Techniques and systems for unlocking a first device based on signals transmitted between the first device and a second device are disclosed. A disclosed technique includes receiving, by a first device, at least one wireless signal from a second device; transmitting, by the first device, at least one wireless signal to the second device; determining, by the first device, transit times of the at least one received wireless signal and the at least one transmitted wireless signal; determining, by the first device, one or more range measurements between the first device and the second device based at least in part on the transit times; determining, by the first device, an unlock decision based at least in part on the one or more range measurements; and causing, by at least the first device, the first device to unlock if the unlock decision is positive.

Unlocking a device

Methods to provide separation notifications are described. In an embodiment, movement is detected beyond a threshold distance from a trusted location, in response to the detecting, receiving an indication that at least one accessory device is nearby the electronic device and storing information on a status of a wireless connection with the at least one accessory device, receiving an indication that the electronic device is in transit, monitoring the wireless connection for the at least one accessory device, and upon detection of a lost wireless connection for the at least one accessory device, send a separation notification.

Separation alerts for notification while traveling

Embodiments of the present disclosure are directed to, among other things, improving data security with respect to data collection, verification, and authentication techniques associated with obtaining and transmitting identity information. For example, an identification credential may be received (e.g., via a short-range communications protocol such as iBeacon) by a first device from a second device. The credential may be associated with a second user of the second device. The first device may verify the credential and, if valid, an additional option to approve a secure communications channel may be presented at the first device. If the additional option is selected, a secure communications channel may be established between the first device and the second device.

Identity credential verification techniques

Embodiments of the present disclosure are directed to, among other things, improving data security with respect to data collection, verification, and authentication techniques associated with obtaining and transmitting identity information. For example, an identity credential may be secured using biometric information associated with a user, the biometric information being obtained using a first biometric input method of a plurality of biometric input methods. When the user is later authenticated, the authentication may be based at least in part on determining that the user has selected a biometric input method that matches the biometric input method used to secure the credential as well as providing biometric information that matches the biometric information used to secure the identity credential.

Methods, program products, and systems for using multiple sensors to determine a location fingerprint are described. A sampling device can measure RF signals detected at a train station of a transit system or a route of the transit system. The sampling device, or a location server receiving the measurements, can filter RF signal measurements using one or more readings from sensors coupled to the sampling device and that are different from RF receivers. The readings can be taken concurrently with the RF signal measurements. These readings, designated as motion cues, can include motion sensor readings, barometer readings, or magnetometer readings. Using the motion cues, the sampling device or location server can distinguish different platforms of a station of the transit system and different levels of the station, or filter out RF signal measurements that may have been inaccurate, e.g., as caused by disturbances from a train entering or leaving a station.

Location fingerprinting for a transit system

Methods, program products, and systems for building a location fingerprint database for a transit system are described. The transit system can be a subway system including underground train stations and routes where location determination using GPS signals is difficult or impossible. A sampling device can measure signals, e.g., radio frequency (RF) signals detected at the stations or on the routes. A location server can construct a location fingerprint for each of the stations and the routes. Each location fingerprint can represent expected signal measurements by a user device if the user device is located at the respective station or route. The location server can provide the location fingerprint to a user device for the user device to determine a location of the user device within the station or on the route.

Location fingerprinting for transit systems

Methods, program products, and systems for using a location fingerprint database to determine a location of a mobile device are described. A mobile device can use location fingerprint data received from a server to determine a location of the mobile device at the venue. The mobile device can obtain, from a sensor of the mobile device, a vector of sensor readings, each sensor reading can measure an environment variable, e.g., a signal received by the sensor from a signal source. The mobile device can perform a statistical match between the vector and the location fingerprint data. The mobile device can then estimate a current location of the mobile device based on the statistical match.

Modeling connectivity of transit systems

A GPS receiver comprises a crystal oscillator with a manufacturer's characteristic curve, a GPS radio, a TCO temperature sensor, and a GPS receiver software. The crystal oscillator serves as a local reference oscillator for the GPS radio. The GPS receiver software instructs the GPS radio to search radio spectrum for GPS satellite transmissions. Once the combination locks onto a minimum number of GPS satellites and produces a user position fix, the precise crystal oscillator frequency can be measured and associated with a temperature reading from the TCO to software-compensate the local oscillator in later cold-start frequency searches. A 'flat' SCXO model is piecemeal upgraded with individual calibrations as they are collected over the life of the GPS receiver. During manufacturing of the GPS receiver such flat-SCXO model begins as a device characteristic curve supplied by the crystal manufacturer.
