Methods and apparatus for determining device location in crowded indoor environments. A mobile device is configured to determine its location using a Wi-Fi Time of Flight (ToF)-based location scheme. Once the device determines it location, it may broadcast its location to nearby devices using a low energy location sharing mechanism that employs low energy broadcast signals identifying the location of the device. The low energy broadcast signals may be used by other devices having a similar configuration, as well as devices that don't use the ToF-based location scheme to determine their locations using RSSI measurements and multi-lateration and / or have such capabilities disabled. The location of a device may be updated by fusing location data derived from the ToF-based location scheme with location data received from nearby devices that are broadcasting their locations using the low energy location sharing mechanism. The sharing mechanism reduces the number of ToF sessions, while also reducing power consumption by using the lower energy broadcasts to share location data.

A system and method for providing dynamically shared documents to multiple computing devices. In a preferred embodiment, the system includes a hub and a plurality of computing devices in physical proximity with the hub.

A secure location sharing system is disclosed that allows publishers to share their locations with subscribers. Each publishing device generates, encrypts and publishes its location information with a specified precision to a distribution service for distribution to one or more subscribing devices. The distribution service provides secure distribution of the location information to the distribution list but cannot access the publisher's precise location information, which remains encrypted until decrypted at the subscribing devices. Publishers can share their location information with varying levels of precision for different subscribers. Publishers can select at least two dimensions of location information precision: spatial and temporal. For less precise location sharing, the publishing device can randomize or obscure the precise location of the publishing device. The publisher can move a subscriber or a group of subscribers to a lower or higher level of location precision by generating new key pairs at the publishing device.
