data;
orientation sensor data;
magnetometer data;
acceleration sensor data;
audio classification data, received from a logical sensor fed by information both from an audio sensor and another sensor;
activity classification data;
and
barometric sensor data;
in the first device, generating an audio signal based, at least in part, on said obtained context parameter(s) of the first device;
and
presenting the audio signal from the first device, for sensing by the microphone of the second device, for use by the second device to authenticate the transaction;
wherein the audio presented from the first device can be processed by the second device to determine whether the context parameter of the first device, on which the presented audio signal is based, is consistent with a context parameter independently sensed by the second device, thereby increasing security of the transaction.
