A computing device receives a message. The message includes encrypted data and a cryptographic reference. The encrypted data includes physiological data of a wearer of the wearable device. The cryptographic reference includes a reference to a first cryptographic technique. The computing device determines the first cryptographic technique based on the reference to the first cryptographic technique. The computing device determines a cryptographic key. The computing device decrypts the encrypted data using the first cryptographic technique and the cryptographic key to obtain decrypted data. The computing device stores the decrypted data.

Abstract: Methods and devices for communicating sensitive data to applications are provided. A wearable device can wirelessly connect with a second computing device. The wearable device can be configured to obtain sensitive data. The second computing device can provide a first software application and a second software application. The wearable device can wirelessly receive a first request for the sensitive data from the first application. The wearable device can send a response denying the first request to the first application. The wearable device can wirelessly receive a second request for the sensitive data from the second application. The wearable device can determine whether the second request is authenticated to be associated with the second application. After determining that the second request is authenticated to be associated with the second application, the wearable device can wirelessly send the sensitive data to the second application.

Abstract: Several methods, devices and systems that provide features for improved activity sport sessions are described. In one embodiment, a multifunctional device includes an inertial measurement unit to sense movements of an activity device (e.g., a board, a surfboard, a windsurfing board, etc.) during an activity sport session and to sense at least one input for indicating a target location during the activity sport session. The device also includes at least one processing unit coupled to the inertial measurement unit. The at least one processing unit is configured to designate a target location in response to the inertial measurement unit sensing an input for indicating the target location, to record the target location, to determine a current location of the activity device, and to compare the current location and the target location. In one example, the at least one processing unit is further configured to generate a directional output if the target location and current location are different.

Abstract: A method and system for packet inspection in a near field communication (NFC) controller for secure element (SE) protection are described. In a communication device, the NFC controller can receive filtering rules that correspond to security for an applet in the SE. The NFC controller can also receive a packet with commands or instructions for the SE. The NFC controller can inspect the contents of the packet based on the filtering rules and determine whether to communicate the packet to the SE. The packet filtering performed by the NFC controller can also be based on whether the packet was received through an interface with an operating system in the communication device or through an interface with an NFC antenna. The filtering rules can be removed or disabled when an update for the applet is received and installed in the SE.

Abstract: Transferring control of a secure element between TSMs comprises a zone master key established between the TSMs that facilitates encryption of a temporary key. The TSMs create the zone master key prior to initiation of transfer of control. Once transfer of control is initiated, the first TSM establishes a communication channel and deletes its key from the secure element. The first TSM creates a temporary key that is encrypted with the zone master key established between the first TSM and the second TSM. The encrypted temporary key is communicated to the second TSM with a device identifier. The second TSM decrypts the temporary key using the zone master key and identifies the user device using the device identifier. The new TSM establishes a communication channel and deletes the temporary key from the secure element. The new TSM then inputs and saves its key into the secure element.
